Most waste disposal firms are legal and licensed by Natural Resources Wales or the Environment agency!
Just having a Waste Carriers Licence doesn't mean they're disposing of your rubbish legally.
You need a waste transfer invoice when your rubbish is collected.
All waste that you pay to get rid of should be taken to a commercial waste transfer station for disposal, and were possible recycled!
Paperwork should be provided and contain all details as follows:
Carriers Name and Address
Disposal site licence number
If you are not given these details you are not dealing with a legitimate waste removal firm!
If you're offered cheap waste disposal without the proper paperwork then they are not a legal company.
You may be adding to the massive fly tipping problem the UK face's.
