I'm sure it does cover you for three years, I've looked into it in some depth a while back, coz i will need one too, before next year, by law anyway. i think getting it soon would be a good idea, coz I think there will be a big rush come the deadline. Havent looked into registering as a broker much. Seems to me that being a carrier, it doesn't mean much, coz loads of people are doing that, but going as a broker could attract more attention from the EA, coz your really saying that you are dealing in waste as a business, rather than with waste as part of your business.
