The two most significant issues after the commencement of a tenancy will generally be the periodic rent reviews and the tenant's entitlement to renew his tenancy once the initial term has ended.

For leases of more than five years, the lease is likely to allow the landlord to vary the rent at fixed intervals during the term to keep it to the current commercial rate. Generally, leases only provide for upward rises; however, review clauses occasionally allow both upward and downward reviews.

As a tenant you may have rights, whether in the lease itself or as a result of statutory renewal rights, to renew the lease when the initial term ends. It is helpful to be aware of these rights and the procedure and grounds upon which they can be exercised.
