You should give 4 days’ notice before the tenancy starts.
Just use Street.co.uk to create a new tenancy as usual, set the tenancy dates, and make sure the state of the tenancy has been changed 'Upcoming' and the status of the associated property is 'Let Agreed' or 'Let'. Your move-in data will then be automatically be sent to Notify.
So, if a tenant is moving in on July 22nd, make sure to add it to your CRM by July 18th at the latest.
