Heat pump
NW1
Camden
Samsung monobloc air source heat pump
Levelled on packers on an existing tiled patio rather than bolted through it, so the tiling stays intact and the unit still sits dead flat.

Tottenham
Air source heat pump with solar and battery storage
The whole electrical side on one wall: inverter, battery modules and every isolator in reach, with the conduit dressed in straight runs so a fault years from now can be traced without stripping the wall.

Heat pump
E11
Leytonstone
Samsung monobloc air source heat pump
On its own slab set clear of the fence line, with the condensate taken away below ground level instead of being left to run across the paving and freeze.

N22
Wood Green
Samsung monobloc air source heat pump
Stood on a levelled base built up out of the border rather than on soil, so the feet stay out of standing water and the unit does not settle out of level over a winter.

Air conditioning
N11
New Southgate
Daikin multi-split condenser
Wall-mounted on brackets rather than stood on the ground, which is usually what a narrow side return leaves you, and the refrigerant lines dropped in a single trunked run.

Heat pump
N12
North Finchley
Samsung air source heat pump with hydrobox
Heat pump and hydrobox both outside in the side passage, which keeps the whole system out of the house and leaves the cupboard the old boiler used.

Heat pump and solar
N21
Winchmore Hill
Air source heat pump with roof-mounted solar
The panels sit across the rear pitch and the heat pump at the side of the house, which is the pairing that lets the pump run on its own generation through the middle of the day.

Mitsubishi Ecodan air source heat pump
An Ecodan stood off the boundary fence far enough that the fan discharge is not bouncing straight back off it, which is what makes a badly sited unit sound louder than it is.

Air conditioning installation in City of London costs 2,400 to 3,200 pounds for a single room, fitted and including VAT, and takes one day on site.
On a listed estate like the Barbican, the question is not what fits but what the estate's own guidance and the listing allow. We read that first and tell you honestly, and sometimes the answer is a unit with no outdoor part at all.

The housing stock in City of London, and what it means for the job
Fewer than five thousand households live in the City, and 98 per cent of them are flats. The largest share is the Barbican and the Golden Lane estate, both listed, where any change to the outside of a building is a listed building consent question before it is an engineering one. The rest is newer residential towers and conversions of older commercial buildings. So most of our work in the square mile is not domestic at all: it is offices, server and comms rooms, restaurants and shops, fitted out of hours so the floor keeps trading.
The typical City of London installation
A typical City job is an office floor or a meeting room on ceiling cassettes, fitted overnight or at a weekend, with the plant position agreed with the landlord's managing agent first.

Permission in City of London
Conservation area coverage in City of London is high, so the first check on any address here is whether the street sits inside one. Inside a conservation area you keep permitted development rights, but the outdoor unit cannot go on a wall or roof slope fronting a highway, which in practice means the rear. Where the property is a flat, planning permission is needed regardless of any of that. Your street, any Article 4 direction and the listed building register are the first three things we check, and the answer is in writing before you pay anything.
What the housing in City of London means for permission
City of London is a borough of flats: 98 per cent of homes, against 2 per cent houses. 87 per cent of all homes here are in purpose-built blocks, which in practice means a managing agent, a licence for alterations and a consent pack before anybody talks about dates. Nothing about that is unusual and none of it is quick. If you own a house here you are in the 2 per cent, and your job is the straightforward kind. The most common home in City of London is a flat in a purpose-built block, 87 per cent, which usually means a managing agent, a licence for alterations and a plant position the building decides. Of the 21 boroughs we cover north of the Thames, City of London has the lowest share of houses.
| Home type | Share of City of London | What it means here |
|---|---|---|
| Detached | 0% | Almost none here |
| Semi-detached | 0% | Almost none here |
| Terraced | 2% | Very few here |
| Purpose-built flat | 87% | A large share here. Planning permission and freeholder consent, both |
| Converted flat | 7% | Two permissions, usually a smaller freeholder |
Shares of the 4,914 households counted in City of London at the 2021 Census, table TS044, rounded. Percentages do not total 100 because homes in commercial buildings and temporary structures are counted separately.

Air conditioning in City of London: common questions
How much does air conditioning cost in City of London?
2,400 to 3,200 pounds for a single room, with nothing added for the zone, and commercial floors are priced from a heat load calculation rather than from a band. A two-room system on one outdoor unit is typically 4,300 to 5,800 pounds, and three rooms 6,400 to 8,600 pounds.
Every price includes the units, installation, commissioning, electrical work and VAT. The fixed price comes after a free survey. There is a full breakdown on the cost page.
Do I need planning permission for air conditioning in City of London?
It depends on which of the two you have. 98 per cent of homes in City of London are flats, and a flat always needs planning permission for this work.
The section further down this page sets out what the housing stock here means in practice, and every condition is on the planning permission page. We check the conservation area boundary, any Article 4 direction and the listed building register for your exact address before quoting.
How quickly can you get to City of London?
Thirty five to fifty minutes from N14. The City is inside the congestion charge zone, which we pay rather than pass on, and loading is agreed with building management before the day. For a survey we usually offer something within 48 hours, and for a fault call we will tell you the day we can genuinely attend rather than promising one we cannot keep.
Do you install in flats in City of London?
Yes. 98 per cent of homes in City of London are flats, 87 per cent of them purpose-built and 7 per cent conversions, so it is a large share of what we do here. It takes two permissions rather than one: the freeholder's written consent and planning permission from the council.
We prepare the licence pack the managing agent will ask for at no charge, including the drawing, the sound data and the insurance. The order the two permissions are done in is what decides whether it is expensive, and there is a full sequence on the leasehold flats page.
Do you service and repair existing systems in City of London?
Yes, any make and any age, including systems installed by companies no longer trading. An annual service is 95 pounds plus VAT and a fault diagnosis is 89 pounds plus VAT, waived if we do the repair the same day. See servicing and repairs.
