Working in Melksham

In Melksham we cover SN12; we also cover Trowbridge, 4.8 miles away, and Chippenham.

Melksham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For Melksham homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. Where a Melksham home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.

Most of Wiltshire has 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

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
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

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.

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 Melksham: questions

How much does bathroom underfloor heating cost in Melksham?

Bathroom underfloor heating in Melksham usually costs £700–£2,600 including VAT. Room size, layout changes and your choice of products move the figure within that range. The free survey gives you an itemised quote, fixed in writing once the details are agreed.

Who handles building control for bathroom underfloor heating in Melksham?

Building control for Melksham 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 Melksham.

Is the home survey in Melksham 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.

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.
