Motorhome on Eurotunnel & Channel ferries: height & gas (2026)
Two things decide a motorhome's Channel crossing: your rig's true travelling height (which sets the carriage and the price band) and your gas (declare it, switch it off). LeShuttle (Eurotunnel) carries vehicles up to 4.2 m high and 18 m long — anything over 1.85 m simply rides the single-deck carriages — but it refuses vehicles propelled by LPG (liquefied petroleum gas), while allowing the cooking/heating cylinders most motorhomes carry (47 kg per cylinder, 50 kg total, switched off). Ferries (DFDS, P&O, Irish Ferries) band by height and length — some from as low as 2.25 m — and allow up to three gas cylinders (47 kg total), turned off and declared. Measure to include roof boxes, domes, and rear bikes, and book the band that matches.
Getting a motorhome across the Channel is simple once two numbers are right: how tall you really are, and what the operator wants you to do with your gas. This page sets out how LeShuttle and the three main ferry lines classify a motorhome by size, what each costs you above a height threshold, and the gas-cylinder rules — including the one that catches people out, LeShuttle's ban on LPG-propelled vehicles (as opposed to the ordinary gas locker, which is fine). The figures are dated and sourced from the operators; fares and bands change, so confirm on the operator's booking tool before you pay.
- Measure your true height
- Measure on flat ground, including roof box, satellite dome, air-con pod, and aerial; count rear bikes toward length. Book the band that matches — under-declaring risks a later sailing or a top-up charge at the port.
- LeShuttle — generous on size, strict on LPG fuel
- Carries up to 4.2 m high / 18 m long (over 1.85 m = single-deck). Refuses vehicles *propelled* by LPG. Domestic cooking/heating gas is fine: 47 kg per cylinder, 50 kg total, fixed tanks under 80%, switched off and declared.
- Ferries band by height & length
- DFDS up to 4 m (length bands ~7 / 10 / 12 m); Irish Ferries splits at 2.25 m; P&O around 2.3 m / 6 m before you contact the freight team. A tall rig can pay more by sea than through the tunnel.
- Gas: declare it, turn it off
- Every operator: up to 3 cylinders / 47 kg total, shut off at the valve and secured for the crossing, declared at check-in. Passengers can't stay on the vehicle deck under way anyway. Standard maritime safety.
Measure your true height first
Every operator classes a motorhome by size band, so the crossing starts with an honest tape measure. The figure that matters is your real travelling height and length — not the brochure number.
- Height: measure on flat, level ground to the highest fixed point — and add anything mounted up top: a roof box, satellite dome, air-conditioning pod, or aerial.
- Length: include a rear bike rack and the bikes on it, plus a tow-bar or A-frame. Several operators price by length as well as height.
- Book by the real number: declaring a band too small risks being moved to a later departure or charged the difference at check-in. It isn't a fine — it's a space-and-safety allocation, so the manifest has to match the vehicle.
Knowing your rig's exact profile is the same habit that keeps you off low bridges and out of tight lanes — see motorhome dimensions for navigation for how to record height, length, width, and weight once and use them everywhere.
LeShuttle (Eurotunnel): size & the LPG rule
The tunnel is the most generous on height of the Channel options, and the fastest (about 35 minutes). Vehicles over 1.85 m ride in the taller single-deck carriages, so a tall motorhome is routine.
- Maximum size: up to 4.2 m high, 18 m long (vehicle plus caravan or trailer combined), and 2.55 m wide (excluding mirrors).
- The LPG distinction — the one to get right: LeShuttle refuses any vehicle propelled by LPG or another flammable gas, even as a secondary fuel. That's about the engine. The gas you cook and heat with is allowed: domestic cylinders and fixed habitation tanks travel, within limits.
- The cooking/heating gas limits: up to 47 kg per cylinder, 50 kg total per vehicle, fixed tanks under 80% full, all switched off and declared at check-in, where staff inspect them. LNG, CNG (liquefied and compressed natural gas) and hydrogen are refused.
So the practical read: a normal coach-built motorhome with a gas locker crosses without fuss; only a van whose engine runs on LPG is turned away. If that's you, a ferry is the alternative.
