Choosing a Defra Exempt Wood Burner

The majority of UK cities and towns are classified as Smoke Control Areas so if you reside in one of them and wish to install a wood burning stove, then you'll require a Defra exempt stove. You can identify them by their approved logo from the Defra.

What is what is a Defra exempt stove?

A Defra Exempt stove is a wood-burning domestic heating device that has passed the tests set out by the Department for Environment, Food and Rural Affairs. The Defra Exempt Label is only used for stoves that have been independently tested and have met strict standards regarding emissions. Defra exempt stoves are able to be used in Smoke Control Areas.

You cannot burn wood without a DEFRA approved stove when you live in an area where smoking is controlled. If you install a non-DEFRA-approved stove in a smoke control zone, you could be in violation of the Clean Air Act and could be charged.

From the outside, there's very little difference between the Defra approved stove and one that has not been given this status. There are a few ways stove makers can do to make their appliances exempt from DEFRA. The most obvious distinction is that the burners on a DEFRA approved stove are made not to starve the flame of oxygen, because this could cause it to smoulder and create excessive quantities of smoke.

To avoid this, stove manufacturers usually adjust the air vent at the top of a Defra approved stove. This will prevent you from being able shut the vent completely, as this would cut the air supply to the fire. The adjustment is usually an incredibly small screw located on the top of the stove, underneath the stove's base or on the back of the stove.

Stoves that are Defra Exempt also tend to be multifuel stoves and may therefore be used to burn different types of fuels alongside wood. This is a great choice if you reside in an area that is designated as a Smoke Control Zone but you don't want to be bound by the restrictions of only using approved fuels. Some stoves with Defra exemptions can be equipped with 5" liner for wood burning (if the manufacturer doesn't insist on the larger size). This is good news for those who are planning to install wood-burning stoves in their homes, but are concerned about local regulations on smoke.

What are the benefits of a Defra approved stove?

To get Defra approval, stove makers have to modify their appliances to limit the amount of air that can be lost during the burning process. Typically the air control on top will be modified to prevent it from being shut all the way. If you shut off the air supply too much, it can cause the stove to smolder instead of burning properly. This will lead to unpleasant smoke.

What is the difference between a Defra Approved Stove and a Non-Defra Approved Stove?
