@Mike-And-Jane0 I am business rated, I just don't understand why they're being so pedantic. They have my rates account number, they know I'm a holiday let owner, I've sent them a list of all of my bookings with details of who booked, when etc, and yet they are insisting on me giving them something I cannot give.
I spoke to Airbnb and they told me although they don't have a written agreement per se the actual booking itself is the named letting agreement, as when a guest books they are accepting the host and Airbnbs policies. Unfortunately my council fails to see this. They seem to think it's the norm for when I get a booking I have some sort of agreement in writing with the guest. They think its 1975.
