Working in Beckenham

In Beckenham we cover BR3, SE20 and SE26; we also cover Catford, 2.5 miles away, and Croydon.

In Beckenham, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. Whether your Beckenham 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 Beckenham home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.

Most of Greater London has very 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 floor sensor set between the heating runs and wired back to the thermostat
A check of the floor construction, the room's heat loss and where the thermostat and supply will go
The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
Bringing the system up to temperature gradually once the adhesive and grout have cured

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.

Do you cover BR3 in Beckenham?

Yes. We cover all of Beckenham, including BR3, SE20 and SE26, and nearby Catford, Croydon and Blackheath. Survey visits are free and arranged at a time that suits you.

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.
