Air-to-air heat pumps for Stevenage homes
A heat pump suits most Stevenage homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Installers in Stevenage plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Flats in Stevenage 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.
- Homes where fitting radiators and pipework would be very disruptive
- Households that already have, or will add, a separate source of hot water
- Flats and apartments with storage or panel heaters
What's included
- Outdoor unit and indoor units for each room
- Electrical supply and controls set up for each room
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Condensate drains and neat external pipe covers
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
Extensions and garden rooms in Stevenage that are hard to connect to the main heating can have their own air-to-air unit.
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 Stevenage 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.
What to budget for air-to-air heat pumps in Stevenage
Guide prices for Stevenage and the rest of Hertfordshire 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.
| System | Installed guide price |

| Air-to-air heat pump, 1–2 rooms | £2,500–£5,250 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,200–£8,400 |
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.
Short winter days in Stevenage and what they mean
On the shortest day Stevenage gets about 7 hours 45 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air-to-air heat pumps in Stevenage: questions
Do I need new radiators for a heat pump in Stevenage?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Stevenage home gives a room-by-room list.
How soon can you survey a home in Stevenage?
Survey dates depend on how busy installers are in Hertfordshire. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Stevenage?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Stevenage home states the expected time.
Can air-to-air heat pumps cool as well as heat?
Yes. Most air-to-air systems can reverse their cycle to cool and dehumidify rooms in summer, which makes them useful for loft rooms, south-facing extensions and home offices that overheat. Cooling uses electricity, so running costs rise if it is used heavily. You control heating and cooling for each room separately.
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.
