What does a new consumer unit cost in Kingswood?
The written quote takes in the metal unit with RCD plus surge protection, the labour, a full test of each circuit and the certificate. Defects found on existing wiring, or an added circuit, are priced separately first.
How long is the power off during a board change?
It stays off for the bulk of the work. The visit runs from half a day up to a full day, with power restored once each circuit is tested on the new board.
Can old wiring go onto a modern board?
Where the wiring tests sound, yes. Each circuit is tested ahead of reconnection, and a fault that shows up is explained and priced on its own before any repair.
Do I get a certificate for a new fuse board?
Yes. A certificate is issued once the installation has been tested, and Part P notification is handled for you.
Is it worth replacing a board that still works?
A working board can still lack RCD protection, which is the part that protects people. If it has wire fuses or no RCDs, replacing it is the biggest safety improvement the property can make.
