Air source heat pumps in Hall's Green
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. If you’re dealing with finding a place for the outdoor unit and working out where a cylinder could go, we can sort it out.
If your home in or near Hall's Green is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. Keep it with the system’s paperwork so it’s to hand next time.

Questions from Hall's Green
Is Hall's Green within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and photos, and we reply the same working day.
Does the Boiler Upgrade Scheme cover homes in Hall's Green?
Hall's Green is in England, where the Boiler Upgrade Scheme runs. 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.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
How much time does a heat pump install need?
An installation 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 confirm the timing after the survey, and you can ring us on 07833 053749 or write to us at info@aircondoctor.co.uk to book it.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. It’s worth checking before booking and we will gladly show you ours.
What does an air-to-water heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme, and we confirm eligibility before you commit.
What warranty do I get?
The manufacturer provides it, on its own terms. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Air source heat pumps around Hall's Green
Central Hall's Green is inside a conservation area. Listed buildings are part of the picture here: about 4 within half a mile of the centre, such as The Cottage (grade II). Where a home is affected, the outdoor unit position is settled with the local planning authority (typically Sevenoaks council) before the heat pump design is finished. About 46% of homes in Hall's Green and the neighbourhoods around it were built before 1919, according to VOA council tax data, and about 73% of households live in detached or semi-detached houses, according to Census 2021 figures. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Houses typically have space for an outdoor unit and a hot water cylinder.
Live in one of the older houses around Church of St George? Expect the survey to look closely at heat loss and at the building’s planning status. Historic houses such as Knole House, about 3.1 miles north, are a reminder that listed homes need consent before a heat pump goes in.

Managing agents and facilities teams in Hall's Green
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so each one has its own history.
How the visit works
Each visit runs to the same pattern: check the plan with you, protect the area, do the work, test what we’ve done and talk you through it. On site, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Rural lanes and tight entrances are worth mentioning before a visit to Hall's Green.
- It begins with your house and the heating it relies on now.

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.”
