Thinking about transforming your outdoor living space with a premium volcanic pumice fireplace or outdoor kitchen? To help you prepare for a seamless installation, we’ve compiled the answers to the most common questions regarding safety clearances, UK planning laws, and environmental regulations.
No. Due to the substantial structural weight of these premium volcanic pumice packages—which range from 460kg up to 1,490kg fully built—they must never be placed on timber decking.
Instead, they require a flat, solid foundation. We strictly recommend a minimum 100mm thick reinforced concrete base to guarantee the completed structure won’t sink or slant over time.
Because volcanic pumice is a highly effective, natural insulator, the exterior of the fireplace remains safe to touch. However, a precise buffer zone must be maintained between the structure and any combustible materials:
The chimney flue must completely clear the height of your pergola canopy to ensure exhaust smoke and sparks disperse safely away from your seating area.
If your design requires extra height to clear an overhanging beam line safely, additional chimney blocks can be purchased separately and added to the vertical stack during assembly. We also highly recommend adding a Rain Cap / Wave canopy to maintain a reliable upward draft and block weather down-drafts.
For the vast majority of residential homes, permanent brick or stone barbecues and outdoor fireplaces fall under Permitted Development rights (similar to garden outbuildings or enclosures). This means they do not require a formal planning application, provided your project meets specific layout criteria.
This depends entirely on the total height of your completed structure (including the chimney capping):
Once your fireplace is positioned safely past the 2-metre boundary zone, your Permitted Development allowances increase:
Note: If your space is restricted and you cannot move a chimney taller than 2.5m at least 2 metres away from a boundary, you must submit a formal Householder Planning Application to your local council before starting construction.
Yes. If you plan to install your garden fireplace as a standalone, freestanding unit (rather than building it flush against a solid masonry wall or as part of a fully supported outdoor kitchen layout), you must carefully consider the maximum height for wind safety:
Yes. While the UK Clean Air Act regulates chimney smoke inside urban areas, unroofed outdoor garden fireplaces and barbecues are broadly exempt from domestic indoor chimney restrictions. However, you can still face local enforcement if your fireplace creates what the law defines as a “Statutory Nuisance.”
Under Section 79 of the Environmental Protection Act, if smoke, ash, or persistent fumes from your garden fire regularly blow directly into a neighbor’s property—preventing them from opening their windows, sitting outside, or hanging out laundry—the local council can issue an Abatement Notice.
To avoid this, always position your fireplace where prevailing winds won’t push smoke directly toward neighboring windows, and extend your chimney height if necessary to discharge smoke cleanly upwards.
To ensure a clean, efficient burn, you should strictly use clean, dry, and seasoned wood logs—ideally labeled with the Woodsure “Ready to Burn” logo, which certifies a moisture content below 25%.
Never Burn: Treated or painted waste wood, old pallets, plastic, or household rubbish. Burning these materials releases volatile, toxic chemicals into the air, creates heavy dark smoke, and leads to an immediate buildup of corrosive tar within your chimney structure.

Sirius stove / Permeter Smooth Air brochure
The Permeter Smooth Air Chimney System provided with the Sirius stove is a steel chimney with air supply offers great flexibility and flexible placement.
All Sirius models are approved by the highest European standards for air independent use. This allows the combined usage with ventilation systems in modern buildings and guarantees a healthy indoor environment.
Schiedel Permeter Smooth Air chimney is constructed with a separate inlet-duct ensuring that the stove is supplied with the optimal amount of combustion air from the top of the pipe. The double insulated pipes avoid condensation.
