Defra exempt stoves are designed for use in smoke control areas in the UK. These Defra exempt stoves have been independently tested to meet strict criteria on emissions, which then qualifies the stove to be exempt from the requirements of the Clean Air Act.
If you live in a smoke-controlled zone, then the only wood burning domestic heating appliance it is legal to install and burn, is a Defra exempt stove.
Defra Exemption has therefore enabled homeowners living in urban areas to share in the lifestyle benefits enjoyed by those living in the countryside.
It is worth noting that the particulate matter (PM) emission limits for Ecodesign compliant wood burning stoves and fireplaces is 55% lower than for Defra Exempt stoves. This is why the Mayor of London has recommended the installation of Ecodesign Ready stoves, that are also Defra Exempt, which the majority of Ecodesign Ready stoves are.
Ecodesign Ready stoves must currently also be Defra exempt to be used in smoke control areas.
The SIA maintains a product listing of appliances that its members have certified meet the forthcoming Ecodesign regulations. Click here to see a list of SIA Ecodesign Ready stoves.
