Working in Romsey

As well as Romsey itself (SO51), we survey in Totton, Eastleigh and Southampton.

Romsey gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For Romsey homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. If your Romsey bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.

Supplies across most of Hampshire 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

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

Decisions to make first

Mat or loose cable

Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.

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.

Is the home survey in Romsey really free?

Do you cover SO51 in Romsey?

Yes. We cover all of Romsey, including SO51, and nearby Totton, Eastleigh and Southampton. Survey visits are free and arranged at a time that suits you.

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.
