Working in Braintree
We work right across Braintree — CM7 and CM77 — and in neighbouring Witham and Chelmsford.
Homes in and around Braintree vary, so we look at the floor, the walls and the water system before we price anything. For Braintree homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. Whether your Braintree bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Most of Essex 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- Bringing the system up to temperature gradually once the adhesive and grout have cured
Decisions to make first
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.
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.
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.
