The OFM is a variable rate mortgage currently offering a rate of 5.65% for loans with a facility to the value of the property of 95% or less. Borrowers can make lump sum reductions and overpayments each month without charge and can also request to underpay and take payment holidays.

Charles Haresnape, director of mortgage sales at NatWest, said: “Offset mortgages are becoming increasingly popular and I am very pleased that we can now offer Offset to our intermediary partners. We are constantly looking to improve our mortgage range for our brokers and help them provide a wider choice of products for their clients. By allowing their clients’ separate mortgage, savings and current accounts to ‘talk’ to each other, they will be able to save thousands of pounds in interest on their mortgage and potentially pay it off years earlier.”
