The Last Fire Pit You'll Ever Need to Buy

A fire pit turns a cold garden evening into something worth staying outside for. But with wood, gas and smokeless models on the market, plus a dozen shapes and sizes, picking the right one takes some thought. This guide covers fuel types, materials, sizing, UK rules and what actually matters when you're spending your money.

What Is a Garden Fire Pit?

At its simplest, a fire pit is a contained bowl or basin that holds a fire safely off the ground. Some sit on short legs. Others form the centre of a table, so you get warmth and a surface to rest a drink on at the same time. The design decides how much heat you get, how much upkeep it needs and whether you can use it at all if you live in a built-up area.

Fuel Types: Wood, Gas and Smokeless

Fuel is the first decision to make, because it affects everything else — cost, smell, cleaning and whether you're allowed to use it where you live.

Wood Burning Fire Pits

Wood burning fire pits give the crackle, sparks and smell that most people picture when they think of a fire pit. They're usually the cheapest to run, since logs cost less than gas bottles over time. The trade-off is smoke, ash and the need to store dry fuel somewhere. Only burn seasoned or kiln-dried wood — wet logs smoke heavily and burn poorly.

Gas Fire Pits

Gas fire pits run on propane or, less often, mains natural gas. Light it, adjust the flame with a dial and switch it off when you're done — no ash, no smoke, no waiting for logs to catch. They cost more upfront and the fuel isn't as cheap as scrap wood, but for anyone in a smoke control area (more on that below) gas removes the legal question entirely. A standard 6kg or 13kg propane bottle will run most garden models for several hours.

Smokeless Fire Pits

Smokeless fire pits still burn real wood, but they're built with a double wall. Cool air is drawn in through vents at the base, heats up as it travels through the gap between the two walls, then gets pushed back over the fire near the top rim. This preheated air reignites the smoke and unburned particles before they escape — a process called secondary combustion. No wood fire is ever completely smoke-free, but a well-designed smokeless pit cuts it dramatically, especially once the fire's established. You still need dry fuel; damp logs overwhelm the system and smoke returns.

Materials Explained

The material affects weight, lifespan, heat retention and how much maintenance you'll be doing.

• Steel: Steel firepits are the most common option. Mild steel is affordable but needs a rust-resistant coating. Stainless steel resists corrosion well and suits coastal gardens. Corten steel (also called weathering steel) develops a rust-coloured patina over 6 to 18 months, which then protects the metal underneath — it needs no painting, though it can shed some rust-coloured runoff onto light-coloured paving during that first year.
• Cast iron: heavy, slow to heat and slow to cool, so it keeps radiating warmth long after the flames die down. It's prone to rust and can crack under sudden temperature swings, so it needs more upkeep than steel.
• General metal: if you'd rather browse by finish and style than get into the technical differences, the full metal fire pits range covers steel, cast iron and mixed-metal designs side by side.
• Rattan: rattan fire tables pair a synthetic woven rattan surround with a gas or bio-ethanol burner set into the top. They look like garden furniture first and a fire feature second, which suits patios where you want the pit to double as a coffee table.

Understanding BTU: How Fire Pits Are Rated for Heat

BTU stands for British Thermal Unit — the amount of energy needed to raise one pound of water by one degree Fahrenheit. In plain terms, it's the measurement used to compare how much heat a gas fire pit puts out. Higher BTU means more warmth and a bigger flame, but also faster fuel use and a larger required clearance from anything flammable. A model rated around 50,000 BTU sits at the higher end for garden use — strong enough to heat a decent-sized patio on a cold evening. Browse the 50,000 BTU fire pits range if you want serious heat output for larger gatherings. For a smaller patio or balcony, a lower BTU rating is usually plenty and burns through gas more slowly.

Shapes and Sizes

Fire pit size should match your outdoor space, not just your budget. A pit that's too large for a small patio eats up the whole area and forces seating too far back to feel the heat.

• Round fire pits: the classic shape. A circular design spreads heat evenly in every direction, which makes seating arrangement simple. See the full round fire pits range.
• Small firepits: ideal for compact patios, balconies or courtyard gardens where space is tight. Check out small firepits for models that don't dominate a small area.
• 32-inch fire pits: a popular mid-size choice, big enough for a small group without needing a huge garden. View the 32-inch fire pits collection.
• 40-inch fire pits: a step up in size, suited to larger patios and bigger get-togethers. Browse 40-inch fire pits for the wider size range.

Standalone Pits, Tables and Combination Sets

Beyond fuel and material, fire pits come in different formats depending on how you plan to use your garden space.

Firepit Tables

Firepit tables build the flame into the centre of a table surface, usually gas-powered with a lid or lava rock covering to convert it back into a normal table when not lit. This suits smaller gardens where one piece of furniture needs to do two jobs.

Complete Seating Sets

If you'd rather buy the whole setup in one go, firepit table sets and firepit chair sets pair the pit with matching seating, so everything's built to the right height and distance from the flame. For a snugger arrangement around a corner of the patio, corner firepit chairs wrap seating around the pit in an L-shape rather than a full circle.

