There are two main ways to fit it. In new floors, such as an extension or a ground floor being dug out, pipes are set into a screed: a layer of sand and cement, or a flowing liquid mix, laid over insulation. In existing rooms, a low-profile or overlay system uses thin grooved boards laid on top of the current floor, raising it by a modest amount instead of breaking it up.
Every underfloor design for Kent starts with the floor finish you plan to lay, from tiles to carpet. Older houses around Kent with suspended timber floors can often take underfloor pipes between the joists. We coordinate with builders working in Kent so underfloor pipes are laid and tested before the screed goes down.
Who it suits
- Rooms where wall space for radiators is scarce
- Extensions, especially open-plan kitchen-diners with large glazed areas
- Ground floors being dug out or relaid as part of wider building work
- Self-builds and new floors where insulation and screed are going in anyway
Grants and rules for heat pumps in England
Homes in Kent can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
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.

| Wet underfloor heating, whole ground floor | £5,150–£15,450 |
Installed, inc VAT. Floor finishes and screed drying time are confirmed at survey.

Underfloor heating with a heat pump questions
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.
Can I heat just one room with underfloor heating?
Yes. A single room, such as a kitchen extension, can have its own underfloor zone connected to the heat pump alongside the radiators in the rest of the house. It needs its own thermostat and a manifold, which for one room can be compact. The design checks the room's heat loss so the floor can meet it at the system's flow temperature.
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.
