What affects the cost of air source heat pumps
We quote each job individually. This is what makes a difference:
- The condition of any existing system
- The brand, model and parts involved
- How many units are involved
The price reflects the work, not guesswork. That’s why every job is looked at first, and why the quote is fixed before we start.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- A short video of any fault, such as a noise or a flashing light
- Your consumer unit or fuse board
- The outdoor side of the property, including any roof or flat area
To help us quote: the address and the type of property, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Once you have those, call us on 07833 053749 or write to us at info@aircondoctor.co.uk.
Air source heat pumps in Loyter's Green, done properly
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. With air-to-air, hot water has to come from something else. We’re often asked to deal with a boiler that’s getting old and plans to switch to electric heating with a heat pump, on air-to-water heat pumps, air-to-air heat pumps and homes heated by oil, LPG or gas.
In a place like Loyter's Green, some homes are listed, because permitted development doesn’t apply within the grounds of a listed building, so consent comes first.
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.

Loyter's Green: your questions answered
Do you cover smaller places like Loyter's Green?
Yes, and the size of the place makes no difference to how we work. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Is the heat pump grant available in Loyter's Green?
Yes, the scheme covers homes in England, including Loyter's Green, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
What’s the difference between air-to-water and air-to-air heat pumps?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases. We explain the options after the survey.
What accreditations do you have?
We are an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are also Checkatrade members.
Why use an F-Gas certified company?
Companies working on equipment that contains F gas must be certified by an approved body, and each engineer needs the right qualifications too. It means the refrigerant in your system is handled legally.
Do you work on systems someone else installed?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.

What owners can safely do
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Air source heat pumps in Loyter's Green: the local picture
White Cottage, listed at grade II, is one of roughly 7 protected buildings and structures in the half-mile around Loyter's Green’s centre. 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 local planning authority (normally Epping Forest council). About 22 miles out from central London, Loyter's Green is part of the South East area we work across.
A heat loss calculation decides the size of heat pump your home needs. Live in one of the older houses around Parish Church of St Mary Magdalen? Expect the survey to look closely at heat loss and at the building’s planning status.

How the visit works
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we’ve done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work 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. Rural lanes and tight entrances are worth mentioning before a visit to Loyter's Green.

Getting a price
Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by photos or a survey, the price is fixed. To get going, call 07833 053749 or drop us a line.

Rented and managed buildings
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we are happy to deal with whoever it is.
Facilities teams in offices, schools and public buildings book us too in Loyter's Green and across Essex. Work can be phased by floor, zone or building to keep disruption down.
