Working in Banstead

As well as Banstead itself (KT17, SM2 and SM7), we survey in Sutton, Ewell and Epsom.

Homes in and around Banstead vary, so we look at the floor, the walls and the water system before we price anything. Whether your Banstead 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 Banstead bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.

Water across much of Surrey is 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

A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
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
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.

Do I need an electrician to install bathroom underfloor heating?
