Bank of Scotland has pledged to introduce extra mobile services before it closes branches in the north and north-east.
The company confirmed earlier this week it will shut 11 more offices in Grampian and the Highlands before the end of the year.
And MP have demanded assurances customers will be offered a “high quality” alternative once the doors are closed for the final time.
A bank spokesman said it would add mobile stops in Aberlour, Cullen, Fochabers, Locharron, Portsoy and New Pitsligo.
Bosses blame a decline in the number of customers visiting branches for the closures and has pointed out many were already operating restricted hours.
The mobile banking service already stops at dozens of locations across the north and north east – covering 80,000 miles a year nationally.
It offers “key services” such as deposits, withdrawals and paying bills, but not certain others, such as opening accounts.
But critics say they have “little faith” that it will provide an adequate replacement as some customers get only a five-minute window in which to catch the vehicle before it moves off.
Branches which will close are at John Street in Aberdeen, Cullen, Fochabers, Portsoy, Aberlour, New Pitsligo, Macduff, Drumnadrochit, Broadford, Lochcarron; and Inveraray.
Staff have been told they will be offered posts at other locations and that there will be no compulsory redundancies.
North-east MSP Liam Kerr said local customers should be consulted over the best times for the mobile service to visit.
He has written to the bank warning people must not be reliant on cash machines which charge fees for withdrawals.
He said: “I am sure that the bank will want to do all it can to remain accessible for its customers, and to provide reassurance that there is still an option there in terms of local services.”
