Work out your renewal date before you book anything
Your Driver Qualification Card carries an expiry date, and your 35 hours must be completed in the five years before it. You can check your recorded hours at any time through the DVSA's online service, and it is worth doing — training centres occasionally upload late, and drivers who have moved between employers sometimes find hours logged that they had forgotten about, or hours missing that they paid for.
Once you know how many hours you actually hold, plan backwards. Leaving all 35 hours to the final few months is the most common cause of drivers being off the road, because course availability tightens sharply in the run-up to the annual renewal peaks and a card cannot be extended retrospectively.
If your card has already lapsed, you are not back to square one — you simply cannot drive commercially until you have completed the full 35 hours. There is no penalty course and no test, but there is lost income for every day you are grounded, which is why we prioritise drivers in that position when we schedule dates.
