Published 2026 market data suggests that a professionally installed CCTV system can range from several hundred pounds for a straightforward installation to well over £1,500 for larger or more complex systems. In London, the final cost can vary considerably depending on the number and specifications of cameras, property layout, cable routes, recording requirements, and installation complexity.
The most important thing to understand is that there is no meaningful single price for "CCTV installation".
A two-camera system protecting the entrance and rear access of a terraced house is a fundamentally different project from eight 4K cameras covering a detached property, warehouse or commercial building.
That is why this guide uses independent UK and London market data to explain realistic pricing rather than quoting one headline figure.
⬛ THE QUICK ANSWER
Current Checkatrade marketplace data for London lists:
£733
Average CCTV installation
Published range: £520 – £1,053
£872
Average CCTV supply and installation
Published range: £617 – £1,248
However, there is substantial variation within London.
For example, Checkatrade currently lists Westminster's average CCTV installation cost at £1,002, while its published average for Romford is £733.
Independent UK data from MyBuilder gives another useful benchmark:
Single-camera system: £100 – £350
Four-camera system: £800 – £1,100
Eight-camera system: £1,000 – £1,700
These figures are market benchmarks from third-party pricing platforms. They are not AZ Electrical prices and should not be treated as an AZ Electrical quotation.
Every property should be assessed based on the equipment, coverage, and installation actually required.
🟥 IMPORTANT: THESE ARE NOT AZ ELECTRICAL PRICES
The figures throughout this guide have been taken from independent published market sources including Checkatrade, MyBuilder and Which?.
They are included to help homeowners and businesses understand the factors that influence CCTV installation costs.
AZ Electrical does not operate from the pricing figures in this article.
A CCTV quotation should be based on the actual property, camera locations, security requirements, recording specification and installation work involved.
If you would like an assessment for your property, you can discuss your requirements directly with AZ Electrical's CCTV installation team.
How Much Does CCTV Installation Cost in London in 2026?
London is not one uniform CCTV market.
Property types, access, parking, building height, cable routes and the complexity of installations vary enormously between different parts of the capital.
Current Checkatrade figures demonstrate the spread clearly.
London Overall
Installation: £733 average
Published range: £520 – £1,053
Supply and installation: £872 average
Published range: £617 – £1,248.
Westminster
Installation: £1,002 average
Published range: £724 – £1,408
Supply and installation: £1,217 average
Published range: £860 – £1,747.
Ealing
Installation: £952 average
Published range: £554 – £1,631
Supply and installation: £1,115 average
Published range: £720 – £1,744.
Romford
Installation: £733 average
Published range: £520 – £1,053
Supply and installation: £872 average
Published range: £617 – £1,248.
🟥 WHAT THE LONDON DATA ACTUALLY TELLS US
The important lesson is not that somebody in Westminster should expect to pay exactly £1,002.
The important lesson is that published CCTV installation costs can vary substantially even within the same wider London market.
A postcode alone does not determine the price.
It can be associated with other factors that affect the amount of work required, including:
Building type
Property size
Accessibility
Camera height
Cable routing
Parking and loading restrictions
Installation complexity
Equipment specification
Number of cameras
Recording requirements
The figures above should therefore be treated as budgeting benchmarks rather than quotations.
Checkatrade itself says costs vary according to system type, number of cameras and complexity.
How Much Does a 4-Camera CCTV System Cost?
A four-camera installation is one of the most useful reference points because it can provide suitable coverage for many ordinary residential properties and smaller businesses.
MyBuilder's January 2026 CCTV cost guide gives a typical range of:
£800 – £1,100
Standard four-camera CCTV system.
Checkatrade provides a similar benchmark.
Its current CCTV cost guide says prices start from around:
£800 + VAT
for a basic four-camera wired CCTV system supplied and installed.
The same Checkatrade guide breaks its example down into approximately £300 supply-only for a basic four-camera wired system plus around £500 for cabling and installation.
These figures are useful because two different pricing sources arrive in broadly similar territory for a straightforward four-camera setup.
That does not, however, mean every four-camera installation should cost the same.
Four inexpensive cameras mounted at ground-floor level with easy cable access are not equivalent to four high-resolution cameras mounted at height with concealed cabling and a substantial NVR storage requirement.
What Could Four CCTV Cameras Cover?
