Electrical fault finding and repairs in Wandsworth
Tripping breakers, dead circuits and intermittent faults traced properly instead of guessed at.
From £85
first hour including full diagnosis, then £65/hour.
In Earlsfield's converted flats, the recurring fault is the borrowed-neutral problem — one flat's RCD tripping because of another flat's appliance. In the Tonsleys, damp is the dominant cause: solid walls with no cavity and no damp course mean ground-floor socket circuits sit in genuinely wet masonry, and insulation resistance falls seasonally. That is not a fault you fix by replacing an accessory; it needs the circuit rerouting above the damp line, and we will explain why rather than just swapping sockets.
The property types we see in Wandsworth
The Tonsleys are 1850s–1870s two-up two-down cottages, small, solid-walled and with almost no floor void — which makes every cable run a chase. Southfields is the 1900s grid between the common and the district line, larger and mostly still whole houses. Earlsfield is smaller Victorian terrace, heavily converted to flats. The riverside developments — Ram Quarter, Wandsworth Riverside Quarter — are new-build with three-phase supplies, heat networks and, importantly for us, sprinkler and alarm interfaces that mean electrical work often has to be coordinated with the building's fire strategy.
What fault finding involves
Most tripping-breaker faults are found within the first hour, and that first hour costs £85. We trace faults with insulation resistance and loop testing rather than swapping parts until it stops — which is how people end up paying for a new consumer unit they never needed.
You need us if
- An RCD or breaker that trips repeatedly, or only at certain times
- A dead socket, circuit or lighting ring
- Lights that flicker or dim when an appliance starts
- A circuit that only trips when it rains, or overnight
- Warm switches, sockets or a warm consumer unit
- Another electrician has already 'fixed' it and it came back
What's included
- Systematic testing — insulation resistance, continuity, earth loop impedance
- Intermittent and weather-related faults chased properly, not guessed
- The cause explained and shown to you, not just described
- Most repairs completed on the same visit from van stock
- A fixed price for the repair before we do it
- Minor Works Certificate covering everything altered
The standard we work to
Diagnosed and repaired to BS 7671 (18th Edition), with test results recorded on a Minor Works Certificate.
Getting to you in Wandsworth
Wandsworth is our furthest patch and the response time reflects the traffic on Trinity Road and the one-way system rather than the mileage. Old York Road and the Tonsleys have very limited parking and narrow streets. The riverside blocks all require concierge sign-in and most require a permit to work for anything beyond a basic repair, which we handle but which needs a day's notice.