Rising Table Firepits

A clever hybrid: the fire pit sits inside a low coffee table, then a mechanism raises the flame up on a pole for evening use and lowers it back down when you want a normal table surface. Have a look at rising table firepits if flexible use of the same furniture matters to you.

Firepit Grills

Some fire pits double as cooking equipment. Firepit grills include a removable cooking grate over the flame, so you get a barbecue and a fire feature in one unit — useful if patio space is limited.

Portable Fire Pits

For camping trips, caravan holidays or simply moving the fire around the garden as the season changes, portable fire pits fold down or come with carry handles and weigh far less than a permanent steel bowl.

UK Rules and Regulations: What You Need to Know

Fire pits are legal in UK gardens. That said, several rules affect what and how you can burn.

Smoke Control Areas

Large parts of London and sections of cities including Manchester, Birmingham and Glasgow fall inside what's called a smoke control area (SCA). In these zones, burning wood and coal is generally prohibited unless you use an exempt appliance. Councils can issue fixed-penalty notices for households emitting smoke from unauthorised fuel in an SCA — typically in the £175 to £300 range. You can check whether your address falls inside one using the DEFRA postcode lookup tool, which covers England, Scotland and Wales (Northern Ireland has separate rules).

The Wet Wood Ban

Since 2021, selling wood with a moisture content above 20% in volumes under 2 cubic metres has been illegal in England. Look for the "Ready to Burn" logo on bagged logs — it confirms the wood meets the moisture limit and is legal to burn even inside an SCA. A cheap moisture meter from a hardware shop will confirm loose or bulk-delivered wood before you burn it.

Nuisance to Neighbours

Even outside a smoke control area, persistent smoke drifting into a neighbour's garden can count as a statutory nuisance under the Environmental Protection Act 1990. Councils can issue an abatement notice ordering you to stop, and ignoring it can lead to a fine. In practice, this only tends to be enforced where smoke is frequent, heavy and clearly affecting someone else's use of their property.

If You're in a Smoke Control Area

The simplest fix is switching fuel entirely. A gas fire pit sidesteps the wood-smoke question completely — you're burning propane through an enclosed burner, so there's no ash, no embers and no fuel-type restriction to worry about. See the gas fire pits range if this applies to you.

Safety: Decking, Clearance and Base Materials

Where you put your fire pit matters as much as which one you buy.

• Clearance from buildings: keep a fire pit at least 3 metres from your house, fences, sheds or overhanging branches. Larger, higher-BTU gas models need more room — check the manufacturer's stated clearance before you buy.
• Decking: wood decking and fire pits don't mix well. Sparks, embers and prolonged heat exposure can scorch or weaken timber over time. Composite decking is worse — it can soften at surprisingly low temperatures. If you must use one on decking, a rated heat-proof mat underneath is essential, and gas models are the safer choice since they don't throw sparks.
• Base surface: paving slabs, concrete or gravel are the safest bases. Never light a fire pit directly on grass or near dry vegetation.
• Weather: skip lighting up on windy days. Wind carries embers further than you'd expect and can spread a fire quickly across dry ground.
• Supervision: never leave a lit fire pit unattended, and make sure it's fully out — not just low — before you go inside.

How to Choose the Right Fire Pit for Your Garden

Work through these questions before you buy:

• Do you live in a smoke control area? If yes, lean towards gas.
• How much patio space do you actually have? Measure it before picking a size — a 40-inch pit needs more clearance than it looks like in a product photo.
• Do you want a dedicated fire feature, or something that also works as a table or barbecue?
• How much maintenance are you willing to do? Corten and stainless steel need almost none. Cast iron and mild steel need more regular attention.
• Will you move it often? If so, weight matters more than heat output.

Maintenance and Care

• Empty ash regularly — a thick layer blocks airflow and makes wood-burning and smokeless pits smoke more, not less.
• Cover steel and cast iron models when not in use to slow rust.
• Wipe stainless steel with mild detergent and dry it fully to avoid water marks.
• Store gas bottles upright, away from direct sun, and disconnect them when the pit isn't in use for extended periods.
• Check hoses and regulators on gas models each season for cracks or wear.

Frequently Asked Questions

Are fire pits legal everywhere in the UK?

Yes, with conditions. Wood-burning is restricted in smoke control areas unless you use Ready to Burn fuel or an exempt appliance. Gas fire pits avoid this issue entirely.

What's the difference between a smokeless fire pit and a normal one?

A smokeless pit uses a double-wall design to preheat air and reburn smoke before it escapes, through secondary combustion. A standard open pit has no such system, so smoke rises freely.

Can I put a fire pit on my decking?

Gas models with a rated heat-proof mat underneath are the safer option. Wood-burning pits are best avoided on wood or composite decking due to sparks, embers and heat damage.

What size fire pit do I need?

For a small patio or balcony, look at small firepits. For an average garden, 32-inch models strike a good balance. For larger groups and bigger gardens, 40-inch or larger designs give more heat and seating room.

Is wood or gas cheaper to run?

Wood is usually cheaper per use if you can source or season logs yourself. Gas costs more per session but comes with no cleaning, no smoke and instant on-off control.

Whatever you choose, match the fire pit to your space, your local rules and how much upkeep you're prepared to do. Get those three right and you'll get years of use from it.
