Working in Lancing
As well as Lancing itself (BN15), we survey in Shoreham-by-Sea, Worthing and Portslade.
Lancing gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Lancing home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. If your Lancing 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 West Sussex 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 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
Decisions to make first
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
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.
