The difference between the differences between a DEFRA approved stove and one that isn't is usually very little. Modern stoves can be converted to DEFRA approved contemporary stoves certified by an approved kit supplied by the manufacturer and installed within a matter of minutes. This is due to the fact that Defra approved appliances must pass very strict tests and are restricted in the amount of smoke they can produce.

To ensure that the restrictions are kept the stove has to be able to limit its combustion air so that it doesn't starve itself of oxygen and cause it to smolder. This is accomplished by an opening mechanism that lets an air pocket in the firebox when it's burning. It is usually concealed in the stove or under the base of its fire box.

Before the Clean Air Acts were brought in homes for residential use, homeowners could burn any type of fuel they wanted which resulted in large amounts of smoke emissions and health problems. To stop this, Defra created Smoke Control Areas which meant that homes in residential areas couldn't emit any smoke from their wood burners or multifuel stoves unless the appliance was Defra certified to burn only fuels that were authorised, such as manufactured smokeless coals and anthracite.

Defra approved SE (Smoke-Exempt) Stoves have been subjected to rigorous tests to demonstrate that they can safely burn approved fuels within a Smoke Control Zone. They accomplish this by using the latest combustion technology which continually delivers a minimum amount of secondary air to the firebox, to ensure that even if the stove is used with authorised fuels such as anthracite or manufactured smokeless coals it can still meet Defra's regulations for Smoke Control Areas.
