Air conditioning installation in Greenhill
Most air conditioning needs its own electrical supply from the consumer unit. Adding a new circuit is notifiable building work under Part P unless it’s done by a registered competent person, and as NICEIC approved contractors we can install and certify it as part of the job. Looking for air con installers near Greenhill? AirCon Doctor works across London and the South East from East Grinstead, as an F-Gas certified company with NICEIC approval.
Where the outdoor unit goes decides how quiet and tidy the job is: we balance airflow, noise, the pipe run and access for future servicing.
Space outside is often tight in Greenhill, as in much of London, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. Neighbours’ windows and noise matter as much as appearance when we choose the position, and we plan the pipe route so it’s as short and tidy as the building allows.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Homes in Greenhill and air conditioning
VOA council tax data put about 65% of homes in the Greenhill area before 1919, and about 80% of households live in flats, according to the last census (2021). Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.

Greenhill questions
Do I need permission to put air conditioning in my flat in Greenhill?
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.
Is Greenhill in your area for air conditioning?
Yes. Greenhill is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before work begins, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do you look at the job first?
Yes. We always look before we price, on a survey, or from your pictures and details where the job is simple. A fixed-price quote follows.
Does air conditioning need its own electrical supply?
Normally, yes. We check your consumer unit on the survey and include any electrical work on the quote and we install and certify the circuit as NICEIC approved contractors.
Can I use air conditioning to heat a room?
Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. We confirm the heating function of the model we quote.
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. The price includes supply, installation, commissioning and F-Gas documentation, and we fix it after a survey or from your photos.
Let and managed properties
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. Where a building is let or managed, the lease or contract should make clear who looks after the system and we’re happy to deal with whoever it is.
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork, and we will keep everyone informed.

What happens on the day
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then the work itself, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, and that 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 Greenhill in advance.
- We survey the property, or work from your pictures for a simple job.

Advice
What we’re called out for in Greenhill
Not everyone is after cooling. Old direct electric heaters turn electricity straight into heat, while a heat pump moves heat in from the outside air, which means more heat out than electricity in. That’s how most modern split systems work.
If any of these sounds familiar, it’s worth a diagnosis:
- A home office that warms up with screens and equipment
- A system on old refrigerant that’s due for replacement
- A loft conversion that is too warm to use
With historic houses such as 2 Willow Road about 0.3 miles north-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

“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.”
