Let and managed properties
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
Air source heat pumps in Sweethaws
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation and the installer makes the application. Not every home qualifies, so we check eligibility before you commit. The work covers underfloor heating, homes heated by oil, LPG or gas and radiator systems, and common reasons people get in touch are questions about where the outdoor unit can go and moving away from fossil-fuel heating.
In a place like Sweethaws, some homes are listed, because permitted development does not apply within the grounds of a listed building, so we check consent first.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight and each visit is recorded.

What you can do yourself, and what needs us
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 a breaker trips again after you reset it, leave it off and phone 07833 053749.
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.

Your questions about air source heat pumps in Sweethaws
Is planning permission needed for a heat pump in Sweethaws?
There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 4 buildings and structures within half a mile of the centre of Sweethaws. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Wealden council, which is typically the planning authority for Sweethaws.
Do you cover smaller places like Sweethaws?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is there VAT on a heat pump?
For homes, 0% until 31 March 2027, under HMRC Notice 708/6, then 5%. For air-to-air systems, we confirm the VAT on your quote.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. We check them all during the survey, so the quote covers any changes.
How long does a heat pump installation take?
Expect it to take a few days on site, depending on the cylinder, the radiators and the pipework involved. How much of the heating changes decides most of the time and the timing is set out with your quote.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
What happens on the day
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. Work in Sweethaws is booked in advance at a time that suits you.

Keeping the system healthy
Aftercare is straightforward, and it helps at the next service:
- Keep radiators clear
- Avoid switching the heat pump on and off often
- File the MCS certificate safely
The warranty on the heat pump is the manufacturer’s, on its own terms. We explain the terms for your brand, including any servicing conditions.
Keep radiators and indoor units unobstructed so the heat can get into the room.
A customer’s words
“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.”
