Electric shower tripping the electrics — Bridgend diagnostic visit

Conditions locally play a part — exposure, damp and the way older post-war semis in Brackla and Wildmill were built all affect what we find. We would rather rule out electric shower tripping the electrics early than discover it late.

Searching "electric shower keeps tripping fuse" from a Bridgend address usually means you want a straight answer before you want a salesperson. Most callouts are closed on the first visit for a fixed price around £140–£220 for diagnosis + shower replacement. The practical question on this job is electric shower tripping the electrics, and it is answered by testing rather than by opinion. In Bridgend that usually decides both the scope and the sequence of the visit. Which is why the schedule of results is worth reading, not filing.

We are NICEIC-registered, Part P notifiable, and every visit ends with a written certificate. A written record matters as much as the work. Anything we find at a CF31–CF35 address is documented in a form you can hand to someone else. It takes minutes to confirm and saves hours later. Every electric shower tripping the electrics enquiry we take from Bridgend starts in the same place: what is the installation actually doing right now?

Likely causes

A failed heating element leaking to earth — the classic end-of-life shower fault at 6–8 years.
The shower cable undersized for the kW rating, overheating under load.
A shared RCD tripping when the shower's own tiny leakage adds to the rest of the circuits.
A corroded connection at the shower unit terminal block from years of steam.

Safe checks you can do first

Turn the shower off at its pull-cord and try running only cold — does the breaker still trip?
Check the shower's kW rating vs the cable size stamped on the sheath.
Note age of shower — 8+ years and it's often end-of-life regardless.

When to stop and call

If the breaker trips as soon as the shower is switched on, or if there's any smell of burning near the unit.

How we fix it

We insulation-test the shower circuit, confirm whether the fault is the appliance or the wiring, and either replace the shower unit (matching kW and cable) or upgrade the cable and RCBO to suit a higher-kW replacement.

Typical price: £140–£220 for diagnosis + shower replacement. Cable upsize quoted separately if needed.

FAQs — electric shower tripping the electrics in Bridgend

Can I just fit a stronger shower myself?+

No — a higher kW shower usually needs a bigger cable and matched RCBO. Fitting a 10.5kW on a 9.5kW cable is a fire risk.

How long does replacement take?+

A like-for-like shower swap is usually 90 minutes to 2 hours.
