What Are Defra Approved Stoves?

Also referred to as Defra Exempt Stoves and Smoke Control Approved Stoves, these stoves are typically designed to burn Defra approved smokeless fuels, such as Anthracite ovals. However, they won’t be suitable to use with wood.

To qualify as Defra exempt, a stove has to be able to pass laboratory tests for air controls and flue draught. These tests are different from real world conditions.

Clean Burn Technology

A DEFRA-approved stove is a multifuel or wood-burning stove that has been through a rigorous test developed by the UK Government Department of Environment, DEFRA approved low emission Stoves Food and Rural Affairs.

Smoke Controlled Areas

Smoke Control Areas are defined in the majority of UK cities and towns. If you reside in one of these areas you’ll require an exempt DEFRA wood stove or multifuel stove. These stoves are designed to adhere to the Clean Air Act regulations, and have been tested for smokeless combustion.

A DEFRA approved stove is designed using Clean Burn Technology, which is the reason they are smoke-free. This is accomplished by forcing a continuous supply of oxygen into the combustion chamber until the fuel is consumed. This means the fire can’t be shut off like a traditional stove and therefore it will continue to burn at a low level until the fuel is completely consumed and the flue gasses are exhausted.

This allows you to use the stove legally in a Smoke Control Area, with approved fuels. These include wood and manufactured smokeless fuels such as anthracite, smokeless briquettes, and firelogs. This is contrary to non-Defra stoves which are only permitted to be used in a Smoke control Area provided they are fitted with a special smoke control kit.

Smokeless Fuels

When choosing a stove with smokeless fuels, there are numerous things to take into account. The stove must be approved by DEFRA to be used in smoke-controlled areas.
