Category C1 (3.5 to 7.5 Tonne) Licence, Explained

#What Cat C1 lets you drive

A Category C1 licence permits you to drive rigid goods vehicles between 3.5 and 7.5 tonnes maximum authorised mass (MAM), plus a small trailer up to 750 kg. The 7.5 tonne limit is the upper bound, anything heavier than that needs full Cat C. Vehicles in this range include the classic 7.5 tonne curtainsider used by national distribution networks, plus most box vans, ambulances, horse boxes over 3.5 tonnes, and many specialist commercial vehicles.

The 7.5 tonne sweet spot exists because the limit predates EU harmonisation and a generation of UK commercial fleets is built around it. A 7.5 tonne lorry can do most multi-drop urban work without needing the heavier driver requirements that kick in above the limit. That is why so many courier and parcel companies still buy 7.5 tonne rigids in volume.

#The pre-1997 grandfather rule

If you passed your car (Cat B) test before 1 January 1997 in the UK, you automatically have C1 entitlement on your licence. Look at the back of your photocard in the table of vehicle categories. Anyone with C1 already has it for life unless they have surrendered it for medical reasons. This grandfathered entitlement is one of the most underused commercial driving benefits in the country, particularly for drivers in their 50s and 60s who never realised they could legally drive a 7.5 tonner.

There is one important catch. The grandfathered C1 expires on your 70th birthday and must be renewed every three years thereafter, with a D4 medical each time. Younger pre-1997 drivers do not need a medical until age 45, then every five years until 65, then more frequently.

#The post-1997 rule

If you passed your car test on or after 1 January 1997, you do not have automatic C1 entitlement. You need to apply for a provisional, pass a D4 medical, sit a theory and hazard perception test, and pass a practical test in a 7.5 tonne vehicle. This is a smaller version of the full Cat C process, with the same fee structure and a similar training time.

#Who needs a C1 licence

• Multi-drop delivery drivers in 7.5 tonne curtainsiders or box vans
• Ambulance drivers operating front-line vehicles over 3.5 tonnes
• Horse box owners with vehicles between 3.5 and 7.5 tonnes
• Refuse and recycling drivers in smaller council vehicles
• Mobile library and outreach service drivers
• Tradespeople running larger plant or tool vehicles
• Anyone working in catering, event services, or production using a 7.5 tonne mobile unit

#Age and medical

You can apply for C1 from age 18 if you hold a full Cat B licence. The D4 medical is identical to the one used for Cat C, and most GPs will charge between £60 and £150. The medical is checking the same set of conditions: eyesight, blood pressure, sleep apnoea, diabetes, neurological history. See the D4 medical guide for what specifically the doctor is examining.

#Theory and practical test

The C1 theory test is the same multiple choice and hazard perception structure as Cat C theory, with the same 85 out of 100 and 67 out of 100 pass marks. The questions are tailored to mid-weight commercial driving but cover the same regulatory ground (drivers hours, load security, vehicle dimensions). The DVSA fee is £26 for the multiple choice and £11 for the hazard perception.

The practical test is conducted in a 7.5 tonne vehicle provided by your training school. It runs for around 90 minutes total, the same structure as the full HGV practical test. The DVSA fee is £115 on a weekday. C1 pass rates run a little higher than Cat C nationally, partly because the vehicle is more forgiving and partly because candidates often have less commercial experience and learn cleaner habits during training.

#Driver CPC and C1

If you intend to drive C1 vehicles commercially (i.e. for hire and reward, not just personal use of a horse box), you need initial Driver CPC alongside your licence. That means modules 2 and 4 on top of theory and practical. There is one exception: drivers using C1 vehicles for non-commercial purposes only (private horse boxes, motorhomes, charity work) are exempt from CPC. The full breakdown of what each module covers is in Driver CPC modules explained.

#Cost and time investment

For post-1997 drivers, total cost runs £1,800 to £2,500 including medical, theory, training, and tests. Course length is typically three to five days of intensive training. Many candidates choose to do the full Cat C instead, partly because the cost differential is small (£500 to £1,000) and partly because Cat C unlocks far more job opportunities. If you only need to drive a 7.5 tonne vehicle and not heavier, C1 alone is the right choice.
