Restaurant and cafe air conditioning in the UK is a commercial heat and grease problem, not a living-room split. Kitchens, espresso machines, glazing and door openings drive load. 2026 illustrations for a small high-street cafe often start in the high thousands once cassettes, electrics and out-of-hours install are honest. House multi-split from-prices fail by the first lunch rush.

Why hospitality breaks domestic quotes
Cooking and beverage equipment dump heat into spaces that also need customer comfort. Grease-laden air fouls coils faster than a bedroom. Opening hours stretch into evenings when outdoor noise complaints rise. Staff zones and dining zones rarely share one happy set-point.
Formats skew to high-level walls, cassettes and ducted supplies that keep plant out of splash zones. Outdoor condensers on flat roofs or yards need grease-aware maintenance access.
- Size for peak service, not empty morning setup.
- Plan filter and coil cleaning more often than a house contract.
- Separate kitchen extract issues from comfort cooling where possible.
- Landlord and high-street discharge consents can stall outdoor siting.
2026 cost illustrations
Treat as illustrations, not a tariff. A tiny coffee counter with one indoor might still overlap a heavy domestic job in the low-to-mid thousands. A full restaurant floor with multiple indoors, condensate pumps, three-phase and weekend commissioning climbs into higher thousands or beyond. Making good after ceiling works is a real line item.
If total cooling output exceeds 12 kW, air conditioning inspection duties may apply. Budget compliance beside the install.
When not to buy a house split
Do not hang a domestic fascia over a pizza oven and hope. Do not skip grease filtration conversations. Do not site the outdoor where delivery cages block service panels.
When the building only allows a small condenser footprint, say so early. Undersized plant with a premium badge still loses on a hot Saturday.
How to brief the survey
Covers, peak covers per hour, kitchen equipment list, hours, ceiling photos, outdoor options and whether you stay open during works. Mention grease and existing extract.
Use the quote form. Hospitality-experienced F-gas firms will not price from a bedroom calculator.
Frequently asked questions
Can a cafe use the same AC as a house?
Sometimes for a tiny seating bay with low equipment heat. Most trading floors need light-commercial design and tougher maintenance.
How often should restaurant AC be cleaned?
More than annual domestic visits. Greasy sites often need indoor attention several times a year. Put it in the contract.
Does TM44 apply to restaurants?
If the air-conditioning system's effective rated cooling output is over 12 kW, inspection rules can apply. Many full-service sites clear that threshold.
