Firms said cancellations have come ‘thick and fast’ since the Prime Minister announced new restrictions.
These measures will include an extension of mask-wearing from Friday, a return to working from home on Monday, and mandatory Covid passports for large venues from Wednesday.
Bosses have highlighted that work-from-home guidance and vaccine passports will have a particular impact during the key Christmas period on retail, hospitality and leisure firms which have been battered by the pandemic for the past two years.
Kate Nicholls, chief executive of the UKHospitality trade group, said the measures “risk devastating the hospitality sector amid its most important time of the year”.
Sy het bygevoeg: “We therefore desperately need support if we are to survive this latest set of restrictions and urge the Government to stand behind our industry.
“That means full business rates relief, grants, rent protection and extended VAT reductions. Anything less would prove catastrophic.”
Firms have seen business rates support heavily reduced in recent months, while VAT across a raft of hospitality products increased from 5% aan 12.5% at the start of October and is set to return to 20% in April.
Chris Soley, chief executive of North East-based brewer and pub group Camerons Brewery, said on social media that he has seen cancellations come “thick and fast” since the new restrictions were announced, and joined the call for support.
He tweeted: “Cancellations coming in thick and fast. This is like early March 2020 when people were told not to got to the pub but we had no support.
“Urgent government grants, rates, furlough, extended VAT and rates support needed.
“Our sector needed Christmas to try and recover.”
Elders, Jeremy Joseph, owner of the G-A-Y nightclub, said there has been more “nervousness” about going out in the last couple of weeks since concerns about the Omicron variant emerged.
He told BBC Radio 4’s Today programme: “I feel like I’m constantly walking on eggshells and in survival mode.”
Mr Joseph said the new restrictions “don’t make any sense”, pointing out that he has three venues and each venue will have different rules.
“It makes no sense. It’s as if this Government thinks that Covid will go ‘That venue has a capacity of under 500 so I won’t go in there’," hy het gesê.
Intussen, the Night Time Industries Association (NTIA) also warned that leisure firms should ”not be thrown under the bus” with restrictions which will hit the recovering sector.
The trade body’s chief executive, Michael Dood, gesê: “The pre-Christmas period is absolutely crucial for our sector and reports today that Plan B, including vaccine passports, will have a devastating impact on a sector already so bruised by the pandemic.
“The Government’s own report on the subject concluded that vaccine passports wouldn’t even have a significant impact on virus transmission.
“You do, daarom, have to question the timing and rationale for this announcement.
“Is this sound, evidence-based public policy-making, or is this an attempt to move the news agenda on from a damaging story about the Downing Street Christmas party?
“Nightclubs and bars must not be thrown under the bus for the Prime Minister to save his own skin.”
