Thanks for your reply.
Normally, if a Lease of this type is over 3 years in length, the Tenant would be expected to refund the Landlord for the Buildings Insurance premium and also be responsible for the main structure.
As your Lease is just over 12 months in length, you should not be paying for either.
As it appears you are not using your own Solicitor, I think the Landlord's Solicitor may therefore just be chancing his luck and hoping that you just sign what he has sent you! (At the end of the day, us Solicitors have to try and get the best deal for our clients).
I would suggest that you ask for these 2 obligations to be removed, as this would be a reasonable and fair request.
You can always haggle if the Landlord is not prepared to give way on both issues, and if this happens, it all comes down to the bargaining power of each party.
I hope this answers your question, and if so, I would be grateful if you could leave positive feedback.
