Your questions about air source heat pumps in Hartfield
Can I get the Boiler Upgrade Scheme grant in Hartfield?
Yes, if the home and the heat pump meet the scheme’s rules: Hartfield is in England, where it applies. 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 isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Will you come out to Hartfield?
Yes. Hartfield is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone and we will gladly show you ours.
Is a heat pump permitted development?
Often not in England, as many heat pumps on houses are permitted development provided the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.
Will skipping a service affect the warranty?
That depends on the brand. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim, so we explain the terms on your 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 prices are set after a survey, and we confirm the VAT on the quote.
About our air source heat pumps in Hartfield
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We are often asked to deal with radiators that may be too small for a heat pump and ageing boilers that will need replacing, on underfloor heating, air-to-water heat pumps and hot water cylinders.
In a place like Hartfield, some homes are listed, and permitted development does not cover listed buildings, so we check consent first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What a heat pump looks like in Hartfield
Central Hartfield is inside the Hartfield Conservation Area. Listed buildings are part of the picture here: about 26 within half a mile of the centre, such as The Parish Church of St Mary (grade I). For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the planning team at Wealden council, which typically handles Hartfield where necessary. About 74% of households live in detached or semi-detached houses, according to the 2021 Census. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
Historic houses such as Bassetts Manor, about 1.5 miles north-west, are a reminder that listed homes need consent before a heat pump goes in. Period properties close to The Parish Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first.
Hartfield is about 4 miles north-west of Crowborough, in East Sussex.

Leave it or put it right?
Permitted development rules can change, and conditions vary between properties. Checking the position for your home at the survey stage avoids surprises later, including conservation areas, listed buildings and Article 4 directions. Waiting rarely makes an air conditioning problem smaller.

What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the existing unit help with repairs and servicing in Hartfield.

Advice
What you can do yourself, and what needs us
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749 or use the quote form.
For landlords and property managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we are happy to deal with whoever it is.
Keeping records across a portfolio is half the battle. Every visit is written up, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
