Commercial air conditioning for homes and businesses in Hamsey
Once a system is in, it needs looking after. Maintenance contracts cover servicing, F-gas leak checks and the records that go with them, at a price fixed with your quote. Our 24/7 emergency line is there if something goes wrong. The work covers ceiling cassettes, VRF systems and server and comms room cooling, and common reasons people get in touch are leak check schedules that have slipped and work raised by a TM44 inspection.
For a hall or similar building near Hamsey, an air-to-air system that responds quickly suits intermittent use.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Managing agents and facilities teams in Hamsey
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
Managing agents often deal with us directly. Tell us the property, the work and the access arrangements and we will come back with a fixed-price quote.
What happens on the day
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone, and we tidy up before we leave. Seeing the property in photos first means the trip to Hamsey can be planned properly.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- Installation is scheduled to fit the business, with out-of-hours and phased work where necessary.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
Before we arrive
- Mention any managing agent or landlord rules we need to follow
- Let us know if the units are on a roof, a high wall or in a locked area
- Clear access to the fuse board
Ask for a quote
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price before any work starts.

Common questions in Hamsey
Do you cover smaller places like Hamsey?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Is Hamsey in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Hamsey is part of that. Just phone 07833 053749, or email if that’s easier with a few details.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule and quote for it. Leak checks required by the F-gas rules can be built in for larger systems.
Does my building need a TM44 inspection?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. The inspection is done by an accredited assessor, and we do the follow-up work.
Will I get records for the system?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
Is planning permission needed for the outdoor unit?
That depends on what’s being fitted and where. In England, an air source heat pump on a house can be permitted development if it meets set conditions, including the MCS 020(a) noise check, but a cooling-only unit is not covered, so check with the council. Listed buildings, conservation areas and flats have extra limits. This is general information, not legal advice.
What’s the price of air conditioning for a business?
After a site survey, with a fixed-price quote. Factors include the number of areas, the system type, access and any out-of-hours or phased work.
Why act early in Hamsey
A well-planned programme lets the building stay open while the work goes on. Waiting for a failure removes that choice. Booking before summer means the work in Hamsey is done before the hot weather.
Our prices page shows typical ranges, but your price depends on the job in front of us. For a fixed-price quote, call 07833 053749 or drop us a line, and we’ll explain what it covers.

System by system
F-gas records and TM44
An accredited energy assessor carries out the TM44 inspection. We don’t inspect, but we get systems ready and do the follow-up work.
Ducted systems
A ducted system hides the indoor unit and feeds air to the room through grilles. They’re chosen where appearance matters, such as hotels, restaurants and shops.
Business air conditioning in Hamsey
Food Standards Agency records list about 5 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of Hamsey. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. In the mile around Hamsey’s centre, 2 conservation areas have been designated. Historic England lists about 6 buildings and structures within half a mile of the centre of Hamsey, including The Parish Church of St Peter (grade I). That matters for air conditioning: permitted development does not apply within the grounds of a listed building, in a conservation area the outdoor unit can’t go on a wall or roof facing a road, and a unit used only for cooling is not covered at all, so we check with Lewes council, typically the planning authority here where necessary. About 37% of households live in terraced houses, according to the last census (2021). Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care.
If you run a surgery, clinic or pharmacy in the area around Lewes Victoria Hospital, about 1.5 miles south, cleanable, quiet units and regular maintenance matter. For a church or hall like The Parish Church of St Peter, any outdoor unit needs the right consents first.
