Consumer Unit Replacement Cost London: Fuse Box Upgrade Price Guide
Consumer unit replacement in London typically costs somewhere within the hundreds of pounds, with current published market data placing many straightforward domestic installations around the £500–£750 range. Larger properties, higher-specification equipment and installations requiring additional remedial work can cost £1,000 or more.
There is no single correct price for replacing a fuse box or consumer unit.
A small London flat with six straightforward circuits is a completely different electrical job from a larger house containing twelve or more circuits, electric heating, an EV charger, solar equipment, a garden office and several generations of electrical alterations.
The type of consumer unit also matters. A modern board using individual RCBO protection, surge protection and additional capacity for future circuits will normally have a different equipment cost from a simpler arrangement.
The condition of the existing electrical installation can make an even bigger difference. Existing circuits need to be appropriately inspected and tested before they are connected to the new consumer unit. If electrical defects are discovered, those problems may need to be corrected before the installation can be safely completed.
The prices in this guide are independent UK and London market benchmarks. They are not AZ Electrical prices and should not be treated as an AZ Electrical quotation.
⬛ Consumer Unit Replacement Cost: The Quick Answer
Current published London pricing data suggests approximately:
£500–£750 for many typical consumer-unit replacement projects.
Broader UK market data places straightforward installations from roughly £350–£500 at the lower end, while larger or more complex residential installations can reach approximately £800–£1,200 or more.
A separate major UK consumer-price survey places a standard three-bedroom house at approximately £500–£1,500, depending on location, specification and work required.
London prices can sit towards the upper end of national ranges.
These figures should be used as a budgeting guide rather than a quotation.
The most useful question is not:
"What does a consumer unit cost?"
It is:
"What does the correct consumer unit replacement cost for this particular electrical installation?"
🟥 These Are Market Prices — Not AZ Electrical Prices
AZ Electrical does not publish one universal consumer-unit replacement price because electrical installations vary too much for that number to be meaningful.
A quotation should consider the number of circuits, consumer-unit specification, RCBO or RCD arrangement, surge protection, existing wiring, earthing and bonding, accessibility, electrical testing and any defects that need attention.
Two houses with the same number of bedrooms can require completely different amounts of electrical work.
Online averages are useful for establishing a sensible budget.
They cannot see the wiring inside your property.
What Is a Consumer Unit?
A consumer unit is the main electrical distribution point within a home.
Electricity enters the installation and is distributed from the consumer unit to individual circuits supplying areas such as lighting, socket outlets, cooking equipment, electric showers, heating, garages, outdoor electrics and other fixed equipment.
Many people still call it a fuse box, fuse board or simply the electrics box.
Older installations may contain rewireable fuses or cartridge fuses. More modern consumer units usually contain resettable protective devices such as circuit breakers, RCDs and RCBOs.
Modern equipment may also include surge protection and other protective technology depending on the electrical installation.
The consumer unit therefore does much more than simply provide somewhere to switch circuits on and off.
It contains important electrical safety devices designed to disconnect circuits when certain faults occur.
Fuse Box vs Consumer Unit: Is There Actually a Difference?
The terms are often used interchangeably by homeowners.
Technically, a traditional fuse box may contain physical fuses that need replacing or rewiring when they operate.
A modern consumer unit normally uses circuit breakers and residual-current protective devices that can usually be reset after the underlying fault has been addressed.
This is why people searching for:
fuse box replacement cost
and:
consumer unit replacement cost
are usually researching the same type of electrical upgrade.
However, replacing an older fuse box does not automatically mean the entire electrical installation needs upgrading.
The condition and safety of the existing circuits still need to be assessed individually.
Does an Old Fuse Box Automatically Need Replacing?
No.
An electrical installation should not be condemned simply because the consumer unit looks old.
Older fuse boxes can contain rewireable fuses, cartridge fuses or earlier types of circuit breaker that continue to provide appropriate overcurrent protection.
Likewise, an older plastic consumer unit does not automatically require replacement purely because modern boards are normally manufactured from non-combustible materials for relevant installations.
The important questions are:
What condition is the equipment in?
What protective measures are currently provided?
Are there signs of deterioration or overheating?