A typical home might use four cameras to monitor:
Camera 1 — Front Entrance
Designed to capture people approaching or entering the property.
Camera 2 — Driveway
Focused on vehicles, gates and the main approach.
Camera 3 — Side Access
Covering a side gate or passage that may otherwise create a blind spot.
Camera 4 — Rear Entrance or Garden Access
Protecting vulnerable rear doors or access routes.
The important point is that the correct number of cameras should be determined by coverage rather than by buying a package containing a convenient number.
A well-positioned three-camera system can sometimes provide more useful security than six poorly positioned cameras.
How Much Does an 8-Camera CCTV System Cost?
Larger properties and commercial premises may require significantly more coverage.
MyBuilder's 2026 guide places a comprehensive eight-camera system at approximately:
£1,000 – £1,700.
Checkatrade gives a basic eight-camera wired system benchmark of approximately:
£1,000 + VAT
including installation.
Its guide lists a basic eight-camera wired system at around £500 supply-only, with cabling and installation shown separately at around £500 in its example cost table.
Again, these are basic market benchmarks.
An eight-camera installation could become considerably more expensive where the specification includes:
High-resolution IP cameras
4K recording
Long-range night vision
Larger hard drives
Multiple buildings
Fibre or network links
PTZ cameras
Advanced analytics
Long cable runs
Specialist access equipment
Integration with other security systems
What About a 2-Camera CCTV System?
Two-camera systems can suit properties where the risk areas are very clearly defined.
For example:
Camera 1: front entrance and driveway
Camera 2: rear entrance or side access
MyBuilder lists a basic single-camera setup at approximately £100–£350, but scaling that figure directly to calculate a two-camera system would be misleading because CCTV installations include shared costs such as recorders, setup, cabling and configuration.
This is why "price per camera" becomes less reliable when comparing complete systems.
Adding the fourth camera to an existing NVR may involve less additional work than installing the first camera, recorder, network connection and viewing software.
⬛ CCTV COSTS ARE NOT LINEAR
Four cameras do not necessarily cost exactly twice as much as two cameras.
A complete CCTV installation can contain shared infrastructure including:
NVR or DVR
Hard drive storage
Network equipment
Power supplies
Mobile app configuration
System commissioning
Cable routes
Internet connection
Display equipment
Once some of that infrastructure exists, adding another camera may not double the overall project cost.
Conversely, one particularly difficult camera position can add disproportionate labour and access requirements.
How Much Does Professional CCTV Installation Cost Per Camera?
MyBuilder gives an approximate professional installation benchmark of:
£100 – £300 per camera
depending on the complexity of the installation and local labour rates.
That figure should be interpreted carefully.
It does not mean a professional installer should simply multiply the number of cameras by £100 or £300.
The total project may also include:
Surveying
Recorder setup
Hard-drive configuration
Cable installation
Network configuration
Remote viewing
Camera adjustment
Testing
User setup
System handover
For larger installations, it is much more useful to compare complete system specifications than an isolated per-camera labour figure.
Wired vs Wireless CCTV: Which Costs More?
One of the biggest pricing decisions is whether the system is primarily wired or wireless.
Wired CCTV
A wired system normally involves physically connecting cameras to the recording or network infrastructure.
The installation can require:
Drilling through walls
External cable routes
Internal cable routes
Trunking
Concealed wiring
PoE cabling
Access to lofts or ceiling voids
Network cabinet work
The advantage is that correctly installed wired systems can provide a stable connection and do not depend on each camera communicating over household Wi-Fi.
Checkatrade currently puts a basic four-camera wired system at approximately £800 + VAT supplied and installed, and an eight-camera basic wired setup at around £1,000 + VAT.
Wireless CCTV
Wireless can reduce some physical data cabling requirements.
Checkatrade gives example supply-and-installation figures of around:
Four wireless cameras: £450 + VAT
Eight wireless cameras: £750 + VAT
However, the word wireless can be misleading.
A Wi-Fi camera may still require electrical power.
Battery-powered cameras introduce battery life and charging considerations.
And every wireless CCTV system depends on the quality of the network carrying its traffic.
🟥 WIRELESS DOES NOT AUTOMATICALLY MEAN "NO WIRES"
A camera can communicate wirelessly while still requiring:
Power cable
or:
Periodic battery charging
It may also need a sufficiently strong Wi-Fi signal at the camera location.
