Working in Christchurch
We work right across Christchurch — BH6, BH7 and BH23 — and in neighbouring Bournemouth and New Milton.
Homes in and around Christchurch vary, so we look at the floor, the walls and the water system before we price anything. If your Christchurch bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. Whether your Christchurch bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Supplies across most of Dorset are 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
Decisions to make first
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.
Electric or wet
Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.
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.
