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.
Kitchen extensions in Lincolnshire are often the natural place to add underfloor heating when a heat pump goes in. Older houses around Lincolnshire with suspended timber floors can often take underfloor pipes between the joists. We coordinate with builders working in Lincolnshire so underfloor pipes are laid and tested before the screed goes down.
Who it suits
- Rooms where wall space for radiators is scarce
- Self-builds and new floors where insulation and screed are going in anyway
- Ground floors being dug out or relaid as part of wider building work
- Extensions, especially open-plan kitchen-diners with large glazed areas
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Underfloor heating with a heat pump questions
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.
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.
Is underfloor heating better than radiators with a heat pump?
Underfloor heating usually allows a lower flow temperature than radiators, which helps a heat pump run efficiently. That does not make radiators a poor choice: correctly sized radiators also work well, and they are far less disruptive to fit in existing rooms. Many homes use underfloor heating in an extension or on the ground floor and radiators elsewhere.
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.
