Why immersion heater electrics in Bath is different

Bath is a UNESCO World Heritage city, most properties are Georgian or Victorian and many are Listed. Outdoor and bathroom electrical work here means careful coordination with conservation officers, minimal-intervention cable routes, and respect for original fabric (stone walls, lath-and-plaster ceilings, original cornice). We do a lot of work in central Bath terraces, hillside villas in Bathwick and Lansdown, and BA2 villages like Combe Down and Bathampton.

How we price immersion heater work in Bath

No two airing cupboards are the same, so we don't publish a price list. The price depends on what the job involves: a new radial and switched fused connection unit, Economy 7 timer and dual-element wiring, a fault-find on a tripping element, or a burnt switch replacement, along with access and the cable route back to the board. We look at the job first, by site survey or phone consultation, then give you a fixed written quote.

Common questions

Will you damage Listed fabric in a Bath property?

No. We use minimal-intervention routes, cables run under floorboards, in joist voids, behind existing skirting, or surface clip-direct on stone where chases would damage fabric. For Listed buildings we coordinate with the conservation officer or your architect before first-fix and document everything for the LBC.

Why does my immersion heater keep tripping the RCD?

Almost always a failed immersion element, when the Incoloy element corrodes, water leaks into the heating core and goes to earth. The RCD trips because there's a real earth fault. We test insulation resistance with a Megger, confirm element failure, isolate the supply and quote a replacement element with parts and labour.

Can I run my immersion on Economy 7 to save money?

Yes if you have an Economy 7 meter and the tank has two elements (or a single element you're happy to use overnight only). We wire two FCUs, one for the off-peak bottom element on the Economy 7 circuit, one for a 'boost' top element on standard tariff. A timer switches the off-peak circuit during the cheap-rate window.
