Advice
Air source heat pumps in Horsted Keynes, done properly
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. Typical jobs include moving away from fossil-fuel heating and no space for a hot water cylinder, on hot water cylinders, air-to-water heat pumps and air-to-air heat pumps.
Homes around Horsted Keynes typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Air source heat pumps around Horsted Keynes
The Horsted Keynes Conservation Area lies close to the centre of Horsted Keynes, within about a third of a mile. Listed buildings are part of the picture here: about 27 within half a mile of the centre, such as Parish Church of St Giles (grade I). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at Mid Sussex council, which typically handles Horsted Keynes. About 79% of households live in detached or semi-detached houses, according to the last census (2021). Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
With Priest House about 3 miles north-west, it’s worth asking whether your own home is listed before planning a heat pump. Period properties close to St Giles' Church can suit a heat pump, though insulation and any heritage protection are checked first.

Your questions about air source heat pumps in Horsted Keynes
Is the heat pump grant available in Horsted Keynes?
Yes, if the home and the heat pump meet the scheme’s rules: Horsted Keynes 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. We hold MCS certification, so the application is ours to make for you.
Is Horsted Keynes within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and photos, and we reply the same working day.
Do you provide F-Gas records?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Should I choose air-to-water or air-to-air?
The right choice depends on the property and what you need. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Will my radiators work with a heat pump?
It depends on each radiator and the room it heats. Heat pumps run at lower flow temperatures, so radiators give out less heat so we check every radiator against the room’s heat loss.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. You get a fixed price before any work goes ahead.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
What affects the cost of air source heat pumps
The price is fixed before any work begins. It’s based on:
- A single visit or a regular plan
- Which make and model is being fitted or worked on
- How many units are involved
Typical ranges are on our prices page, but your price depends on the job in front of us. Call for a fixed-price quote, and we’ll talk you through it.
What to send for a quote
To speed up the quote, send us:
- Where the property is and what kind of building it is
- The remote or wall controller showing any error
- The outdoor side of the property, including any roof or flat area

What you can do yourself, and what needs us
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
