What is a sublet renewal tenancy?

As from 1st May 2026 existing Assured Shorthold Tenancies will automatically become an assured periodic tenancies.  You do not need to enter into a new tenancy agreement with your existing sub-tenant, but any fixed end date in your original tenancy agreement will no longer apply, and the agreement will be deemed to be subject to the terms of the new Act. 

If required by your lease you will still need to obtain consent/and or register any subletting to new sub-tenants.
