Energy Market Investigation (Gas Tariff Codes) Undertakings 2016

These undertakings impose obligations in relation to gas tariff pages on the energy suppliers who have signed them.



These undertakings were made under the market investigation provisions of the Enterprise Act 2002.

The signatories must:

  • hold no more than 12 gas tariff pages each
  • provide information to the Gas and Electricity Markets Authority (GEMA) so it can monitor gas tariff codes allocation
  • follow directions from GEMA to transfer their gas tariff pages to other suppliers

Further information is available on the energy market investigation case page.
