The financial ombudsman (FOS) proposes increasing its 2010/11 budget by almost £20m to resolve an extra 45,000 cases.
The FOS's current budget forecast for 2009/10 is £94.1m but it says it is seeking to raise £113.7m for 2010/11.
In the FSA's regulatory fees and levies proposals for the upcoming financial year, it says the increase in income would be met through fees from a higher number of cases.
It says it aims to resolve 210,000 cases in 2010/11 compared to a current forecast of 165,000 in 2009/10.
In total, it forecasts 190,000 new complaints in 2010/11, compared with its current forecast of 167,000 for the current financial period.
The increase, it says, is based on the impact current market conditions can be expected to have on complaints numbers.
It says increases are expected in all product categories, with significant increases expected in banking (especially unsecured loans and consumer credit products) and payment protection insurance (PPI).
Subject to the outcome of its own consultation, the FOS proposes that the number of free cases - currently three - and the £500 case fee set in 2009/10 should remain the same in 2010/11.
Total funds on list rise from 26 to 58
