Help — no power in one room at a Cardiff property

Nothing about this needs to be stressful — it is a known process with a known output. If the property is being sold or let, tell us the deadline and we will be honest about whether it is achievable.

People often put off no power in one room because they expect the worst. Usually the scope is narrower than feared. No power in one room is one of the most common calls we take from Cardiff — and one of the most misdiagnosed. Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. Which is why the price follows the test rather than the other way round.

We attend Cardiff calls from a base that reaches the A470 and A48 within minutes. What we are really assessing is condition, not age. No power in one room matters; the date on the board does not, by itself. The regulations are specific about it, so there is little room for opinion. No power in one room in a Cardiff property is not the same conversation as it would be in a new build, and it should not be priced as if it were.

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.

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.

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.

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.

Cardiff context

If the breaker is up, sockets are fully dead, and there's no visible damage, call — the fault is inside the wiring. Whether the property is owner-occupied or let in Cardiff, the technical work is identical — only the paperwork's recipient changes. Which is why the schedule of results is worth reading, not filing.

FAQs — no power in one room in Cardiff

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.

Will you need to lift floorboards?+

Only if the fault is under the floor. We locate the fault first, then agree access with you before opening anything.
