Working in Hayes

We work right across Hayes — UB3, UB4 and UB11 — and in neighbouring Southall and Heston.

In Hayes, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. Whether your Hayes 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 Hayes home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

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

Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
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

Floor finish

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

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.

Underfloor heating in Hayes: questions

How much should I budget for bathroom underfloor heating in Hayes?

Is the water hard in Hayes?

Who handles building control for bathroom underfloor heating in Hayes?

Building control for Hayes 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.

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.
