Working in Bangor

In Bangor we cover LL57 and LL59; we also cover Caernarfon, 8.3 miles away, and Llandudno.

Being a smaller town does not change how we work in Bangor: free survey, written quote, one team. Whether your Bangor bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. If your Bangor home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Water across much of Gwynedd is soft. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. 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
Bringing the system up to temperature gradually once the adhesive and grout have cured
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed

Decisions to make first

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.

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 Wales

In Wales, the Welsh Part P also makes a new underfloor heating circuit notifiable, and it covers more bathroom electrical work than the English version. A registered electrician handles the notification.

Underfloor heating in Bangor: questions

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

Bathroom underfloor heating in Bangor usually costs £650–£2,300 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose. After the free survey you get an itemised written quote, and the price is fixed in writing once the layout and products are agreed.

Do you cover LL57 and LL59 in Bangor?

Yes. We cover all of Bangor, including LL57 and LL59, and nearby Caernarfon, Llandudno and Colwyn Bay. Survey visits are free and arranged at a time that suits you.

Is the water hard in Bangor?

Who handles building control for bathroom underfloor heating in Bangor?

Building control for Bangor 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.
