People in Richmond with real coal fires or wood burning appliances in their homes are being asked not to use them.

The council says even the most modern, eco-designed ones are a significant source of the pollutant PM2.5.

These are tiny particles that once inhaled can increase the risk of serious health conditions like stroke, asthma and lung cancer.

Richmond is a Smoke Control Area and you can be fined if you break the rules surrounding certain appliances.
