Air Source Heat Pumps in New Malden
Looking for air source heat pumps in New Malden? We look at the job first, give you a fixed-price quote and do the work at a time that suits you, finishing with proper records.

After we have gone
Systems last better with the right care. Here’s what we suggest:
- Clear leaves and debris from the outdoor unit
- Avoid switching the heat pump on and off often
- Read the manufacturer’s warranty terms for your brand
If anything does not seem right after installation, ring us on 07833 053749 or use the quote form and we’ll look into it. Annual servicing helps keep the system working well.
Let the heat pump run steadily rather than switching it on and off as explained at handover.
Air source heat pumps in New Malden
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. The work covers underfloor heating, air-to-water heat pumps and air-to-air heat pumps, and common reasons people get in touch are questions about listed buildings or conservation areas and plans to switch to electric heating with a heat pump.
For flats in New Malden, the lease, the freeholder and the rules for flats all come into it. The planning rules for flats are stricter than for houses, and we check before designing.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Common questions in New Malden
Is the heat pump grant available in New Malden?
Yes, if the home and the heat pump meet the scheme’s rules: New Malden 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. We hold MCS certification, so the application is ours to make for you.
Can I have air conditioning in a flat in New Malden?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do you work in New Malden?
Yes. New Malden is part of the area we cover, as part of our area across London and the South East. We’re based in East Grinstead, West Sussex.
Are my radiators big enough for a heat pump?
It varies from room to room. We check them all during the survey, so the quote covers any changes.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
What does F-Gas certified mean?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and AirCon Doctor is certified.
When something else is needed
Air source heat pumps cannot fix everything, and we’ll tell you before any work starts. It doesn’t solve:
- Planning approval where permitted development does not apply
- Tax advice on your own circumstances
- Disconnecting or servicing a gas boiler
If you are not sure, just phone us on 07833 053749 or use the quote form and we will give you a straight answer before you book.

Air source heat pumps around New Malden
About 40% of homes in the New Malden area were built between the wars, according to Valuation Office Agency council tax records. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. In London, outside space and the rules for flats often decide which kind of heat pump suits.

Leave it or put it right?
Choosing between air-to-water and air-to-air is easier with the facts. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions, and we explain which fits your home. Approvals for flats in New Malden can take longer than the install itself.