For properties with weak outdoor Wi-Fi or multiple cameras, network improvements can become part of the overall security project.
AZ Electrical also provides Wi-Fi installation and structured data cabling where security systems depend on reliable network infrastructure.
Analogue CCTV vs IP CCTV Costs
The type of camera technology also changes the budget.
MyBuilder's 2026 guide currently gives indicative equipment ranges of approximately:
Analogue Cameras
£50 – £200 per camera
IP Cameras
£100 – £500+ per camera
Wireless Cameras
£100 – £350 per camera.
These are equipment benchmarks rather than complete installed prices.
An IP system may cost more at camera level but can provide capabilities such as:
Higher image resolution
Network connectivity
PoE power
Remote management
Digital analytics
Flexible recording options
Easier integration with wider networks
The right choice depends on what the footage needs to achieve.
What Does CCTV Resolution Do to the Price?
Not all CCTV cameras produce the same quality of evidence.
Higher resolution generally means more detail.
But it can also mean:
More expensive cameras
More network bandwidth
Greater storage requirements
Larger hard drives
Higher recorder specification
A homeowner who wants to know whether someone entered the garden has a different requirement from a business that needs to identify a face or read identifying detail at a specific distance.
Paying for resolution that cannot achieve the required identification because the camera is incorrectly positioned is poor value.
Equally, installing a low-resolution camera covering too large an area can produce footage that looks acceptable on a phone but provides little useful detail when an incident occurs.
Is 4K CCTV Worth Paying More For?
4K CCTV can provide significantly more image detail than lower-resolution systems, but higher resolution is only one part of image quality.
Actual results also depend on:
Lens choice
Distance to the subject
Lighting
Night-time performance
Compression
Camera angle
Frame rate
Recorder settings
A properly designed lower-resolution camera covering a narrow entrance can sometimes provide more useful evidence than a 4K camera trying to monitor an entire street.
The question should therefore be:
"What image quality do I need at the point where identification matters?"
rather than:
"What is the highest megapixel number I can buy?"
How Much Do PTZ CCTV Cameras Cost?
PTZ stands for pan, tilt and zoom.
These cameras can mechanically move and can be useful across larger spaces such as yards, car parks and commercial sites.
MyBuilder's separate 2026 security-camera pricing guide puts PTZ camera equipment at approximately £150–£700 per camera, depending on specification.
PTZ cameras are not automatically a replacement for several fixed cameras.
A PTZ camera can only look in one direction at a particular moment unless it is operating a programmed tour.
For security-critical areas, fixed cameras may still be required to maintain continuous coverage.
What Does CCTV Storage Cost?
Storage is one of the most overlooked parts of CCTV pricing.
The important question is not simply:
"Does it have a hard drive?"
It is:
"How much useful footage can the system retain at the required recording quality?"
Storage requirements increase according to:
Number of cameras
Camera resolution
Frame rate
Compression method
Continuous vs motion recording
Hours of operation
Desired retention period
A system recording eight high-resolution cameras continuously will require far more storage than two cameras recording only when movement is detected.
Checkatrade's general cost guide describes basic wired systems as recording to local hard-drive storage and notes that storage choice forms part of system specification.
Local Storage vs Cloud Storage
There are two broad approaches.
Local Recording
Footage is stored on equipment at the property, such as an NVR or DVR.
Advantages can include:
No routine cloud-storage subscription
Central recording
Greater control over retention
Potential operation without external cloud access
Cloud Recording
Footage is uploaded to a provider's servers.
This may provide:
Off-site storage
Convenient app access
Event-based recordings
Simplified remote viewing
But subscriptions can become part of the long-term cost.
Which?'s 2026 outdoor-camera guidance warns consumers to account for subscription fees and says video-storage costs across wireless cameras and other smart-home devices can exceed £100 per year in some cases.
🟥 THE PURCHASE PRICE IS NOT ALWAYS THE TOTAL COST
When comparing CCTV systems, consider:
Initial equipment
Installation
Storage
Subscriptions
Network requirements
Maintenance
Replacement batteries where applicable
Future expansion
A system that appears cheaper on day one may have higher ongoing cloud or subscription costs.
A more expensive locally recorded system may have higher initial hardware costs but fewer recurring storage charges.
The correct comparison is therefore total ownership cost, not simply the camera price.
How Much Does CCTV Maintenance Cost?
