We’d suggest that tenants who are required to give anyone access to the home they are renting, be it landlord or his contractor/s for any work that need to be done there, should also keep a contact tracing diary.
Such visits are not allowed if either the person visiting or the tenant have had covid-19 symptoms within the last 48 hours, or if anyone in the household is in isolation, or shielding following advice from a medical professional.
