Working in Keynsham

As well as Keynsham itself (BS31), we survey in Kingswood, Mangotsfield and Bishopsworth.

Being a smaller town does not change how we work in Keynsham: free survey, written quote, one team. For Keynsham homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. Whether your Keynsham bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.

Supplies across most of Somerset are 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

Bringing the system up to temperature gradually once the adhesive and grout have cured
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded

Decisions to make first

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.

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 Keynsham?

Building control for Keynsham 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.

Can underfloor heating go under vinyl or LVT?

Yes, with a compatible system and floor. Most vinyl and LVT makers set a maximum floor temperature, often lower than for tiles, so the thermostat's floor sensor is set to that limit. Tiles and stone remain the most efficient finish over underfloor heating.
