Before you book: air source heat pump installation in Witney
Every property in Witney 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.
In Witney, cylinder space is planned with you, often in an airing cupboard, utility room or garage. For older properties in Witney, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
- Houses with reasonable insulation, or a plan to improve it
What's included
- Removal of the old boiler or heaters
- Boiler Upgrade Scheme application in England and Wales where eligible
- System design, unit sizing and a written quote
- Free home survey and room-by-room heat loss calculation
- Outdoor unit, hot water cylinder and weather compensation controls
Homeowners across Oxfordshire can arrange a survey in Witney for a room-by-room design and a written quote before committing to anything.
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 Witney 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.

Designing for Witney's winters
Witney has about 7 hours 47 minutes of daylight at midwinter and 16 hours 42 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 source heat pump installation in Witney: questions
How long does a heat pump survey take in Witney?
A home survey in Witney 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.
Do I need new radiators for a heat pump in Witney?
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 Witney home gives a room-by-room list.
Can you service a heat pump in Witney that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Witney, whoever fitted them. Tell us the make and model when you book.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
