Commercial Kitchen Air Conditioning Cost UK
A professional kitchen is the hottest room on almost any site, and cooling one properly costs more per square metre than any other commercial space — from around £3,000 for a small takeaway kitchen up to £25,000 or more for a hotel or production kitchen. The reason is simple: you're fighting ovens, fryers and a canopy that pulls your conditioned air straight back out. Here's what it costs in 2026, how kitchens are sized, and why the cooling has to work with your extract rather than against it.
How much does commercial kitchen air conditioning cost?
Budget around £3,000–£6,000 for a small café or takeaway kitchen, £6,000–£12,000 for a mid-size restaurant kitchen, and £12,000–£25,000+ for a large hotel, school or production kitchen that needs tempered make-up air on top of comfort cooling. Kitchens work out dearer per kW than a dining room because the heat load is so much higher and the units have to shrug off grease and high temperatures. These are feasibility budgets, not quotes — real pricing follows a heat-load survey that accounts for your appliances and your extract. Air Con Surrey is a free matching service: we connect you with vetted, F-Gas certified commercial engineers who survey the kitchen and quote properly.
Commercial kitchen cooling costs by size
Indicative supplied-and-installed prices for the cooling, excluding VAT. Capacity is a starting point only — the appliance line-up and how much conditioned air your canopy extracts shift these numbers a lot.
| Kitchen | Typical system | Approx. capacity | Indicative cost |
|---|---|---|---|
| Small café / takeaway kitchen (1–2 cooking stations) | Grease-rated ceiling cassette or high-wall unit | ~7–10 kW | £3,000–£6,000 |
| Mid-size restaurant kitchen (30–60 covers) | Multi-split cassettes, zoned off the line | ~12–20 kW | £6,000–£12,000 |
| Large hotel / school / production kitchen | VRF plus tempered make-up air handling | 25 kW+ | £12,000–£25,000+ |
| Dark / ghost kitchen unit (sealed shell) | High-capacity sealed system, close control | varies | from £4,000 |
Indicative UK 2026 installer quote data, supplied and installed, excluding VAT. Cooling a kitchen is priced alongside — not instead of — its extract and make-up air ventilation. For front-of-house pricing see the restaurant air conditioning cost guide, or the wider commercial air conditioning cost guide for offices, shops and server rooms.
Why kitchens need so much more cooling
A dining room is sized at roughly 100 W of cooling per m². A working kitchen can need three to five times that once you count the ovens, grills, fryers, pass lamps and dishwasher — and the load peaks during service, exactly when the room is fullest. The other half of the problem is ventilation. The extract canopy over the cooking line shifts huge volumes of air to clear heat, steam and grease, and every cubic metre it removes has to be replaced by make-up air coming in. If that incoming air isn't tempered, your comfort units end up cooling the street. Good kitchen design treats cooling, extract and make-up air as one system, which is why a survey counts for more here than almost anywhere else. The chart gives a feel for how the load compares.
Picking cooling that survives a kitchen
The kit that keeps an office comfortable will struggle and clog in a kitchen. A few things separate a system that lasts from one you'll be repairing inside two summers.
- Mount it off the line — units sited directly over grills and fryers drag grease-laden air across the coil and foul fast, so cooling is usually delivered to the prep and plating areas and the wider room while the canopy handles the heat at source.
- Grease-tolerant, easy-clean units — ceiling cassettes with washable filters and accessible coils are the usual choice because they can actually be maintained in a food setting.
- Temper the make-up air — on larger kitchens the biggest single win is conditioning the replacement air brought in to balance the extract, rather than clawing the temperature back with ever more comfort units.
- VRF for bigger or multi-area sites — a multi-split suits a single kitchen, while a VRF system runs the kitchen, servery and back office off one circuit with independent control, and heat-recovery variants can move warmth to where it's wanted.
Like other air-to-air systems, kitchen comfort units heat as well as cool (SCOP typically 3.5–4+), which is useful for a servery or staff area in winter — though, being air-to-air, they sit outside the Boiler Upgrade Scheme, which supports air-to-water heat pumps only.
Legal duties: F-Gas, worker heat and inspections
Two sets of rules bear on every kitchen job. First, only F-Gas certified engineers may legally install or work on refrigerant systems, and refrigerant must never be vented to the atmosphere — a leak has to be traced and repaired before any re-gas. Every engineer we match you with is F-Gas certified as standard. Second, while there is no legal maximum working temperature in the UK, the Workplace (Health, Safety and Welfare) Regulations require a "reasonable" temperature, and the HSE is clear that where the heat comes from the job itself — as it plainly does in a kitchen — the employer has to assess the risk and take all reasonable steps to bring it as close to comfortable as they can. Cooling is one of those steps, sitting alongside ventilation, rest breaks and hydration. On top of that, a kitchen's combined rated cooling output can tip past 12 kW once comfort cooling is added to any system already serving the servery or restaurant, and above that threshold a TM44 inspection by an accredited assessor is required at least every five years, with the report lodged on the national register. New systems run almost entirely on R32 refrigerant (GWP around 675, roughly a third of the older R410A), and as the UK's retained F-Gas quota tightens, re-gassing legacy R410A plant only gets dearer.
Grease, servicing, running costs and tax
Maintenance is where kitchen cooling really parts company with an office. Airborne grease coats filters and coils far quicker in a kitchen, so units need cleaning more often to hold efficiency and protect hygiene — most operators run a planned-maintenance contract of two or more visits a year that also covers the mandatory F-Gas leak checks and compliance records, quoted per site; our maintenance contracts guide sets out what's included. Skip it and a greased-up coil pushes energy use up and lifespan down. On running costs, business electricity is bought on commercial contracts rather than the domestic price cap, but as a reference point unit rates have sat around 25–30p/kWh through 2026 (Ofgem's cap for October–December 2026 puts domestic electricity at 26.32p/kWh). A modern system delivers roughly 4–5 kW of cooling for each kW of electricity, so a 20 kW kitchen load might draw only 4–5 kW at full tilt — very roughly a pound or so an hour at those rates, and less once the room settles; the running costs guide walks through the per-hour maths. The kit generally qualifies as plant and machinery for capital allowances, and the Annual Investment Allowance often lets the full cost be set against taxable profits in the year of purchase — worth a conversation with your accountant, because it changes the net figure materially. If you run rooms or function space above the kitchen, our hotel air conditioning guide sizes those spaces.

Sources & methodology
- Per-kW rates and kitchen price bands from UK commercial installer quote data, 2026 (supplied and installed, excluding VAT).
- Cooling-load figures (~100 W/m² dining, three-to-five times higher for kitchens) from standard commercial heat-load guidance; actual capacity requires a survey that accounts for appliances and make-up air.
- Workplace temperature duties per the Workplace (Health, Safety and Welfare) Regulations 1992 and HSE guidance (no legal maximum; "reasonable" temperature; heat controlled as a hazard).
- TM44 12 kW threshold and five-year inspection cycle per UK air conditioning inspection regulations; F-Gas certification and refrigerant handling per UK F-Gas rules.
- Electricity context from the Ofgem price cap for October–December 2026 (domestic electricity 26.32p/kWh); commercial rates differ. Worked figures are arithmetic from the stated frameworks, not quotations; capital-allowance notes are general information, not tax advice.
