Help — rcd keeps tripping at a Bridgend property

Bridgend sits inside the area we work daily, so a follow-up visit is not a logistical problem if one is needed. That is one reason our price does not move after the survey.

Here is how rcd keeps tripping works at a Bridgend address, including the parts that decide the price. We insulation-test to identify the leaking circuit, then trace to accessory or appliance. The point of a proper test is that the result is repeatable by anyone else with the same instrument. It is one reason we quote after the survey rather than over the phone.

RCD keeps tripping in Bridgend is almost always fixable on the first visit for a fixed price. Bridgend County Borough Council is the authority for Bridgend, so where the work is notifiable the registration goes through them. That is checked with instruments, not by eye. What matters for rcd keeps tripping is the condition of this installation, not the average condition of installations generally.

When to stop and call

If you can't isolate a single circuit or appliance and the RCD trips within seconds of reset, call — it's a wiring fault, not an appliance.

Likely causes

Cumulative earth leakage from multiple circuits sharing one 30mA RCD — each circuit is fine alone but together they exceed the threshold.
A faulty heating element (immersion, shower, oven, dishwasher) leaking to earth.
Moisture in an outdoor socket, security light or garden circuit.
A failed neutral-to-earth connection inside an appliance.

How we fix it

We insulation-test to identify the leaking circuit, then trace to accessory or appliance. Where the board is a shared-RCD split-load design at end-of-life, we quote an RCBO upgrade so each circuit has its own dedicated protection.

Typical price: £95–£180 diagnosis + repair. RCBO board upgrade £550–£950 depending on circuit count.

Safe checks you can do first

Turn every MCB under the RCD off, reset the RCD, then bring circuits back one at a time to find the offending one.
On the offending circuit, unplug appliances one at a time.
Note whether it trips more often in wet weather — a strong clue for outdoor water ingress.

Bridgend context

Owners often ask whether this can wait. Sometimes it can, and where RCD keeps tripping is the only finding we will say so plainly. That detail is what a proper survey is for.

FAQs — rcd keeps tripping in Bridgend

Should I upgrade to RCBOs?+

How long until you can attend?+
