The products will be available through the Post Office’s financial services partner, Bank of Ireland UK.

The Post Office has not confirmed a launch timeline or unveiled information about rates.

As well as joining the Help to Buy Scheme, the Post Office will also increase its number of branch mortgage specialists to 100.

John Willcock, head of mortgages at Post Office said: “Joining the Help to Buy scheme is the latest in a series of steps to affirm Post Office as the go-to mortgage provider for those wanting to get their first foot on the property ladder. Coupled with the increased number of mortgage specialists to cope with unprecedented demand from movers, first-time buyers and those looking to re-mortgage, Post Office will provide more customers with the chance to speak to experts about the options available, consolidating its position as a leading player in the market.”

The Government’s Help to Buy initiative allows people to apply for a government backed mortgage with as little as a 5% deposit.

Since launch the controversial scheme has triggered over £1bn of new home loans, according to David Cameron.
