Allen Simpson, deputy chief executive of UK Hospitality, said that, due to inflation, businesses must sell goods at 124% of the price charged in 2019 to make the same amount.
He said: “It costs more to serve a pint after 22:00 than before.
“Obviously, I can’t comment on an individual premises’ pricing but businesses have to charge an amount that means they can make a profit and survive.
“Costs are rising for bars, for example with the National Insurance contributions going up in the Budget and business rates. It’s tough out there.”
Mitchells & Butlers, the pub group that operates O’Neill’s, said the policy had been in place for two years.
A spokesperson added: “Most hospitality businesses and retailers deploy a form of dynamic pricing, but this means that prices can both rise as well as fall through tactical discounts being offered in the form of time-limited promotions and fixed-price menus.
“Dynamic pricing varies on a site-by-site basis as it reflects the local market conditions, but temporary price increases tend to reflect the need to offset additional costs, such as at times when door security is required.”
