How we price air source heat pumps
The price is fixed before any work begins. It’s based on:
- The electrical supply and whether a new circuit is needed
- Which make and model is being fitted or worked on
- What we find on the survey or diagnosis
No two properties are the same, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all play a part.
What we need to know
There’s no need for technical detail. Just send:
- The outside wall, roof or yard where the outdoor unit sits or would go
- A close-up of the unit’s label showing the model number
- Wide pictures of the room or the existing unit
Here’s what helps us quote: the address and the type of property, photos of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Once you have those, give us a ring on 07833 053749 or fill in the contact form.
About our air source heat pumps in Nalderswood
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. 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 a boiler that’s getting old, on underfloor heating, air-to-water heat pumps and hot water cylinders.
Space for an outdoor unit is rarely an issue near Nalderswood, so the design focuses on heat loss and radiators.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Safe owner checks
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
System by system
Outdoor unit position and planning
Flats have tighter limits, and an Article 4 direction can remove permitted development rights. Listed building consent is a separate matter, and we check the position for your property.
Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. A £7,500 grant may be available through the Boiler Upgrade Scheme for eligible homes, and we apply for it as the installer.
Nalderswood questions
Do you cover smaller places like Nalderswood?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will a heat pump in Nalderswood need planning permission?
The answer turns on the property and where the outdoor unit would sit. Around 5 listed entries sit within 0.5 miles of central Nalderswood. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the planning department at Mole Valley council, normally the authority for Nalderswood.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning and we explain the terms for your brand on the quote.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and explain why.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
What a heat pump looks like in Nalderswood
About 72% of households live in detached or semi-detached houses, according to the last census (2021). Houses usually have space for an outdoor unit and a hot water cylinder.
A heat loss calculation decides the size of heat pump your home needs. Period properties close to Church of St Bartholomew can suit a heat pump, though insulation and any heritage protection are checked first.

The process
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site 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, and we clear up before we go. Visits to Nalderswood are agreed with you in advance and planned so the job can be finished in one trip where possible.

Getting ready for the visit
