Our local tip now charges for diy waste even though government advice states that diy (not trade) waste should be free
Do you have a link / reference for that?
My council changed their policy in autumn 2014 so that householders have to pay the same rates as traders for concrete, brick, rubble, DIY waste, and so on. Roughly 17p/kilo but in bands; 1-120kg = £21, 121-160kg=£26, etc.
The staff said that there was no change, just that it was being enforced now. However there used to be a large metal container for rubble, etc and that had disappeared. I am certain about this as I had noted the large metal container when I was there in the summer of that year.
In the summer I had just come across the concrete footings of a wall and planned to get rid of those footings in that container. But some sort of building must have not just stood there but been demolished in situ. By the time I had dug the footings out and dug over / sieved the area they encompassed I had c. a cubic yard of concrete rubble and a cubic yard of broken bricks and several months had gone by.
