Hi there We have had a white van come and go on our road circling neighbourhood lookng for scrap things. I saw a man coming up our drive when I opened the door he was bit surprised, i asked him what he wanted, he said did we have any scrap metal, I said no but he asked If he could take some things from our skip, old cabling and discarded materials. Which I was ok with. I have seen quite a few people scavaging for things recently, if we want anything removed we just put it in our drive. It is the sign of the times, people looking out for things, always see vans stopping at skips and bins in last few months in HOP. May explain your stuff going.
