An operator’s licence is a snapshot of a business at the moment it was granted, and businesses do not hold still. The operator licensing guide handles that reality with a simple obligation: licence holders must advise the traffic commissioner of relevant changes affecting the licence within 28 days. It is one of the most commonly breached duties in licensing, usually through ignorance rather than intent, and it is entirely avoidable.
The list in the guide is wider than most operators assume:
Two features of that list deserve attention. First, the conviction duty reaches beyond the licence holder to managers, officers, employees and agents, which means you need a way of knowing: a contractual or policy requirement that staff report relevant convictions to you promptly, because you cannot notify what you do not know. Second, the list is not closed. Conditions attached at grant can add bespoke notification duties, and breaching a condition is as serious as breaching the general rule.
Changes are notified through the Vehicle Operator Licensing self service account or in writing to the Office of the Traffic Commissioner. Some changes are chargeable variations and carry a fee; simple notifications do not. The 28-day clock and the fee question are separate: a chargeable change still has to be made properly, and an unchargeable one still has to be made on time.
The guide’s warning on failure is short and should be taken at face value: any failure to notify a relevant change may lead to regulatory action against you and the licence. In practice, unnotified changes surface at the worst moments, during a DVSA investigation or a public inquiry, where they read as either disorganisation or concealment, and neither helps.
One change sits in a category of its own. Licences are not transferable, full stop. If the business becomes a different legal entity, a sole trader incorporating, a partnership reforming, a company changing hands in a way that changes the entity, it is against the law to operate as the new entity without telling the commissioner, and a new licence must be obtained before the new entity operates. This is the trap in every share sale and every “we just changed the company name” conversation: check whether the legal entity changed, because if it did, you need a licence, not a letter.
The operators who never breach the 28-day rule do not rely on memory; they build triggers. Anything touching the licence, a manager leaving, a director change, a conviction letter, a yard move, a finance event, lands with one named person who owns the question “does the commissioner need to know?” The self service account is checked against reality periodically, because the licence record should match the business as it is, not as it was. And the duty is written into the transport manager’s reporting rhythm, so the person closest to the operation feeds the loop.
None of this is heavy administration. It is a habit of telling the regulator the truth on time, which is also a fair summary of what the licence itself stands for.
Among the items on the list, the correspondence address earns special attention because of what travels to it. Call-up letters for public inquiries, DVSA correspondence and the commissioner’s formal notices all go to the address recorded on the licence. An operator who moves office, or lets post pile up at a registered address nobody checks, can miss a public inquiry notification with its 21 or 28 days of preparation time, and “we never saw the letter” is a self-inflicted wound the commissioner has heard many times. Keeping the correspondence address current, and genuinely monitored, is a small administrative act that protects everything else.
