A new 'How to Rent Guide' has been published on 10 December 2020, which can be found here https://www.gov.uk/government/publications/how-to-rent .

As a reminder, for any post-1 October 2015 assured shorthold tenancy, or 'renewal' tenancy where the guide has been updated, the landlord must provide the tenant with the How to Rent Guide, and that must be the most recent version at the time of the tenancy start. Otherwise the landlord will not be able to avail themselves of a section 21 notice procedure to recover possession of the property. The How to Rent Guide must 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.

Intriguingly, as well as including the new electrical safety regulations, the updated version of the How to Rent Guide notes the forthcoming ending of section 21 while explaining that section 21 is still valid in the meantime.
