If you do not renew within your grace period, you will fully lapse from LTA Coach Accreditation and you will be considered a non-Accredited coach.
If you wish to re-join Coach Accreditation, you will need to apply as if you are a new coach who has never been Accredited. You will therefore need to ensure you have met all the requirements as a new member. This will include a DBS issued less than one year ago.
