Working in Greenwich

We work right across Greenwich — SE3, SE7, SE10 and 1 more postcode districts — and in neighbouring Blackheath and Canary Wharf.

London homes in Greenwich often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For Greenwich homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. Where a Greenwich 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

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
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
A floor sensor set between the heating runs and wired back to the thermostat

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.

Thermostat

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

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 Greenwich: questions

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

Is the water hard in Greenwich?

Who handles building control for bathroom underfloor heating in Greenwich?

Building control for Greenwich 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 Greenwich.

Is underfloor heating enough to heat a bathroom on its own?

In a well-insulated bathroom with most of the floor open, it often is. In a small room, the bath, WC and furniture cover much of the floor, so the heated area may be too small to be the only heat source. A heated towel rail alongside is the usual answer.
