Air source heat pumps in Molesey
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. The work covers underfloor heating, homes heated by oil, LPG or gas and air-to-water heat pumps, and the jobs we see most are an oil, LPG or gas boiler near the end of its life and not knowing whether a grant applies.
If your home near Molesey has no mains gas, the grant can be bigger. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme, for an air source or ground source heat pump.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

How it works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. From there, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Send pictures of the space and the outside wall, and we can plan the work near Molesey.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Before we arrive
- Unlock any gate, garage or side passage we need
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Make sure we can reach the consumer unit or fuse board
Ask for a quote
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. After a look at the job, by photos or a survey, the price is fixed. To get going, ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Keeping the system healthy
A little care keeps the system in better shape. Our advice:
- Seal draughts where you can
- Know the servicing conditions in your warranty
- Don’t block radiators or indoor units with furniture
The warranty on the heat pump is the manufacturer’s, on its own terms. We explain the terms for your brand, including any servicing conditions.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.

Common questions in Molesey
Is Molesey within the area you cover?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Can I get the Boiler Upgrade Scheme grant in Molesey?
Yes, if the home and the heat pump meet the scheme’s rules: Molesey is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You do not apply yourself: the MCS certified installer does, which is us.
What does an air-to-water heat pump cost?
Air-to-water installations cost £8,000–£16,000 (0% VAT on homes), before the grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Can you set up regular servicing?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
When to call us in Molesey
Homes with electric heating sometimes look at heat pumps as an alternative. The survey tells you whether it’s practical and what’s involved along with whether any grant could apply.
What we are most often called about:
- Working out whether radiators need upsizing
- Questions about the Boiler Upgrade Scheme
- Checking whether planning permission is needed
Period properties close to Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first.
Before booking anyone
- Whether a new circuit is included and who certifies it
- What happens if the job turns out to be different on the day
- Whether the quote is a fixed price

Air source heat pumps in Molesey: the local picture
About 13 miles out from central London, Molesey is part of the South East area we work across. The East Molesey Old Village Conservation Area lies close to the centre of Molesey, within about a third of a mile. There are 8 conservation areas within a mile of the centre of Molesey. On the National Heritage List, around 16 entries fall within 0.5 miles of the middle of Molesey; Park House (grade II) is one. 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 Elmbridge council, which usually handles Molesey.
If you live near Hampton Court station, the survey compares air-to-water and air-to-air for your home before anything is quoted.
