C1 Licence Requirements UK 2026: Everything You Need to Know
The Category C1 driving licence allows you to drive vehicles between 3,500 kg and 7,500 kg — commonly known as 7.5-tonne vehicles. This licence is essential for ambulance drivers, large van operators, horsebox drivers, and anyone working with medium goods vehicles that exceed the standard car licence limit. This guide covers every C1 licence requirement in the UK for 2026, including age limits, medical standards, test requirements, and what vehicles you can drive.
What Is a C1 Licence?
Category C1 is a sub-category of the HGV licence system, covering vehicles with a maximum authorised mass (MAM) between 3,500 kg and 7,500 kg. It is distinct from the full Category C licence (which covers vehicles over 7,500 kg). Common vehicles requiring a C1 licence include:
- Ambulances and rapid response vehicles
- Large horseboxes and livestock transporters
- 7.5-tonne box vans and curtainsiders
- Specialist vehicles such as mobile libraries and exhibition units
- Some recovery vehicles and plant transporters
C1 Licence Requirements Summary
| Requirement | Details |
|---|---|
| Minimum age | 18 years old |
| Prerequisite licence | Full Category B (car) licence |
| Medical standard | D4 Group 2 medical examination |
| Theory test | Part 1 (multiple choice + hazard perception) |
| CPC Module 2 | Required if driving commercially |
| Practical test | Part 3 DVSA driving test |
| CPC Module 4 | Required if driving commercially |
Medical Requirements for C1
The D4 medical examination for C1 is identical to the full HGV medical. It must be completed by a GP or approved medical practitioner and covers:
- Eyesight: minimum 6/12 in the better eye (with correction if needed), and 6/36 in the other
- Blood pressure: below 180/100 mmHg
- No untreated sleep apnoea
- No insulin-treated diabetes without DVLA approval
- No significant cardiovascular or neurological conditions
The medical costs £50–£100 and must be renewed every five years (or every year after age 45). The DVLA will not issue a provisional C1 entitlement without a completed D4 form.
Theory Test Requirements
The C1 theory test is the same as the full HGV theory test:
- Part 1 (Multiple Choice): 100 questions, pass mark 85/100. Covers road safety, vehicle safety, tachograph rules, and driving legislation. Fee: £26.
- Hazard Perception: Taken alongside Part 1. 19 video clips, minimum score required.
The full process — from D4 medical to licence in hand — typically takes 6–14 weeks. For a detailed stage-by-stage breakdown, see our guide on how long it takes to get an HGV licence.
Driver CPC Requirements for C1
If you are driving a C1 vehicle commercially (i.e., as part of your employment), you must also obtain the Driver CPC:
- CPC Module 2: Case study theory test (£26, taken at the same time as the Part 1 theory test)
- CPC Module 4: Practical vehicle safety demonstration (£55 weekday)
If you are driving a C1 vehicle for personal use only (e.g., a private horsebox), the CPC is not required. However, most employment roles requiring a C1 licence will require the CPC. For a full breakdown of CPC costs, see our CPC training cost guide.
Practical Training and Test
After passing the theory tests, you complete practical training with a qualified C1 instructor. The training typically takes 3–6 days and covers:
- Vehicle familiarisation and pre-drive checks
- Reversing exercises (required for the test)
- On-road driving in various conditions
- Load security and vehicle safety (for CPC Module 4)
The DVSA practical test (Part 3) costs £115 on weekdays and £141 on evenings/weekends. It includes an off-road reversing exercise and approximately 60 minutes of on-road driving. For a comparison of C1 training duration versus full Category C, see our guide on how long HGV training takes.
C1 vs. Full Category C: Key Differences
| Feature | C1 Licence | Category C (Class 2) |
|---|---|---|
| Vehicle weight | 3,500–7,500 kg MAM | Over 7,500 kg MAM |
| Typical vehicles | Ambulances, large vans, horseboxes | Rigid lorries, tipper trucks |
| Training duration | 3–6 days | 5–10 days |
| Training cost | £800–£1,500 | £1,000–£1,800 |
| Can tow trailer? | Yes, with C1+E (up to 12,000 kg combined) | Yes, with C+E (Class 1) |
| Tachograph required? | Only if over 3.5t and driving commercially | Yes, for all commercial driving |
Grandfather Rights: Do You Already Have C1?
If you passed your car driving test before 1 January 1997, you may already have Category C1 entitlement on your licence as a "grandfather right." Check the back of your photocard licence — if C1 is listed, you can drive 7.5-tonne vehicles without additional training, subject to passing a D4 medical. However, you will still need the Driver CPC if driving commercially.
Frequently Asked Questions
Do I need a C1 licence to drive a 3.5-tonne van?
No — a standard Category B car licence covers vehicles up to 3,500 kg MAM. You only need a C1 licence for vehicles between 3,500 kg and 7,500 kg. Most standard panel vans (Transit, Sprinter, Crafter) are under 3,500 kg and do not require a C1.
How much does C1 training cost?
C1 training typically costs £800–£1,500 for the training package, plus DVSA test fees of around £200. GS Driver Training offers all-inclusive C1 packages from £847 inc VAT.
Can I drive an ambulance with a C1 licence?
Yes — most ambulances fall within the C1 weight category. NHS and private ambulance services typically require a full C1 licence plus Driver CPC. Some roles also require additional training such as blue light driving (for emergency services).
Is the C1 test the same as the HGV test?
The C1 practical test follows the same format as the full HGV test — off-road reversing exercise followed by on-road driving. The main difference is the size of the vehicle. The theory test is identical to the full HGV theory test.
