Working in Southall
As well as Southall itself (UB1, UB2, UB5 and 1 more postcode districts), we survey in Greenford, Heston and Hayes.
London homes in Southall often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. Whether your Southall 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 Southall bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.
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 dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- 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
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.
