Gas Supply in France: What Do I Need to Know When Travelling by Motorhome or Caravan?

France is a popular destination for motorhome and caravan enthusiasts. However, anyone who relies on gas for the fridge, cooker, or heater should be aware of some important details. Whether it’s a gas cylinder, adapter, or refillable gas vessel – this guide explains what you need to know to ensure that your gas supply functions safely and comfortably while in France.

Be it for cooking, heating, or cooling – liquefied petroleum gas (LPG) is indispensable for many campers. But those travelling through France in a motorhome or caravan should inform themselves beforehand. Gas cylinder systems, connections, standards, and regulations can differ significantly from German standards – that’s why it’s important to be aware of the differences. To help you prepare thoroughly for your journey, this guide provides technical facts, practical tips, and advice on safety and the gas supply situation.
With this knowledge at hand, you’ll be well-prepared for your holiday in France.

Gas supply in France: Differences & similarities to Germany

Despite extensive harmonisation of technical regulations within Europe, there are still numerous national differences in gas supply for campers. France has its own regulations and particularities, which in some cases differ considerably from those of other countries – though there are also some similarities.

A central point is the prohibition of refilling loose gas cylinders at autogas (LPG) filling stations – which also applies in Germany. In both countries, refilling is only permitted with permanently installed gas tanks bearing a CE marking and an 80% fill stop. The standard German system of exchanging 5, 8, or 11 kg cylinders is not compatible in France: French providers use their own cylinder formats and a rental system. German small cylinders can neither be exchanged nor legally refilled.

There are also differences in operating pressure: France, like Germany, mandates 30 mbar as the standard – based on a shared European norm. However, in Germany, many vehicles still operate at 50 mbar. Older German vehicles with a 50 mbar system may still be used – provided they are technically sound, inspected, and properly documented. An adjustment is not mandatory as long as all components complied with the regulations at the time the vehicle was built.

A distinctive difference compared to Germany: Butane is more commonly offered in cylinders in France. This is not necessarily a disadvantage. More on this in the section: Propane or butane – which gas is the right choice in France?

What types of gas cylinders are available in France – and which fit into a motorhome?

France operates its own exchange system for gas cylinders, and the cylinders themselves differ entirely from those in Germany and other countries. While in some places it is common to buy cylinders, this is virtually unheard of in France.

The standard practice is to rent a gas vessel against a deposit and then exchange the empty one for a full cylinder from the same provider – similar to Germany. Important to know: without a return receipt, the deposit is usually not refunded – a detail especially relevant when returning the bottle before your journey home.

In France, 13 kg cylinders and smaller models ranging from 5 to 6 kg are the most commonly used. There are also 10 kg cylinders and modern composite models available. These sizes often differ in height and diameter from German cylinders, which should be considered when securing the container in the gas locker of your leisure vehicle. A quick check of your vehicle’s manual or a measurement of available storage space can help prevent unpleasant surprises.

Butane is widely used in French households; however, for practical reasons, campers generally opt for propane – especially when travelling to colder regions or during transitional seasons. The colour coding helps to differentiate: propane cylinders are usually grey-blue, whereas butane cylinders tend to be blue-metallic. The colour of conventional cylinders with screw connections often depends on the gas supplier and may also vary for gas cylinders with a clip-on connection.

Because GAZ butane cylinders are not factory-fitted with a safety valve, a gas cylinder valve must be installed upstream of the pressure regulation unit when used in vehicles. Pay attention to the activation pressure of the safety valve – 13.8 or 14 bar for butane (blue cover disc).

In any case, those needing a gas vessel in France should research in advance which providers operate in the destination area, which cylinder sizes are available, and whether the dimensions match your gas locker. If in doubt, campsites or local dealers can help with selection.

Connections and adapters: What do I need for French gas cylinders?

A frequent stumbling block when camping in France is the different types of connections. French gas cylinders – especially the widely used 13-kg models – typically have a different valve compared to German ones. While an external thread (type DIN 477, W21.8 mm x 1/14 LH) is standard in Germany, French cylinders use GAZ connections, FR Shell (also known as Shell-F), or so-called clip-on systems. The latter is most commonly seen at points of sale, as it is widely used in domestic settings, for example for barbecuing. For motorhomes and caravans, the Shell-F connector is primarily used, while the GAZ connector is common in more compact campervans.

For German campers, this means: nothing works without a suitable adapter for French valves. The European adapter set, such as the “Euro-Set D Professional” from GOK, has proven particularly useful. It includes several connectors, among them the D4 fitting relevant for France. These enable many French cylinders to be safely and securely connected to German pressure regulation units.

Important: Even if the German pressure regulator appears to screw onto the French cylinder valve and seems to fit, it will typically not be gas-tight. The German KLF fitting may resemble the French FR Shell, but it is not identical. Therefore: use the correct adapter. Either way, it is always a good idea to check each connection for leaks using leak detection spray or soapy water.

For cautious campers, it’s advisable to carry your own adapter in your travel kit – even though some campsites or dealers may have spares on hand. Additional adapters for Campingaz cylinders or specific clip-on systems may also be useful depending on your travel route.

LPG stations, refillable cylinders, and refuelling in France

For many campers, LPG refillable cylinders or permanently installed gas tanks with external filling points are a popular alternative to standard exchange bottles. In France, refuelling such systems at autogas stations is generally allowed – provided the system complies with current safety requirements. This includes, for example, an 80% fill stop and a certified withdrawal line.

