Your comments are a reflection of life in Tower Hamlets, where PanP etc. are. London otherwise in the N, NE and SW parts has clean air with plenty of green spaces for kids.
I was not in Tower Hamlets but in the City of London and Southwark, but I'm sure your comment is valid: London is a large area and you can get a better quality of life on the outskirts.
Still, flying from London to somewhere else or taking a train to go outside, the difference in air quality before and after was noticeable.
