What Is Patio Gas

Patio gas is a type of liquefied petroleum gas (LPG), specifically propane, that is supplied in green cylinders for use with outdoor appliances such as gas barbecues, patio heaters, and fire pits. It is designed for safe, convenient use in domestic and commercial outdoor settings, particularly in gardens, terraces, or outdoor seating areas. Patio gas is popular across the UK for its ease of use, clean burning properties, and reliable performance even in cold weather.

Unlike some other LPG cylinders, patio gas bottles are fitted with a clip-on regulator — typically 27mm — which makes them quick and easy to connect and disconnect without the need for specialist tools. This makes them ideal for domestic users who want a simple and safe setup for summer cooking or year-round outdoor heating.

How Patio Gas Works

Patio gas works by releasing propane from a pressurised cylinder in vapour form, which is then burned to generate heat. The regulator controls the pressure to ensure a steady and safe flow of gas to the appliance. Because propane has a low boiling point, it remains effective even in colder temperatures — a key advantage for UK use, where temperatures can drop significantly, especially in the evenings or off-season.

Once connected, patio gas supplies a clean, consistent flame suitable for heating outdoor areas or cooking food without producing smoke or ash. It’s widely regarded as more convenient and environmentally friendlier than using solid fuels like charcoal or wood, especially for households wanting instant heat and minimal mess.

What’s the Difference Between Patio Gas and Other LPG?

The main difference between patio gas and other LPG types lies in the regulator connection and intended use. Patio gas is propane, just like many other LPG options, but it is specifically bottled in green cylinders with a 27mm clip-on fitting. Butane, another form of LPG, is often used indoors and in portable heaters, and typically comes in blue bottles with a screw-on regulator.

The propane used in patio gas bottles can also be found in red or orange cylinders used for camping or industrial applications. However, these cylinders usually require a different regulator type and are not interchangeable without the correct fittings. If you’re using a barbecue or patio heater designed for patio gas, using the wrong cylinder can result in leaks or poor performance. 

Choosing the Right Size and Cylinder

Patio gas is available in different cylinder sizes to suit various outdoor appliances. Smaller bottles are ideal for portable barbecues or compact patio heaters, while larger cylinders are suited for more frequent use or higher heat output. Most suppliers offer refill services, allowing you to exchange empty bottles for full ones, which reduces waste and ensures you’re always ready to go when the weather allows.

Before buying or replacing a cylinder, it’s important to check your appliance’s gas input rating and regulator compatibility. Using the correct size and connection is essential for both safety and performance. If you’re unsure, your gas supplier or appliance manufacturer can confirm the correct setup.

Where to Get Patio Gas in the UK

Patio gas can be purchased or exchanged through most major gas suppliers, garden centres, hardware stores, and DIY retailers. Popular suppliers include Calor and Flogas, who offer nationwide distribution and bottle exchange services. When buying patio gas for the first time, you may need to pay a cylinder hire charge, which covers the cost of using the bottle itself. After that, you only pay for the refills.

Many outdoor appliance retailers also stock patio gas or offer starter kits with the correct regulator and hose included. Always make sure you’re buying from a registered supplier to guarantee safety, proper filling, and compliance with current gas storage regulations.

Why Patio Gas Is Ideal for UK Weather

Patio gas is designed to perform reliably in a wide range of outdoor temperatures, which makes it particularly well suited for the UK’s unpredictable weather. Unlike butane, which can struggle to vaporise in colder conditions, propane continues to perform efficiently even when temperatures drop below freezing. This means that patio gas provides consistent output on chilly spring evenings, autumn afternoons, or during winter garden use — especially for outdoor heaters in pub gardens or covered terraces.

This cold-weather reliability is a key reason why propane is chosen for patio gas cylinders. Whether you're cooking outdoors in summer or heating a space during colder months, you can depend on patio gas to deliver steady heat when you need it most.

The Role of the Clip-On Regulator

One of the defining features of patio gas is its compatibility with a 27mm clip-on regulator. This system is designed for ease and safety, allowing users to attach and remove the gas cylinder without tools. The clip-on mechanism includes a safety lock and pressure control, helping prevent leaks and maintaining a steady flow of gas to the appliance.

For domestic users, the simplicity of the clip-on fitting makes switching bottles quick and stress-free. It reduces the risk of incorrect installation, which can be a concern with screw-on regulators. When changing cylinders, the clip-on system ensures that you don't need to handle valves or pressure settings manually — it locks securely into place with an audible click.

Patio Gas in Commercial and Hospitality Settings

Patio gas isn't just for home use. It’s widely used in commercial outdoor settings such as pubs, restaurants, beer gardens, hotels, and event venues. Outdoor heaters and fire pits powered by patio gas help businesses extend their usable outdoor space year-round, especially during colder evenings or in winter. In many cases, these appliances are vital for meeting demand in smoking areas, al fresco dining zones, or pop-up venues.

Because patio gas cylinders are portable and refillable, they offer a practical solution where permanent heating systems aren't viable. The ability to move heaters or barbecues to different locations makes them ideal for temporary setups, outdoor events, and hospitality spaces that change layout frequently.

Environmental Considerations

Although patio gas is a fossil fuel, it produces fewer emissions than coal or oil and burns more cleanly than wood or charcoal. It releases very little particulate matter and produces lower levels of carbon dioxide compared to other solid fuels. This makes it a relatively efficient choice for outdoor heating and cooking, especially where smoke or soot would be an issue.

Some suppliers now offer bio-propane, a renewable alternative made from sustainable sources such as plant waste or cooking oil. Bio-propane can be used in place of standard patio gas without modifying your appliance, offering a lower-carbon option for environmentally conscious consumers.

Safety and Storage Tips

Storing patio gas safely is essential. Cylinders should be kept upright, in a well-ventilated area, and away from heat sources or open flames. If stored outside, make sure they are protected from extreme weather and positioned on a stable surface. Avoid keeping cylinders in enclosed areas such as garages or sheds without proper ventilation.

Before connecting a new bottle, always check the hose for signs of wear or cracking and ensure the regulator is functioning properly. If you ever smell gas or suspect a leak, turn off the supply immediately and contact a qualified gas engineer or your supplier for assistance.

Final Word

Patio gas is a convenient and reliable fuel source designed for outdoor living. Whether you’re firing up a barbecue, warming a patio area, or entertaining in cooler months, patio gas provides instant, clean heat with minimal hassle. Its simple connection, safe operation, and all-weather performance make it a go-to option for UK households and hospitality venues alike. Choosing the right bottle and setup ensures you get the most out of your outdoor space — safely and efficiently.
