No power in one room — Merthyr Tydfil diagnostic visit

If you have had conflicting advice, it is usually because someone quoted without checking no power in one room. Two electricians looking at the same readings tend to agree. No power in one room is the part worth confirming rather than assuming.

Merthyr Tydfil property owners generally want to know two things about no power in one room: is it necessary, and what will it involve. Most callouts are closed on the first visit for a fixed price around £85–£150 for diagnosis and a single accessory replacement. Access is part of the job here. Merthyr Tydfil properties vary from open loft space to boarded conversions, and that changes how long a visit takes. It rarely changes the price, but it does change the plan.

We are NICEIC-registered, Part P notifiable, and every visit ends with a written certificate. Photographs of anything hidden are taken as standard, because you should not have to take our word for what is above the ceiling. We would say the same to a family member. People often put off no power in one room because they expect the worst. Usually the scope is narrower than feared.

Likely causes

A tripped MCB on the ring final circuit that hasn't been noticed — the label is often wrong or missing.
A loose neutral or line at a socket terminal — usually the last socket that was worked on.
A failed switched fused spur feeding a spur run for that room.
A cable damaged by a picture nail, screw or radiator bracket at the same height as buried cabling.

Safe checks you can do first

Check the consumer unit — is any breaker in the 'off' position?
Try a different appliance in the dead socket in case the appliance is the fault.
Check whether lights in the same room work — sockets and lighting are usually on separate circuits.

When to stop and call

If the breaker is up, sockets are fully dead, and there's no visible damage, call — the fault is inside the wiring.

How we fix it

We continuity-test the ring, identify the break point, and repair or replace the affected accessory. If a cable is damaged behind plaster, we agree the cheapest access route with you before opening anything up.

Typical price: £85–£150 for diagnosis and a single accessory replacement. Cable repairs behind plaster are quoted after inspection.

Do I need a rewire if one room has no power?+

Almost never. It's usually one loose terminal or one damaged accessory — 90% of these calls are fixed on the first visit.
