If you want to put a skip on a public road you need to apply for a skip permit/licence. You can't put a skip on the pavement. You don't need a licence if you're putting the skip entirely on private land.

You also need a licence for skip bags and hippobags.
You may need to put safety lights and markings on or around the skip, and you could be fined up to £1,000 if you fail to do this.
