Working in Gloucester

We work right across Gloucester — GL1, GL2 and GL4 — and in neighbouring Cheltenham and Stroud.

In a city the size of Gloucester, parking and access for a skip are worth sorting before the start date — we will ask at the survey. We check door thresholds in Gloucester homes at the survey, because underfloor heating and new tiles raise the floor slightly. Where a Gloucester home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.

Most of Gloucestershire 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

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
For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
A check of the floor construction, the room's heat loss and where the thermostat and supply will go

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 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.

Underfloor heating in Gloucester: questions

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

Bathroom underfloor heating in Gloucester usually costs £700–£2,600 including VAT. Expect the lower end for a like-for-like job with standard products, and the upper end if things move or you choose premium finishes. Your quote is itemised and fixed in writing once agreed.

Is the water hard in Gloucester?

Who handles building control for bathroom underfloor heating in Gloucester?

Building control for Gloucester 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.
