Working in Wimbledon

We work right across Wimbledon — SW17, SW19 and SW20 — and in neighbouring Morden and Mitcham.

London homes in Wimbledon often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Whether your Wimbledon bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. If your Wimbledon home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Water across much of Greater London is 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

For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
A check of the floor construction, the room's heat loss and where the thermostat and supply will go
A floor sensor set between the heating runs and wired back to the thermostat

Decisions to make first

Floor heating and towel rail

Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.

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.

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.

Who handles building control for bathroom underfloor heating in Wimbledon?

Building control for Wimbledon is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does bathroom underfloor heating take?

Allow 1–2 working days (added to a fit) on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Wimbledon.

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.
