Is my tenancy an assured shorthold tenancy?

An assured shorthold tenancy is the normal tenancy for renting from a private landlord. The key features of an AST are:

• It began on or after 15 January 1989
• The annual rent does not exceed £100,000
• The house or flat is let as separate accommodation
• It is the tenant’s main home

This is defined by the Housing Act 1988 (as amended).
