Working in Peacehaven
We work right across Peacehaven — BN10 — and in neighbouring Rottingdean and Seaford.
Peacehaven gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Peacehaven home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. Whether your Peacehaven 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 East Sussex 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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
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.
Floor heating and towel rail
Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.
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.
