What to know about air-to-air heat pumps in Paisley
Every property in Paisley is different, so the design starts from measurements rather than a rule of thumb. That keeps the system the right size and the running costs predictable.
Extensions and garden rooms in Paisley that are hard to connect to the main heating can have their own air-to-air unit. A survey in Paisley covers indoor unit positions, pipe routes and hot water for homes across Renfrewshire and Inverclyde.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Homes where fitting radiators and pipework would be very disruptive
- Extensions, conservatories and garden rooms
- Rooms that get too hot in summer as well as cold in winter
What's included
- Free survey covering rooms to heat, unit positions and hot water options
- Outdoor unit and indoor units for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Electrical supply and controls set up for each room
- Condensate drains and neat external pipe covers
Top-floor rooms in Paisley that overheat in summer gain from the cooling an air-to-air system provides.
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 Paisley home, apply and receive the written offer before the installation date is fixed.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Scotland has its own permitted development rules for air source heat pumps and its own building standards, so we confirm what applies to your Paisley property at survey.
Air-to-air heat pumps costs around Paisley
The ranges below are typical installed prices for homes in Renfrewshire and Inverclyde, including VAT. A survey sets the exact figure, because two similar-looking houses in Paisley can need quite different radiators and pipework.

|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,400–£5,000 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,000–£8,000 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water.
How long is the heating season in Paisley?
Paisley has about 6 hours 59 minutes of daylight at midwinter against 17 hours 35 minutes in midsummer. Heat pumps are designed to keep working well below freezing, but the design temperature for the survey is set for local conditions, not an average day.

Air-to-air heat pumps in Paisley: questions
Can you service a heat pump in Paisley that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Paisley, whoever fitted them. Tell us the make and model when you book.
What size heat pump does a Paisley home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Paisley home.
Do you cover Barrhead as well as Paisley?
Yes. We arrange surveys and installation in Barrhead, which is about 3 miles south-east of Paisley, and across Renfrewshire and Inverclyde.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
Is there a grant for air-to-air heat pumps?
In England and Wales, yes: the Boiler Upgrade Scheme includes a grant of £2,500 for air-to-air heat pumps in homes, from 28 April 2026. The MCS-certified installer applies to Ofgem and deducts it from your quote, subject to the scheme's conditions. The scheme does not cover Scotland or Northern Ireland; in Scotland, Home Energy Scotland has its own rules.