CCTV should be regarded as technical equipment rather than a fit-and-forget purchase.
Checkatrade's cost guide gives an annual monitoring/maintenance benchmark starting around £100, while MyBuilder's 2026 guide gives annual checks and minor maintenance at around £50–£100.
These are generic marketplace figures rather than AZ Electrical prices.
A maintenance visit may need to consider:
Camera image quality
Lens cleanliness
Physical camera position
Recording
Hard-drive condition
Correct date and time
Remote access
Firmware
Network connectivity
Night-time image
Motion detection
Exporting footage
For commercial systems, maintenance requirements can be more involved because larger systems may include substantially more equipment and operational dependencies.
Why Can CCTV Installation Cost More in London?
Checkatrade's own national CCTV cost guide specifically notes that major-city location can increase installation cost.
But the practical explanation goes deeper than "London labour costs more".
London CCTV projects can involve:
Tall or Difficult Buildings
Cameras on upper storeys or difficult elevations can require more installation time and access equipment.
Terraced Properties
Cable routes can be restricted by party walls, finished interiors and limited external access.
Flats and Apartments
Shared areas, management-company requirements and restricted cable routes can complicate installation.
Commercial Premises
Working around customers, staff and business opening hours can alter the installation method.
Listed or Sensitive Buildings
Cable routes and external fixtures may require much more consideration.
Parking and Access
Loading equipment or working in restricted streets can be less straightforward than at a suburban property with private parking.
The range between current Checkatrade figures for areas such as Westminster, Ealing and Romford illustrates how wide local marketplace pricing can be.
Does Camera Height Affect CCTV Installation Cost?
Yes, potentially.
Checkatrade identifies cameras in difficult-to-reach locations, including high walls or eaves, as a factor that can increase installation cost.
Height affects more than labour.
It can change:
Access equipment
Cable routing
Installation time
Future maintenance
Camera angle
Image perspective
Mounting a camera as high as physically possible is not necessarily better security.
A camera mounted too high may produce excellent footage of the top of someone's head while failing to capture useful facial detail.
Good positioning balances security, identification, tamper resistance and maintainability.
Why Cable Routes Matter So Much
Cable routing can be one of the biggest differences between a straightforward installation and a complex one.
Consider two otherwise identical four-camera systems.
Property A
All four cameras are mounted near accessible loft space.
Cable routes are short.
The recorder is close to the router.
There is easy external access.
Property B
Cameras sit on four different elevations.
Internal decoration prevents visible cables.
The recorder is in a distant office.
Several walls must be crossed.
The internet router is on another floor.
The cameras require difficult access.
Both properties have four cameras.
But the installation is clearly not the same job.
This is why comparing quotes solely by camera count can be misleading.
Does CCTV Need Internet?
Not necessarily.
A locally recorded CCTV system can record footage without relying on the internet.
However, internet connectivity is commonly needed for features such as:
Remote smartphone viewing
Off-site alerts
Cloud storage
Remote support
Some smart functions
The local network is still important for IP CCTV even where footage is stored locally.
For larger properties, professional networking can be an important part of a reliable IP camera installation.
AZ Electrical provides networking, Wi-Fi and data cabling alongside CCTV installation where these systems need to work together.
What Is PoE CCTV?
PoE means Power over Ethernet.
A compatible IP camera can receive power and network connectivity through the same
Ethernet cable.
That can create a particularly clean architecture for professional CCTV systems.
A PoE setup may involve:
Cat5e/Cat6 cable
PoE network switch
NVR
Router/network connection
Cameras
The cameras themselves do not necessarily need separate electrical sockets at every position.
However, the cabling still has to be professionally routed back to the appropriate network or recording equipment.
What Should Be Included in a CCTV Installation Quote?
A useful CCTV quote should make it possible to understand what is actually being purchased.
Current Checkatrade London area pages identify common quote elements including a site survey, camera and recorder installation, app/software setup and basic user training.
When comparing proposals, look beyond the final figure and check:
Camera Quantity
How many cameras?
Exact Camera Specification
What manufacturer, model and resolution?
Lens and Field of View
What area is each camera expected to cover?
Night Performance
What happens when the light disappears?
Recorder
What NVR or DVR is supplied?
Storage
What hard drive capacity is included and approximately what retention is expected?
Cabling
Is cable installation included?
