How often do I have to renew the A2 CofC

Your A2 Certificate of Competency is valid for 5 years

Your A2 CofC is valid for 5 years and you will have to renew your A2 CofC by taking the examination again every 5 years. This is to ensure that you are familiar with any regulation changes that may have happened between your first examination and 5 years later.
