Air source heat pumps for homes and businesses in Greenwich
Hot water from an air-to-water system is stored in a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. The work covers underfloor heating, radiator systems and air-to-air heat pumps, and the jobs we see most are plans to switch to electric heating with a heat pump and replacing a combi boiler with a heat pump.
Terraced houses in a London area like Greenwich 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.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Homes in Greenwich and heat pumps
About 36% of homes in Greenwich and the neighbourhoods around it were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 64% of households live in flats, according to the last census (2021). In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. 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. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If you live near Maze Hill station, the survey compares air-to-water and air-to-air for your home before anything is quoted. Period properties close to St Mary's Church can suit a heat pump, though insulation and any heritage protection are checked first.
Greenwich is about 4 miles east of London, in Greater London. Whether you are in the middle of Greenwich or further out, we cover air source heat pumps, from small jobs to large ones. In Greater London alone we list 764 places and Greenwich is among them.
One of our recent jobs in Greenwich was on Greenwich High Road (SE10): installing a Mitsubishi Electric wall-mounted unit in the retail area and a second unit in the stockroom and office.

What happens on the day
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we have done. If a freeholder or agent needs to agree the work in Greenwich, we can send them the details.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by 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
- Clear access to the fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we’re working in
Getting a quote
Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Why act early in Greenwich
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. It’s a date to bear in mind when planning alongside your own plans for the property. If a lease or managing agent is involved in Greenwich, start the conversation early.
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re unsure, ring 07833 053749 or drop us a line for straight advice and a fixed price.

Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Avoid switching the heat pump on and off often
- Seal draughts where you can
- Check what your manufacturer’s warranty asks of you
Now and then in cold weather, the outdoor unit defrosts itself. It may give off steam or sound different for a few minutes, and that’s normal.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside, so keep it clear all year.
Greenwich questions
Is planning permission needed for a heat pump in Greenwich?
It comes down to the building and the spot chosen for the outdoor unit. A conservation area takes in the middle of Greenwich. 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 Greenwich council, which is typically the planning authority for Greenwich.
Can I have air conditioning in a flat in Greenwich?
Often, yes, but the lease and the freeholder typically have a say. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Can I get the Boiler Upgrade Scheme grant?
We check the scheme rules for your property before you go ahead. As the installer, we make the application where you qualify.
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 and F-Gas records kept where they apply.
Do you provide F-Gas records?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Will skipping a service affect the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Keep every service record either way.
Do you protect the property while you work?
Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
When it’s something else
Air source heat pumps cannot fix everything, and we’d rather say so up front. It will not put right:
- Promising eligibility for the Boiler Upgrade Scheme
- Any gas work on the existing boiler
- Formal advice on VAT for your situation
Not sure which it is? You can phone 07833 053749 or use the quote form and we will tell you honestly.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
