DEFRA stands for Department for Environment, Food and Rural Affairs and they handle regulations and policies regarding the environment, farming and food. Defra approved stoves have tested rigorously to ensure that they comply with the strict regulations of the government regarding emissions of smoke during operation. They're also designed to burn authorised fuels like wood and coal more efficiently, which means they produce far fewer pollutants.
This is a good thing for those living in a Smoke Control Area because the law currently prohibits the emission of smoke within such areas unless using an DEFRA approved stove and an authorised fuel. In the past it was possible to install an non Defra approved wood stove in a Smoke Control Area, as long you used only approved fuels. In January 2022, the laws will change and non-approved stoves aren't allowed to be used unless they're equipped with a secondary or secondary system that reduces the production of particulate matter, nitrogen oxides, carbon dioxide and organic gaseous substances.
Our Defra approved ranges are also equipped with a mechanism to prevent you from closing down the top air vent completely. This could lead to the fire to ignite and release smoke into your home. Instead, these stoves come with an adjustable air flow that will allow you to open the top vent just a bit and still keep a safe and efficient burn.
Another benefit of buying a Defra approved stove is that it can be fitted with a 5 inch chimney liner. This is crucial because the majority of codes require a chimney to be at least 5 inches in diameter.

Stoves that are Defra Approved will usually be identified by the an 'SE' logo that stands for Smoke Exempt.
A stove that is Defra-approved differs from a typical multifuel stove because it has secondary air vents which pre-heat air prior to it entering the firebox. This pre-heated air helps ensure that all the fuel is ignited and burned, leading to an efficient combustion process. It also prevents the build-up of soot in the chimney and keeps it from becoming blocked. Defra stoves also have internal baffle plates that help to regulate the flames and ensure an evenly distributed heat distribution.
The use of non-Defra-approved stoves in smoke controlled areas could result in substantial fines from the UK government's Department for Environment, Food and Rural Affairs (Defra). If you wish to avoid being accused of being prosecuted by Defra, only use a DEFRA approved stove that has been inspected in accordance with government criteria.
DEFRA stoves can also be called Clean Burn stoves. They can be used with all kinds of fuel, but are especially suited to dry hard and soft wood. The air vents can't be closed completely, meaning there is always oxygen available to support the clean combustion.
This technology is not just in line with the current standards for air quality of the government as well as with the future Ecodesign requirements that will be in effect in 2022. Many of the Stovax wood burning and multi-fuel stoves we offer will carry this SIA Ecodesign Ready mark which confirms that they meet these new stricter emissions standards.
