Thanks for your question.
If you wisht o import fresh fruit and vegatables in to the UK, or in to the European Economic Area then you they would have to meet the standards set across the EEA . If you wish to import in to the UK then you would have to obtain a Certificate of Conformity from Department for Environment, Food and Rural Affairs (DEFRA).
I think the department that deals with this is the Horticultural Marketing department I would suggest that the best way forward would be to give them a telephone call and ask to be reffered to the relevant forms and literature for your purposes
It would also be sensible for you to familiarise yourself with HMRC’s starting guidance for people considering importing:-
