Any EASA Instructor can do the required one hour training for revalidation, but only UK appointed Examiners (And also now, some UK Instructors) can perform the 'administrative action'(sign the Licence, and complete the paperwork) required to Revalidate an SEP Class Rating on a UK issued EASA Licence.
Foreign Examiners can, in theory, apply to the UK CAA for authorisation to do this, but I don't know of any who have.
