Restaurant Air Conditioning Cost UK
Cooling a restaurant typically runs from around £5,000 for a small café to £25,000 or more for a large multi-zone venue with a hot kitchen — because you're really pricing two very different spaces at once: a comfort-critical dining room and a high heat-load kitchen. Here's how restaurants are sized and priced in 2026, plus the TM44 duty many operators overlook.
How much does restaurant air conditioning cost?
As a 2026 rule of thumb, budget £350–£600 per kW of cooling capacity installed for the dining side, with the kitchen pushing capacity — and therefore cost — higher per square metre. A small café or bistro of around 40 covers lands near £5,000–£9,000; a mid-size restaurant of 50–100 covers with a separate bar and kitchen zone is roughly £8,000–£15,000; a large or multi-floor venue on a full VRF system is £15,000–£25,000+. Final pricing follows a heat-load survey — these are feasibility budgets, not quotes.

Restaurant air conditioning costs by size
Indicative supplied-and-installed prices for the air conditioning system, excluding VAT. Capacities are a starting point — glazing, covers, opening hours and kitchen heat gain all shift the real load.
| Venue | Typical system | Approx. capacity | Indicative cost |
|---|---|---|---|
| Small café / bistro (~40 covers, dining only) | Multi-split with wall or cassette units | ~8 kW | £5,000–£9,000 |
| Mid-size restaurant (50–100 covers, dining + bar) | Larger multi-split or small VRF, zoned | ~18 kW | £8,000–£15,000 |
| Large restaurant (100+ covers, multi-zone) | VRF with independent zone control | ~35 kW | £15,000–£25,000+ |
| Dedicated kitchen comfort cooling (add-on) | High-capacity unit working with extract | varies | from £3,000 |
Indicative UK 2026 installer quote data, supplied and installed, excluding VAT. Kitchen cooling is priced on top of dining because of the far higher heat load, and it complements — rather than replaces — the kitchen's extract ventilation. See the wider commercial air conditioning cost guide for offices, shops and server rooms.
Why a kitchen changes the maths
A dining room needs roughly 100 W of cooling per m² as a starting point, but a kitchen can need 50% more or higher once you add ovens, grills, fryers and dishwashers — heat sources that run hardest exactly when the room is busiest. That's why restaurants are almost always zoned: the dining room, bar and kitchen each get their own capacity and controls rather than one shared system fighting itself. The chart below shows how indicative capacity scales with venue type.
Dining, bar and kitchen: matching the system to the zone
The right set-up depends on the layout, the ceiling and how independently you need to control each area.
- Dining room — discreet ceiling cassettes or slim wall units keep the space comfortable without draughts over diners; quiet operation matters as much as capacity in a room where people talk.
- Bar and waiting areas — often busy and glazed, so they carry their own load; a zoned multi-split system lets front-of-house be cooled independently of the kitchen.
- Kitchen — needs high-capacity comfort cooling that works alongside the extract canopy, not instead of it; robust, easy-clean units suit the greasy, high-temperature environment.
- Larger or multi-floor venues — a VRF/VRV system runs many indoor units off one refrigerant circuit with per-zone control, and heat-recovery variants can move warmth from the kitchen side to cooler areas.
Air-to-air restaurant systems heat as well as cool (SCOP typically 3.5–4+), so the same units keep diners comfortable in winter — though, being air-to-air, they are not eligible for the Boiler Upgrade Scheme, which supports air-to-water heat pumps only.
TM44 and F-Gas: the legal duties for restaurants
Restaurant systems frequently exceed a combined rated cooling output of 12 kW once dining, bar and kitchen zones are added together — and above that threshold a TM44 inspection by an accredited assessor is legally required at least every five years, with the report lodged on the national register. The duty falls on whoever controls the plant (landlord or tenant), and non-compliance can bring enforcement and fines from the local authority. Separately, only F-Gas certified engineers may legally install or work on refrigerant systems, and refrigerant must never be vented to the atmosphere. If you take over an existing restaurant, ask for the current TM44 certificate alongside the EPC and any gas-safety and extract records. Every engineer we match you with is F-Gas certified as standard. New restaurant systems are now specified almost entirely on R32 refrigerant, which carries a global-warming potential of around 675 — roughly a third of the older R410A it replaces — and the UK's retained F-Gas rules keep tightening the supply of high-GWP refrigerants, so servicing or any re-gas of legacy R410A plant grows progressively dearer when you inherit an older system.
Hygiene, disruption, running costs and tax
In a food environment, maintenance is not optional: filters, coils and drains need regular cleaning to protect hygiene and keep efficiency up, so most restaurants take a planned-maintenance contract of two or more visits a year, bundling F-Gas leak checks and compliance records — quoted per site. Installers usually stage the work around service, fitting out over a closure day or working overnight so you don't lose covers. On running costs, at roughly 26.11p/kWh under the July–September 2026 price cap a zoned, modern system that only cools the areas in use is far cheaper than one oversized system running flat out. A modern system delivers around 4–5 kW of cooling for each kW of electricity, so a 35 kW dining-and-bar load might draw only 7–9 kW at full tilt — near £1.85–£2.35 an hour at the current cap, and much less once the room is at temperature; our air conditioning running costs guide shows the per-hour maths. And restaurant air conditioning generally qualifies as plant and machinery for capital allowances, with the Annual Investment Allowance often letting the full cost be set against taxable profits in the year of purchase — confirm the position with your accountant, but have the conversation, as it changes the net cost materially. For the back-of-house server or till-room, our server room cooling guide covers the always-on case, and if your site also runs an office or first-floor function room, the office air conditioning cost guide sizes those spaces.
