A current exemption in UK law, commonly known as “grandfather rights”, allows anyone born before 31 December 1964, to use plant protection products (PPPs ) authorised for professional use on their own or their employer’s land, without having to hold a certificate (of competence) although they should still be suitably trained and competent for their job. The Plant Protection Products (Sustainable Use) Regulations 2012 allows this exemption to continue until 26 November 2015, after which everyone who uses PPPs authorised for professional use must have a certificate. In addition, after 26 November 2015, it will be an offence for anyone to purchase PPPs authorised for professional use unless they have ensured that the intended end user has a certificate. If you don’t already have a certificate, you will need to get one by 26 November 2015 so that you can continue to use PPPs as part of your job after that date.
