Clydesdale and Yorkshire Banks are extending a sale across their range of mortgages including their lowest-ever fixed rate.
The sale will continue until 28 February, two weeks longer than was originally planned.
Both banks have reduced prices across a range of products including both standard products and those with no arrangement or valuation fees.
Helen Page, propositions director at CYBG, said: “We're delighted to be able to extend the offer to give more people the chance to save on their mortgage.”
The sale includes the banks’ lowest ever two year fixed rate of 1.59 per cent and a five year fixed rate of 2.49 per cent with no arrangement fee.
Last month Clydesdale and Yorkshire Bank announced it would close 79 branches across England and Scotland this year as it boosted its digital and mobile communications.
The bank said the number of customers using branches for day-to-day transactions across the banking industry has fallen by a third since 2011, while there has been a sharp increase in digital and mobile engagement.
