The end of the Energy Bill Relief Scheme  (EBRS) on 1 April could threaten the future of hundreds of thousands of small  firms, according to research by the Federation of Small Businesses (FSB).
The Energy Bill Discount Scheme (EBDS) offers  a far lower level of support for small businesses.
Although market prices have stabilised for  those fixing their contracts now or those who are on variable tariffs,  businesses that fixed last year will see huge increases as they are locked into  a high price before the government's relief.
A business paying £24,528 per year for energy  under the old government support scheme will now pay £82,539 under the new  scheme.
The FSB is calling for small firms to be  allowed to renegotiate their energy contracts that were fixed last year. It is  also calling for additional support for businesses to become more energy  efficient.
Tina McKenzie, Policy Chair at the FSB, said:
'The  jump in energy bills on April Fool's Day won't be a laughing matter but will be  a shock to hundreds of thousands of small businesses, who signed up to fixed  contracts when the government discount was guaranteed under EBRS.
'There's  much that could and should be done rather than leaving small firms high and  dry. Allowing the most vulnerable small businesses to renegotiate or 'blend and  extend' their energy contracts to better reflect lower wholesale energy prices  is the least the government and energy suppliers could do.'
