Should you shut on a quiet Monday? The break-even sum most pubs get wrong

Don't decide whether to shut on a quiet night by asking whether that night covers its share of the rent. It never will. Ask what you'd actually save by closing. On my arithmetic one bar shift from 6pm to 11pm costs about £96 in 2026 once holiday pay, employer's National Insurance and the extra energy are in. At about £2.23 of gross profit on a standard lager, that's 43 pints, roughly nine an hour. Sell more than that and opening makes you money, even if the night looks dead.

Quiet midweek nights come up in every licensee group I'm in, usually as "is it worth opening Mondays?" with forty answers and no sums. Half say close, you're burning money. The other half say never close, you'll lose your regulars. Both can be right. It depends on one number, and most people work it out wrong.

The mistake: dividing the rent by seven

The usual reasoning goes: my costs are £X a week, so each night needs to take £X divided by seven, and Monday doesn't, so Monday's losing money. That's the wrong question. Your rent, your rates, your insurance, your Sky or TNT subscription, the cellar cooler, the line cleaning and the loan all get paid whether the door's open on a Monday or not. Closing saves you none of it.

What closing saves is only what opening adds. That's the marginal cost: the staff hours you wouldn't pay and the energy you wouldn't use. Everything else is the same with the door locked. So a quiet night doesn't have to cover the rent. It only has to beat the cost of turning the lights on.

What one quiet bar shift actually costs in 2026

Cost of opening, 6pm to 11pm, one member of staff	Amount	Where it comes from
5.5 hours' pay at the National Living Wage, including half an hour to close down	£69.91	£12.71 an hour from April 2026
Holiday pay building up on those hours	£8.44	12.07% for irregular-hours staff
Employer's National Insurance	£0 to £10.49	15% on earnings over £96 a week. £0 if your Employment Allowance still has room
Extra electricity and gas for the session	£7.20	Illustrative: 30 kWh at 24p. Read your own meter
Total	£86 to £96	Author's arithmetic

A few notes on that table. The National Insurance line depends on whether this shift tips someone over the £96 a week secondary threshold, and on your Employment Allowance, which lets eligible employers knock up to £10,500 a year off their employer's National Insurance. Many small pubs use the whole allowance up before the year's out, so I've shown both ends. If the person is under 21, employer's National Insurance on their pay is 0% below £967 a week. If you've got a workplace pension on top, add that.

The energy figure is the one I'd trust least, because it's my illustration, not a published number. The cellar cooler runs whether you open or not, so it isn't in there. What opening adds is lights, heating, the glasswasher and the music. The way to get your real figure is simple: read the meter when you open and when you close on a quiet night, then do the same across the same hours on a night you're shut. I set out the unit prices pubs are paying in what electricity costs a pub per pint.

The break-even sum

An average standard lager is £4.89 on the Morning Advertiser's 2026 survey. Take VAT off and work it at a 55% wet GP and there's about £2.23 of gross profit in each one. So:

Cost of the shift	Pints to break even	Pints an hour over 5 hours	Takings inc VAT
£86 (Employment Allowance covering the NI)	39	about 8	about £191
£96 (paying the NI)	43	about 9	about £210
£96 shift, but your wet GP is 50%	47	about 9 to 10	about £230

Author's arithmetic. Gross profit per pint is selling price less VAT less cost of the beer. Your own prices and GP move every row, so redo it with your numbers.

Now look at your actual quiet night. If it's doing 25 pints across the whole session, closing saves you money. If it's doing 60, it's making you a bit, even though it looks like a ghost town and feels worse. Most people judge it by how the room feels at 8pm. Count the pints instead.

The things the sum doesn't catch

The arithmetic is the starting point, not the whole answer. These are the bits I'd weigh before shutting a night, in both directions.

Cask ale has a clock on it. Cask Marque's guidance is to empty a cask within three days of it going on sale. Shut on Monday and Tuesday and a firkin tapped on Sunday has lost two of its three days. If your second handpull is already a slow seller, closing nights can turn it from a few pints of waste into half a cask down the drain. Either tap smaller containers before closed days, take that pump off for the start of the week, or plan the cellar so nothing's mid-cask when you lock up. The cask breather guide has the yield arithmetic.

