Licences, codes and standards

Under the Gas Act 1986 and the Electricity Act 1989 certain activities concerning gas and electricity may only be carried out with a licence (or under a relevant exemption or exception).

One of our responsibilities at Ofgem is to determine the content of gas and electricity licences, and to grant licences to successful applicants. We assess applications for licences in accordance with our published criteria.

There are certain conditions that licence holders must comply with, including conditions in relation to a number of industry codes and standards. The codes and standards establish rules that govern market operation and the terms for connection and access to energy networks.
