FAQ
Common questions.
- Do I need to upgrade my fuse board?
- If yours is a plastic-cased or older wired-fuse board without RCD protection, an upgrade is strongly recommended for safety and insurance.
- How long is the power off?
- Usually 4–6 hours during the installation itself. We plan around your household.
- How much does a new consumer unit cost in Surrey?
- Most domestic consumer unit replacements in Surrey and South West London fall between £650 and £1,100 fitted, tested and certified. Larger boards, split supplies and rented properties needing remedials can sit above that.
- Is surge protection worth it?
- Yes on most modern homes. An SPD protects EV chargers, boilers, TVs and computers from supply spikes and adds around £120–£180 to the installation.
- Will you need to do remedial work first?
- Sometimes. A new board with RCBOs can reveal pre-existing faults such as borrowed neutrals or damaged insulation. We test before quoting so any remedials are priced up front, not sprung on you mid-job.
- Do I get a certificate?
- Yes. An Electrical Installation Certificate is issued on the day and the work is notified to Building Control under our NAPIT registration.
