Barclays has set aside an additional £400m to repay customers mis-sold interest rate hedging products and another £600m for payment protection insurance (PPI) redress.
The bank said the interest rate hedging funds increase followed the Financial Services Authority's (FSA's) report investigating the mis-selilng to small businesses.
Barclays has so far set aside £850m, of which £36m had been used as of 31 December 2012. It said the level of provision would be kept under review as the FSA's review progresses.
Barclays also said it would give over another £600m to PPI redress, mainly as a result of a higher than anticipated response rate to "pro-active mailings in Q4".
This bring the total amount to £2.6bn, of which £1.6bn has been used so far.
