Working in Derby

We cover every part of Derby, including DE1, DE21, DE22 and 2 more postcode districts, and nearby Belper (6.9 miles) and Ilkeston (7.7 miles).

Derby is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. For Derby homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. We check door thresholds in Derby homes at the survey, because underfloor heating and new tiles raise the floor slightly.

Water across much of Derbyshire is moderately hard. Mid-tone grout and matt tiles hide the odd water mark better than dark grout and high gloss. 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 check of the floor construction, the room's heat loss and where the thermostat and supply will go
A floor sensor set between the heating runs and wired back to the thermostat
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded

Decisions to make first

Insulation board thickness

Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.

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.

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 Derby: questions

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

Bathroom underfloor heating in Derby usually costs £650–£2,400 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose.

Do you cover DE1 in Derby?

Is the water hard in Derby?

Who handles building control for bathroom underfloor heating in Derby?

Building control for Derby 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 electric underfloor heating expensive to run in a bathroom?

Running cost depends on the heated area, the insulation under the mat, how long it runs and your electricity tariff. As an example, a 150 W per m² mat covering 3 m² draws 450 W, so two hours a day uses about 0.9 kWh. A timer and floor sensor stop it running when nobody is using the room.
