I have to clarify that with the landlord. My understanding is that she wants to proceed.
Thanks I just spoke to the landlord and she said she was under the impression that all that changed in this new tenancy agreement is the date and the rent. She's coming round to me this evening to go through the agreement. Apparently she had a bit of an issue with the agent as to how much they were charging her for "changing the date and amount". So they are probably just justifying their pay!
