Choosing a Defra Exempt Wood Burner
Smoke Control Areas are the most common classification for UK towns and cities. If you reside in a Smoke Control Zone and want to install an appliance, you'll need a Defra approved stove. You can identify them by their Defra approved logo.

What is an Defra Exempt Stove?
A Defra Exempt Stove is a domestic heating appliance that burns wood and has passed the tests conducted by the Department for Environment, Food and Rural Affairs. The Defra Exempt Label is only applied to stoves which have been independently tested, and meet strict criteria regarding emissions. Defra exempt stoves are able to be used in Smoke Control Areas.
You can't burn wood without a DEFRA approved stove when you live in an area where smoking is controlled. Installing an non DEFRA approved stove in a smoke control zone is a violation of the Clean Air Act. You could be prosecuted.

There are however a few things that stove makers do to make their products DEFRA Exempt. The most obvious distinction is that the burners on a DEFRA approved stove are designed not to starve the flame of oxygen, because this could cause it to smoulder and produce excessive amounts of smoke.
To avoid this, stove manufacturers typically adjust the top air vent on an Defra approved stove. This will prevent you from being able to shut the vent completely down, as it would cut off the supply of air to the fire. The adjustment is usually a small screw located inside the front top of the stove, underneath the stove's base or on the back of the oven.
