How we handle air source heat pumps in City of London
As an MCS certified installer, we fit air source heat pumps for homes in City of London. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We’ll explain which type fits your home and why. We are often asked to deal with not knowing whether a grant applies and moving away from fossil-fuel heating, on hot water cylinders, underfloor heating and radiator systems.
In a London area like City of London, 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 typically a cylinder, while an air-to-air system needs less space.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

What we do, step by step
If the system has to be off for part of the visit, we tell you before work begins, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. A note on parking and access helps us plan a visit to City of London.
- We start with your plans and the property.
- 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.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
How to prepare
- Move furniture away from the wall where we will be working
- Let us know if the building has a permit or sign-in process
- Have the make and model of any existing unit to hand
Ask for a quote
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from photos and measurements. Then you get a fixed price so you know the cost before we begin.

Aftercare tips
Aftercare is straightforward, and it makes the next visit easier:
- Let the heat pump run steadily, as set up at handover
- File the MCS certificate safely
- Leave indoor units unobstructed
Equipment warranties come from the manufacturer. We go through the conditions with you, including any servicing they ask for.
Keep the outdoor unit clear of leaves, plants and stored items. It needs good airflow to collect heat from outside so keep it unobstructed.
Common problems we fix in City of London
Air-to-air systems interest people who want cooling in summer as well as heating. They warm rooms directly through indoor units, and can cool them when it’s hot. Whether a grant applies depends on the scheme conditions.
These are the situations we see most often:
- An oil, LPG or gas boiler near the end of its life
- Comparing heat pump types
- Working out where a cylinder could go
Mansion House lies about 0.2 miles south-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
What your quote should include
- Whether they hold F-Gas company certification, not just individual qualifications
- Whether the quote is a fixed price
- Why the equipment they’re quoting suits the job
City of London: your questions answered
Can I have air conditioning in a flat in City of London?
Normally, yes, though leaseholders normally need the freeholder’s agreement. 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.
Do I need planning permission for a heat pump in City of London?
That depends on the building and where the outdoor unit goes. The centre of City of London is in the Guildhall Conservation Area. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with the planning department at the City of London Corporation, usually the authority for City of London first.
Which type of heat pump is right for my home?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. With air-to-air, hot water needs another source and the survey helps decide.
Do you work in City of London?
Yes. We work across Greater London, Surrey, Kent, East and West Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes City of London.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.

Air source heat pumps around City of London
Valuation Office Agency council tax records date about 40% of homes across City of London and its surrounding area to the post-war years, 1945 to 1972, and the last census (2021) found about 98% of households live in flats. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Flats are often harder for air-to-water systems, so we look at whether air-to-air suits better. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If your home is one of the older properties near St Olave Old Jewry, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

Hot water cylinders
An air-to-water heat pump heats hot water through a cylinder. Space for the cylinder is part of the survey particularly in homes with a combi boiler.
Heat loss surveys
The survey covers the building fabric and how air moves through it along with the room sizes.

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
