If you have set up a temporary home delivery service for plants then unfortunately this does mean you should be issuing plant passports to the customers who receive them. You might not have done this before if you only sold plants in your shops direct to customers.
We have asked for advice from Defra which has told us it will take a pragmatic view on this. So if you are doing this and only intend to do home deliveries during the current crisis (as a temporary arrangement only) then ensure you are registered as a Professional Operator and be aware of the guidance on GOV.uk and the Plant Health Portal. You might also find our plant passport guidance explains more (but bear in mind this was written before the current crisis).
