The Financial Services Compensation Scheme has listed six firms as insolvent in July.
These include one firm that advised on mortgages, Premier Mortgage Centre in Cornwall.
Furthermore, four of the firms in default were in the financial sector, Omega Financial Solutions Limited, Luddington Broze Limited, Leech & Burgess IFA LLP and Westbury Capital Partners Limited.
FSCS says that consumers could be in line for compensation if as a result of their dealings with any of the six firms they have lost money.
The scheme adds that it has helped more than 4.5m people and paid out more than £26bn in compensation since 2001, when it was founded.
FSCS chief corporate affairs officer Alex Kuczynski says: “FSCS steps in to protect consumers around the UK when authorised financial services firms go bust.
“This vital service, which is free to consumers, protects deposits, insurance, investments, home finance and debt management.
“We want anyone who believes they may be owed money as a result of their dealings with any of these firms to get in touch as we may be able to help you.”
