CASH-strapped firms will be waiting weeks for energy bill help amid crippling costs.
Anxious bosses have been assured by No10 they will be fully reimbursed if the support is not in place by October.
Officials are working “at pace” on a rescue plan but warn it may not be ready until November.
Households will get emergency help from next month with average bills set to be capped at £2,500 but there is no such mechanism for firms.
They said: “There is not a price cap system for businesses, we are having to build a brand new system to deliver this support.
“We will confirm details of the scheme next week.
“Support will come in parallel with households.
“The scheme will support businesses with their October energy bills, and that includes backdating if necessary.”
Emma McClarkin, chief executive of the British Beer and Pub Association, said businesses need urgent clarity or face ruin.
Aid details are set to be confirmed next week.
