BURNING IN A SMOKE CONTROLLED AREA
If you wish to burn logs in your home and you live in a smoke controlled area, you may only do so if you use an "exempt" appliance; as, under the Clean Air Act 1993, wood is not an authorised fuel.

An "exempt" appliance is one that is suitable for burning unauthorised fuels in smoke control areas, under Regulations published under the Clean Air Act.

At the moment there are only a limited number of appliances that have received exemption, although many of the stoves for sale in the UK would undoubtedly meet the standard required because according to the Solid Fuel Association they use a system of secondary combustion, which means they burn off or 'eat' their own smoke.
