Stove makers like Arada, Burley Parkray & Stovax are working hard to develop clean-burn technology. This has led to the development of Defra-approved stoves which not only reduce the amount of pollutant emissions in the air, but also reduce the amount smoke produced during combustion. Defra approved stoves now include secondary and tertiary combustion systems to further reduce emissions and make use of fuel more efficiently and make for a much more sustainable and environmentally eco-friendly method of heating your home.
It is crucial to know that a stove that is Defra-approved can be used to burn wood and solid fuels such as coal fires, household coal and high petroleum-based fuels, and Petrol Coke.

When you are purchasing wood to burn in your Defra approved stove, we recommend that you only purchase dry properly seasoned logs, properly seasoned and splits. We also recommend using only firewood marked with the Ready to Burn logo. This indicates that the wood is treated to have a an extremely low moisture content, to avoid excessive smoke production.

It's important to note here that non-Defra stoves can still be used in smoke-controlled areas, but they must only be used to ignite authorised fuels like anthracite. If you make use of them to burn various wood types or other solid fuels that are flammable, they could emit excessive smoke, which could result in an order for a fire violation.
Stoves that are Defra Approved often have the Defra logo on their descriptions of products. They may also be referred to as SE (smoke exempt) or simply as DEFRA stoves by their makers.
In order for a stove to be approved by Defra the stove must meet strict performance and emission requirements that are set by the Department for Environment Food and Rural Affairs. They have passed rigorous tests to ensure low emissions and high efficiency.
