What to know about air-to-air heat pumps in Didcot
Every property in Didcot 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 Didcot plan condensate drains and pipe covers so indoor and outdoor runs stay neat. Top-floor rooms in Didcot 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.
- Extensions, conservatories and garden rooms
- Flats and apartments with storage or panel heaters
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Outdoor unit and indoor units for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Free survey covering rooms to heat, unit positions and hot water options
- Condensate drains and neat external pipe covers
- Commissioning, MCS certificate and the air-to-air grant claim in England and Wales where eligible
For terraced homes in Didcot, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
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 Didcot quote.
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.
What to budget for air-to-air heat pumps in Didcot
Here are typical prices for air-to-air heat pumps in Oxfordshire, installed and including VAT. Use the guide price tool for a figure based on your home, then a survey confirms it in writing.

How long is the heating season in Didcot?
Didcot has about 7 hours 48 minutes of daylight at midwinter and 16 hours 40 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.

Air-to-air heat pumps in Didcot: questions
Can you service a heat pump in Didcot that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Didcot, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Didcot?
Survey dates depend on how busy installers are in Oxfordshire. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Didcot 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 Didcot home.
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.
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.