Does the existing arrangement provide suitable protection for the circuits?
Would upgrading materially improve electrical safety or allow required new circuits to be installed?
Age can be relevant.
Age alone is not the diagnosis.
How Much Does It Cost to Replace a Fuse Box in London?
For a straightforward London domestic installation, around £500–£750 is a useful current market benchmark.
However, published UK pricing ranges extend considerably beyond that.
Smaller six-circuit installations can sometimes sit closer to £350–£500, while larger homes with more circuits and higher-specification equipment can reach approximately £800–£1,200+.
A major UK consumer-pricing survey gives an even broader range of approximately £500–£1,500 for replacing the fuse box in a standard three-bedroom semi-detached home.
Why such a large difference?
Because the phrase "consumer unit replacement" tells you surprisingly little about the actual job.
Why Can Two Consumer Unit Quotes Be Hundreds of Pounds Apart?
Imagine two electricians both quote to replace the consumer unit in the same property.
One quotation provides a basic board with several circuits sharing residual-current protection.
The second provides individual RCBO protection across the circuits, surge protection, additional spare capacity and more extensive preparation.
Those are not necessarily equivalent installations.
The number of circuits also matters.
Six circuits require fewer protective devices than fourteen.
Existing electrical defects can change the job further. One installation may test perfectly satisfactorily. Another may reveal damaged wiring, inadequate bonding, poor insulation resistance or another condition requiring remedial work before a circuit can safely be reconnected.
This is why the cheapest quotation cannot automatically be assumed to be the best value.
Likewise, the highest quotation is not automatically the best installation.
Compare specification with specification.
🟥 Don't Compare Consumer Unit Quotes by Price Alone
Before comparing two quotations, check whether both include the same things.
Look for:
Consumer-unit manufacturer
Number of usable ways
RCBO or RCD arrangement
Surge protection
Electrical testing
Certification
Building Regulations notification
Circuit identification
Earthing and bonding work
Handling of existing electrical defects
VAT
Only then can you compare the totals properly.
A £550 quotation and an £850 quotation might not actually be quotations for the same job.
How Does the Number of Circuits Affect the Price?
The number of circuits is one of the most important pricing factors.
Every circuit requires appropriate protection within the consumer unit and needs to be inspected and tested as part of the work.
Current published price guides suggest smaller installations with around six circuits can begin within the lower hundreds of pounds.
A typical ten-way RCBO installation can sit around the middle of the market.
Properties containing twelve or more circuits generally move towards the higher end.
This is why bedroom count only tells part of the story.
A two-bedroom flat could contain dedicated circuits for electric heating, immersion heating, cooking, an electric shower and several other loads.
A larger house could potentially have a simpler installation.
Electricians are working with circuits, not bedrooms.
What Is an RCBO Consumer Unit?
An RCBO is a protective device that combines two important functions.
It provides protection against excessive electrical current associated with overloads and short circuits.
It also provides residual-current protection designed to reduce the risk associated with certain electrical leakage faults and electric shock.
Using individual RCBOs allows each circuit to have its own protective device.
This can improve circuit separation.
Imagine an electrical fault develops on an outdoor circuit.
With several circuits sharing one RCD, the fault could disconnect the outside electrics together with several healthy circuits.
With individual RCBO protection, the affected circuit can potentially disconnect independently.
That can mean less disruption and easier fault diagnosis.
RCD vs RCBO Consumer Units
A traditional dual-RCD arrangement normally places several circuits behind one RCD and another group behind a second RCD.
This can provide effective residual-current protection at a lower equipment cost.
The disadvantage is that one fault can disconnect several circuits simultaneously.
An RCBO-based board gives individual circuits their own residual-current protection.
For example, a fault on:
garden sockets
need not necessarily disconnect:
kitchen sockets, lighting and the freezer circuit.
Individual RCBO protection can therefore improve resilience and fault separation.
If your current electrical installation suffers from repeated trips, see:
What Is Surge Protection?
A surge-protection device, usually called an SPD, is designed to limit transient electrical overvoltages.
Modern homes contain increasing amounts of sensitive electronic equipment.
