People in Merton with real coal fires or wood burning appliances are being asked not to use them unless there is no other option.

The council says it wants to reduce “dangerous” air pollution in the borough.

Wood burning stoves and coal fires are the second-largest source of the pollutant PM2.5 according to Government figures.

It’s said the tiny particles can increase the risk of stroke, asthma, lung cancer, heart disease and dementia.
