Before you book: air-to-air heat pumps in Ely
Most homes can run on a heat pump if the system is designed properly, and Ely is no different. The key is matching the heat pump and radiators to the home's heat loss.
Extensions and garden rooms in Ely that are hard to connect to the main heating can have their own air-to-air unit. Top-floor rooms in Ely that overheat in summer gain from the cooling an air-to-air system provides.
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.
- Households that already have, or will add, a separate source of hot water
- Extensions, conservatories and garden rooms
- Rooms that get too hot in summer as well as cold in winter
What's included
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
- Outdoor unit and indoor units for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Electrical supply and controls set up for each room
A survey in Ely covers indoor unit positions, pipe routes and hot water for homes across Cambridgeshire.
Grants and rules for heat pumps in England
Homes in Ely 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.
Guide prices for air-to-air heat pumps in Ely
These are guide prices for Cambridgeshire, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.
| System | Installed guide price |
|---|---|
| Air-to-air heat pump, 1–2 rooms | £2,450–£5,100 |
| Air-to-air heat pump, multi-room 3–4 bedroom home | £4,100–£8,150 |
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.
How long is the heating season in Ely?
On the shortest day Ely gets about 7 hours 40 minutes of daylight, with the noon sun around 14° 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.

- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Air-to-air heat pumps in Ely: questions
Where would the outdoor unit go on an Ely house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Ely home.
How long does installation take in Ely?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Ely home states the expected time.
What size heat pump does an Ely 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 Ely home.
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.