Examples include computers, televisions, broadband equipment, smart controls, appliances, CCTV, alarm systems, EV chargers and networking equipment.
A significant electrical surge can potentially damage this equipment.
Surge protection can therefore form an important part of a modern consumer-unit design.
When comparing quotations, check whether an SPD is included.
Do not assume every modern-looking consumer unit contains the same protective equipment.
What Are AFDDs?
AFDD stands for Arc Fault Detection Device.
These devices are designed to detect characteristics associated with certain dangerous electrical arc faults.
Their application depends on the installation, circuit type and current electrical requirements.
AFDDs can be considerably more expensive than ordinary breakers or RCBOs.
A quotation containing several AFDDs may therefore be significantly more expensive than a simpler consumer-unit installation.
This is another reason to compare the technical specification rather than simply asking:
"How much is the fuse box?"
Does the Existing Wiring Need Testing?
Yes.
A consumer unit replacement should not be treated as a purely mechanical job.
Existing circuits have to be appropriately assessed before being connected to the replacement equipment.
Testing can identify issues that were not obvious while the old consumer unit remained in place.
Possible problems include:
Poor insulation resistance
Damaged cables
Shared or borrowed neutrals
Earthing problems
Bonding problems
Incorrect circuit identification
Historic alterations
Inappropriate connections
A modern consumer unit cannot make those problems disappear.
It can sometimes expose them.
🟥 A Consumer Unit Replacement Is Not "Old Box Off, New Box On"
This point is worth emphasising.
Suppose an existing circuit contains damaged insulation.
The circuit may still appear to work.
Lights turn on.
Sockets provide electricity.
Nothing looks obviously wrong.
Replacing the consumer unit does not repair that cable.
Electrical testing associated with the upgrade may reveal the defect.
That circuit may then require further investigation or repair before it can be safely returned to service.
The new consumer unit did not necessarily cause the problem.
It helped reveal a problem that already existed.
What Happens if Electrical Faults Are Discovered?
That depends on the fault.
Some defects can be corrected relatively quickly.
Others require dedicated fault finding.
A transparent quotation should explain what happens if electrical defects are discovered during the work.
This is important because it is impossible to include every hypothetical hidden fault within one fixed consumer-unit price.
Otherwise, customers with good electrical installations would effectively pay for faults they do not have.
A sensible approach is:
Quote the known consumer-unit work clearly.
Then:
Explain how unexpected remedial work will be handled if testing finds a problem.
Does Replacing the Consumer Unit Mean I Need a
Rewire?
No.
This is another major misconception.
A consumer-unit upgrade does not automatically mean all existing electrical cables need replacing.
Existing wiring may have been installed under an earlier version of the Wiring Regulations and can still be suitable for continued service.
A rewire becomes relevant where inspection and testing identifies widespread deterioration, significant defects or other reasons replacement of the fixed wiring is appropriate.
One faulty circuit does not automatically mean the entire house needs rewiring.
Equally, installing a new consumer unit cannot transform badly deteriorated wiring into good wiring.
The actual condition of the installation should determine the answer.
Can I Replace the Fuse Box Without Rewiring My House?
In many properties, yes.
If the existing wiring tests satisfactorily and is appropriate for reconnection, the consumer unit can be replaced while most or all of the original circuits remain.
The electrician may still recommend improvements.
Certain circuits may need additional work.
Earthing or bonding might require attention.
But there is no universal rule that says:
new consumer unit = complete rewire.
If a full rewire is being recommended, ask what inspection and test results support that recommendation.
What About Earthing and Bonding?
Earthing and protective bonding are fundamental parts of electrical safety.
They need to be considered before a replacement consumer unit is connected.
A property could have a perfectly good consumer unit quotation but still require additional work if the existing earthing or bonding arrangements are inadequate.
This can sometimes add to the final cost.
Again, this is why the board itself is only one part of the job.
The consumer unit works as part of the whole electrical installation.
What About Meter Tails?
Meter tails are the heavy electrical conductors associated with the incoming supply, meter and consumer unit.
Their size, condition and arrangement need to be appropriate.
Depending on the installation, they may require alteration or upgrading.
