Cassington air source heat pumps
Looking for air source heat pumps in Cassington? We diagnose first, fix the price and book the work around you, then sign it off with written records.
- Checking eligibility for a heat pump grant
- Checking whether planning permission is needed
- An oil, LPG or gas boiler near the end of its life
How the visit works
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. The work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. We agree a date with you and plan the visit to Cassington so we arrive with what’s needed.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Keep pets out of the rooms we are working in
- Let us know if the units are on a roof, a high wall or in a locked area
How to get a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Air source heat pumps in Cassington, done properly
We install air source heat pumps in Cassington and across Oxfordshire, and we’re MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We’ll explain which type fits your home and why. If you are dealing with no space for a hot water cylinder and comparing heat pump types, we can sort it out.
In a place like Cassington, some homes are listed, and permitted development does not cover listed buildings, so we check consent first.
Looking after a system is mostly common sense: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Rented and managed buildings
Keeping records across a portfolio is half the battle. Each visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
What a heat pump looks like in Cassington
The Valuation Office Agency’s council tax figures date about 40% of homes in and around Cassington to the post-war years, 1945 to 1972, and about 71% of households live in detached or semi-detached houses, according to the 2021 Census. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses typically have space for an outdoor unit and a hot water cylinder.
If your home is listed, like Blenheim Palace about 3.4 miles north, listed building consent comes before any heat pump work. Older homes near Church of St Peter may need extra checks for planning and heat loss before a heat pump is designed.
Cassington is about 6 miles north-west of Oxford, in Oxfordshire. Whatever kind of property you have in Cassington, we can help with air source heat pumps.

Questions from Cassington
Will a heat pump in Cassington need planning permission?
That depends on the building and where the outdoor unit goes. The centre of Cassington is in the Cassington Conservation Area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Cassington, usually West Oxfordshire council).
Is Cassington within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
What VAT do I pay on a heat pump?
Under HMRC Notice 708/6, a heat pump installed in a home is zero-rated until 31 March 2027 and 5% after that. With air-to-air, HMRC’s view depends on the product, so we confirm the VAT on the quote.
What does an air-to-water heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
When will I hear back?
The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Will I get records for the system?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
What air source heat pumps cannot fix
We won’t sell you work that doesn’t address the problem, so here are the limits:
- Promising eligibility for the Boiler Upgrade Scheme
- Planning approval where permitted development doesn’t apply
- Insulation work, such as loft or cavity wall insulation
If you are not sure, just call 07833 053749 or drop us a line and we’ll give you a straight answer.

Fixed-price quotes for air source heat pumps in Cassington
The quote reflects the job in front of us. We take into account:
- How easy the units are to reach

- Whether it’s a simple split or a larger system
A single unit or a whole estate, the quote is built the same way: what needs doing, how we get to it and what it needs. You will have a fixed price before work begins, and the quote sets out the VAT.
What we need to know
Before you ask for a quote, gather:
- The address and the type of property
- Photos showing the indoor unit and the space around it
- The make and model of the system, from the label
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, call 07833 053749, or email if that’s easier.
