Walk past any high street in Britain right now and you’ll spot the same pattern. A new restaurant opens with a queue out the door, and eighteen months later there’s brown paper in the windows. The food was fine. The location was fine. The owner just ran out of money.
The numbers behind a UK restaurant are brutal once you sit down with them, and most of the cost is invisible to anyone eating dinner. Here’s what the spreadsheet actually looks like in 2026.
Rent and rates
A 60-cover site in a medium-sized UK town runs between £4,000 and £8,000 a month in rent. Add business rates on top, which the 2023 revaluation pushed up sharply for hospitality, and you’re often looking at another £1,500 to £3,000 monthly. Central London is its own universe. Operators in Soho or Shoreditch routinely pay £15,000 a month before they’ve poured a single drink.
Staff
This is where most owners get a nasty shock. The April 2025 minimum wage rise to £12.21 an hour for over-21s, plus the National Insurance threshold drop, added roughly £2,500 a year per full-time employee for the average independent restaurant. UKHospitality estimated the combined hit across the sector at £3.4 billion. For a 12-person team, that’s an extra £30,000 a year landing on the wage bill before you’ve changed anything else.
Food cost
Decent kitchens target a food cost of 28 to 32 percent of menu price. Wholesale beef is up roughly 18 percent year on year. Dairy and cooking oil have been volatile since 2022 and never really came back down. The chef who quotes a dish at £14 in January is often watching the gross margin shrink to nothing by August.
Energy
Commercial gas and electricity contracts have settled higher than pre-2022 levels and stayed there. A mid-sized restaurant burns through £1,800 to £3,500 a month on energy alone. Walk-in fridges, freezers, and prep refrigeration run 24 hours a day and never switch off, which is why refrigeration is usually the single biggest line on the electricity bill.
Equipment failure
This is the cost nobody plans for. A walk-in fridge that fails on a Friday night during service can wipe out £2,000 to £6,000 of stock in one go. Insurance often won’t cover stock loss unless the unit is on a maintenance contract. The repair itself is the smaller half of the bill. The lost stock and the lost service are what hurt.
This is why operators with any experience keep a number for emergency commercial fridge repair saved before they need it. Specialists like Be Cool Refrigeration cover most of London and the South East with same-day callouts, and the cost of having someone on the books is a fraction of what one bad Friday looks like without a contact.
Insurance, licences, compliance
Public liability, employers’ liability, buildings, contents, and stock cover together typically run £2,500 to £6,000 a year for a small restaurant. Premises licence, music licence, food hygiene registration, waste contracts, hood cleaning, gas safety certs, PAT testing. None of it is huge on its own. All of it together is usually £400 to £700 a month.
What’s actually left
A reasonable independent restaurant turning over £600,000 a year often nets between 4 and 8 percent. That’s £24,000 to £48,000 of profit for a year of 14-hour days, holiday cover, and personal guarantees on the lease. The good operators clear more, sometimes much more, but they’re the ones who watch the small numbers obsessively.
Where most owners actually go wrong
It’s rarely the front of house. It’s usually one of three things on the back of the spreadsheet.
They underestimate equipment maintenance and treat fridges and ovens as if they’ll run forever. They underestimate staff cost and assume the rota they wrote in October still works in February. They underestimate energy and pay the rolling variable rate instead of fixing for 12 or 24 months when the market dips.
The good news is none of those three are difficult to fix once you know they’re the problem. The owners who survive past year three are usually the ones who got bored of the kitchen for a week, sat down with the bills, and rewrote the bottom half of the P&L.
That’s the part nobody puts on Instagram.
