You can't beat a load of damp grass and an old tyre on the fire.
We had someone burning an old shed last week. Is it even allowed as London is smoke free?
Did you know this is illegal? Call the council and get it stopped.
Same here on Wightman today. All the washing has had to come in and all the doors and windows shut. Crap to be forced out of the garden on such a nice day.
According to the link above - "The burning of waste which emits smoke that causes a nuisance is illegal and is an offence under the Clean Air Act 1993 and action can also be taken under the Environmental Protection Act 1990" - from what you say V&M it certainly appears to be a nuisance (that which causes offence, annoyance, trouble or injury)
The problem is if people don't report this, the same people will continue to do it and get away with it. We all really owe it to the wider community to report it.
I'm assuming it's the same as noise complaints though - if there's no address to pin it on they're not very interested?
