Underfloor heating can cover one room, an extension or the whole ground floor, and it works alongside radiators upstairs. We design it from the same room-by-room heat loss figures as the rest of the system, set out pipe spacing and zones for each room, and confirm which floor finishes will let the heat through.
For homes in Clwyd with solid ground floors, a low-profile overlay system can avoid breaking up the existing floor. Homeowners in Clwyd and across Clwyd can mix underfloor heating downstairs with radiators upstairs on one heat pump. We coordinate with builders working in Clwyd so underfloor pipes are laid and tested before the screed goes down.
Who it suits
- Ground floors being dug out or relaid as part of wider building work
- Homeowners who want even, gentle warmth with no radiators on show
- Rooms where wall space for radiators is scarce
- Self-builds and new floors where insulation and screed are going in anyway
Grants and rules for heat pumps in Wales
Homes in Clwyd can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Underfloor heating with a heat pump questions
How much does underfloor heating cost with a heat pump?
Wet underfloor heating for a whole ground floor has a guide price of £5,000–£15,000, installed and including VAT, and a single room has a guide price of £1,500–£3,500. The spread reflects floor type, area, whether an overlay or screed system is used and how much floor preparation is needed. Your written quote fixes the price after the survey.
How long does a screed floor take before I can use the heating?
Screed needs to dry before the heating is used at full temperature and before most floor finishes are laid. Drying time depends on the screed type, depth and conditions, from around a week for some liquid screeds to several weeks or more for traditional sand and cement. The heating is then brought up gradually over several days to avoid cracking.
How much will an overlay system raise my floor?
A low-profile overlay system typically adds around 15–25 mm for the boards, plus the thickness of the new floor finish. That can be enough to need door trimming, threshold strips and adjustments where the floor meets kitchen units or stairs. We measure these details at the survey so the build-up is agreed before work starts.
Can I put carpet over underfloor heating?
Yes, as long as the carpet and underlay together have a low tog rating, which measures how much they resist heat. For heat pump systems a combined figure of around 1.5 tog or less is a common target. Thick carpet on heavy underlay can cut output noticeably, so rooms with carpet may need closer pipe spacing.
