Working in Battersea

In Battersea we cover SW3, SW8 and SW11; we also cover Chelsea, 1.1 miles away, and Fulham.

In Battersea, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. For Battersea homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. We check door thresholds in Battersea homes at the survey, because underfloor heating and new tiles raise the floor slightly.

Supplies across most of Greater London are very hard. Hard water leaves white marks on dark grout and gloss tiles, so matt finishes and stain-resistant grout are the practical choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Bringing the system up to temperature gradually once the adhesive and grout have cured
A floor sensor set between the heating runs and wired back to the thermostat
A check of the floor construction, the room's heat loss and where the thermostat and supply will go

Decisions to make first

Insulation board thickness

Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.

Electric or wet

Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.

Rules that apply in England

In England, a new circuit for underfloor heating is notifiable under Part P, and so is connecting it to an existing circuit in a room with a bath or shower. The electrician either self-certifies through a competent person scheme or the work is notified to building control.

Do you cover SW3 in Battersea?

Yes. We cover all of Battersea, including SW3, SW8 and SW11, and nearby Chelsea, Fulham and Brixton. Survey visits are free and arranged at a time that suits you.

Is underfloor heating enough to heat a bathroom on its own?

In a well-insulated bathroom with most of the floor open, it often is. In a small room, the bath, WC and furniture cover much of the floor, so the heated area may be too small to be the only heat source. A heated towel rail alongside is the usual answer.
