Electrical fault finding and repairs in Streatham
Tripping breakers, dead circuits and intermittent faults traced properly instead of guessed at.
From £85
first hour including full diagnosis, then £65/hour.
The dominant Streatham fault is the earthless lighting circuit showing itself as an RCD trip when a modern fitting or an LED driver is installed on it — the new fitting expects an earth the circuit has never had. It is quick to confirm and the fix is re-running that circuit through the loft. The other regular one is garden and outbuilding supplies: these houses have larger gardens than the rest of our patch and a lot of them have a shed or garden-office supply installed at some point without adequate protection, which trips in wet weather.
The property types we see in Streatham
The 1930s semis around Streatham Vale and Furzedown are the defining stock — bay-fronted, cavity-walled, with generous loft space and accessible floor voids, which makes them the easiest properties on our patch to work in. Their weakness is the vintage of their last upgrade: a great many were partially rewired in the 1970s or early 80s, which means PVC cable that is genuinely old, wall-mounted fuse boxes of that era, and lighting circuits with no earth. Telford Park is larger Edwardian housing, much of it still whole houses. Streatham Hill has interwar mansion blocks with communal risers and, in several cases, original 1930s intake positions still in service.
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 Streatham
Streatham is the furthest south we go and the response time reflects the run down the A23. Parking is markedly easier than the rest of the patch — much of SW16 is uncontrolled or lightly controlled, and most 1930s houses have a driveway, which makes van access simple and keeps costs down. The Streatham Hill mansion blocks need porter access for intake cupboards.
