Aashna Shroff, personal finance expert at money.co.uk, comments:

"Barclays signed up to the SME banking undertakings on bundling - the practice of forcing a small business to open a current account when taking out a loan - back in 2002, so the fact that the breaches occurred as far back as 2010, but were not uncovered and reported until last year, is worrying. While we are pleased that the customers affected will be compensated, this should never have happened in the first place.

"All customers, including small business customers, need to be vigilant about their rights. Small businesses need to know that qualifying for a loan must never be contingent on taking out any other products with the bank granting the loan.

"If you are one of the small businesses affected by this latest issue, Barclays should put it right. But, if you're not satisfied, it's worth making sure you are getting a good deal. You can always shop around and, if necessary, switch your bank account."
