Simon Michaels, chief executive of business solutions at HW Fisher, said: "Many businesses who needed a smaller loan or indeed any size loan opted for CBILS because it was the only option at the time.
"Now that the bounce back loan has been introduced (£50,000 or less) those that had a loan of £50,000 or less through CBILS would be better of switching it to a BBL.
"The interest rate differential means a potential 50 per cent to 60 per cent variation in repayments between CBILS and BBL – a little known fact which banks do not seem eager to talk about.
"A cynical view would be that there is no incentive for banks to encourage a switch to Bounce Back Loans during the first 12 months – the interest will be paid at a higher rate by the government."
A spokesperson for banking trade body UK Finance said: "Any customer with a business interruption scheme loan or overdraft of £50,000 or less will be able to switch that facility to a bounce back scheme loan should they wish to do so over the next few months by arrangement with lenders.
"Pricing is only one aspect of the product and customers would need to consider other differences with their existing facilities."
While a Treasury spokesperson told The Sun: "Our various loan schemes, which have been introduced at speed and are available to businesses of all sizes, are helping hundreds of thousands of firms get through the crisis.
"All accredited lenders will allow customers who have been approved for Coronavirus Business Interruption Loan Scheme to transfer their loans into the Bounce Back Loan Scheme."
In April, banks were warned it's their turn to repay the favour and bail out small businesses - more than a decade after they were saved during the financial crisis.
Yet a couple of weeks later, only 2 per cent of small businesses had received coronavirus loans.
