Working in Gravesend

In Gravesend we cover DA11 and DA12; we also cover Swanscombe, 2.6 miles away, and Grays.

In Gravesend, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Whether your Gravesend 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 Gravesend home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Most of Kent has very hard water. 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

Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
Bringing the system up to temperature gradually once the adhesive and grout have cured
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded

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 Gravesend?

Building control for Gravesend 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?

Is the home survey in Gravesend really free?

Yes. We visit, measure the room, check the pipework, drainage and electrics, and talk through what you want. You then get a written, itemised quote with no obligation to go ahead.

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.
