About our air source heat pumps in Morden
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it does not apply to businesses, and for air-to-air systems we confirm the VAT on your quote. Please treat this as general information rather than tax advice. The work covers air-to-air heat pumps, homes heated by oil, LPG or gas and radiator systems, and the jobs we see most are ageing boilers that will need replacing and checking whether planning permission is needed.
Homes in Morden are often flats and terraces, where outside space is limited, and that decides which kind of heat pump works. Air-to-water needs room for the outdoor unit and usually a cylinder, while air-to-air units take less room.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

What happens on the day
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. The visit takes from a couple of days to around a week, depending on the system and how much of the heating changes. Parking bays, permits and roof or balcony access are the first things we ask about in Morden.
- It starts with a conversation about the home, the existing heating and your plans.
- 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.
- You get a fixed-price quote, with any grant you’re eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
How to prepare
- Mention any roof access, ladders or high-level work
- Have the make and model of any existing unit to hand
- Clear the space around the indoor unit, or where it will go
Getting a price
For air source heat pumps in Morden, call us on 07833 053749, or email if that’s easier. Tell us what kind of property it is and what you’d like done, and send a few photos if you can. Enquiries get a reply the same working day.
Advice
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- Leave indoor units unobstructed
- Let the heat pump run steadily, as set up at handover
- Find out the grant position at the survey
Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts so we set the controls up with you.
Keep insulation and draught-proofing in good order, as lower heat loss means the system has less to do.
Morden questions
Is a heat pump in Morden permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Central Morden sits inside the Upper Morden Conservation Area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Merton council, which is typically the planning authority for Morden.
Can I have air conditioning in a flat in Morden?
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 on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us in Morden and across Greater London. Let us know who the records should go to.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
Which brands do you work with?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
How long will it take to install a heat pump?
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. The survey lets us set a firm programme, and you can phone us on 07833 053749 or drop us a line to book it.
Can I get the Boiler Upgrade Scheme grant?
We confirm eligibility at the survey stage. There’s one grant per property, you can’t get one to replace a low-carbon system, and hybrids are excluded and other conditions apply.
Air source heat pumps in Morden: the local picture
The Valuation Office Agency’s council tax figures show about 84% of homes across Morden and its surrounding area date from 1919 to 1939, and about 53% of households live in terraced houses, according to the last census (2021). Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door. For a London home, the outdoor unit position and the MCS noise check need careful planning.
For a home near St Helier station, the survey looks at whether an air-to-water or air-to-air heat pump suits better.

System by system
Air-to-air heat pumps
The £2,500 grant for air-to-air applies only when the system replaces the fossil-fuel heating and covers the whole home’s demand. It must be installed by an MCS certified installer and be in a home.
Hot water cylinders
An older cylinder may not suit a heat pump, and we explain whether yours can stay.

Common problems we fix in Morden
Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. The Boiler Upgrade Scheme includes an extra £1,500, until March 2027, for air source or ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.
Reasons to give us a call include:
- Ageing boilers that will need replacing
- Moving away from fossil-fuel heating
- Checking whether planning permission is needed
Older homes near St Lawrence Church may need extra checks for planning and heat loss before a heat pump is designed.

“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
