Under the Landlord and Tenant Act 1954 commercial/business tenants have the right to renew their lease, unless they have given up this right by virtue of contract.
At the end of a tenancy the Landlord should serve a notice on the tenant terminating the lease. This notice will state whether or not the landlord will oppose a new lease.
At this point, surveyors are appointed by both parties to negotiate and agree on the terms of the new lease, this will include items such as; rent payable, repair obligations etc.
Failure to agree on the terms will result in applying to the court for a new lease.
Throughout this process there are notices which are highly time sensitive and must be served by the solicitors within the strict time scales.
