Working in Purley

We cover every part of Purley, including CR2, CR5 and CR8, and nearby Coulsdon (1.7 miles) and South Croydon (1.9 miles).

London homes in Purley often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Whether your Purley 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 Purley home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Water across much of Greater London is very hard. 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
A floor sensor set between the heating runs and wired back to the thermostat
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

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.
