Full service detail on our parent Fuse Board Upgrades page.
Castle Cary (BA7) is a small cathedral city with a strong base of independent schools, surgeries, dental practices and small commercial premises around the Market Place — alongside period stone cottages and Georgian townhouses. Many premises mix domestic and commercial circuits in one fuse board, and older stone walls need careful cable routing.
We're about 30 minutes from Castle Cary and cover BA7 as a core area — bookings are normally inside a week.

Yes. Period stone cottages around Castle Cary and Ansford often have old boards in awkward spots. We replace them with full-RCBO 18th Edition consumer units, route new meter tails neatly, and Part P notify the work via NAPIT.
A standard like-for-like RCBO consumer unit is typically a single-day job (8-10 hours including testing). 3-phase distribution boards or large 18-way domestic boards may run 1.5-2 days. We isolate at the cutout, work safely with the supply company's seal in place where required, and never leave a property without power overnight unless we've planned that with you.
BS 7671 18th Edition Amendment 2 (since 2022) recommends AFDDs (Arc Fault Detection Devices) on socket circuits in HMOs, care homes, and high-risk locations — not yet mandatory on all domestic, but recommended best practice. SPD (Surge Protection Device) on the incomer is now standard on all our new boards — it's the cheapest insurance against a single induced-surge event taking out every appliance in the house.
