To find out how many periodic training hours you have completed you will need to register your details online with the DVLA by following this link: https://www.gov.uk/check-your-driver-cpc-periodic-training-hours

After registering your details a password will be sent by post to the address on your driving licence. You will then be able to see how many hours you have completed, check what courses you have attended and check when you’ll receive your next Driver Qualification Card (Driver CPC Card).