Will cables be concealed, clipped externally or placed in trunking?
Remote Viewing
Is phone/tablet setup included?
Network Equipment
Are switches, Wi-Fi equipment or other network components required?
Installation
Does the quote include all normal mounting and setup work?
Testing
Will every camera and recording function be demonstrated?
Handover
Will the customer know how to retrieve footage after an incident?
Warranty
What parts and workmanship warranties apply?
VAT
Is VAT included or excluded?
This last point matters particularly when comparing internet price guides because some published figures explicitly exclude VAT while others may not state the treatment prominently.
⬛ NEVER COMPARE TWO CCTV QUOTES BY THE TOTAL PRICE ALONE
Quote A:
£900
Quote B:
£1,250
At first glance, Quote A appears cheaper.
But imagine Quote A includes:
Four entry-level cameras
1TB recorder
Visible cable runs
No network improvements
Basic night-time performance
while Quote B includes:
Four higher-specification IP cameras
4TB storage
PoE network infrastructure
Concealed cable routes
Better low-light performance
Privacy masking
Remote-viewing setup
The two quotations are not competing descriptions of the same product.
Before comparing price, make sure you are comparing the same outcome.
Cheap CCTV vs Professionally Designed CCTV
There is an enormous range of camera equipment available online.
Which? currently reports that it has tested outdoor smart-security cameras costing below £50, but also warns consumers about security weaknesses it has previously found in cheap products sold through online marketplaces and recommends considering software-support periods and ongoing subscription requirements.
Low equipment cost is therefore not automatically the same thing as good value.
A security camera needs to do several things properly:
Remain reliable
Produce usable footage
Work at night
Store footage correctly
Be securely accessible
Remain supported
Cover the correct area
Avoid unnecessary privacy intrusion
A £40 camera that fails to capture useful evidence when something happens has delivered poor value regardless of its purchase price.
How Many CCTV Cameras Do I Actually Need?
The answer should be based on risk and coverage, not on the biggest package available.
A small terraced property might have three critical routes:
Front entrance
Rear access
Side passage
A detached property could have considerably more.
A commercial building may require:
Entrances
Exits
Stock areas
Loading bays
Car parks
Perimeter points
Reception areas
External yards
The cheapest system is often the one that uses the correct number of correctly positioned cameras, rather than adding cameras to compensate for poor design.
Does Every Camera Need to Be 4K?
No.
Different camera locations perform different jobs.
A camera monitoring a narrow front gate may not need the same specification as a camera expected to identify vehicles across a large yard.
A proper system can therefore use camera specifications according to purpose.
This is sometimes more cost-effective than using the highest specification everywhere.
Does CCTV Need Night Vision?
If the risk exists after dark, the system needs to produce usable images after dark.
That might involve:
Infrared illumination
Low-light camera technology
Existing security lighting
Additional lighting
What matters is not whether a specification sheet says "night vision".
What matters is what the recorded footage actually looks like at midnight under the lighting conditions present at the property.
Can CCTV Be Combined With an Intruder Alarm?
Yes.
CCTV and alarms perform different roles.
CCTV provides visual monitoring and recording.
Intruder alarms detect events such as unauthorised entry and raise an alert.
For many homes and businesses, combining multiple security layers can be more effective than trying to make cameras perform every function.
AZ Electrical also provides intruder alarm installation for residential and commercial properties.
What About Privacy and CCTV Law?
Camera placement is not purely a technical or pricing issue.
Domestic CCTV capturing identifiable people beyond the owner's property boundary can create additional data-protection responsibilities.
That means a professionally designed system should consider whether cameras unnecessarily record:
Neighbouring windows
Neighbouring gardens
Shared areas
Public space
Other private property
Privacy masking and better camera positioning can reduce unnecessary coverage.
This can be particularly important in London where properties sit close together.
Is DIY CCTV Cheaper?
At first, usually.
A homeowner buying cameras online and installing them personally avoids professional installation labour.
But whether DIY is genuinely better value depends on the system and the person's technical ability.
Potential problems include:
Poor camera angles
Unsafe work at height
Weak Wi-Fi
Poor cable routes
Incorrect storage configuration
Insecure passwords
Recorder problems
Inadequate night-time images
Blind spots
Inability to export footage
Unnecessary recording of neighbouring property
A simple smart camera may be realistic for a competent DIY user.
