When do you need a C1 licence for a motorhome? The 3.5-tonne rule explained
C1 licence and motorhomes: the 3.5-tonne rule, the pre-1997 grandfather rights on UK licences, why 95% of rentals drive on a car licence — and the payload trap.
By Clément Lacaille, editor of Van-Comparator · updated
It is the question before every first rental: “is my licence enough?”. Good news: in the vast majority of cases, yes. Here is the exact rule, and the few exceptions worth your attention.
The 3.5-tonne rule
A standard category B car licence covers any vehicle whose gross vehicle weight does not exceed 3.5 tonnes — which means virtually the whole rental market: campervans, converted vans, semi-integrateds, alcoves and most A-classes are type-approved just under that bar, precisely to stay accessible on a car licence. On Yescapa, Goboony, Roadsurfer or Indie Campers, over 95% of listings drive on the licence you already hold. The breakdown by vehicle type is in what licence for a motorhome.
When is C1 required?
The C1 licence covers vehicles from 3.5 to 7.5 tonnes: large luxury A-classes, liners, some truck conversions. Expect €1,500-2,500 of training, a medical exam and periodic renewal. In the rental world these vehicles are rare — if a listing requires C1, it says so in black and white. Special case: the big American RVs rented in the USA (Cruise America — soon compared here — or Outdoorsy) drive on a standard car licence plus an International Driving Permit — US rules are more permissive for private motorhomes.
Where the 3.5-tonne bar comes from — and the pre-1997 UK rule
The threshold is no rental-industry whim: it is set by EU Directive 2006/126/EC on driving licences — category B stops at 3,500 kg gross weight, C1 covers 3,500 to 7,500 kg, and the UK kept the same architecture after Brexit. The detail that matters most to British drivers: if you passed your car test before 1 January 1997, your licence already carries C1 as an acquired right (the “grandfather rights”), so you can drive motorhomes up to 7.5 t — check the categories on the back of your photocard. From age 70, that C1 entitlement is only renewed with a D4 medical examination; drivers who passed in 1997 or later must sit a separate C1 test to gain it. That is why heavy A-classes on British rental fleets are often listed as “pre-1997 licence or C1 required”. If you are renting in England, our motorhome and RV hire comparison for Birmingham sums up the GOV.UK categories and what to check on a listing before booking.
The real issue: payload
The trap is not the licence, it is overloading. A semi-integrated type-approved at 3,499 kg sometimes leaves only 400-500 kg of payload: four passengers, water, bikes and food, and you are close to the limit. At a roadside check the fine lands, and the insurer may come after you. Weigh your load mentally, and travel with tanks half full.
Insider tip
If you hesitate between an A-class loaded to the brim at 3.5 t and a lighter semi-integrated, take the second: same licence, better payload margin, lower consumption. Trip comfort rarely hinges on 50 extra centimetres — see which RV for which trip.
Van-Comparator’s own data
What each motorhome size costs
Reading by Clément Lacaille, the site’s editor, as of 22 Sept 2026
The licence question is about weight, and weight follows the vehicle type. Across our last four weeks of readings, the median “from” price runs from about €65 a day for a campervan to €98 for a semi-integrated RV. The heavy A-class units that can exceed 3.5 t are rare in our data (28 cities): if you hold only a car licence, the table below shows you give up little by staying with a van or semi-integrated model.
Median price by vehicle type, readings from 17 Sept 2026 to 14 Oct 2026
| Type | Destinations | Readings | Median (€/day) |
|---|---|---|---|
| Campervan | 100 | 384 | €70 |
| Converted van | 116 | 448 | €80 |
| Alcove motorhome | 93 | 325 | €89 |
| A-class motorhome | 46 | 137 | €95 |
| Semi-integrated RV | 105 | 383 | €98 |
