Barclays Bank is expecting complaints about loan insurance to continue rising after a 93% increase in the first half of the year.

The High Street bank said complaints about payment protection insurance (PPI) had soared after banks lost their legal challenge on PPI rules in April.

It received over 73,000 insurance complaints, mostly about PPI, up from 38,000 in the same period of 2010.

Overall, Barclays saw a 14% drop in complaints about its services.

"We expect PPI complaint volumes to be greater in the second half of 2011 as we see an increased number of complaints following the outcome of the judicial review," said Barclays.

"Barclays is working hard to clear PPI complaints as quickly as possible; prioritising customers who were held up in the judicial review and resolving all complaints in a transparent and efficient manner."

Recently, Lloyds said that insurance complaints it had received had more than doubled from 94,918 in the first six months of 2010 to 202,384 in the first half of 2011.
