Faults & repairs

Professional fault‑finding for homes in Abergavenny & Forest of Dean and surrounding areas. Carried out calmly, methodically, and in full compliance with modern electrical standards.

Electrical faults rarely fix themselves. Whether it’s a tripping circuit, flickering lights, overheating accessories, or unexplained power loss, these issues point to a deeper problem that needs investigation. My fault‑finding service provides a structured, diagnostic led approach to identify the root cause and give you a clear, safe plan for repair.

What This Service Covers

Tripping circuits (RCBO / RCD trips)

Loss of power to sockets or lighting circuits

Overheating switches, sockets, or consumer unit components

Intermittent faults that come and go

Damaged wiring or accessories

Lighting faults (flickering, partial failure, buzzing)

Outdoor circuit faults (weather‑related trips, garden power issues)

Nuisance tripping after rain or damp conditions

Faults following DIY work or renovations

If something in your home is behaving unpredictably, this service is designed to find out why.

Electrical faults are often symptoms of deeper issues such as:

-Ageing wiring

-Overloaded circuits

-Water ingress

-Loose terminations

-DIY damage

-Deteriorated insulation

-Incorrect previous work

Left unresolved, these can lead to:

-Repeated power loss

-Overheating

-Electric shock risk

-Fire hazards

-Damage to appliances

A structured diagnostic visit ensures the problem is made safe and properly understood before any repair work begins.

Why does my RCD keep tripping?

RCD trips usually mean there’s earth leakage somewhere on the circuit. A common example is a neutral‑to‑earth fault inside an appliance, such as a washing machine or dishwasher. Even though the appliance is plugged into one socket, the leakage affects the entire RCD‑protected circuit, causing the RCD to trip. During a diagnostic visit, I isolate each circuit and appliance to identify exactly where the fault is coming from.

Can you find intermittent faults that only happen sometimes?

Yes. Intermittent faults are often caused by loose terminations, moisture, ageing wiring, or appliances that only leak to earth under certain conditions (heat, vibration, or load). Even if the fault isn’t happening at the moment, structured testing and isolation allow me to narrow down the source.

How long does fault finding take?

Most faults are diagnosed within the first hour, but this depends on access. Furniture, fitted units, stored items, and restricted areas can slow down the process if they prevent access to sockets, switches, or junction points. Some faults, especially those involving hidden wiring, multiple accessories, or water ingress. Can take 2–3 hours to fully trace. You’ll always get clear updates as the diagnostic progresses.

Do you need to turn the power off?

Yes. Safe isolation is essential. Power is only turned off for the affected circuit, and only for as long as needed to test safely.

What should I do if something is overheating or buzzing?

Switch off the circuit immediately and avoid using it. Overheating accessories or buzzing consumer units can indicate a serious fault and should be inspected as soon as possible.

Can you fix the fault on the same visit?

If the repair is straightforward and parts are available, yes. If the issue requires replacement components or more extensive work, I’ll provide a clear plan and cost before proceeding.

Do you work on rental properties?

Yes. I provide fault finding for landlords, letting agents, and tenants, including compliance‑led reporting where required.

What tests are used during electrical fault finding?

Typical diagnostic tests include:

Continuity testing
Insulation resistance
Polarity checks
Earth fault loop impedance
RCD/RCBO testing
Visual inspection of terminations, accessories, and wiring routes

These tests help pinpoint exactly where a fault is occurring and confirm whether the circuit is safe.

What’s the difference between an RCD trip and an MCB/RCBO trip?

RCD trips because of earth leakage or shock risk.
MCB/RCBO trips because of overload or short‑circuit.

Knowing which device is tripping helps identify whether the issue is caused by an appliance, wiring fault, or excessive load.
