Ending Tenancy with break clause

Hello … Has anyone ended a tenancy after 6 months. Hopefully with the tenants in agreement. What is the process for the landlord to follow. I understand I have to give 2 months notice after 4 months… What else should I be doing?

I think you’d better read the Goverment changes to notice period due to covid. S21 notice is currently 4 months and in areas where there is a court backlog, such as London, you can add a year to that if the make you go to court.
