From Wednesday 2 June, the bank, which had previously only offered five per cent deposit deals through its branch and telephone network, will open up its books to mortgage brokers.

A 3.65 per cent two-year fixed rate and a 3.89 per cent deal fixed for five years are available. Both have zero arrangement fees.

The deals are cheaper than those offered through its direct-to-consumer channel which are currently priced at 3.9 per cent and 4.04 per cent for the two and five-year fixed rates respectively, according to Moneyfacts.

Alongside the 95 per cent LTV broker launch the bank will cut rates of up to 18 basis points on purchase deals and 19 basis points on remortgage rates.
