Fault Finding & Repairs in London

Tripping circuits, flickering lights, dead sockets, humming boards. Proper fault finding on the tools — not trial-and-error replacement.

Everything covered under fault finding

Tripping RCDs & MCBs

We isolate the fault circuit, split the load, and test insulation to find the exact fault location without ripping up floors.

Dead Sockets / Lights

Loose terminations, burned conductors, broken neutrals. We find and fix them properly, not bodge them back together.

Flickering & Dimming

Loose neutrals at the board, undersized supply, damaged ring circuits. We diagnose and correct, often a simple fix.

Burned / Smelled Smells

Stop using the circuit and call. We test and replace any damaged components, verify the cause, and prevent repeats.

Common questions

How quickly can you get here?
Most faults we attend within the same or next working day. Emergency callouts available for safety-critical faults.
Do you charge if you cannot fix it?
No. If we diagnose a fault we cannot economically fix on the visit, we advise on options and only charge the diagnostic visit.
Can you diagnose without ripping up floors?
Usually yes — insulation testing, continuity, current flow and thermal imaging narrow the problem without invasive work.
Will the repair be certified?
Yes, any work we carry out is tested and certified on a minor works or full installation certificate as appropriate.
