What we do, step by step
Where something has to be switched off during the work, we agree it with you first so it doesn’t catch you out. For businesses, we can typically work room by room or zone by zone. The work takes about a day for a single-room system, longer for multi-room and ducted systems. Send us a few phone pictures and we can often price a straightforward job in Petersham before visiting.
- We survey the rooms and the outside of the property, or work from photos and details for simple jobs.
- You receive one fixed figure covering the kit, the fitting and the positions we agreed.
- Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
- Once the electrics are connected, the pipework is tested for leaks and put under vacuum before any refrigerant flows.
- Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Unlock any gate, garage or side passage we need
- Let us know where we can park and unload

Advice
About our air conditioning in Petersham
Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see and we talk you through it on the survey. Every installation in Petersham begins with a look at the rooms, the walls and where the outdoor unit can go, then a fixed-price quote that names the make and model.
The electrics are part of the job: a dedicated circuit where the unit needs one, certified under NICEIC, so the electrical paperwork comes with the installation.
In Petersham, as across London, the rooms that get hottest are usually under the roof or behind large sunny windows. A single wall-mounted unit in the worst room is often where people start, and a multi-split can cover more rooms from one outdoor unit where space outside is short.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

FAQs for Petersham
Is air conditioning in Petersham permitted development?
It comes down to the building and the spot chosen for the outdoor unit. The centre of Petersham is in the Petersham Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Petersham, normally Richmond-Upon-Thames council).
Is Petersham in your area for air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Petersham is part of that. Just give us a ring on 07833 053749 or email us with a few details.
Can air conditioning heat my home as well?
Usually, yes. A heat pump moves heat from the outside air into the room, so it gives out more heat than the electricity it uses. If you want it to replace your main heating, ask about air-to-air heat pumps and the conditions for the Boiler Upgrade Scheme grant.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone and we’ll gladly show you ours.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.
Which type of air conditioning is best?
There’s no single best type. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. The survey ends with a recommendation and the reasons.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Air conditioning around Petersham
Valuation Office Agency council tax records put about 48% of homes in the Petersham area before 1919, and the 2021 Census found about 50% of households live in flats. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. In flats, the lease and the freeholder usually decide where an outdoor unit can go, and the permitted development rules for flats are tighter. London installs often hinge on outside space, the lease and access to the building.
With historic houses such as Pembroke Lodge about 0.5 miles south-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Before you call an engineer
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We are happy to deal with either side and send the records to whoever needs them.
Do you need air conditioning in Petersham?
Many people try a portable unit first. A portable unit has to vent its warm air through a hose out of a window, which lets some heat back in, and its compressor sits in the room with you. With a split system, the compressor lives outside.
Look out for these signs:
- A room that’s unbearable on warm days
- A loft conversion that is too warm to use
- Old electric heaters you’d like to replace with something more efficient
If your home is in one of the older streets near St Peter's Church, it’s worth checking whether it’s listed or in a conservation area before an install.
