Nightclubs and bars could sue the government to prevent a delay to Covid-19 restrictions being lifted on 21 June in England, amid mounting fears that struggling venues will go to the wall if they have to stay closed any longer. The Night Time Industries Association (NTIA) is understood to be weighing up legal action on behalf of venues such as nightclubs that have spent money to be ready to welcome guests after a year of enforced closure. According to the trade body, 54% of businesses have ordered stock, 73% have called in staff and 60% have sold tickets. Hospitality bosses said they were increasingly resigned to the prospect that rules such as social distancing and compulsory mask-wearing will not be relaxed, potentially until July. “It was almost in touching distance and now feels like it’s slipping away,” said Chris Jowsey, the head of the 1,000-strong pub chain Admiral Taverns. “We need people in the pubs to trade profitably. People might say it’s only a fortnight or four weeks, but [publicans] are hanging on by their fingertips.” Many pubs and restaurants opened when restrictions eased in April and May under the first two stages of Boris Johnson’s roadmap out of lockdown. But nightclubs and smaller venues, where social distancing is impossible, have been shut for either six months or in many cases since the onset of the pandemic. “If this gets pushed down the line, they’ve used their last cash resource to get to the point where they can open the doors,” said NTIA’s chief executive, Michael Kill. “They’ve committed money to preparing, to stocking, staff training. There’s talk about two weeks [delay], four weeks and the uncertainty is killing them.” He said the anxiety was exacerbated by a lack of any solution to a looming rent crunch. A government-imposed moratorium that prevents commercial landlords from demanding late rent payments comes to an end on 1 July. “We’ve got people who have compromised themselves financially who don’t know if they’ll get out of debt,” said Kill. “The anxiety levels associated with commercial debt, which still doesn’t have a solution with two weeks left, is exceptional.” Richard Nattriss, a nightclub owner who runs Raw in Whitby, North Yorkshire, said: “Our building is owned by a pension fund, like a lot of places, and there’s been no concession on rents. We’ve paid full rent through the entire thing and the grants haven’t covered that, so we’re desperate to open to get the cashflow.” Nattriss said he had already spent money on stocking up, amid shortage of supply of some drinks, but did not believe nightclubs would be able to open until 5 July at the earliest. “Even though they say the restrictions are lifting, we know in our heart of hearts they’re not going to do that,” he said. The government is expected to give an update on its roadmap out of coronavirus restrictions on Monday, including details on the extent to which restrictions affecting hospitality venues will be lifted on 21 June, if at all. However, one industry source said they expected the decision to be put back by a day due to the G7. The Guardian has approached the government for comment.
