Replace your old fuse board
We replace consumer units from £650.00, with 93% of installations completed within one day.
Your fuse box sends power to the lights, sockets and appliances around your home, and a modern replacement can add individual circuit protection without replacing wiring that is still safe to use.
Our NICEIC-registered electricians have over 20 years’ electrical experience and check your existing circuits before recommending a new board, so you know what needs changing and what can stay. We explain the protection included, any repairs needed and when the power will be off.
Before you book, we explain the replacement price and expected power-off time.

What affects consumer unit replacement cost
The number of circuits, protection selected and condition of your wiring affect the price, along with any changes needed to the board’s position or access.
Circuit count
Each extra circuit adds £100.00 to your replacement.
Wiring condition
Wiring faults need repairing before we fit your new board.
Surge protection
Adding appliance surge protection costs an extra £100.00.
Board relocation
Moving your board adds £150.00 for extra cable work.
New fuse board or full rewire?
A new consumer unit from £650.00 can improve circuit protection without a full rewire, provided the existing wiring passes the checks needed for reconnection.
We check circuits, earthing and bonding before recommending the work. Damaged wiring may need repair or replacement, while sound circuits can stay. A new board does not fix faults elsewhere in the wiring, so we explain those findings before you commit.

Signs you may need a new fuse board
Repeated electrical faults, damaged covers and missing circuit protection warrant a professional assessment; the age of your fuse board alone cannot establish whether replacement is needed.
Old wire fuses
Have the protection checked before planning an upgrade.
No RCD protection
Ask whether your circuits need additional shock protection.
Repeated tripping
Find the cause before assuming the board needs replacing.
Burn marks
Keep away from damaged equipment and call for help.
New circuits
Check available space before adding new electrical circuits.
Damp or corrosion
Keep away and have the affected equipment checked.
Mixed components
Have mixed protective devices checked for safe use.
Damaged covers
Missing covers or blanks can expose dangerous parts.
Poor access
A difficult position may need changing during an upgrade.
EICR findings
Use the report to discuss which improvements are needed.

New parts
New parts can take 1–3 working days to arrive for fitting.
Board move
Moving your board adds 1–2 days for rewiring and testing.

6-circuit replacement
From £650.00
allow 1 day.
A compact replacement for up to six agreed existing circuits. Includes a metal board, suitable protective devices, circuit labels, fitting, testing and the Electrical Installation Certificate.
Existing circuits must be suitable to reconnect. We explain the chosen protection and any separate repairs in your written quote.
- Discuss your replacement quote
8-circuit replacement
From £750.00
allow 1 day.
A replacement for up to eight agreed circuits, such as separate lighting, socket, cooker and shower circuits.
Includes the agreed protection, fitting, labels, testing and certificate. Circuit count is a guide; the existing wiring and the devices selected determine the final quote.
- Discuss your replacement quote
10-circuit replacement
From £850.00
allow 1 day.
For installations with up to ten agreed circuits.
Includes the agreed metal consumer unit, protective devices, installation and certification. More circuits mean more connections and tests, and the quote identifies any repairs needed before reconnection rather than treating them as automatically included.
- Discuss your replacement quote
12-circuit replacement
From £950.00
allow 1 day.
For up to twelve agreed circuits, with the chosen protective devices, fitting and testing included.
We consider spare ways for future work, but extra capacity in the board does not itself increase your electricity supply. New circuits, supply changes and wiring repairs are priced separately where needed.
- Discuss your replacement quote
RCBO protection
From £750.00
allow 1 day.
An eight-circuit example with individual RCBO protection, fitting, testing and certification.
Each RCBO protects its circuit against residual-current faults and overcurrent, helping limit the circuits affected by a trip. We fit compatible devices and show you which circuits each switch protects.
- Discuss your replacement quote
Surge protection
From £650.00
allow 1 day.
A six-circuit example with the agreed surge protection included.
The device helps protect connected equipment from transient overvoltages and is separate from shock and overcurrent protection. We explain its specification and any existing-installation work needed; this is not an additional surcharge on every base price.
- Discuss your replacement quote
Board relocation
From £1,150.00
allow 1–2 days.
Moving the board can require longer cables, a different mounting position and extra work around the meter and supply arrangements.
This example includes fitting and testing the replacement board. We check accessibility, cable routes and isolation before confirming the price; wall or cupboard repairs may be separate.
- Discuss your replacement quote
Wiring repairs
From £120.00
allow as agreed.
An example starting allowance for an accessible repair found during the home visit.
The work depends on the fault, affected circuit and access, so we explain the repair and agree its price before starting. This is separate from the board replacement and is not a fixed fee added to every installation.

Consumer unit FAQs
Find answers about replacement costs, power cuts, existing wiring and circuit protection, including what the visit involves and the certificate you receive when work is complete.
How much does consumer unit replacement cost?
Our starting price is £650.00 for a straightforward six-circuit replacement, including the agreed board, fitting, testing and Electrical Installation Certificate. Circuit count, protection and any wiring repairs affect the total, so we check the installation and explain your quote before you book.
- Want a quote for your board?
How long does consumer unit replacement take?
Allow one day for a straightforward replacement, with the electricity switched off during removal, fitting and testing. We explain the expected power-off time beforehand. Plan around internet equipment, heating controls and medical equipment; extra wiring repairs or access work can extend the visit.
- Plan your installation day
Can you fit a new consumer unit to old wiring?
Yes, if the existing circuits are suitable to reconnect. We check the wiring, earthing and bonding and explain any repairs needed before fitting the new board. Older wiring does not automatically mean a full rewire, but replacing the board does not repair damaged cables or unsafe connections.
- Discuss your existing wiring
What is the difference between an RCD and an RCBO?
An RCD detects current leaking from its intended path and disconnects the circuits it protects. An RCBO combines that protection with overload and short-circuit protection for one circuit. Individual RCBOs can limit a fault-related outage to that circuit, rather than switching off a group of circuits.
- Compare protection options
Does a new fuse board need surge protection?
We assess the installation and explain the surge protection included in your quote. A surge protection device helps limit transient overvoltages that can damage connected equipment; it does a different job from an RCD or RCBO. The chosen board and devices must be suitable for your installation.
- Ask what your quote includes
Will I get an electrical certificate?
Yes. Consumer unit replacement is recorded on an Electrical Installation Certificate with the relevant inspection and test results. Keep it with your property records. An EICR reports on the condition of an existing installation; it is a different document and is not a substitute for the installation certificate.
- Ask about your paperwork
Does a plastic fuse board have to be replaced?
Not solely because it is plastic or an older design. We assess its condition, protection and suitability for continued use, alongside any inspection findings. A new installation must meet the applicable requirements, but an existing board is not automatically unsafe simply because standards have changed.
