Aggregates Levy Guidance

Operational assurance overview: Accounting database and online registration system

The main accounting database for registered AGL businesses is the NET system, accessed through Open Road application. There is also an Agg Levy Online registration system (intranet-based) which lists, among other things, site details for each registration. You should ensure that site details for businesses you assure are up-to-date and recorded on this system.

Applications for access to both systems should be made through the normal channels for IT requests.

Both systems are maintained by Central Collection Unit (CCU) in Southend. You can contact them on 01702 366558 for further advice.
