Fuse box replacement means fitting a modern consumer unit with RCD or RCBO protection in place of an old fuse board. Our NICEIC registered electricians test your existing circuits first, so the new board suits the wiring you keep and anything you are planning, such as an EV charger, electric shower or garden room. Your written quote lists the board, the protection and any extra work, so you know the full price before the day. Replacement is notifiable under Part P, and as a registered contractor we handle the certificate and the building regulations notification for you.

Signs your fuse box needs replacing

  • Rewireable fuses with fuse wire instead of circuit breakers.
  • No RCD protection, or only some circuits protected.
  • An older plastic consumer unit under the stairs or in an escape route.
  • Scorch marks, a burning smell, buzzing or a hot enclosure.
  • An EICR with C2 observations about the board or its protection.
  • Plans for new circuits and no spare capacity on the board.

Scorching, buzzing or a burning smell need attention now rather than a planned upgrade: book an urgent consumer unit fault visit and we make the board safe first.

Split-load, high-integrity or full RCBO board

A split-load board shares two RCDs across the circuits, so one fault can switch off half the house. A high-integrity board adds circuits with individual RCBOs, and a full RCBO board gives every circuit its own protection, so a fault only switches off the circuit it is on. We recommend the type that suits your home and budget and explain the difference in the quote.

What happens to your existing circuits

Sound wiring stays in place. We test each circuit before and after the change, and any faults or earthing and bonding upgrades are listed separately in the quote so you can see exactly what you are paying for. Tell us about future plans and we size the board with spare ways for them.

Certificates you receive

At handover you get an Electrical Installation Certificate with the test schedules, plus the building regulations compliance certificate sent through our registration scheme. Keep them with your property documents; buyers and letting agents will ask for them.

Which consumer unit suits your home?

Most homes choose between a split-load board and a high-integrity or full RCBO board. The difference is how much of the house a single fault switches off.

  • Circuits tested first

    We test the wiring you are keeping before fitting the new board, so the protection suits the installation.

  • Power-off time agreed

    We plan around home working, fridges, alarms and essential equipment, and most homes are back on the same day.

  • Certified and notified

    Electrical Installation Certificate, test schedules and building regulations notification handled for you.

Which consumer unit suits your home?
Board typeHow it protectsTypical price
Split-load consumer unitTwo RCDs each cover a group of circuits; a fault trips the whole group.£460–£665
High-integrity boardTwo RCDs plus individual RCBOs for key circuits such as the freezer or alarm.£560–£895
Full RCBO boardEvery circuit has its own RCBO, so a fault only switches off that circuit.£560–£895

Our reading: A full RCBO board is the most convenient choice for most family homes; a split-load board suits smaller flats on a tighter budget. Your quote confirms the board, devices and any extra work.

How a fuse box replacement runs

  1. Send a photo and your postcode

    Share a photo of the closed fuse box, any recent EICR and your plans for new circuits. Leave the cover on; we do the checks.

  2. Survey and written quote

    We look at the board, earthing and circuits, recommend the right consumer unit and send a fixed written quote listing any extra work separately.

  3. Agree the day

    We book a date and agree the power-off window around home working, fridges, alarms and any essential equipment. Most replacements are completed in one day.

  4. Replace, label and test

    The new board is fitted, every circuit is tested and clearly labelled, and anything unexpected is priced for your approval before we continue.

  5. Handover and certificates

    We show you how the RCDs or RCBOs work and leave the Electrical Installation Certificate. The building regulations certificate follows through our scheme within 30 days.

Before replacement day

  • Book an urgent fault visit first if the board is hot, buzzing or smells of burning.
  • Keep the cover on; a photo of the closed board is all we need.
  • Tell us about essential equipment so we can plan the power-off window.
  • Expect the circuits you keep to be tested before and after the change.
  • Approve any extra work in writing before it starts.
  • Keep the EIC, test schedules and building regulations certificate together.

Fuse box replacement questions

How much does a fuse box replacement cost?

A split-load consumer unit typically costs £460–£665, and a high-integrity or full RCBO board £560–£895, including fitting, testing and certification. Your fixed price follows the survey; earthing upgrades or circuit faults found are quoted separately for approval.

How long does consumer unit replacement take?

Most domestic replacements are completed in one day, with the power off for most of that time. Extra circuits or remedial work can extend it, and we agree the timing and any arrangements for fridges, alarms or home working before the day.

Will I need a full rewire?

Usually not. Sound wiring is kept and tested. If the tests show a circuit needs work, we explain why and quote it separately, which may be a local repair rather than a rewire.

Is a consumer unit upgrade legally required?

There is no law that makes you replace a fuse box at a certain age. An upgrade is recommended when the board lacks RCD protection, shows damage or appears as a C2 on an EICR, and any replacement must be certified and notified.

Can I replace the consumer unit myself?

It is not a DIY job. It needs safe isolation, testing of every circuit and certification, and it is notifiable under Part P. A registered electrician self-certifies the work and handles the notification.

What certificates should I receive after replacement?

An Electrical Installation Certificate with the test schedules on the day, and a building regulations compliance certificate through the electrician's registration scheme. Keep both with your property documents.

Our electrics kept tripping and we had no idea why. He found the faulty socket and sorted it on the same visit. Really pleased, thanks again 👍
