Every firm here is real. We took each name, town, website and phone number from the firm's own website (or, for one firm whose site shows no phone number, its trade-directory profile), then looked the business up on the Environment Agency public register of waste carriers. We only list firms with an upper-tier registration that was current on the date we checked. Nobody paid to be listed. We have not used them and we are not recommending one over another.
Check a carrier before they empty your tank
Under the general binding rules, the firm that takes your sludge away must be a registered waste carrier. Ask for their carrier number, or ask the tanker driver to show the certificate. Then search the number or name on the EA register. Registration numbers starting CBDU are upper tier, the tier normally needed to carry other people's waste as a business. Keep your emptying receipts: buyers' solicitors ask for them.
