If you have served a Notice and not received a Counter Notice in response by the due date, then the landlord is deemed to have admitted the premium that you proposed to pay in your Notice.

You should seek expert assistance, but can probably enforce the grant of the new lease at this level.

It may become necessary to apply to court in order to do this, and as there are certain time limits for doing so it would make sense to seek specialist help on this sooner rather than later.

You will also need to be able to demonstrate to the court that the Notice was in fact ‘served’ – i.e. proof of service will be required.
