Owner checks or an engineer?
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Before you call us about a fault, a few checks can save a visit: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and call 07833 053749 or write to us at info@aircondoctor.co.uk.
How we handle air source heat pumps in Twelve Oaks
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. If you are dealing with no space for a hot water cylinder and an oil, LPG or gas boiler near the end of its life, we can help.
Space for an outdoor unit is rarely an issue near Twelve Oaks, so the design focuses on heat loss and radiators.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What air conditioning won’t do
We’d rather tell you now than sell you work that will not help, so these are the things it won’t cover:
- Promising eligibility for the Boiler Upgrade Scheme
- Disconnecting or servicing a gas boiler
- Improving the building’s insulation
Not sure which it is? You can give us a ring on 07833 053749, or email if that’s easier and we’ll tell you honestly.

What we are called out for in Twelve Oaks
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
Look out for these signs:
- Deciding on the outdoor unit position
- Wanting to stop using oil, LPG or gas for heating
- Working out where a cylinder could go
Bateman's, roughly 2.4 miles north-west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.
What your quote should include
- Whether you get F-Gas records where refrigerant is involved
- Proof of F-Gas company certification
- Whether a new circuit is included and who certifies it
Twelve Oaks questions
Do you cover smaller places like Twelve Oaks?
We do. Villages and hamlets get the same service as the bigger towns. A few pictures and the postcode are enough to get things started.
Does the Boiler Upgrade Scheme cover homes in Twelve Oaks?
Yes, if the home and the heat pump meet the scheme’s rules: Twelve Oaks is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. As an MCS certified installer, we apply for it on your behalf.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we’ll take it from there.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Either way, keep a record of every service.
How much does an air source heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. The heat pump size, radiator changes and the cylinder decide where in that range you are. Air-to-air is priced after a survey.

Air source heat pumps in Twelve Oaks: the local picture
The middle of Twelve Oaks is part of a conservation area. On the National Heritage List, around 15 entries fall within 0.5 miles of the middle of Twelve Oaks; The Parish Church of St Thomas a Becket (grade I) is one. For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with Rother council, typically the planning authority here where needed. VOA council tax data put about 42% of homes in the Twelve Oaks area before 1919, and about 80% of households live in detached or semi-detached houses, according to the last census (2021). In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is one of the older properties near The Parish Church of St Thomas A Becket, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
