Air source heat pumps in Elsted Marsh, done properly
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. 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; adding it alongside a boiler does not qualify. Common call-outs are for not knowing whether a grant applies and a boiler that’s getting old, across hot water cylinders, air-to-water heat pumps and underfloor heating.
Homes around Elsted Marsh normally have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
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.

Leave it or put it right?
If the emitters can’t give out enough heat, some rooms won’t get warm enough. Checking and upsizing them as part of the installation avoids that. A dirty or faulty system works harder and costs more to run.
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. You will have a fixed price before work begins, with VAT shown clearly.

Air source heat pumps around Elsted Marsh
About 41% of homes in the Elsted Marsh area were built before 1919, according to Valuation Office Agency council tax records, and about 82% of households live in detached or semi-detached houses, according to the last census (2021). Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder. At about 47 miles from central London, Elsted Marsh sits inside the area we cover across London and the South East.

Your questions about air source heat pumps in Elsted Marsh
Is the heat pump grant available in Elsted Marsh?
Yes, if the home and the heat pump meet the scheme’s rules: Elsted Marsh is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Is Elsted Marsh within the area you cover?
Yes. Elsted Marsh 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 servicing affect my warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Keep every service record either way.
How much does an air source 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.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us in Elsted Marsh and across West Sussex. Let us know who the records should go to.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
How it works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it 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 plan the trip to Elsted Marsh around you.
- We talk through your home, your current heating and what you want from a heat pump.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.

Advice
Fixed-price quotes for air source heat pumps in Elsted Marsh
A fixed price needs a few facts first. We look at:
- Access, including height, roofs and ladders
- What kind of system it is
- The number of rooms, units or zones
Our prices page shows typical ranges, but each job is priced on what it involves. Call for a fixed-price quote, and we will talk you through it.
Asking for a quote
Photos and a few facts are often enough to price a simple job. Send what you can of the following:
- A short video of any fault, such as a noise or a flashing light
- The outside wall, roof or yard where the outdoor unit sits or would go
- Where the property is and what kind of building it is
Here’s what helps us quote: where the property is and what kind of building it is, a few photos, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, ring 07833 053749 or use the quote form.

What you can do yourself, and what needs us
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. 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 give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.
