The bank has demonstrated its commitment to further-flung customers by replacing three mobile branches which serve more than 50 local communities in Perth, Lerwick in Shetland, and Aberdeenshire.
The bank said new vans would replace the three existing vehicles that have between them driven over 200,000 miles covering villages, schools, retirement homes, community groups and worksites.
Robin Bulloch, Bank of Scotland managing director, said: "Mobile branches provide a vital lifeline to customers in some of the most remote communities in Scotland and I am delighted we are continuing to invest in this crucial service. Many people in rural areas live miles from their nearest branch and have limited access to transport. Having access to a mobile branch can make a real difference, giving people full control of their finances while ensuring financial inclusion."
The bank operates four other mobile branches, in Brodick on the isle of Arran, Oban, Portree on Skye, and Gairloch.
Mr Bulloch added: "As well as putting these new vehicles on the road and investing in branches, we are also putting a lot of effort into improving our digital capabilities, including the launch of a new mobile app for Bank of Scotland earlier this year."
The bank launched its first fleet of mobile banks in 1963. The new Perth vehicle will arrive this week, the others in early spring.