France has a dense network of LPG stations (French “GPL”). Supply is particularly good along motorways and in larger cities. Important to know: France uses the so-called “Dish” connection. Anyone planning to refill a tank bottle or gas tank should therefore always carry the appropriate Dish adapter in the vehicle.

In rare cases, filling station operators may refuse refuelling – for instance, if they are unfamiliar with the system or consider it unsafe. In such cases, it may help to present the installation documentation or EU declaration of conformity. Often, simply pointing to the CE certification is enough to ease concerns.

Strictly prohibited: Refilling loose, portable gas cylinders at LPG stations is also strictly forbidden in France – even if adapters are available. The risk of overfilling or leakage is too great, and France aligns clearly with EU safety guidelines in this regard.

Propane or butane – which gas is the right choice in France?

France offers both propane and butane gas – depending on the region, supplier, and intended use. For campers, the key factor is the area of use and the expected temperatures.

Butane is widely used in France and often found in households, particularly for indoor use at temperatures above freezing. However, butane has a critical drawback: it barely vaporises at temperatures below 0 °C, which means that appliances would no longer receive gas. For use in motorhomes – particularly when travelling in spring, autumn or winter, or in mountainous regions – propane is the better choice.

Propane continues to vaporise even in sub-zero temperatures, providing a reliable energy source for heating, cooking and refrigeration. In practice, this means: when buying gas bottles, campers should specifically ask for propane. The colour coding may help – but only the label provides certainty.

Another consideration: with southern cylinder types or unknown suppliers, there may be variations in gas quality – such as residues or oily aerosols. Here, the use of a gas filter, such as the GOK Caramatic ConnectClean combined with pressure regulation systems like the Caramatic DriveOne or DriveTwo, or ProTwo and SwitchTwo, is recommended. This improves operational safety and protects connected appliances.

Gas supply on the road: exchange stations, filling stations, and availability

France offers an excellent infrastructure for supplying liquefied petroleum gas. Availability is particularly high in cities, along major transport routes, and in tourist regions. Many supermarkets (e.g. Intermarché, Carrefour, Leclerc), DIY stores, petrol stations, as well as camping and garden centres stock gas cylinders from their own brands or from well-known suppliers such as Antargaz, Butagaz, or Primagaz.

In rural areas, however, it is wise to replenish your supply in good time. In these regions, exchange stations can often be found at the local bar-tabac, in small shops, or directly on campsites. Agricultural cooperatives or regional energy dealers may also be points of contact. To be sure, ask locally or research suitable outlets via the suppliers’ websites.

If you are travelling with a rental bottle, note that exchanges are usually only possible at outlets of the same provider. Therefore, it is advisable to check the provider’s presence in your travel region when you first collect the bottle. A nationwide supplier offers more flexibility than a regional brand.

Tip: If you travel to France regularly, keep the empty bottle and the return receipt – you can reuse it on your next trip. This saves you a new deposit and ensures you have the appropriate exchange option during longer stays.

Safety and regulations when handling liquefied petroleum gas

Safety is paramount when handling LPG in leisure vehicles in France. The main rules are easy to follow with common sense and a bit of preparation.

Operation while driving: Anyone wishing to operate gas appliances while driving – such as the heater or fridge – must ensure the system includes a crash sensor. This has been mandatory for vehicles built since 2007 to automatically interrupt the gas flow in the event of an accident. GOK offers appropriate solutions for all needs, such as the Caramatic SafeDrive and SafeDrive PLUS, as well as the Caramatic DriveOne and DriveTwo models.

Leak checks: After each bottle change or modification, all connections should be checked for leaks using leak detection spray or soapy water. Even minor leaks can be dangerous. Hissing sounds or the smell of gas are warning signs – in such cases, stop the gas supply immediately and ventilate the vehicle.

CO and gas detectors: Carbon monoxide and gas warning devices are a valuable addition. They sound an alarm if propane, butane, or combustion by-products such as CO are detected. Small devices like these, for instance from manufacturer Thitronik, can save lives – especially at night.

No open flames: Open flames are strictly forbidden when handling gas cylinders – including during changes or inspections. Smoking nearby must also be strictly avoided.

Cylinder storage: Gas cylinders must only be transported upright and secured. This also applies to spare bottles. Tipping over or laying the bottle down can lead to dangerous situations.

Practical tips from campers for campers

Many motorhome and caravan owners share valuable experiences on gas supply in France in forums and travel reports. We’ve done some research. Here are some of the most important practical tips:

Plan gas reserves: For short trips, two full 11-kg bottles from Germany are often enough – especially in summer. If you’re staying longer or travelling in cooler seasons, plan the switch to a French bottle early.

Swap bottle at the start: A proven strategy is to rent a French bottle at the beginning of the trip and keep your German one as a reserve. That way, you use the French one first and return it empty – while the German bottle is ready for the journey home.

Don’t forget the adapter: Even if the German regulator seems to fit, it usually doesn’t seal properly. A set of adapters including the D4 for French bottles is essential.

Campsites often help: Some sites lend out adapters or help with exchanges. If you’ve forgotten your own set, you might get lucky – but don’t count on it.

Check gas quality: Campers occasionally report unusual flame colours or odours – signs of contamination. To be safe, install a gas filter and ensure flames burn blue, not orange or red.

Organise returns: You usually only get your deposit back with a return receipt – so keep it safe. Ideally, return the bottle to the same chain where you rented it. Some stores otherwise refuse or only partially refund the deposit.
