Working in Acton

We cover every part of Acton, including W3, W4 and W5, and nearby Chiswick (1.4 miles) and Shepherds Bush (2.4 miles).

In Acton, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Acton bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. We check door thresholds in Acton homes at the survey, because underfloor heating and new tiles raise the floor slightly.

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
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded

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.

Mat or loose cable

Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.

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 I need an electrician to install bathroom underfloor heating?
