Working in Carterton
As well as Carterton itself (OX18), we survey in Witney, Oxford and Abingdon.
Carterton gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Whether your Carterton 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 Carterton 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 Oxfordshire has 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
- 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
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
Decisions to make first
Insulation board thickness
Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
