It took seven months from our first contact with Leasehold Services to obtain the Licence for Alterations. The advice is that you should not start works until this is issued. We started work in the fifth month when it became clear that landlord’s consent was going to be given. The advice back then was that building permission had to be obtained before you applied for landlord’s consent. The current guidance seems to be to that you need to find out if landlord’s approval is likely to be given before applying for building permission. There was no opposition to our proposals from Housing Services, it’s just a slow (and expensive) process. Building permission was obtained in three weeks. Our plans were drawn up by an architect, who made the building control application.