Equipment associated with the electricity meter, service head or incoming network supply may also involve the energy supplier or distribution network rather than being equipment an electrician can freely modify.
If additional supply-side work is required, this can affect the timescale and overall project.
What if I Want to Move the Consumer Unit?
Relocating a consumer unit can be considerably more involved than replacing it in the same position.
Circuits may need to be extended.
Cable routes may need altering.
The relationship between the consumer unit, electricity meter and incoming supply can complicate matters further.
Published industry cost data suggests that moving a consumer unit can add several hundred pounds even in relatively straightforward circumstances.
Significant relocation of incoming electrical equipment can cost substantially more.
If the board is being moved, make sure the quotation clearly separates:
replacement
from:
relocation.
How Long Does Consumer Unit Replacement Take?
A straightforward domestic replacement commonly takes somewhere around half a day to a full working day.
Current published estimates place many ordinary replacements within roughly four to seven hours.
That can increase where:
There are many circuits
Circuit identification is poor
Access is difficult
Faults are discovered
Earthing or bonding requires work
The board is being relocated
Additional electrical work is included
Power will need to be disconnected during part of the installation.
That is worth considering if you work from home or rely heavily on electrical equipment.
Will My Electricity Be Turned Off?
Yes.
The electrical supply needs to be safely isolated while the old equipment is removed and the replacement consumer unit is installed and tested.
Before the appointment, consider:
Computers
Internet equipment
Refrigerators and freezers
Heating controls
Alarm systems
CCTV systems
Medical equipment
Home offices
If uninterrupted power is particularly important for any reason, discuss it before the work starts.
Is Consumer Unit Replacement Notifiable?
Yes, in England.
Replacing a consumer unit is notifiable electrical work under Part P of the Building Regulations.
An electrician registered through an appropriate Competent Person Scheme can normally self-certify qualifying work and arrange the Building Regulations notification.
Other Building Control routes exist where appropriate.
The important thing for the homeowner is to establish before the work begins how compliance and notification will be handled.
What Certificate Should I Receive?
A consumer-unit replacement involves significant electrical alteration and testing.
An Electrical Installation Certificate should normally be issued for the completed work.
For domestic work in England, the relevant Building Regulations compliance documentation should also be produced through the appropriate route.
Do not wait until after the installation to ask about paperwork.
Ask the electrician beforehand:
What electrical certificate will I receive?
Who handles the Building Regulations notification?
Is that included in the quotation?
Proper certification forms an important part of the completed installation.
🟥 The Paperwork Matters
You are not simply buying a metal enclosure containing switches.
You are buying electrical installation work.
That includes:
design
installation
inspection
testing
certification
and where applicable:
Building Regulations compliance.
Keep the resulting certificates with your property records.
They can be important later when selling, letting or carrying out further electrical work.
Do I Need an EICR Before the Consumer Unit Is Changed?
A completely separate full EICR is not automatically required before every consumer-unit replacement.
However, adequate inspection and testing of the existing electrical installation is essential.
Where little is known about the electrical installation, or there are concerns about its wider condition, a full Electrical Installation Condition Report may be sensible before major work proceeds.
The two documents perform different functions.
An EICR reports on the condition of an existing electrical installation.
An Electrical Installation Certificate certifies new electrical work or alterations.
If you already have an EICR containing observations you do not understand, see:
Does a Plastic Consumer Unit Need Replacing?
Not automatically.
Modern domestic consumer units normally use non-combustible enclosures where current requirements apply.
That does not retrospectively make every existing plastic consumer unit dangerous.
The condition of the installation matters.
A plastic enclosure showing serious heat damage, deterioration or unsafe alterations is a different issue from an older board that remains in suitable condition.
The correct question is therefore not:
"Is it plastic?"
It is:
"Is this consumer unit and the installation it protects safe and appropriate for continued use?"
Does an Old Fuse Box Have to Be Replaced?
Again, not purely because of age.
Older fuse boxes can lack protective features commonly found in modern installations.
For example, they may provide less residual-current protection or poorer circuit separation.
Upgrading can therefore offer meaningful benefits.
But the decision should be made from the condition and needs of the electrical installation rather than from the date printed on the equipment.
