Before you book: air-to-air heat pumps in St Helens
Every property in St Helens 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.
Installers in St Helens plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Flats in St Helens on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
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.
- Flats and apartments with storage or panel heaters
- Extensions, conservatories and garden rooms
- Households that already have, or will add, a separate source of hot water
What's included
- Condensate drains and neat external pipe covers
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Free survey covering rooms to heat, unit positions and hot water options
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Outdoor unit and indoor units for each room
Top-floor rooms in St Helens that overheat in summer gain from the cooling an air-to-air system provides.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your St Helens quote.
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.
Air-to-air heat pumps costs around St Helens
Guide prices for St Helens and the rest of Merseyside are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.

| Air-to-air heat pump, multi-room 3–4 bedroom home | £3,900–£7,750 |
Installed, inc VAT. Air-to-air systems heat (and can cool) rooms but do not provide hot water. In England and Wales the Boiler Upgrade Scheme gives £2,500 towards an air-to-air system in a home, deducted from your quote where eligible.

Air-to-air heat pumps in St Helens: questions
How long does installation take in St Helens?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a St Helens home states the expected time.
Do you cover Prescot as well as St Helens?
Yes. We arrange surveys and installation in Prescot, which is about 3 miles south-west of St Helens, and across Merseyside.
How long does a heat pump survey take in St Helens?
A home survey in St Helens usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
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.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
