The Financial Ombudsman Service (FOS) plans to increase the levy on financial firms by an additional £16 million.
The Ombudsman has today launched a consultation, which includes proposals to increase the current £70 million levy to £86 million by 2026/2027.
The FOS is also advising on increasing the fee from £650 to £680, in line with inflation.
The ombudsman also expects to handle more complaints about bank and consumer loans – the category that includes mortgage complaints – in 2026/2027.
The FOS said today that it expects 79,900 complaints in the ‘other bank and consumer credit’ group in 2026/2027, an increase of 1.8% on the 78,500 it is currently handling for 2025/2026.
The FOS has not specified how many specific mortgage complaints it expects to see, or how many relate to brokers or lenders.
Last month, the FOS reported that homes will be charged mortgages and buy-to-let (BTL) first Mortgage complaints both increased by 27% between July and September this year.