When Is Consumer Unit Replacement Worth Considering?
An upgrade can be worth considering where the existing board is damaged, deteriorated or no longer suitable for the electrical installation.
It may also be appropriate where major electrical work is being carried out and the existing board cannot appropriately accommodate new circuits.
Other reasons can include improving protective arrangements or preparing the property for future electrical technology.
Potential future additions include:
EV charging
Solar PV
Battery storage
Heat pumps
Electric heating
Garden offices
Extensions
Air conditioning
Additional outdoor circuits
The new consumer unit should be designed around both current needs and realistic future requirements.
Consumer Unit Replacement During Renovation
A renovation can be one of the best times to review the electrical distribution system.
Suppose the project includes:
a new kitchen, extension, loft conversion, outdoor lighting, garden office and EV charger.
Designing those circuits around an old consumer unit with no spare capacity may create unnecessary complications.
Planning the distribution system early allows the electrician to consider the completed property rather than repeatedly adapting the installation as each new requirement appears.
This can also reduce disruption later.
EV Chargers and Consumer Units
An EV charger creates a substantial new electrical load and normally requires its own dedicated electrical design.
Whether the existing consumer unit can accommodate it depends on the installation.
Sometimes sufficient capacity already exists.
Sometimes additional distribution equipment can be used.
Sometimes replacing or expanding the consumer unit makes more sense.
There is no universal rule saying an EV charger automatically requires a new fuse box.
The electrical installation needs to be assessed.
Solar Panels and Home Batteries
Solar PV and battery storage can also change the electrical requirements of a property.
If you expect to install these technologies, mention them before the new consumer unit is selected.
Likewise, if the property may later receive a heat pump, electric heating or other significant load, that future requirement should be considered.
A consumer unit is not something most homeowners want to replace repeatedly.
Allowing sensible future capacity can therefore be valuable.
🟥 Future-Proofing Does Not Mean Buying the Biggest Board Available
Future-proofing should be realistic.
There is little benefit in installing unnecessary equipment simply because more sounds better.
But there can be significant benefit in avoiding a consumer unit with no spare capacity when you already know an EV charger or garden office is likely to be added next year.
Good electrical design balances:
current requirement
with:
credible future demand.
Why Can London Consumer Unit Costs Be Higher?
London has an extremely varied property stock.
A consumer-unit replacement could take place in:
A modern apartment
A Victorian terrace
A converted house
A basement flat
A large detached home
A commercial unit
A heavily extended property
Older London homes may contain several generations of electrical work.
Converted properties can have unusual distribution arrangements.
Access and parking can also affect the practicalities of working at some locations.
Published electrician-cost data generally places London and the South East towards the upper end of UK labour ranges.
But location alone should not be used to justify an unexplained price.
A good quotation should still show what is being supplied.
Consumer Unit Replacement for Landlords
Landlords should not assume an old fuse box automatically means their EICR will be unsatisfactory.
EICR classification is based on the actual electrical condition and safety risk.
Where C1 or C2 observations are recorded, those defects require appropriate attention.
A C3 has a different meaning and represents an improvement recommendation.
If replacing the consumer unit forms part of landlord remedial work, keep the resulting electrical certification with the original EICR and other electrical records for the property.
For more detail, see:
Can Replacing the Consumer Unit Stop RCD Tripping?
Sometimes, but only when the existing protective arrangement contributes to the problem.
Imagine an outside light has a water-ingress fault.
Replacing the consumer unit does not repair the light.
If a washing machine has an insulation fault, a new RCBO cannot repair the washing machine.
If a cable has been damaged by a screw, the cable still needs repairing.
A modern consumer unit can improve circuit separation and protective arrangements, but the underlying electrical fault still needs to be identified.
See:
⬛ Seven Questions to Ask Before Accepting a Consumer Unit Quote
1. What make and model of consumer unit are you installing?
2. Will the circuits have individual RCBO protection or shared RCD protection?
3. Is surge protection included?
4. What electrical testing is included?
5. What happens if an existing circuit has a fault?
6. Will I receive an Electrical Installation Certificate and Building Regulations
compliance documentation?
