Defra Approved Appliances, there is no such thing as a defra approved stove, Defra exempt is the correct terminology and these stoves are cleared and tested to burn only specified fuels in specific Smoke controlled Areas.
Fuels that are disallowed in smoke controlled areas include wood unless the stove is a defra exempt stove, so you can fit a non-defra exempt stove in a smoke controlled area if you are going to burn any authorized smokeless fuel
Another advantage of defra exempt stoves is that they can be legally attached to a 125mm (5'') liner if a liner is required and wood can be used, Only if the manufacturer allows this in the fitting instructions, In all other circumstances and to comply with building regulations a 150mm (6'') liner must be used

DEFRA is the UK Government Department of the Environment, Food and Rural Affairs which regulates smoke emissions under the Clean Air Act 1993.
Defra approval is an advanced system of eco-engineering approved by the UK Government for burning wood in smoke control areas, and is among the most safe and friendly heating solutions in the world.
Wood is one of the few natural renewable and sustainable energy sources available, and when used with a correctly installed approved smoke controlled stove, gives many economic and environmental advantages.
