Working in South Croydon
We cover every part of South Croydon, including CR0, CR2 and CR9, and nearby Croydon (1.5 miles) and Purley (1.9 miles).
London homes in South Croydon often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Where a South Croydon home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your South Croydon home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
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 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- 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.
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.
