C1+E is the entitlement that lets a 7.5 tonne vehicle tow something substantial. It appears on a lot of older licences without the holder ever noticing, and it is the licence horsebox owners, event crews and utilities contractors keep discovering they need the hard way.
C1 is a vehicle between 3,500kg and 7,500kg. The +E is trailer entitlement: it lets you tow a trailer over 750kg behind that vehicle, with the vehicle and trailer together weighing no more than 12,000kg.
Without the E, your trailer is capped at 750kg — which is a small box trailer, not a horse trailer, not a plant trailer, not a generator.
Licences issued before 1 January 1997 typically carry C1+E as well as C1, which means a large number of people towing horse trailers are legal and have no idea, and an equally large number assume they are covered when their licence was issued after 1997 and they are not.
The categories are printed on the reverse of the photocard with valid-from and valid-to dates. Two minutes with your licence now is cheaper than a roadside conversation later.
The difference is the size of what you are towing with. C1+E tops out at 12,000kg for the whole combination. C+E — Class 1 — has no such ceiling and covers a 44-tonne articulated lorry.
If your towing is genuinely within 12 tonnes, C1+E is quicker and cheaper. If you are looking at commercial haulage, skip it and go for C+E; the earnings difference is substantial and C+E covers everything C1+E does.
The shape is familiar: D4 medical, D2 provisional application, theory if you do not already hold a valid pass, then training and the practical test.
The practical adds an uncoupling and recoupling exercise — detaching the trailer, securing it, then reconnecting it correctly — alongside the reversing manoeuvre and the on-road drive. It is a procedure to learn rather than a skill to acquire, and it is checked carefully because getting it wrong on the road is dangerous.
For non-commercial use, such as your own horsebox, no Driver CPC is needed. For paid work it is.
It lets you drive a vehicle between 3,500kg and 7,500kg while towing a trailer over 750kg, up to a combined maximum of 12,000kg.
C1 is the 7.5 tonne vehicle entitlement; E is the entitlement to tow a trailer heavier than 750kg behind it. Together they permit a combination up to 12,000kg.
If your car test was passed before 1 January 1997, usually yes. Check the category list on the back of your photocard. Licences issued after that date do not include it.
C1+E is capped at 12,000kg for vehicle and trailer combined. C+E — Class 1 — covers full articulated lorries up to 44 tonnes with no equivalent ceiling.
If the trailer is over 750kg and you are towing it with a vehicle over 3,500kg, yes. Loaded horse trailers are comfortably over 750kg, so this catches most equestrian setups.
