If you mean a SEP Class Rating renewal by experience, you need to get your licence signed off by a FE on the class rating page, then complete SRG 1119 (which they need to complete a section of) and send it off to the CAA - there's no fee.
But you don't need to do it until within 3 months prior to your SEP Class Rating expiry. But ensure you do it before it expires otherwise you have to revalidate by test.
