Before you book: air-to-air heat pumps in Letchworth Garden City
A heat pump suits most Letchworth Garden City homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
For terraced homes in Letchworth Garden City, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room. Extensions and garden rooms in Letchworth Garden City that are hard to connect to the main heating can have their own air-to-air unit.
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.
- Extensions, conservatories and garden rooms
- Rooms that get too hot in summer as well as cold in winter
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Electrical supply and controls set up for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Outdoor unit and indoor units for each room
- Condensate drains and neat external pipe covers
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
Flats in Letchworth Garden City on storage or panel heaters can often switch to air-to-air without fitting radiators or pipework.
Grants and rules for heat pumps in England
Homes in Letchworth Garden City can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Air-to-air heat pumps in Letchworth Garden City: questions
Can you service a heat pump in Letchworth Garden City that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Letchworth Garden City, whoever fitted them. Tell us the make and model when you book.
How long does a heat pump survey take in Letchworth Garden City?
A home survey in Letchworth Garden City 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.
How long does installation take in Letchworth Garden City?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Letchworth Garden City 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.
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.
