Information About DEFRA

DEFRA, the Department for Environment, Food & Rural Affairs, is a UK government body responsible for shaping policies around the environment, rural affairs, and food. They play a crucial role in meeting the requirements of the Clean Air Act 1993. This Act, which evolved from earlier legislation in 1956 and 1968, enforces the following key rules:

• Smoke Control Areas: Prohibits the emission of smoke in designated zones unless using an exempt appliance or authorised fuel.
• Dark Smoke Restrictions: Prevents emissions of thick smoke from chimneys or industrial premises, with certain exceptions.

What is a DEFRA-Approved Stove?

A DEFRA-approved stove is specially designed to meet these stringent requirements, allowing you to burn wood legally in smoke control areas. Failing to comply—such as using unauthorised fuels—can result in penalties of up to £1,000.

In recent years, DEFRA-approved stoves have surged in popularity. For example, they made up 36% of all wood-burning stove sales in 2013/2014, up from 21% the previous year. This growth is largely due to ongoing advancements by manufacturers, such as integrating secondary and tertiary combustion systems. These features reduce emissions and make stoves more environmentally friendly.

What’s the Difference Between DEFRA and Non-DEFRA Stoves?

The differences are minimal but significant. Some non-DEFRA stoves can even be upgraded to DEFRA compliance with a manufacturer-supplied kit. This kit adjusts the stove’s air vents to prevent them from being completely closed. Why does this matter? Some users practice "slumbering"—loading a stove and closing the air vents to burn fuel slowly overnight. While this might seem efficient, it causes soot and tar build up, which can block the flue and increase emissions.

A DEFRA-approved stove is designed to burn cleanly and efficiently at all times, without slumbering. This not only benefits the environment by reducing harmful emissions but also keeps your chimney clear and functional.
