Working in St Ives
As well as St Ives itself (PE27), we survey in Huntingdon, St Neots and Cambridge.
St Ives gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your St Ives home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. Whether your St Ives 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 Cambridgeshire are very 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- A floor sensor set between the heating runs and wired back to the thermostat
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
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.
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.
