What Is an O Licence?
An O licence (Operator’s Licence) is a legal permit you need to operate goods vehicles over 3.5 tonnes for commercial purposes in Great Britain. It’s issued by the Traffic Commissioner and covers most business uses of heavier vans, lorries and trailers.
The 3.5-tonne threshold refers to the gross plated weight shown on the vehicle’s VIN plate, not how much you’re actually carrying. If you tow a trailer, it’s the combined weight that counts.
Operating without one when you need it is a criminal offence. You risk fines, prosecution and having your vehicles seized.
Do You Need an O Licence?
You need an O licence if you operate vehicles or vehicle-and-trailer combinations over 3.5 tonnes gross plated weight, and you’re carrying goods for hire or reward, or in connection with a trade or business.
When You Need One
- You run a courier, haulage or delivery business using large vans or lorries
- You operate a tipper truck for a construction company
- You tow a heavy trailer behind a van, pushing the combined weight over 3.5 tonnes
- You’re a tradesperson using a long-wheelbase van rated above 3.5 tonnes
- You operate multiple vehicles whose combined weight exceeds the threshold
- You move stock or materials between business premises in heavier vehicles
When You Don’t Need One
- You use a standard van under 3.5 tonnes with no heavy trailer
- You only carry your own tools and materials in a light commercial vehicle (under 3.5 tonnes)
- You operate vehicles exclusively on private land
- You use adapted vehicles for showman’s purposes (different rules apply)
Many businesses cross the threshold without realising it, especially when adding trailers or upgrading to larger vehicles. Always check the gross plated weight before operating.
Do You Need an O Licence for 1 Truck?
Yes. If that single truck is over 3.5 tonnes and used commercially, you need an O licence. The number of vehicles doesn’t matter. The weight and purpose of use are what trigger the requirement.
Types of O Licence
There are two main categories, each with different compliance requirements.
Restricted Licence
For businesses carrying their own goods only, not for hire or reward.
Examples:
- A builder transporting materials to their own sites
- A retailer moving stock between their own premises
- A manufacturer delivering products directly to customers
You don’t need a transport manager with a CPC qualification, but you must still meet financial standing and vehicle maintenance standards.
Standard National Licence
For businesses carrying goods for hire or reward within the UK. This means you’re being paid to transport someone else’s goods.
Examples:
- Couriers and haulage firms
- Third-party logistics providers
- Delivery companies
You need a nominated transport manager with a Certificate of Professional Competence (CPC in road haulage).
Standard International Licence
Required if you carry goods across international borders. It includes all Standard National requirements plus permissions for European or international operations.
How to Apply for an O Licence
You apply through the Traffic Commissioner for the area where your operating centre is based (the place where vehicles are normally kept overnight).
What You’ll Need
- Proof of financial standing: Bank letter showing available funds (£8,000 for the first vehicle, £4,450 for each additional vehicle on a Standard licence; £3,100 for the first vehicle, £1,700 for each additional on a Restricted licence)
- Evidence of good repute: No serious criminal convictions or regulatory breaches
- Transport manager details: For Standard licences, a nominated person with a CPC qualification
- Operating centre details: Address, number of vehicles and parking arrangements
- Maintenance arrangements: Contracts with a garage or documented in-house inspection system
Application Process
- Complete the application online via GOV.UK or by post
- Advertise your application in a local newspaper and at your operating centre for 21 days
- Pay the application fee and decision fee
- Wait for the Traffic Commissioner’s decision (typically 8 to 12 weeks)
Neighbours and competitors can object during the advertising period. Common objections relate to parking, noise, traffic and environmental concerns.
Fees
Fees vary by licence type and number of vehicles. Expect:
- Application fee: £257
- Decision fee: £401 to £1,992 depending on vehicle numbers
- Annual continuation fee: varies by licence type and vehicle count
Budget for these costs before applying. For more on the financial side of fleet management, see our guide on the hidden costs of running a fleet.
What Happens If You Don’t Have One
DVSA enforcement officers carry out roadside checks and investigate complaints. Operating without a valid O licence is a criminal offence.
Potential Consequences
- Prosecution and unlimited fines
- Vehicle immobilisation or seizure
- Prohibition from operating
- Directors banned from holding an O licence in future
- Insurance claims refused
If you’re involved in an accident and your insurer discovers you were operating without the required licence, they may refuse to pay out. This can leave you personally liable for damages running into hundreds of thousands of pounds.
O Licences and Fleet Insurance
Your O licence status directly affects your fleet insurance. Insurers ask whether you hold (or are required to hold) an O licence when you apply for cover.
If you need one and don’t have it, you breach your policy terms. Claims can be declined and your policy may be voided.
When setting up a fleet for your business, always confirm your licensing requirements before arranging insurance. Tell your insurer immediately if you add heavier vehicles or trailers that push you over the 3.5-tonne threshold.
Staying Compliant
Once you have an O licence, you must maintain it. This is an ongoing responsibility, not a one-off task.
Ongoing Requirements
- Keep vehicles roadworthy with a documented maintenance schedule
- Ensure drivers follow working time rules and tachograph regulations
- Keep accurate records (maintenance logs, driver hours, journey sheets)
- Notify the Traffic Commissioner of any changes within 28 days (new vehicles, operating centres, transport managers, company directors)
- Maintain financial standing throughout the licence period
- Renew your licence every five years
Failure to comply can result in your licence being curtailed (vehicle numbers reduced), suspended, or revoked. Public inquiries are held for serious breaches, and these can have lasting consequences for your business reputation.
The Traffic Commissioner can also issue fixed penalties for minor breaches and improvement notices for maintenance failures.
Getting It Right
If you’re unsure whether your business needs an O licence, check the DVSA guidance on GOV.UK or speak to a qualified transport consultant.
Don’t assume you’re exempt because you operate smaller vehicles. Adding a trailer or upgrading to a heavier van changes everything. The penalties for getting it wrong far outweigh the cost of compliance.