A multi-camera wired CCTV system covering several elevations is a very different project.
🟥 THE MOST EXPENSIVE CCTV PROBLEM CAN BE DISCOVERED AFTER THE INCIDENT
Imagine spending hundreds of pounds on cameras.
Six months later, someone approaches the property at night.
When you review the recording you discover:
The face is overexposed.
or:
The camera was pointed too high.
or:
The recorder had stopped storing footage.
or:
The timestamp was wrong.
or:
The camera had lost Wi-Fi connectivity.
The installation looked fine until the moment it was actually needed.
The real objective is therefore not to buy cameras.
It is to build a working evidence and monitoring system.
How Long Does CCTV Installation Take?
Checkatrade's national cost guide says a professional installation can typically take one to two days, depending on the number of cameras and the work involved.
Its current London area page says a small home installation can sometimes take only a few hours, while larger systems may take a full day or more.
Again, camera count is only one factor.
A three-camera system with difficult cable routes can take longer than a larger system in a building with straightforward infrastructure.
Commercial CCTV Installation Costs
Commercial CCTV is much harder to summarise with a single useful price.
A small office with four cameras could resemble a residential installation.
A warehouse might require:
Numerous high-resolution cameras
Long cable distances
Network cabinets
PoE switches
Fibre connections
Large storage arrays
PTZ cameras
Perimeter coverage
Access platforms
Out-of-hours installation
MyBuilder's broader 2026 security-camera guide places standard multi-camera installations within a wide range and emphasises that the monitored area, installation complexity, wiring and camera count all affect total cost.
For commercial premises, a site survey becomes particularly important because the cost should follow the operational and security requirement rather than a generic "camera package".
CCTV for Shops
Retail CCTV may need to cover:
Entrances
Till areas
Stock
Customer areas
Rear exits
Delivery points
Good positioning matters because a wide overview image does not automatically provide identification-level detail.
CCTV for Offices
Office systems may focus on:
Entrance and reception
External doors
Car parking
Sensitive areas
Out-of-hours access
Businesses also have greater data-protection responsibilities when recording employees, visitors and customers.
CCTV for Warehouses and Industrial Sites
This is where pricing can change dramatically.
Large sites may require:
Long-distance coverage
Multiple network switches
Fibre links
Large storage capacity
PTZ cameras
High mounting positions
Specialist access equipment
Perimeter lighting
Trying to price such a site using a "four cameras cost £X" formula is not meaningful.
What Costs Can Appear After Installation?
When budgeting, remember that the first invoice may not represent the entire lifetime cost.
Potential ongoing or future costs include:
Maintenance
Periodic checks and cleaning.
Hard Drives
Storage drives do not last forever and may eventually require replacement.
Cloud Subscriptions
Some smart-camera platforms require subscriptions for longer storage or additional
features.
Broadband or Networking
Network-dependent systems require reliable infrastructure.
Additional Cameras
Security requirements can change.
Upgrades
New cameras, recorders or network equipment may be added later.
Repairs
External cameras are exposed to weather and physical damage.
Designing the original system with sensible expansion capacity can sometimes reduce future upgrade costs.
Should I Choose Cloud CCTV or an NVR?
Neither answer is automatically correct.
An NVR May Suit You If:
You want local recording.
You have several IP cameras.
You want central storage.
You prefer not to rely entirely on cloud subscriptions.
Cloud Recording May Suit You If:
You want straightforward remote access.
You have only a small number of cameras.
Off-site footage is particularly valuable.
You are comfortable with ongoing subscription costs where applicable.
Some systems combine local and remote features.
The correct decision depends on the risk, internet connection, number of cameras and desired retention.
How to Reduce CCTV Installation Costs Without Buying the Wrong System
Reducing cost should be about removing waste rather than removing security.
Start With the Risk
Decide what actually needs protection.
Position Cameras Properly
One well-positioned camera can sometimes replace two badly positioned ones.
Use the Right Specification in the Right Place
Not every camera necessarily needs identical resolution or zoom capability.
Plan Cabling Early
Installing data cables during refurbishment can be easier than adding them after everything is decorated.
Think About Future Expansion
A recorder with spare capacity may make later expansion easier.
Avoid Features You Will Never Use
Buying every available smart feature does not automatically improve security.
Fix the Network
Do not compensate for bad Wi-Fi by repeatedly replacing perfectly adequate cameras.
