Working in Shoreham-by-Sea
We work right across Shoreham-by-Sea — BN42 and BN43 — and in neighbouring Lancing and Portslade.
Being a smaller town does not change how we work in Shoreham-by-Sea: free survey, written quote, one team. Where a Shoreham-by-Sea home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Shoreham-by-Sea 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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
Decisions to make first
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.
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.
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.
