Like or not they do. Another member related such a story,
@SparkyChick, I think it was. Then there was that incident recently where environmental agency gave a builder a fpn for carrying sandwich wrappers in a waste bag in his van!!
I got myself a lower tier waste licence (free), which allows me to carry waste generated by myself, but soon as you start collecting scrap cable etc to take to the scrappy, its the upper tier (£229 +VAT). The definition, is it someone else's waste, you need a licence.
Not stopped me from being naughty boy, but something you might wish to be aware of.
