In delivering against these commitments, the Infracos must meet a variety of standards, covering such areas as:

■ safety;

■ environment; and

■ interfaces and interoperability.

Appendix 2 provides an illustration of how these standards fit into the overall incentive regime that LUL monitors Infraco progress against.
