Air source heat pumps for homes and businesses in Four Throws
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. We’re often asked to deal with radiators that may be too small for a heat pump and plans to switch to electric heating with a heat pump, across underfloor heating, air-to-water heat pumps and radiator systems.
Homes around Four Throws usually have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a village like Four Throws, tell us about narrow lanes, gates and parking when you book.

- Tax advice on your own circumstances
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
If you are not sure, just ring 07833 053749 or write to us at info@aircondoctor.co.uk and we will give you a straight answer.

Your questions about air source heat pumps in Four Throws
Will you come out to Four Throws?
Yes. Four Throws is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Does the Boiler Upgrade Scheme cover homes in Four Throws?
Yes, if the home and the heat pump meet the scheme’s rules: Four Throws is in England, where it applies. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You don’t apply yourself: the MCS certified installer does, which is us.
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.
Does servicing affect my warranty?
For some brands, yes. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Do you provide F-Gas records?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
How long does a heat pump installation take?
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. The survey lets us set a firm programme, and you can ring 07833 053749 or drop us a line to book it.
Will my radiators work with a heat pump?
It depends on each radiator and the room it heats. At the lower temperatures a heat pump uses, radiators need more surface, and the survey checks each one.

Do you need air source heat pumps in Four Throws?
Air-to-air systems interest people who want cooling in summer as well as heating. They warm rooms directly through indoor units, and can cool them when it’s hot. The grant only applies in some cases, so we check first.
These are the situations we see most often:
- Comparing heat pump types
- Checking whether planning permission is needed
- Not knowing whether a grant applies
Period properties close to Church of All Saints can suit a heat pump, though insulation and any heritage protection are checked first.
What your quote should include
- Whether they looked at the job before pricing it
- What happens if the job turns out to be different on the day
- Proof of F-Gas company certification
What a heat pump looks like in Four Throws
About 38% of homes across Four Throws and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and the last census (2021) found about 72% of households in detached or semi-detached houses. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Houses normally have space for an outdoor unit and a hot water cylinder. The centre of Four Throws lies within a conservation area. About 18 listed entries lie within half a mile of central Four Throws, Field Green House (grade II*) among them. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
If your home is listed, like Great Dixter about 3.9 miles south-east, listed building consent comes before any heat pump work.
