Smoke Control Areas

A Smoke Control Area (SCA) is a legally defined area where you cannot emit a substantial amount of smoke from a chimney.

Boats line a tree-covered canal with smoke coming out of the chimneys.

You can be issued a financial penalty of up to £300 if you break this rule. Only local authorities have the power to enforce SCAs and issue fines (the Canal & River Trust does not issue fines or manage SCAs).

Smoke control orders can be applied to boats following the passing of the Environment Act 2021, but local authorities must consult before they extend their SCA to include boats. SCA rules do not cover generators or boat engines.

Where an SCA covers a canal or river, and the local authority wishes to extend the SCA to cover boats, we are requesting that they pay for signage to make clear to boaters where they are entering an SCA.

The first SCAs covering boats on Trust waterways came into effect in 2024. Others have since been added, or are undergoing consultation. For more details and to see the Smoke Control Order for each one, please visit the local authority websites listed below. While we aim to keep this list up to date, we cannot guarantee that it is complete so please look out for local signage or contact your local council for details.

Don’t burn rubbish!

A minority of boaters still burn rubbish and wet or treated woods. Not only is it bad for their health, but it affects others too, so please spread the word or point them in the direction of this handy guide by Burnright.
