New electric showers and like-for-like replacements for Bath flats, houses and lets, on a circuit sized for the shower’s rating with its own RCBO and a proper isolator. Priced per job, with a fixed quote in writing.
Quick enquiry
Tell us the kW rating of the shower you have or want, if you know it. We come back within 24 hours.
An electric shower heats water as it runs, so it works whatever the boiler is doing and does not empty a hot water cylinder. In Bath that makes it a common choice in flats with limited hot water storage, in shared student houses where several people need a shower in the same morning, and as a second shower in an en-suite or loft conversion.
It is also one of the heaviest loads in the house. A shower circuit needs the right cable size for the kW rating and the length of the run, its own RCBO at the consumer unit, and an isolator in the bathroom. Getting any of these wrong is how showers end up tripping, scorching terminals or running lukewarm. We size the circuit properly, fit and test it, and notify the work under Part P.
From recent out-of-hours call-outs in rented homes: a shower in Larkhall tripping because its heating element had failed, a shower in Whiteway leaking from a broken valve inside the unit, and a shower pump in Twerton that had simply been disconnected. The pump was reconnected and left working; the two faulty units were isolated, made safe and flagged for replacement, as a priority where the tenant had no other way to wash.
| Job | Notes |
|---|---|
| Like-for-like swap | Same kW rating, existing circuit tested and confirmed suitable. |
| New 9.5kW installation | New 6 mm² circuit and RCBO on an existing suitable board. |
| New 10.5kW or 10.8kW installation | New 10 mm² circuit and RCBO. |
| Shower plus consumer unit | New circuit and a new RCBO board in one visit. |
We price each job on the shower's rating, the cable run and the state of the board, and confirm a fixed price in writing before we start. Shower units are priced separately by model. For a full bathroom refit, see bathroom electrics in Bath.
The price depends on the job. A like-for-like swap on a circuit that tests sound is the simplest; a new circuit, a 10.5kW or 10.8kW shower needing a heavier cable, or a new consumer unit alongside the shower all add to the work. We check the circuit and the board first, then give you a fixed written quote. The shower unit is extra and priced by model.
Only if the cable and protective device were sized for the higher rating. A 10.5kW shower draws over 40 amps, and many older Bath installations were wired for 7kW or 8.5kW units. We check the cable size, the length of the run and the protective device before quoting. If the circuit is too light, it is replaced, not overloaded.
It can be either. In recent Bath call-outs one tripping shower had a failed heating element inside the unit, and a leaking one had a broken valve inside the unit. Both units were made safe and flagged for replacement. We test the circuit as well, so you are not replacing a shower to fix a wiring fault, or the other way round.
We do the electrical side and arrange the plumbing through a plumber we work with, so you have one point of contact for the whole job.
Triton, Mira, Bristan, AKW and Aqualisa, among others. If you have a model in mind, tell us its kW rating when you enquire and we can check your circuit against it.
