Working in Cobham

We work right across Cobham — KT11 — and in neighbouring Esher and Weybridge.

Being a smaller town does not change how we work in Cobham: free survey, written quote, one team. Whether your Cobham bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. Where a Cobham home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.

Supplies across most of Surrey 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

Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
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
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed

Decisions to make first

Thermostat

A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.

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.

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.

More about underfloor heating

Underfloor heating in Cobham: questions

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

Bathroom underfloor heating in Cobham usually costs £800–£2,800 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose.

Who handles building control for bathroom underfloor heating in Cobham?

Building control for Cobham 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 Cobham.

Is the home survey in Cobham 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.

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.
