Funding for free debt advisers will not be renewed.
Debt advice requests could reach 1.6 million this year.
Debtors could find it harder to get the help they need from experts as hundreds of debt advisers have stopped taking cases due to lack of funding.
Since 2005 about 500 UK debt specialists have received £25 million of funding a year to provide free advice to people struggling with debt through the Financial Inclusion Fund. However, the scheme will not be renewed by the government this year, which means many advisers will face redundancy and thousands of Britons may be unable to get hold of the help they need.