Lines still need cleaning. Closing a night doesn't change your cleaning schedule, and beer sitting in the lines for two days is the pint you throw away on Wednesday. Work out when the clean falls. Line cleaning and your stock variance covers what each clean costs you in beer.

The quiet night is often someone's whole week. The regular who comes in every Monday for two pints and the crossword isn't worth much on paper. But they're often the same person who brings six people on a Saturday, and once they find somewhere else for Mondays, you're relying on them coming back for everything else. I can't put a number on that and I won't pretend to. I'd just say you should know who drinks on your quietest night before you take it away from them.

Cutting a shift cuts someone's wages. Your quiet-night bar person may be the one who covers when everyone's off sick at Christmas. Shortening hours across the week usually keeps people better than taking whole shifts off one person.

The kitchen is a separate sum. A chef on a quiet night is a bigger cost than a bar shift, and food carries a different GP. Plenty of pubs open the bar and close the kitchen on the quietest nights. Run the same marginal cost sum for the kitchen on its own.

You're not alone, and you're not breaking your licence

In a BBPA survey reported in January 2026, 47% of pub owners said they'd cut opening hours on trading days between April and October 2025, one in seven said they were closed entirely on some days of the week, and almost two thirds said they'd cut staff hours. Closing a night isn't a sign the pub's failing. It's what half the trade is doing to get through a year of rises.

Your premises licence sets the hours during which you can carry on licensable activities, as the government's own licensing guidance puts it. It's permission, not an obligation, so shutting on a Monday doesn't breach it. Your tenancy is a different matter. If you're tied or leased, check whether your agreement has a trading or keep-open clause before you change your hours, and if it does, talk to your pubco first rather than after.

The middle options

Option	What you save	What you risk
Close the whole night	The whole marginal cost	The regulars, and cask that's mid-barrel
Open later or close earlier	The dead hours only. On most quiet nights the first and last hour do the least	Very little, if your till shows those hours are empty
Bar only, kitchen shut	The kitchen's marginal cost, usually the bigger one	Diners who only come on that night
Licensee works it alone	The wage line	Your own time, and you can't do seven nights a week for ever
Give the night a reason to exist	Nothing, you spend a bit	The cost of the prize or the act. A quiz, a darts or crib league, a games night

If you try an event, the rules on what you can and can't charge for are in pub poker, bingo, quiz and raffle rules, and the money still comes from the bar, not the entry fee. If there's music involved, check your music licence covers it.

How to get your own answer in four weeks

Pick the night you're thinking of closing. For four weeks, write down three things for it: wet takings from the till by hour, pints actually poured from your stock movement, and the meter reading at open and close. The till tells you when people come in. Stock movement tells you what really went over the bar, which matters because a quiet night is exactly when nobody's watching the comps and the half-pours. A quick count of your busiest lines at open and close does it, and the stocktake frequency guide explains why a daily spot check beats waiting for the month end.

At the end of four weeks, set the average pints against your break-even. Under it every week, cut the hours first and see what happens. Over it, keep the doors open and stop feeling bad about the empty room. It's earning.

Either way, don't stock a quiet night like a Friday. Fewer barrels on, fewer lines running, fridges filled to what that night actually sells. The par levels guide shows how to set that.

Common questions

How many pints does a quiet night need to sell to break even?

On my 2026 arithmetic, a 6pm to 11pm bar shift with one member of staff costs about £86 to £96 in wages, holiday pay, National Insurance and energy. At about £2.23 gross profit on an average £4.89 standard lager, that's 39 to 43 pints, roughly eight or nine an hour. Redo it with your own prices.

Is it cheaper for a pub to close on a Monday?

Only if Monday sells fewer pints than its marginal cost. Rent, rates, subscriptions and the cellar cooler are paid whether you open or not, so closing saves just the staff, the extra energy and any kitchen costs. Many quiet nights look dead and still beat that.

Does my premises licence say I have to open?

No. A premises licence sets the hours during which you can carry on licensable activities. It doesn't force you to trade. Check your tenancy separately, as some agreements include a trading or keep-open clause.

Can closing days cause stock losses?

Yes, mostly in cask. Cask Marque's guidance is to empty a cask within three days of it going on sale, so a closed Monday and Tuesday can take two of those days. Lines left standing between cleans can also mean beer down the drain when you reopen.
