Welwyn Hatfield borough is not a smoke control area and there are no by-laws regarding the times that residents may have bonfires.
Bonfires are not an acceptable method of disposing of domestic garden rubbish or commercial trade waste.
They cause extreme nuisance and are the subject of many complaints to Environmental Health. For trade waste there are very strict penalties for adversely impacting on the environment or human health.
