It is critical that Landlords, or their agents, serve the most up-to-date version to their tenants. In view of how important this is, the Guild of Letting and Management is advising landlords not to save the document as a PDF. They recommend instead to save the website address so there will be access to the latest version.
In the event of further action, proof that the document has been served to the tenant is imperative. The guide can be sent as a hard copy format or, with the tenant's consent, via email in PDF form.
Failure to serve the document correctly will invalidate any Section 21 (form 6a) served.