The ferries: height & length bands
The three lines a motorhome is most likely to book price by height and length band. A tall rig that sails freely through the tunnel can sit in a higher-priced band at sea, so it's worth comparing.
| Operator | Height | Length bands | Above the band |
|---|---|---|---|
| LeShuttle (tunnel) | Up to 4.2 m (over 1.85 m = single-deck) | Up to 18 m combined | — |
| DFDS | Up to 4 m | ≈ 7 m / 10 m / 12 m | Freight for longer |
| Irish Ferries | ≤ 2.25 m, then a higher band | < 8 m / 8–12 m | Freight over 12 m |
| P&O Ferries | ≈ up to 2.3 m standard | Up to ≈ 6 m | Contact the freight team |
Bands and fares move with the season and the route, and the P&O figures above were the hardest to confirm from the operator directly — always check the exact band on the operator's own booking tool before you pay. All of them count roof items in the height and rear racks in the length.
Gas on board: the rule that travels
Across every operator, the gas rule is essentially the same, and it's a maritime safety rule rather than an operator quirk: declare your cylinders, shut the gas off at the valve, and secure the bottles for the crossing. Passengers can't remain on the vehicle deck while the ship is under way, so nothing needs to be running.
| Operator | Cylinders / weight | Key rule |
|---|---|---|
| LeShuttle | 47 kg per cylinder · 50 kg total (tanks < 80%) | Off, declared, inspected; LPG-propelled vehicles refused |
| DFDS | Up to 3 · 47 kg combined | One may stay connected (e.g. fridge); rest off; declared |
| Irish Ferries | Up to 3 · 47 kg combined | Closed & secured away from heat; declared; no spare fuel cans |
| P&O Ferries | ≈ 3 · 47 kg combined | Off, secured, and declared (confirm current terms with P&O) |
The gas you refill on the far side is a separate question with its own country quirks — see motorhome LPG in Europe for the four fill adapters and which one each country uses.

FAQ
Can I take an LPG motorhome through the Eurotunnel?
Draw the distinction carefully. LeShuttle refuses vehicles that are *propelled* by LPG (liquefied petroleum gas) or another flammable gas, even as a secondary fuel — an LPG-conversion engine won't be carried. But the LPG most motorhomes use for cooking and heating is fine: domestic gas cylinders and fixed habitation tanks are allowed within limits — up to 47 kg per cylinder, 50 kg total per vehicle, fixed tanks under 80% full, all switched off and declared at check-in, where they're inspected. So a normal coach-built motorhome with a gas locker travels without a problem; a van running its engine on LPG does not.
How do I measure my motorhome for a ferry or the tunnel?
Measure the real travelling height and length, on flat ground, including everything that sticks out: a roof box, satellite dome, air-conditioning pod, aerial, and any bikes on a rear rack (which add to length). Operators class you by band — LeShuttle carries up to 4.2 m high and 18 m long (combined with a trailer); the ferries band by height and length, some as low as 2.25 m before a higher price. Book the band that matches your true measurement. It isn't about a fine — it's about not being sent to a later sailing or charged the difference at the port.
Do I have to turn the gas off on the crossing?
Yes, on every operator. The common rule is to declare your gas at check-in and have the supply shut off at the cylinder valve for the whole crossing, with the bottles secured against the ship's movement. DFDS lets one cylinder stay connected to a running appliance such as the fridge; the rest are off. Passengers can't stay on the vehicle deck while the ship is under way in any case, so there's nothing to run gas for. It's standard maritime safety, not an operator quirk.
Which is better for a tall motorhome — the tunnel or a ferry?
For height, LeShuttle is the most generous: it takes vehicles up to 4.2 m, so a tall A-class or a rig with a roof box rarely troubles it (over 1.85 m simply rides in the single-deck carriages). The ferries carry tall motorhomes too — DFDS up to 4 m — but several price by height above about 2.25–2.3 m, so a tall rig can cost more by sea. The trade-off is time and preference: the tunnel is ~35 minutes and you stay near your vehicle deck; a ferry is a longer crossing with decks and food. Both work — book by your real dimensions either way.
