How we handle air source heat pumps in Holwellbury
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home, so an add-on next to a boiler is not eligible. Typical jobs include moving away from fossil-fuel heating and checking whether planning permission is needed, on radiator systems, air-to-air heat pumps and hot water cylinders.
If your home in or near Holwellbury is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

When it’s something else
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- Planning decisions, which rest with the council
- Insulation work, such as loft or cavity wall insulation
- Grants for hybrid systems or replacements of low-carbon systems
Not sure which it is? You can phone 07833 053749 or email us and we’ll tell you honestly.
Parts of the system we cover
- Homes heated by oil, LPG or gas
- Air-to-water heat pumps
- Underfloor heating
- Air-to-air heat pumps
- Radiator systems
- Hot water cylinders
Rented and managed buildings
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
Pricing air source heat pumps in Holwellbury
The survey or diagnosis tells us what the work involves. The main factors are:
- Whether it’s a simple split or a larger system
- One-off work versus a regular service cycle
- How far the pipework has to run, and where
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re not sure what’s needed, ring us on 07833 053749 or send an email and we’ll give you an honest view and a fixed price.
Asking for a quote
What to send for a quote:
- The outside wall, roof or yard where the outdoor unit sits or would go
- Photos showing the indoor unit and the space around it
- The remote or wall controller showing any error
Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To get going, call 07833 053749 or drop us a line.

Homes in Holwellbury and heat pumps
Holwellbury is about 35 miles from central London, well within the area we cover from our base in East Grinstead. About 41% of homes in Holwellbury and the neighbourhoods around it have been built since 2000, according to the Valuation Office Agency’s council tax figures, and about 71% of households live in detached or semi-detached houses, according to the last census (2021). Better insulated, newer homes are often a good match for 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 Peter (C of E) at Corner with Holwell Road? Expect the survey to look closely at heat loss and at the building’s planning status. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Your questions about air source heat pumps in Holwellbury
Is Holwellbury in your area for air source heat pumps?
Yes. Holwellbury is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Will you come out to Holwellbury?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
How long does a heat pump installation take?
A typical installation takes a few days for most air-to-water installations, with air-to-air systems often quicker. We plan the work so you are without heating for as little time as possible and agreed before we start.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water suits homes with radiators and a cylinder; air-to-air suits rooms that need heating and cooling. The survey helps decide. Both are part of what we install.
Will I get records for the system?
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.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for example, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
What a customer said
“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.”
