Wet underfloor heating is a network of plastic pipes laid under the floor that carries warm water from the heat pump and turns the whole floor into a large, low-temperature radiator. Because the heating surface is so big, it can keep a room comfortable with water at around 35–40°C, which is the range where heat pumps typically work most efficiently.
Homeowners in Leicestershire and across Leicestershire can mix underfloor heating downstairs with radiators upstairs on one heat pump. Older houses around Leicestershire with suspended timber floors can often take underfloor pipes between the joists. We coordinate with builders working in Leicestershire so underfloor pipes are laid and tested before the screed goes down.
Who it suits
- 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
- Homeowners who want even, gentle warmth with no radiators on show
Grants and rules for heat pumps in England
Homes in Leicestershire 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.

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 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.
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.
