Pubs, bars and restaurants facing closure this winter are demanding help on top of the energy price cap to prevent an "unfolding catastrophe".
In a letter to the chancellor Kwasi Kwarteng, hospitality chief's have warned urgent clarity is needed to save businesses "on the brink of closure".
Representatives from across the sector said that while the energy price cap will provide a "critical lifeline", more support is needed so firms "not only survive but thrive again".
The groups are calling for an immediate reduction in VAT on all sales and the cancellation of business rates for the remainder of the financial year.
The trade representatives said such measures, along with an energy price cap, would help prevent "an unfolding catastrophe".
Announcing a £2,500 cap on household energy bills earlier this month, Liz Truss said there would be an "equivalent scheme" for struggling businesses.
The Prime Minister said the funds would last for six months, with "further support" provided to vulnerable sectors, including "our local pubs".
But she failed to set out when the support would commence or even how it would be delivered - leaving firms in the dark.
Business secretary Jacob Rees-Mogg will finally unveil the specific details of the package for struggling businesses on Wednesday.
The signatories of the letter to Mr Kwarteng ahead of Friday's emergency mini-Budget include UK Hospitality and the British Beer & Pub Association.
They warned the combined effect of high inflation, supply chain disruption and "skyrocketing" increases in bills has wiped out many businesses' total net income.
"Publicans are already handing back their keys and tens of thousands of businesses and associated jobs across every part of the UK are at risk".
In a joint statement, they added: "An energy price guarantee for business will provide some short-term relief for businesses on the brink of closure, but more support is needed, as well as a plan for the next six months.
"The initial announcement helped businesses breathe an initial sigh of relief, but most are still in the dark as to how the guarantee might help them".
According to a Labour analysis of ONS figures, nearly a quarter of businesses are already exposed to higher costs and are now on variable prices.
Shadow Business Secretary Jonathan Reynolds told The Mirror: "The government has failed to get a grip of the energy crisis and businesses are paying the price.
“Announcing a package doesn’t mean anything to hard working business owners. They need action.
"Dither and delay have already forced too many businesses to close in this energy crisis. Now one in every four businesses are already in jeopardy, forced to bear the full brunt of sky-rocketing bills."
