The organisation has been hit with a bill for more than £5,000 after vacating 14 Church Street.
A solicitors' letter, visible through the window, lists a string of jobs that need to be done - including repairs and re-decorating - following a survey by Sheffield firm SMC Chartered Surveyors.
It states the cost of just the survey, letter and postage is £5,366.
A Lloyds Bank spokeswoman said: 'We have received a letter regarding the schedule of repairs and we will review this in line with our usual procedures.'
