Commercial Air Conditioning — Specialist Installers
From a single shop split to a multi-floor VRF system, we match businesses with vetted, F-Gas certified commercial air conditioning engineers across Surrey and the South of England — for installation, planned maintenance and compliance.
Cooling designed around how you trade
Every commercial space has a different load profile — a restaurant kitchen at 7pm is nothing like a dental surgery at 10am. Engineers in our network design for the way your premises actually work.
Offices
Comfort cooling and heating for open-plan floors and meeting rooms, with zone control so the corner office and the server cupboard stop fighting over one thermostat.
Shops & retail
Door-open trading, bright lighting and footfall generate serious heat. Ceiling cassettes keep the sales floor comfortable without eating wall space.
Restaurants & cafés
Dining rooms need quiet, draught-free comfort while kitchens dump heat next door. Zoned systems handle both without freezing the front of house.
Server & comms rooms
Close-control cooling that runs around the clock, with redundancy where downtime is unacceptable. The one room where air conditioning is genuinely mission-critical.
Surgeries & clinics
Stable temperatures and clean, filtered air for treatment rooms and waiting areas, with quiet indoor units patients barely notice.
Gyms & studios
High occupancy, high humidity, high expectations. Properly sized systems pull heat and moisture out fast enough to keep classes comfortable.
The commercial toolkit
VRF/VRV. Variable refrigerant flow systems run many indoor units — cassettes, wall units, concealed ducted units — from shared outdoor plant, modulating refrigerant to each room as needed. One circuit can cool a boardroom while heating a north-facing office, which makes VRF the default for whole floors and multi-tenant buildings; see our dedicated VRF / VRV systems guide for how they are sized and priced.
Ceiling cassettes. Flush-mounted in a suspended ceiling with four-way air throw, cassettes cover large open areas evenly with nothing on the walls. The standard choice for retail and open-plan offices.
Ducted air handling. Concealed units feed conditioned air through ductwork to grilles, keeping plant completely out of sight — right for restaurants, clinics and premises where aesthetics or hygiene rule out visible units.
Splits. For a single shop, office or server cupboard, a well-specified wall or ceiling split is often the fastest, most cost-effective answer, at close to domestic pricing.
Commercial installation costs
Commercial work is priced by capacity and scope. These 2026 benchmarks are the sanity-check to hold quotes against.
| Scope | Basis | 2026 cost |
|---|---|---|
| VRF/VRV system, installed | Per kW of cooling capacity | £350–£600 / kW |
| Office fit-out (typical comfort cooling) | Per m² of floor area | £150–£300 / m² |
| Single split (small unit or back office) | Per system, supplied and installed | £1,500–£3,000 |
| Planned maintenance | Per system per year, multi-visit | Quoted per site |
Indicative 2026 UK ranges compiled from commercial installer pricing; final quotes depend on capacity, plant location, ceiling type, controls and out-of-hours working.
The compliance picture
Commercial air conditioning carries legal obligations that domestic owners never meet. Three matter to almost every operator:
F-Gas record keeping. Businesses operating larger systems must have refrigerant leak checks carried out at set intervals, keep records of every check, repair and refrigerant movement, and use F-Gas certified engineers for all refrigerant work. The records are your evidence in an inspection — a good maintenance contract maintains them for you.
TM44 inspections. If your building's air conditioning exceeds 12 kW of cooling capacity, a TM44 energy inspection by an accredited assessor is a legal requirement, repeated at least every five years. Beyond compliance, the report frequently identifies control and efficiency improvements that repay their cost in energy savings.
EPC impact. The efficiency of installed cooling and heating plant feeds into the building's energy performance assessment. Modern, well-controlled heat-pump-based systems support the rating; obsolete plant undermines it — and this is no longer just paperwork. Minimum energy efficiency standards (MEES) already bar commercial landlords from granting or continuing a lease on space rated below EPC E, and the government has consulted on raising that threshold toward EPC B by 2030, so the cooling and heating plant you specify now can decide whether a building stays lettable. Efficient heat-pump-based systems with good controls are one of the more cost-effective ways to lift a commercial rating.
Maintenance contracts
Commercial systems earn their keep only while they run. Planned preventative maintenance contracts schedule two or more service visits per year per system, keep coils, filters and condensate systems clean through heavy use, and maintain the F-Gas and TM44 paperwork trail. Most contracts also carry priority callout — which is what you are really buying if a failed compressor means a closed dining room.
When you request quotes, tell us the number and type of units and how critical the cooling is to trading; we'll match you with commercial engineers who can take on both the plant and the paperwork.
Sources & methodology
- Cost benchmarks: 2026 UK commercial installer pricing — VRF/VRV ~£350–£600 per kW installed; office fit-outs ~£150–£300 per m².
- TM44: statutory energy inspections for air conditioning systems over 12 kW.
- F-Gas: leak-check and record-keeping obligations on operators; certification legally required for refrigerant handling.
