The government says the scheme will cover families at risk of repossession because of additional loans secured on their home.
The Finance and Leasing Association says it sees this as a clear sign that secured lenders will be included in its plans.
The inclusion means that secured lenders may have to echo what first-charge mortgage lenders have signed up to and defer payments and repossession for up to two years.
Buy-to-let properties will not be included in the scheme and for borrowers to qualify for the two-year holiday they must seek financial advice from a party other than their lender to determine their eligibility for the scheme.
Borrowers will also need to prove their income loss will not be permanent.
Fiona Hoyle, head of consumer finance at the FLA, which represents 80% of all secured loan lenders, says: “One of the major challenges facing secured loan lenders is making sure they are involved in government initiatives such as the Homeowner Mortgage Support Scheme.”
