Air source heat pumps for homes and businesses in Marylebone
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. If you’re dealing with working out where a cylinder could go and questions about where the outdoor unit can go, we can help.
In a London area like Marylebone, many homes are flats or terraces with little outside space, which affects which heat pump suits. Air-to-water needs room for the outdoor unit and normally a cylinder, while air-to-air units take less room.
Whatever the visit, you get a written record: 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 a heat pump looks like in Marylebone
About 50% of homes across Marylebone and its surrounding area were built before 1919, according to VOA council tax data, and about 92% of households live in flats, according to the 2021 Census. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. In flats, space for an outdoor unit and a cylinder can be limited, and the lease and freeholder come into it, so air-to-air is sometimes the better fit. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Historic houses such as Handel Hendrix House, about 0.3 miles south, are a reminder that listed homes need consent before a heat pump goes in. If you live near Bond Street station, the survey compares air-to-water and air-to-air for your home before anything is quoted.

The Boiler Upgrade Scheme
In England and Wales, the Boiler Upgrade Scheme offers grants towards heat pumps: £7,500 for air-to-water and ground source, and £2,500 for air-to-air in limited cases. The application goes through the installer.
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. Cooling-only units are not included, so check with the council.

Marylebone: your questions answered
Will a heat pump in Marylebone need planning permission?
That depends on the building and where the outdoor unit goes. Central Marylebone sits inside the Harley Street Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with Westminster council, which is usually the planning authority for Marylebone.
Does the Boiler Upgrade Scheme cover homes in Marylebone?
Yes, the scheme covers homes in England, including Marylebone, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. As an MCS certified installer, we apply for it on your behalf.
How much time does a heat pump install need?
A typical installation takes a few days for most air-to-water installations, with air-to-air systems often quicker. We plan the work so you are without heating for as little time as possible and agreed before any work starts.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Can you set up regular servicing?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
How does the warranty work?
It’s the manufacturer’s warranty, which varies by brand. Daikin, for instance, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Will my radiators work with a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
What happens on the day
Wherever the system can be run before we leave, we run it and check it in operation. Then we explain what was done and answer your questions, and anything that needs attention later is pointed out. All told, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Before a visit in Marylebone, we ask where the van can stop and how we reach the outdoor unit.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- We install, commission and register the system under MCS.
Before we arrive
- Find the manual or the paperwork for the system, if you have it
- Keep pets and children away from the work area
- Mention any roof access, ladders or high-level work
