How long is the TDG training good for?

For transport by road, rail or ship, the TDG training certificate is valid for 3 years from the date of training. At the end of that time the employee must be re-trained and issued a new certificate.

Alternatively, the employer may issue a new certificate without re-training, IF they are satisfied that the worker is still adequately trained.

The employer must keep on file a copy of the training certificate, and, if applicable a copy of the record of training or the statement of experience and a copy of the training certificate. Any of these documents would have to be produced on demand by an inspector.
