You'll need a licence to run a business as a scrap metal dealer. Trading without a licence is a criminal offence.
There are two types of licence you can apply for:
Site licence
All sites where you are running a business as a scrap metal dealer must be licensed and a site manager will need to be named for each site. This licence will allow you to transport scrap metal to and from those sites from any local council area.
Collectors licence
A collector's licence will allow you to operate as a collector in the area of the issuing local council. It doesn't allow you to operate in any other local council area and you'll need a separate licence from each area you want to collect in.
A collector's licence doesn't authorise you to operate a site, you'll need a site licence for this.
Please be aware that a dealer can only hold one type of licence in any one local council area. You will need to decide whether you are going to have a site or a collector's licence in any one area
