Who is this for?

Homeowners, tenants, landlords, and small businesses dealing with a tripping circuit, a dead socket, a faulty switch, or a light fitting that has packed up. Whole-house wiring investigations are outside our current scope, tell us what you have noticed and we will let you know straight away if it is the right fit.

Signs you need this

  • A circuit breaker or RCD keeps tripping without obvious cause
  • One or more sockets have stopped working or feel warm
  • A light fitting or switch has stopped working
  • You can hear buzzing or humming from a switch, socket, or consumer unit
  • An appliance keeps blowing fuses when plugged in

What is included

  • Systematic diagnosis at the fitting, switch, socket, or consumer unit
  • Identification of the root cause, not just the symptom
  • Repair on the same visit where parts allow
  • Replacement of damaged sockets, switches, or light fittings
  • Honest next steps if the fault sits deeper in the wiring than we can reach today

How it works

  1. 1Describe the problem to us over the phone or online. The more detail, the better.
  2. 2We visit and carry out a structured diagnosis, testing circuits and components methodically.
  3. 3Once we find the fault, we explain what is wrong and what it will cost to fix.
  4. 4We carry out the repair, test the circuit, and confirm everything is working safely.

Certification on Completion

All fault finding and repair work is carried out by NICEIC-registered electricians in line with BS 7671 (18th Edition Wiring Regulations).

I recently had four ceiling lights changed in my flat in Pinner, and I couldn’t be happier with the service. The work was completed at a very reasonable cost, and he was extremely kind, courteous and helpful throughout. As an elderly customer, I particularly appreciated his patience, professionalism and excellent customer care. He was reliable, respectful and made the whole process very easy. I would thoroughly recommend his services to anyone looking for a friendly, trustworthy and reasonably priced electrician.
