The 10-year fixed rate has been cut from 4.99% to 3.89% while its 5-year fix has been cut from 3.39% to 2.99%, both at 70% loan to value.
Andy Gray, managing director of Mortgages for Barclays, said: “This is a real boost for UK homebuyers, giving them access to cheaper mortgage deals, brought about by the combination of the low base rate and the continued benefits of the Funding for Lending Scheme.
“Fixed rates are proving increasingly popular with borrowers who are looking for the certainty of securing their mortgage payments over the longer term and we have helped these customers by giving them access to some of our lowest ever fixed rates in 2013, including the 10-year fixed to be launched tomorrow.”
The products are also available to remortgage customers.
Other changes across the range include a 2-year tracker cut from base+ 1.89% to base+ 1.68% for customers with a 30%.
And the 2-year offset proposition by cutting rates 0.30% on the 2-year product and the Lifetime Offset, both at 70% LTV.
