Working in Worthing
We work right across Worthing — BN11, BN12, BN13 and 1 more postcode districts — and in neighbouring Lancing and Shoreham-by-Sea.
Worthing has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. Whether your Worthing bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. If your Worthing bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.
Water across much of West Sussex is 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 floor sensor set between the heating runs and wired back to the thermostat
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- Bringing the system up to temperature gradually once the adhesive and grout have cured
Decisions to make first
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
