What is a Defra Approved Wood Burning Stove?

If you live in a zone of smoke control then you must buy a DEFRA exempt stove. A DEFRA exempt (or SE) stove permits you to burn wood legally in a smoke-controlled area.

The stoves are independently tested for the lowest emission possible. Stoves with this status are often branded with the 'Defra-approved logo on their specifications or name.

Approved for Smoke Controlled Areas

Many people believe that living in a Smoke Control Area means you can't use a wood-burning stove however this isn't true. Most cities and large towns are within a smoke control zone, but that doesn't mean they can't use a wood burning stove. It just means they have to burn approved fuels in their stove (usually briquettes). The Defra-approved stove is a wood-burning stove that has been thoroughly tested to ensure that it meets certain criteria in terms of the emissions it generates when burning approved materials. It can therefore be legally used in a smoke control area.

The Defra Logo is widely used in the industry, and a lot of stoves are marked with the SE after their names to indicate they are smoke-free.

This is important because it will ensure that the smoke from the stove does not escape through the chimney and into your home.

Approved for Smokeless fuels

A DEFRA approved wood burning stove, also known as a DEFRA exempt stove, is the only type of stove that you can put in a smoke control area in the event that you intend to make use of it for solid fuel (wood or wood that is well-seasoned). The government tests these stoves to ensure that they don't emit excessive smoke and that they are only suitable for use with approved fuels.

The difference between a DEFRA approved stove and a non-approved one typically is very small. Many modern stoves can easily be converted to DEFRA conforming with a kit that is supplied by the manufacturer and then fitted within a matter of minutes. This is because the Defra approved stove has to undergo rigorous testing and must be restricted to the amount of smoke it can generate.

To ensure that these limitations are maintained during testing the stove must be able to limit the combustion air supply so that it does not deplete itself of oxygen, which can cause it to smolder. This is done by a mechanism inside the stove that allows an air pocket into the firebox during combustion which is typically hidden within the stove and underneath the base of the fire box.

Many older wood stoves emit large amounts of particulate matter. These can cause or worsen asthma attacks, respiratory issues and heart problems. It is therefore important to buy a wood stove that is in compliance with strict emission standards established by the Environmental Protection Agency. Look for the "EPA 2020 Certified Label" which indicates that the stove is in compliance with the emission limits currently in place.

If you purchase a stove that is not EPA certified and you reside in a smoke control area it is necessary to have it recertified before you can use it. It is costly and time-consuming, but the law requires it. Additionally homeowners who sell a house with a wood stove that isn't certified could be liable for clean air tax credits as well as fines.

Most modern stoves can be altered to become Defra approved using an adjustment kit or a kit that the installer provides. The major difference between DEFRA approved stoves and those that aren't is the combustion air control system, which regulates the amount of air that flows through the stove operating normally. The modification will usually be made on the underside of the firebox or within the base.

Some manufacturers will produce two versions of their wood stoves one that is Defra approved and the other that is not. This is due to the process of putting a stove through the stringent Defra tests is very expensive, so to help recoup some of the cost, they'll offer the non-approved model at a lower price. The DEFRA-approved model will have been subjected to the modification of the combustion air as part of the test procedure.

Prior to the Clean Air Acts, residential homes could burn any fuel they wanted to, leading to large amounts of smoke emissions. This led to health issues.
