Rewiring & Electrical Fault Finding

Full and partial rewires done tidily in lived-in homes, and stubborn electrical faults tracked down and fixed.

A lot of West London housing stock still runs on wiring from decades ago — rubber or early PVC cables, no earth on the lighting circuits, sockets added ad-hoc over the years. If your home is due a rewire, we plan it around how you actually live: where you charge things, where the TV and router go, what the kitchen really needs.

We handle full rewires on empty and lived-in properties, and partial rewires where only part of the installation needs bringing up to standard — a new kitchen circuit, an extension, replacing a dangerous lighting circuit. Chases are cut cleanly, floors lifted and re-laid carefully, and every room is left usable at the end of each day wherever possible.

Got a nuisance trip, a dead circuit or a burning smell you can’t place? Fault finding is proper detective work and we’re good at it — we test methodically until we find the actual cause, rather than swapping parts and hoping.

How do you know if you need a rewire?

Warning signs include a fuse box with a wooden back or cast-iron switches, cables insulated in black rubber or fabric, two-core lighting circuits with no earth, sockets that are warm or discoloured, and regular tripping or flickering. An EICR gives a definitive answer — and if the wiring is sound, we’ll tell you that too.

Fault finding, the methodical way

Intermittent faults rarely show themselves on demand. We split circuits down, insulation-test each leg, and narrow the fault to a single point — a nicked cable under a floorboard, a cooked connection in a junction box, moisture in an outside light. You pay for a diagnosis and a fix, not for guesswork.

FAQs

Rewiring & Fault Finding — your questions

How long does a full rewire take?
A typical two-bed flat is around a week; a three-bed house usually one and a half to two weeks including making good. Partial rewires can be a day or two.
Can you rewire while we live in the house?
Yes — most of our rewires are in occupied homes. We work room by room, keep dust contained, and make sure you have power and lighting back every evening.
Why does my RCD keep tripping?
Common causes are a faulty appliance, moisture in an outdoor fitting or a deteriorating cable. Unplugging appliances one by one sometimes finds it; if the trip persists with everything unplugged, the fault is in the fixed wiring and needs testing — that’s where we come in.
