All councils in London subscribe to an air pollution warning system.

Anyone can ask to subscribe to receive texts or emails warning them about imminent bad air pollution events that if they or a family member have a pre existing medical condition can change their plans to minimise any risk – such as avoid strenuous exercise.

To register either text AIRTEXT to 78070 or visit the www.airtext.info website.

It is a sad reflection on our society that this is necessary but insufficient political will by the Mayor of London means this service can be a life saver for some.
