At the point of Category I ME licence renewal, you are required to show proof that your CaseTrust accreditation is valid and is able to cover the period of renewed licence.
However, if the remaining accreditation period covers only part of the period of renewed licence, you must show proof (at the point of renewal) that you have taken steps to apply for renewal for CaseTrust accreditation and to submit the renewed accreditation certificate to PLRD covering the remaining period of licence once obtained.
