What Is Patio Gas

Patio gas is a specific type of liquefied petroleum gas, more commonly known as LPG, that is used to fuel outdoor appliances such as gas barbecues, patio heaters and some portable flame-effect features. It is a highly efficient and convenient fuel source, typically stored in refillable green cylinders, and is widely used across the UK during warmer months for garden cooking and heating. While the term patio gas may sound like a marketing label, it refers to a standard form of propane gas that has been packaged and regulated for safe outdoor use.

How Patio Gas Differs from Other LPG Products

LPG as a fuel comes in two main forms in the UK: propane and butane. Both are stored as liquids under pressure and revert to gas when released through a regulator. Patio gas is simply propane that has been branded for outdoor use, most notably by suppliers who offer it in specific cylinders that are compatible with clip-on regulators. The distinguishing feature of patio gas cylinders is often the green colour and the red or orange plastic cap, which helps users quickly identify the correct bottle for barbecues and heaters.

Propane, which is used in patio gas cylinders, has a much lower boiling point than butane, meaning it continues to vaporise and perform well even in colder outdoor temperatures. This makes it ideal for year-round use, whereas butane is more commonly reserved for indoor portable heaters or warmer weather use. The cylinders are designed for ease of use and portability, with fittings that match common outdoor appliances, making setup and replacement straightforward for most users.

Where Patio Gas Is Used

Patio gas is most commonly used in domestic outdoor settings, particularly in gardens, patios and camping sites. It is the go-to fuel for many gas barbecues and freestanding patio heaters, especially those that rely on a consistent and controllable flame. It provides instant heat, requires no electrical power, and is easy to store and transport. Some catering vans and mobile cooking setups also use patio gas due to its reliability and the widespread availability of refill stations or exchange services.

Because of its clean-burning nature and high energy efficiency, patio gas is also favoured for use in outdoor events and venues where mains power is not practical. It produces very little smoke or residue, making it suitable for areas where open fires are not allowed or where air quality is a concern. In commercial or semi-commercial settings, patio gas cylinders are often used to power multiple burners or heaters simultaneously, provided they are connected using the correct regulators and fittings.

Safety and Storage Considerations

Like all forms of LPG, patio gas must be handled with care and stored correctly. Cylinders should always be kept upright in a well-ventilated outdoor space, away from sources of heat or ignition. They must never be stored indoors, in sheds with poor ventilation or in direct sunlight for prolonged periods. When connecting or disconnecting patio gas bottles, it is essential to follow the manufacturer’s instructions and ensure that the regulator is securely clipped into place. If the regulator becomes worn or damaged, it should be replaced before further use.

It is also important to regularly inspect the hose and fittings for signs of wear, cracking or leaks. A soapy water test can be used to check for gas escaping from joints. If bubbles form, the connection may be loose or faulty. In such cases, turn off the supply immediately and seek advice from a qualified LPG supplier or engineer. Never attempt to repair a gas cylinder or regulator yourself.

Compatibility and Appliance Requirements

Not all outdoor appliances are compatible with every type of LPG cylinder, which is why it is important to check the manufacturer’s guidelines before purchasing patio gas. Most UK patio gas cylinders use a 27mm clip-on regulator, which is designed to match the fittings on popular models of barbecues and heaters. Some appliances, particularly those imported from abroad, may require a screw-on regulator or a different type of hose connection. Using the wrong type of gas or regulator can result in poor performance or pose a serious safety risk.

For new appliances, the required gas type and regulator size are usually listed in the instruction manual or on a label near the gas inlet. If in doubt, most major gas suppliers offer guidance on which cylinders and accessories are compatible with your equipment. Many also provide starter kits that include everything needed to connect a patio gas bottle safely and securely.

Availability and Refilling

Patio gas is widely available from garden centres, petrol stations, hardware stores and specialist LPG suppliers. When the gas runs out, customers typically exchange the empty cylinder for a full one of the same size and fitting. This cylinder exchange system avoids the need to purchase new bottles each time and ensures that the containers are safely inspected, tested and maintained by the supplier. Some providers also offer home delivery or collection services, particularly in rural areas or for commercial use.

Refilling a patio gas bottle yourself is not recommended and is often prohibited, as it requires specialist equipment and knowledge. The gas inside is stored under pressure and must be handled according to strict safety standards. Always use a reputable supplier and ensure that the bottle you receive is sealed, certified and compatible with your equipment.

Final Thoughts

Patio gas is a form of propane LPG specifically packaged and marketed for outdoor use in barbecues, heaters and other garden appliances. It is safe, efficient and reliable when used correctly, offering a clean and convenient source of energy for a wide range of domestic and commercial applications. Whether you are enjoying summer evenings in the garden or operating a portable cooking setup, patio gas provides the flexibility and performance needed without relying on electricity or permanent installations. By following proper storage and usage guidelines, you can enjoy the benefits of patio gas with confidence and peace of mind.
