How we handle air source heat pumps in Merton Park
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. Please treat this as general information rather than tax advice. The work covers air-to-air heat pumps, air-to-water heat pumps and underfloor heating, and common reasons people get in touch are questions about where the outdoor unit can go and not knowing whether a grant applies.
In a London area like Merton Park, many homes are flats or terraces with little outside space, and that decides which kind of heat pump works. Air-to-water needs room for the outdoor unit and usually a cylinder, while an air-to-air system needs less space.
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.

Common questions in Merton Park
Is the heat pump grant available in Merton Park?
Yes, the scheme covers homes in England, including Merton Park, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we are MCS certified.
Do I need permission to put air conditioning in my flat in Merton Park?
Usually, yes, though leaseholders normally need the freeholder’s agreement. 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.
How long does a heat pump installation take?
A typical installation takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The programme is planned to keep time without heating short, and we explain it in advance.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Can you come out in an emergency?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll talk you through the next steps.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Safe owner checks
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. A suspected leak is our job, not yours.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
When it’s something else
We’ll always give you a straight diagnosis, so here’s what air source heat pumps won’t do:
- Getting planning permission or listed building consent on your behalf
- Grants for hybrid systems or replacements of low-carbon systems
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
If you are not sure, just phone 07833 053749, or email if that’s easier and we’ll give you a straight answer.

The process
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit 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. Photos of the room and where the outdoor unit could go let us plan most of a visit to Merton Park in advance.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We recommend air-to-water or air-to-air and check the grant position.
- The system is installed and connected to the controls.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Move furniture away from the wall where we will be working
- Tell us about parking and loading
- Find the manual or the paperwork for the system, if you have it

Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger so we check them against each room’s heat loss.
Air-to-water heat pumps
An air-to-water heat pump heats water for your radiators or underfloor heating and your hot water cylinder. It takes over from the boiler and we install it to MCS standards.
Air source heat pumps in Merton Park: the local picture
VOA council tax data put about 47% of homes in Merton Park and the neighbourhoods around it before 1919. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Homeowners near South Merton station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that. With Southside House about 1.4 miles west, it’s worth asking whether your own home is listed before planning a heat pump.
