Smoke Control Areas and the Clean Air Act 1993
The Clean Air Act of 1993 allows local authorities to declare certain districts, or certain parts of a district, as a Smoke Control Area. This act states that emitting smoke from the chimney of any building or from a furnace or fixed boiler in a Smoke Control Area is considered an offence. Another offence is the acquisition and use of unauthorised fuel, unless it is used in a DEFRA Approved, or Smoke Exempt appliance, which is exempt from from the general applications within a Smoke Control Area. These appliances are required to undergo intense scrutinisation during the authorisation process, and should always be operated according to the specifications and instructions of the manufacturer.
Some of the largest designated Smoke Control Areas include all of Belfast, London, and Manchester. Some smaller, yet still significant Smoke Control Areas include The Midlands, North West, North East, and South Yorkshire in England, as well as the Central and Southern regions of Scotland. In these areas you are only allowed to burn authorised, smokeless fuels, as wood fuel is only allowed to be burnt in a DEFRA Approved stove. However, if you burn wet or unseasoned wood, which may cause excessive smoke, in a DEFRA Approved wood burning stove you will still be using the stove in an unlawful fashion.
