Working in Oxford

We cover every part of Oxford, including OX1, OX2, OX3 and 1 more postcode districts, and nearby Aylesbury (19.4 miles) and High Wycombe (23.3 miles).

In a city the size of Oxford, parking and access for a skip are worth sorting before the start date — we will ask at the survey. Where a Oxford home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. Whether your Oxford bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.

Most of Oxfordshire 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

A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Bringing the system up to temperature gradually once the adhesive and grout have cured
A floor sensor set between the heating runs and wired back to the thermostat
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

Thermostat

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

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 Oxford: questions

What is the price of bathroom underfloor heating in Oxford?

Is the water hard in Oxford?

Who handles building control for bathroom underfloor heating in Oxford?

Building control for Oxford 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.
