"We’re pleased to be introducing a further two competitive 80% mortgages to our current offering to increase product options for brokers and their clients."
A two-year fixed rate starts at 1.89% and a five-year fixed rate is available from 2.29%.
Both mortgages come with a £999 product fee and offer 10% overpayments per annum to support customers who require the flexibility to make lump sum capital payments.
