Working in Tunbridge Wells
In Tunbridge Wells we cover TN1, TN3 and TN4; we also cover Tonbridge, 4.3 miles away, and Crowborough.
In Tunbridge Wells, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. We check door thresholds in Tunbridge Wells homes at the survey, because underfloor heating and new tiles raise the floor slightly. Whether your Tunbridge Wells bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Water across much of Kent is 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- A floor sensor set between the heating runs and wired back to the thermostat
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.
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.
