Underfloor Heating Installation in Swansea – No-Obligation Quotes from Experienced Installers
Planning underfloor heating for a new extension in Swansea? Our network can connect you with installers covering Swansea who design and fit wet and electric underfloor heating, from a single bathroom mat to a whole ground floor. Each installer will work out how much heat each room needs, suggest a system that suits your floor build-up and explain how it will be controlled.
When Underfloor Heating Makes Sense
- You're building an extension and the floor hasn't been laid yet
- Radiators would get in the way of kitchen units or glazing
- Tiled floors feel cold underfoot in the morning
- You want the whole room evenly warm rather than hot near a radiator
- You're planning a heat pump now or in the future
- A bathroom refit is a chance to add a heated floor
Wet or Electric?
- Wet system in screed – the most efficient choice for extensions and new floors
- Low-profile wet system – for existing floors where height is tight
- Wet system between joists – for upper floors and suspended timber floors
- Electric mat – quick to fit under tiles in bathrooms and small kitchens
- Electric foil or cable – under laminate, wood or vinyl floors
- Controls – a thermostat in each room or zone, including smart options
Underfloor Heating Prices in Swansea
The cost of underfloor heating in Swansea depends on the floor area, wet or electric, the existing floor and whether screed and finishes are part of the job. As a guide:
| Project | Typical cost in Swansea (inc. VAT) |
|---|---|
| Electric underfloor heating in a bathroom | £1,000 – £2,000 |
| Wet system in a 20–40m² extension | £2,500 – £4,500 |
| Wet system across a ground floor | £4,500 – £7,500+ |
Electric mats are cheaper up front but dearer to run over large areas, so for anything bigger than a bathroom, a wet system usually works out better value over time.
Regulations and Local Guidance in Swansea
You won't need planning permission for underfloor heating in an existing room. An extension will need building regulations approval, including the floor insulation beneath the heating, and electric systems on a new circuit should be fitted by a registered electrician.

Before pipe or mats go down, the installer should check insulation, available floor height, heat loss and the final floor finish. Wet systems need manifold and mixing arrangements where appropriate; electric mats need suitable electrical protection and testing.
Heating questions answered
How much does underfloor heating cost in Swansea?
Underfloor heating in Swansea typically costs between £1,000 and £7,500. A single bathroom with an electric mat is the cheapest type of job, and a fully screeded wet system under an entire ground floor is the most expensive.
How long does underfloor heating take to install?
An electric mat in a bathroom can be laid in a day. A wet system in an extension takes one to five days to install, but screed then needs several weeks to dry before floor finishes go down.
Does underfloor heating raise the floor level?
Low-profile systems and electric mats add only a few millimetres to a couple of centimetres. Screeded systems need more depth, which is easiest to allow for in a new extension.
Can I have underfloor heating and radiators together?
Yes. Many homes run underfloor heating downstairs and radiators upstairs from the same boiler, with a mixing valve keeping the underfloor circuit at a lower temperature.
