In a London area like Herne Hill, many of the homes we are asked about are flats, maisonettes and terraced houses. That shapes the job: where the outdoor unit can go, how the pipework reaches it and who needs to agree first. In a flat, the lease and the freeholder normally come into it, and we can give you the details they’ll ask for.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

What an install looks like in Herne Hill
About 59% of homes in and around Herne Hill were built before 1919, according to VOA council tax data, and the last census (2021) found about 57% of households live in flats. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. In flats, the lease and the freeholder typically decide where an outdoor unit can go, and the permitted development rules for flats are tighter. In London, outdoor unit positions, building rules and access tend to need more planning than the install itself.
Living close to Saint Faith's? Some older properties in parts like that are protected, and the survey finds out whether yours is. With historic houses such as Kingswood House about 1.7 miles south, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Honest limits
It’s worth knowing the limits before booking:
- A lack of fresh air (most split systems recirculate room air rather than bringing fresh air in, which is a job for ventilation)
- Problems with a gas boiler or the radiators
- A room that can’t take an outdoor unit or pipe route without the landlord’s, management company’s or council’s consent (that consent comes first)
If you are not sure, just ring us on 07833 053749, or email if that’s easier and we will give you a straight answer before you book.

The process
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. All told, the work takes anything from a day for one room to several days for a multi-room or ducted system. Photos of the room and where the outdoor unit could go let us plan most of a visit to Herne Hill in advance.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Then the prescription: the right system and size for each room, on a fixed-price quote.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Checks: a pressure test for leaks, then a vacuum to clear moisture.
- The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.
Getting ready for the visit
- Mention any managing agent or landlord rules we need to follow
- Keep pets and children away from the work area
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a price
Quoting starts with a diagnosis, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.

What affects the cost of air conditioning
You will get a fixed price before we start. It takes into account:
- What electrical work the job needs
- The number of rooms, units or zones
- Which make and model is being fitted or worked on
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all play a part.
Helping us quote
To speed up the quote, please include:
- Photos showing the indoor unit and the space around it
- The fuse board and where it is in the property
- The rating plate or label on any existing unit
To get a fixed-price quote, phone 07833 053749, or email if that’s easier and tell us about the property and what you need. A few photos make it quicker. You will hear back from us the same working day.
Managing agents and facilities teams in Herne Hill
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
FAQs for Herne Hill
Is planning permission needed for air conditioning in Herne Hill?
The answer turns on the property and where the outdoor unit would sit. Central Herne Hill is a short walk from the Sunray Estate Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Southwark council, usually the authority for Herne Hill.
Can I have air conditioning in a flat in Herne Hill?
In many cases, yes, once the lease and the building’s rules are checked. 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.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
What does it cost to install air conditioning?
From £1,200 + VAT for a single-room split, with a typical range of £1,200–£2,200 + VAT. That covers supply, installation, commissioning and the F-Gas paperwork, and we fix it after a survey or from your photos.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
