Do you need a new fuseboard?
It’s worth upgrading if any of these sound familiar:
- You still have rewireable fuses (the old wire-in-a-carrier type)
- Your consumer unit is plastic rather than metal
- There’s no RCD protection, or one RCD covering the whole house
- Fuses blow or breakers trip regularly
- You’re adding circuits for a kitchen, extension, loft or electric shower
- An EICR has flagged the board with a C2 or C3 code
What’s included
- New metal (non-combustible) consumer unit, as required by the current wiring regulations
- RCD or RCBO protection so a fault on one circuit doesn’t knock out the whole house
- Surge protection device (SPD) where required
- Main earthing and bonding checked and upgraded where needed
- Every circuit tested, labelled and logged
- Electrical Installation Certificate and building-control notification through NAPIT
How the day goes
Most fuseboard changes take between half a day and a full day. We test the existing circuits first so there are no surprises, the power is off while the new board goes in, and we leave everything working, labelled and tidied up.
Because we’re NAPIT registered, we can self-certify the work and notify building control for you — you’ll receive the certificate shortly afterwards.
“They sent someone over on the same day… checked to make sure that everything was working again. The efficient electrician who helped us was very polite and hardworking.”— Mohammed, Google review ★★★★★

Fuseboard questions
How much does a new consumer unit cost?
Our prices start from £550 supplied and fitted. The final price depends on the number of circuits, whether RCBOs are used and whether earthing or bonding needs upgrading — we confirm a fixed price before starting.
Why does it have to be metal?
The wiring regulations require consumer units in homes to be made of non-combustible material, which in practice means metal, to contain any fire caused by a fault.
What’s the difference between an RCD and an RCBO?
An RCD protects a group of circuits; an RCBO protects one circuit on its own. With RCBOs, a fault on one circuit won’t switch off the rest of the house.
Will the new board show up faults in my wiring?
Sometimes. Modern protection is more sensitive, so we test every circuit before swapping the board and tell you about anything we find first.
Do I get a certificate?
Yes — an Electrical Installation Certificate, and the job is notified to building control through NAPIT.
