What moves the price
- Number of circuits — a larger home with more circuits needs a bigger consumer unit
- RCD or RCBO protection — individual RCBOs on each circuit cost more than shared RCDs
- Surge protection — a surge protection device is now commonly fitted with a new board
- Faults found — earthing or wiring faults uncovered during testing are fixed before sign-off of the consumer unit, adding cost
- Bonding — missing earth bonding to gas and water pipes adds work
- Location — moving the consumer unit to a new position adds cable and time
Electrical work prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical consumer unit / fuse board upgrade would have cost about £660 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Combine the consumer unit upgrade with an EICR or other electrical work in one visit
- Ask for a spare way or two so future circuits do not need another consumer unit
- Clear a path to the consumer unit and meter before the electrician arrives, so paid time goes on the upgrade itself
Before you book
- Consumer unit replacement is notifiable under Part P, so use a registered electrician such as NICEIC or NAPIT
- Ask what happens if faults are found in the existing wiring during testing
- Landlords need the electrics inspected regularly, and that inspection often prompts a fuse board upgrade
- Check you will receive an Electrical Installation Certificate and building control notification for the new consumer unit
Consumer Unit / Fuse Board Upgrade cost: questions people ask
£350–£750 per unit, about £525 typical. A small board with few circuits costs least; a larger RCBO board with faults to fix costs the most.
Four to eight hours, so expect the power to be off for most of the day.
Not always by law, but old boards lack RCD protection against electric shock. An EICR shows whether yours should be replaced.
Yes. It is notifiable work under Part P, and the electrician must issue a certificate and notify building control.
Repairs to faulty circuits, a rewire and moving the meter are separate. Ask whether surge protection is included.