7. Is VAT included in the final quotation?
Those seven answers make it much easier to compare quotations fairly.
Is the Cheapest Consumer Unit Quote a Bad Choice?
Not necessarily.
A competent electrician may offer competitive pricing because the installation is straightforward or because their operating costs and supplier arrangements are efficient.
Likewise, the most expensive quotation does not automatically guarantee the best electrical installation.
The question is whether the quote provides appropriate:
equipment
protection
testing
certification
compliance
and:
clarity.
A suspiciously low quotation becomes a concern when nobody can clearly explain what is included.

Frequently Asked Questions About Consumer Unit Replacement Cost
How Much Does Consumer Unit Replacement Cost in London?
Current published London market data places many typical installations at approximately £500–£750.
Larger or higher-specification installations can cost £1,000 or more depending on circuit count, protective equipment, existing wiring and remedial requirements.
How Much Does a New Fuse Box Cost for a 3-Bedroom House?
Published UK data gives a broad range of approximately £500–£1,500 for a standard three-bedroom house.
London can sit towards the higher end of national labour rates.
Can Consumer Unit Replacement Cost More Than £1,000?
Yes.
Larger installations, additional RCBOs, specialist protection, more circuits and remedial electrical work can all push the total above £1,000.
Why Are Consumer Unit Quotes So Different?
The quotes may contain completely different board specifications, numbers of protective devices, testing requirements, certification arrangements and remedial allowances.
Does the Price Include Electrical Testing?
It should include the inspection and testing required for the installation work.
Always confirm exactly what testing and certification the quotation includes.
Do I Need an EICR Before Changing My Consumer Unit?
Not necessarily as a separate complete report, but appropriate inspection and testing of the existing installation is essential.
A full EICR can be useful where the wider condition of the electrical installation is unknown.
Does Replacing the Fuse Box Mean I Need a Rewire?
No.
Existing wiring can potentially remain where inspection and testing shows that it is suitable.
A rewire should be recommended because of the condition of the wiring, not simply because a new consumer unit is being installed.
Does a Plastic Consumer Unit Have to Be Replaced?
Not solely because it is plastic.
Its overall condition, protective arrangements and installation circumstances should be assessed.
Does an Old Fuse Box Have to Be Replaced?
Not purely because of age.
Older protective equipment can remain serviceable, although upgrading may provide additional protection and useful modern features.
Is Consumer Unit Replacement Notifiable?
Yes. Replacement of a consumer unit is notifiable electrical work under Part P in England.
What Certificate Should I Receive?
An Electrical Installation Certificate should normally be issued following the completed replacement and testing.
Appropriate Building Regulations compliance documentation should also be provided through the relevant route.
What Is an RCBO?
An RCBO combines residual-current protection and overcurrent protection for one circuit.
Are RCBO Consumer Units Better?
Individual RCBO protection can provide better circuit separation and reduce the number of unrelated circuits affected when one fault occurs.
The correct design still depends on the installation.
What Is an SPD?
An SPD is a surge-protection device designed to limit certain temporary electrical overvoltages.
Does Every Consumer Unit Include Surge Protection?
Do not assume it does.
Check the quotation and consumer-unit specification.
How Long Does Consumer Unit Replacement Take?
Many straightforward residential replacements can be completed within approximately half a day to one working day.
Complex installations or electrical faults can increase the duration.
Will My Electricity Be Off During the Work?
Yes.
The electrical supply needs to be safely isolated during parts of the replacement and testing process.
Can a New Consumer Unit Stop My RCD From Tripping?
Only where the issue relates to the existing protective arrangement.
A new consumer unit will not repair an underlying appliance or wiring fault.
Should I Allow Spare Capacity?
Often yes, particularly if an EV charger, solar PV, battery system, extension, garden office or other electrical work is likely in the future.
Can Landlords Replace the Consumer Unit Instead of Getting an EICR?
No.
The two serve different purposes.
An EICR reports on the condition of an existing installation. A consumer-unit replacement is electrical installation work.
Are These AZ Electrical Prices?
No.
All pricing figures within this guide are independent market benchmarks.
An AZ Electrical quotation would be based on the actual property and electrical installation.
