Deddington air source heat pumps
Air source heat pumps across Deddington and nearby, from a site survey or diagnosis to sign-off with the price fixed before work begins.

What you can do yourself, and what needs us
Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Air source heat pumps for homes and businesses in Deddington
We install air source heat pumps in Deddington and across Oxfordshire, and we are MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We’ll explain which type fits your home and why. The work covers air-to-water heat pumps, hot water cylinders and air-to-air heat pumps, and common reasons people get in touch are questions about the Boiler Upgrade Scheme and deciding which kind of heat pump suits the home.
If your home in or near Deddington is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Homes in Deddington and heat pumps
The centre of Deddington lies within the Deddington Conservation Area. On the National Heritage List, around 100 entries fall within 0.5 miles of the middle of Deddington; The Leadenporch House (grade I) is one. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? About 34% of homes in the Deddington area have been built since 2000, according to VOA council tax data, and the last census (2021) found about 79% of households in detached or semi-detached houses. Better insulated, newer homes are often a good match for a heat pump. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Broughton Castle, roughly 5 miles north-west, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.

Deddington: your questions answered
Does the Boiler Upgrade Scheme cover homes in Deddington?
Yes, the scheme covers homes in England, including Deddington, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
Will you come out to Deddington?
Yes. Deddington is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
How much time does a heat pump install need?
The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. The survey lets us set a firm programme, so ring 07833 053749, or email if that’s easier to arrange one.
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
What does an air-to-water heat pump cost?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Do I need new radiators for a heat pump?
Some radiators may be fine as they are, and some may need to be larger. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
How the visit works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, and that 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. For a place like Deddington, the timing is set with you and the travel is our side of the planning.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Installation, commissioning and MCS registration complete the job.
Getting ready for the visit
- Mention any parking restrictions near the property
- Make sure we can reach the outdoor unit, or where it will go
- Move furniture away from the wall where we will be working
How to get a quote
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To get going, phone us on 07833 053749 or send an email.

What we are called out for in Deddington
Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
Most people get in touch when they notice one of these:
- Questions about listed buildings or conservation areas
- Moving away from fossil-fuel heating
- Deciding on the outdoor unit position
Older homes near Church of St Peter and St Paul may need extra checks for planning and heat loss before a heat pump is designed.
What your quote should include
- Whether they looked at the job before pricing it
- Exactly what the price includes, from supply and fitting to commissioning
- Which VAT rate the quote uses, and why
What affects the quote in Deddington
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether it’s a simple split or a larger system
- The electrical supply and whether a new circuit is needed
- How far the pipework has to run, and where
Putting several jobs into one visit often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
Before you get in touch
When you call or email, it’s useful to have:
- Your consumer unit or fuse board
- The paperwork from the last service, if you have it
- Wide pictures of the room or the existing unit
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
