Under the Clean Air Act local authorities may declare the whole or part of the
disrict of the authority to be a smoke control area. It is an offence to emit smoke
from a chimney of a building, from a furnace or from any fixed boiler if located in
a designated smoke control area. It is also an offence to aquire an “unauthorised
fuel” for use within a smoke control area unless it is used in an “exempt”
appliance (“exempted” from the controls which generally apply in a smoke control
area).
In England appliances are exempted by publication on a list by the Secretary of
State in accordance with the changes made to section 20 and 21 of the Clean Air
Act 1993 by section 15 of the Deregulation Act 2015. Similarly in Scotland
appliances are exempted by publication on a list by Scottish ministers under
section 50 of the Regulatory Reform (Scotland) Act 2014.
In Wales and Northern Ireland these are authorised by regulations made by Welsh
Ministers and the Department of the Environment respectively.
