This is the second rate cut to the Post Office’s three-year fixed rate mortgage in two months, and the third since its launch in November 2007, when it offered a rate of 6.09 per cent.

The mortgage continues to carry its low fixed arrangement fee of just GBP399 and can be taken out on up to 95% of a home’s value. Post Office has also slashed the rates of its three year fixed buy-to-let and self-certification mortgages to 5.99%.

Gary Fitton, Post Office’s director of lending, said: These new rate cuts put our mortgage range at the top of the comparison tables, further proving our commitment to offering customers transparent and excellent value for money products.
