Air source heat pump installation is the full job of replacing your heating with an air-to-water system: a survey and room-by-room heat loss calculation, the outdoor unit, a hot water cylinder, controls, any radiator or pipework changes, commissioning and registration. A heat pump takes heat from the outside air using a refrigerant cycle and delivers it to your radiators or underfloor heating and to a cylinder of stored hot water. In a well-designed system it typically produces about 3–4 units of heat for every unit of electricity it uses.
Homeowners across Perth and Kinross can arrange a survey in Perth and Kinross for a room-by-room design and a written quote before committing to anything. Many homes in Perth and Kinross have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows. In Perth and Kinross, cylinder space is planned with you, often in an airing cupboard, utility room or garage.
Who it suits
- Households with room for a hot water cylinder
- Houses with reasonable insulation, or a plan to improve it
- Owners who want one contract covering design, fitting and paperwork
- Homes replacing a gas, oil, LPG or electric heating system
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.

Air source heat pump installation questions
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
