Working in Morden

As well as Morden itself (SM4, SW19 and SW20), we survey in Mitcham, Wimbledon and Carshalton.

In Morden, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. For Morden homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. If your Morden bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.

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

A check of the floor construction, the room's heat loss and where the thermostat and supply will go
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 dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician

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.

Floor finish

Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.

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 Morden?

Building control for Morden 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 Morden.

Is electric underfloor heating expensive to run in a bathroom?

Running cost depends on the heated area, the insulation under the mat, how long it runs and your electricity tariff. As an example, a 150 W per m² mat covering 3 m² draws 450 W, so two hours a day uses about 0.9 kWh. A timer and floor sensor stop it running when nobody is using the room.
