Help — electric shower tripping the electrics at a Swansea property

Owners often ask whether this can wait. Sometimes it can, and where electric shower tripping the electrics is the only finding we will say so plainly. Older installations around SA1–SA7 show this more often than newer ones.

If the property has been altered, extended or let out, electric shower tripping the electrics deserves more than a quick look. Sales-driven traders will quote a full board upgrade before they've even opened a socket. Every circuit affected is identified and labelled, which makes the next person's job — and yours — considerably easier. It rarely surprises us; it often surprises the previous quote.

Book same-day or next-day — don't keep resetting. On coastal terraces and detached homes in Mumbles and Sketty in particular, electric shower tripping the electrics tends to shape the plan more than the specification does. The materials rarely change; the route and the access do. We would rather rule out electric shower tripping the electrics early than discover it late. Electric shower tripping the electrics is easy to get quoted badly and hard to get quoted honestly without looking at the installation first.

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.

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.

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.

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.

Swansea context

We work to the current edition of BS 7671 and note where an older installation departs from it and why that matters. Most Swansea visits settle this within the first hour.

FAQs — electric shower tripping the electrics in Swansea

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.
