"We believe it will open up more opportunities for advisers to have conversations with their clients about this easy and flexible way to meet their capital raising requirements."
The product is available on a maximum loan size of £100,000 and for a range of repayment periods, with options available for variable, three and five-year fixed rates.
The new 80% product carries the same adverse credit, income & property type criteria as the rest of its second charge range.
David Binney, commercial manager at Norton Home Loans, said: “A growing number of customers and brokers are realising that second charge mortgages can prove a cost-effective way of raising finance for a range of purposes, from debt consolidation to home improvements.
"However, it can often be the case that second charge mortgage customers don’t have enough available equity in their property to make use of the product, so we are really excited to be launching this 80% LTV second charge mortgage into the market.
"We believe it will open up more opportunities for advisers to have conversations with their clients about this easy and flexible way to meet their capital raising requirements.”
