Its buy-to-let offering meanwhile includes 5-year fixes of 3.75% at 60% LTV and 4.09% at 75% LTV, both with a £1,995 fee.
John Willcock, head of Post Office Mortgages, said: “In a competitive market it is important to stand out, and with our rates and service offering we are able to offer customers an alternative to traditional high-street lenders, whether they’re looking for a residential or buy-to-let mortgage.
“We’re dedicated to ensuring customers feel they are in safe hands when it comes to taking out a new mortgage and hope that with these new rates they also know they are getting the best deal.”
The Post Office also offers a 3-year fix of 2.48% up to 75% LTV with a £1,495 fee and a 2-year fix of 1.98% up to 75% LTV with a £995 fee.
Willcock added: “At Post Office, we are always looking for opportunities to review our product range so that we can offer our customers the best mortgage possible.
“We recognise what an important and occasionally daunting process finding a new mortgage can be, and so offer several means of support so that people can buy in the way that suits them best.
“We are committed to offering customers the best deals and service across our full range of financial services products, whatever their needs.
“By giving them the choice of contacting us online, over the phone or in one of our 11,500 branches we are able to cater to their needs.”
In 2014 the Post Office has already signed up to the government’s Help to Buy scheme, recruited over 100 mortgage specialists and re-entered the buy-to-let market.
