Working in Winchester
We work right across Winchester — SO21, SO22 and SO23 — and in neighbouring Eastleigh and Romsey.
In a city the size of Winchester, parking and access for a skip are worth sorting before the start date — we will ask at the survey. Where a Winchester home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. We check door thresholds in Winchester homes at the survey, because underfloor heating and new tiles raise the floor slightly.
Water across much of Hampshire 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
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- 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.
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.
