DLUHC has today (24 March 2023) issued a revised version of the How to Rent guide.
This is important because for any post 1 October 2015 assured shorthold tenancy, or ‘renewal’ tenancy (where the guide as been updated at the time of the new tenancy), the tenant must be provided with the How to Rent Guide, and that must be the most recent version at the time of the tenancy start date/’renewal’ date (or if served later, likely a later version would do). If this is not done, the landlord cannot serve a section 21 notice. (The guide can be provided to the tenant late, just so long as it is done before the service of a section 21 notice.)
It has to be provided to the tenant in hard copy, unless the tenant has expressly agreed to a PDF version by email. Sending the tenant a link will not do.