⬛ THE CHEAPEST SYSTEM SHOULD NOT BE THE GOAL
The goal should be:
The least complicated system that reliably achieves the required security coverage.
That is different from:
The cheapest cameras available.
A properly designed system can sometimes save money because it avoids unnecessary cameras, excessive specifications and poor installations that later need replacing.
Questions to Ask Before Accepting a CCTV Quote
What exact cameras are being supplied?
Ask for manufacturer and model information.
What resolution will they record at?
Do not accept vague phrases such as "HD CCTV" without knowing the actual specification.
How many days of footage will be retained?
This depends on storage and recording settings.
Is recording continuous or motion activated?
That affects both storage and what footage is available.
What happens at night?
Ask how the proposed cameras perform under the actual lighting conditions.
Is remote viewing included?
Confirm whether phones and tablets will be configured.
Are subscriptions required?
Find out before installation.
Is cabling included?
And how will it be routed?
Is network equipment included?
Particularly important with IP CCTV.
Is VAT included?
Make sure every quote is being compared on the same basis.
What warranty applies?
Check both equipment and workmanship.
Can the system be expanded?
Useful if another camera may be required later.
How Much Should I Budget for CCTV in London?
Based on the independent data available in 2026, it is reasonable to expect a very wide market range.
Checkatrade's current London page gives an average of £872 for supply and installation, with a published range from £617 to £1,248.
Westminster's equivalent figure is £1,217 average, with its published range extending from £860 to £1,747.
MyBuilder places a standard four-camera system at £800–£1,100 and an eight-camera system at £1,000–£1,700.
That gives a useful budgeting framework.
But it should not be turned into a promise that your installation will fall within those numbers.
A system should be quoted after establishing:
What needs protecting.
How many cameras are genuinely required.
What image quality is needed.
How difficult the installation will be.
Where footage will be stored.
How the system will connect to the network.
🟥 GET A CCTV QUOTE BASED ON YOUR PROPERTY — NOT AN INTERNET AVERAGE
Online price guides are useful for understanding the market.
They cannot see your property.
They do not know:
Where your vulnerable areas are
How many cameras you need
Where cables can run
What happens at night
Whether your Wi-Fi reaches outside
How much footage you want to retain
Whether neighbouring property needs privacy masking
Whether you need home or commercial-grade equipment
AZ Electrical designs and installs CCTV systems for homes and businesses across London and surrounding areas.
The system can be planned around the actual property, including camera positioning, recording, remote viewing and supporting network infrastructure.
Frequently Asked Questions About CCTV Installation Costs
How Much Does CCTV Installation Cost in London?
Checkatrade's current London marketplace data lists CCTV installation at £733 average, with a published range of £520–£1,053.
Its supply-and-installation figure is £872 average, with a range of £617–£1,248.
These are third-party marketplace estimates, not AZ Electrical prices.
How Much Does a 4-Camera CCTV System Cost?
MyBuilder's January 2026 guide gives £800–£1,100 as a typical range for a standard four-camera system.
Checkatrade gives a starting figure of around £800 + VAT for a basic four-camera wired system supplied and installed.
How Much Does an 8-Camera CCTV System Cost?
MyBuilder gives approximately £1,000–£1,700 for a comprehensive eight-camera system.
Checkatrade gives a basic eight-camera wired system benchmark of around £1,000 + VAT including installation.
Why Is CCTV Installation More Expensive in Some Parts of London?
Property type, access, labour requirements, camera height, cable routes and system complexity all influence costs.
Current Checkatrade figures vary substantially between London locations such as Westminster, Ealing and Romford.
Is Wired CCTV More Expensive Than Wireless?
Installation can be more labour-intensive because wired CCTV requires physical cable routes.
Checkatrade's example guide currently gives £800 + VAT for a basic four-camera wired system versus approximately £450 + VAT for a four-camera wireless setup supplied and installed.
Is Wireless CCTV Completely Wireless?
Not necessarily.
Wireless normally refers to the data connection.
Many Wi-Fi cameras still require a power source unless they use rechargeable or replaceable batteries.
How Much Does CCTV Maintenance Cost?
Published marketplace guides currently give annual maintenance benchmarks of roughly £50–£100 or starting around £100 depending on the source and service involved.
Does CCTV Need a Monthly Subscription?
