About our air source heat pumps in Merton Abbey
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation and the installer makes the application. Not every home qualifies, so we check eligibility before you commit. The work covers hot water cylinders, underfloor heating and air-to-water heat pumps, and the jobs we see most are working out where a cylinder could go and checking whether planning permission is needed.
Terraced houses in a London area like Merton Abbey can suit a heat pump well, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
Think of the paperwork as the 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 and it’s worth keeping safe.

Advice
How the job changes from property to property
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. A unit used solely for cooling is not covered and need a check with the council.
Outdoor unit position and planning
The outdoor unit needs a position with good airflow, a solid base and a sensible pipe route. We also consider neighbours and noise, as MCS 020(a) includes a noise check.
Questions from Merton Abbey
Is the heat pump grant available in Merton Abbey?
Yes, if the home and the heat pump meet the scheme’s rules: Merton Abbey 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. As an MCS certified installer, we apply for it on your behalf.
Is a heat pump in Merton Abbey permitted development?
It depends on the property. Central Merton Abbey is a short walk from the Wandle Valley 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 don’t 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 usually the planning authority for Merton Abbey.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
How does the warranty work?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are members of Checkatrade too.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Is Merton Abbey in your area?
Yes. Our area takes in London and the counties of the South East, and that includes Merton Abbey.
Signs you need air source heat pumps in Merton Abbey
Some people want to move away from burning fossil fuels at home. With a heat pump, the heat comes from the air outside and the system runs on electricity, which is why it fits that aim.
What we’re most often called about:
- Plans to switch to electric heating with a heat pump
- Questions about where the outdoor unit can go
- Replacing a combi boiler with a heat pump
Homeowners near Haydons Road station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
What your quote should include
- Whether the price is fixed or an estimate
- Why the equipment they’re quoting suits the job
- If the quote is based on a survey, photos or a diagnosis
Homes in Merton Abbey and heat pumps
Census 2021 figures found about 54% of households live in flats. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
With Southside House about 2.2 miles west, it’s worth asking whether your own home is listed before planning a heat pump.

What owners can safely do
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
