Electrical fault finding and repairs in Balham
Tripping breakers, dead circuits and intermittent faults traced properly instead of guessed at.
From £85
first hour including full diagnosis, then £65/hour.
The classic Balham fault is a circuit that works perfectly except when it rains, and in the Heaver Estate houses it is nearly always the outside lighting or a garden supply installed during a side-return extension, where the cable was buried without proper protection. Insulation resistance testing in dry weather can read fine, so we test after rain or fit a logger. In Du Cane Court, flickering that affects several flats at once is a riser issue and not a flat-level fault at all.
The property types we see in Balham
The Heaver Estate — the grid between Nightingale Lane and Balham High Road — is 1890s to 1900s, and unusually for inner London a high proportion has stayed as single family houses rather than being converted. That means big installations: 12 to 16 circuits, loft conversions, side-returns and basement digs, each added at a different time and often by a different electrician. The Hyde Farm Estate to the south is smaller Edwardian workers' terraces, more often converted into flats. Du Cane Court is the outlier: 1930s, steel-framed, with shared risers, communal landlord supplies and a residents' management company whose consent is needed for anything touching common parts.
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

- 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

Getting to you in Balham
Balham is Wandsworth controlled parking and it is tight on the Heaver Estate grid, where the streets are narrow and residents-only for most of the day. We carry a trade permit. Du Cane Court has its own car park and porter, and jobs there need to be booked through the estate office — give us a few days' notice for anything beyond an emergency and we will arrange it.
