The Simpa 180L is a heavy-duty garden incinerator designed for larger clear-outs, woody prunings and hedge trimmings. Its large capacity, galvanised steel body and 36 ventilation holes make it a practical choice for gardeners who regularly need to burn suitable dry garden waste.
In this review, I cover why it is my top extra-large option, how it compares with other large incinerators, and what to consider for safer, more efficient use.
Before using a garden incinerator: Check your local council and, where relevant, your allotment rules. Burn only suitable, dry garden material, avoid causing a smoke nuisance or creating a road hazard, and never burn household rubbish, plastics, rubber, painted timber or treated wood.

Key Features of the Simpa 180L Reviewed
Whether you’re managing a large garden or tackling seasonal clear-outs, the Simpa 180L incinerator offers durability, convenience, and top-tier performance for eco-conscious homeowners. Not sure if you need something as big as the Simpa 180L? Check out our top pick for the best garden incinerator for everyday use.
1. Huge 180L Capacity
This extra-large garden incinerator handles serious waste. If you’re clearing garden waste regularly as I do, it saves time and effort. The massive 180-litre capacity means fewer trips, longer burn sessions, and less hassle overall. It’s a great fit for gardeners tackling heavy-duty pruning or seasonal clear-outs.
2. Durable Galvanised Steel Build
Built to last through all seasons. Made from rust-resistant galvanised steel, this heavy-duty garden incinerator stands up to high heat and rough weather—perfect for year-round garden use in the UK.
3. Excellent Ventilation Design
Burns hotter, faster, and cleaner. Thanks to smartly placed air holes around the base and sides, the airflow is spot on. You get hotter fires, quicker burns, and way less smoke. That’s what you want in the best garden incinerators—fast, clean, and efficient combustion.
4. Locking Chimney Lid
Safer and smarter smoke control. The chimney-style lid locks in securely and directs smoke upwards, which is a lifesaver if you’re burning close to fences or sheds. It helps manage flames and airflow too, making it safer and more effective for home use.
5. Reinforced, Stable Base
Won’t wobble or scorch your patio. With strong feet and a toughened base, this large metal incinerator stays put—even when the wind picks up. Plus, its raised design keeps the heat off your lawn or patio, protecting surfaces while boosting airflow underneath.
Simple Assembly
The three legs need attaching before first use, with the required fittings supplied. Assembly is straightforward, but the incinerator is not completely ready to use straight from the box.
All in all, the Simpa 180L Extra Large Garden Incinerator is a proper workhorse. It’s tough, roomy, and ideal for gardeners who need a reliable, no-fuss way to deal with bulky garden waste.
Value for money: Prices for garden incinerators change regularly, so compare the live cost rather than relying solely on capacity. The Simpa generally costs more than a basic 80–90L burner, but provides substantially more room, a locking chimney lid and a larger ventilated drum.

Simpa 180L Review – Is This the Best Extra Large Garden Incinerator for You?
As a working gardener, I burn waste almost every week — and when you’re dealing with serious clippings, hedge trimmings, and woody branches, size really does matter. One of my regular clients recently switched to the Simpa 180L extra-large garden incinerator, and it’s made our clean-ups far quicker and more efficient. After using it myself, I can genuinely recommend it.
To make sure you get the full picture, I’ve also gathered user reviews and insights from others who’ve tested this incinerator in real garden settings.
What Customers Loved
- Massive Capacity – The 180-litre size is the real game-changer here. Users consistently praised how much waste it can handle in a single burn — perfect for seasonal clear-outs, regular pruning jobs, or dealing with a backlog of compost overflow.
- Quick, Clean Burns – Thanks to well-placed ventilation holes and a chimney-style lid, this model gets excellent airflow. That results in faster burns, minimal smoke, and less leftover ash.
- Durable Construction – The galvanised steel build holds up well under heat and repeated use. Most reviews noted no signs of warping or early rusting — a big plus for heavy-duty garden work.
- Comfortable Height – The raised design makes loading easier, especially when tipping in garden waste from a barrow. It’s also more stable on uneven ground compared to smaller incinerators.
Things to Keep in Mind
- Some Assembly Needed – A few buyers mentioned that it requires light assembly out of the box. Nothing too technical, but you’ll need a screwdriver and 10–15 minutes.
- Cosmetic Colour Change – Like most metal incinerators, this one darkens with use. That’s expected and doesn’t affect its performance.
- Loose-Fitting Lid – Some users found that the lid didn’t sit perfectly flush. A quick fix with a small weight or adjusting the fit usually solves it.

FAQs – Choosing the Best Extra Large Garden Incinerator for Your Needs
The Simpa 180L Garden Incinerator is one of the best extra-large garden incinerators on the market. Its massive 180-litre capacity, tough build, and reliable burn performance make it ideal for eco-conscious gardeners tackling heavy-duty waste.
Yes, if you follow safety tips. Always place your garden incinerator on a flat, non-flammable surface. Keep it away from fences, sheds, and trees, and avoid burning in windy weather. Never leave it unattended while in use.
It is best not to. Wet leaves, grass and fresh clippings tend to smoulder, producing more smoke while burning slowly and inefficiently. Allow suitable garden material to dry before burning, and compost or recycle it wherever practical.
Current council guidance consistently recommends burning only dry garden material.
Yes — and it helps a lot. The chimney-style lid boosts ventilation, maintains consistent heat, and pushes smoke upward, keeping it out of your face.
Galvanised steel. This offers excellent rust resistance and durability — ideal for UK gardens exposed to rain and moisture.
Eventually — yes. Galvanised steel holds up well, but not forever. Store it in a shed or under a waterproof cover to extend its lifespan.
It depends. Allotment rules vary. Some allow large garden incinerators, others ban open burning. Always check with your site manager first.
Large gardens and heavy users. If you’re clearing trimmings, branches, or weeds weekly, this incinerator will save you time and hassle.
Only add clean wood ash, and use it sparingly. Do not compost ash produced from household rubbish, treated or painted timber, plastics or mixed unsuitable materials. Wood ash is alkaline and contains soluble salts, so excessive amounts can damage plants and raise the compost’s pH. Avoid using it around acid-loving plants.
The RHS recommends adding wood ash only occasionally—roughly one light layer for every 15cm of other composting material—and mixing it in thoroughly.
Once cooled, empty out the ash and wipe away any remaining moisture to prevent rust. For long-term use, apply a coat of high-temperature metal paint to any exposed areas — especially if using a heavy-duty steel incinerator.
Larger incinerators offer more burn capacity and airflow but need more space. Small ones are better for tight gardens or light use.
Yes, especially if you burn damp material, thicker branches, or garden waste weekly. They last longer and resist rust better.
All in all, the Simpa 180L Extra Large Garden Incinerator is a dependable, heavy-duty workhorse. It’s built for serious gardeners who need to clear waste quickly and cleanly — without the hassle.
Final Verdict: Is the Simpa 180L Worth It?
The Simpa 180L is a strong choice for gardeners who regularly need to burn larger volumes of suitable dry garden waste. Its generous capacity, galvanised steel construction and 36 ventilation holes make it well suited to hedge trimmings, woody prunings and seasonal clear-outs.
Why I Recommend It
- Large 180-litre capacity
- Sturdy galvanised steel body
- Good airflow through 36 ventilation holes
- Locking chimney lid
- Best suited to larger gardens and heavier clear-ups
Some simple assembly is required, and the steel will eventually weather if left exposed. However, for gardeners who genuinely need the extra capacity, it offers a practical balance of size, durability and ease of use.
