Hello my name is ***** ***** I will help you with this.
Have you spoken to the Council to see if a change in planning is needed or whether they consider this a dwelling?
Ok - then I can not see how this makes it any different. Unless the terms of the mortgage prevent the staff staying over then its not a breach.It would only be a breach if there would be a change of planning needed.
They can not just define out of the blue its a place of work. They have known since 2007 and as such they cant just change their mind 9 years later.
Can I clarify anything for you about this today please?
