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.
We coordinate with builders working in Perth and Kinross so underfloor pipes are laid and tested before the screed goes down. Older houses around Perth and Kinross with suspended timber floors can often take underfloor pipes between the joists. Every underfloor design for Perth and Kinross starts with the floor finish you plan to lay, from tiles to carpet.
Who it suits
- Rooms where wall space for radiators is scarce
- Self-builds and new floors where insulation and screed are going in anyway
- Homeowners who want even, gentle warmth with no radiators on show
- Extensions, especially open-plan kitchen-diners with large glazed areas
Grants and rules for heat pumps in Scotland
In Scotland, heat pump funding comes through Home Energy Scotland rather than the Boiler Upgrade Scheme: a grant of up to £7,500 (up to £1,500 extra for eligible rural and island homes) and an optional interest-free loan of up to £7,500. For a home in Perth and Kinross, apply and receive the written offer before the installation date is fixed.
There is no VAT on installing a heat pump anywhere in the UK, Scotland included, until 31 March 2027. Scottish permitted development rules and building standards apply, and the surveyor checks the unit position and any listed or conservation-area constraints.

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.
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 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.
