While we try to answer each call immediately, you may need to leave a voice message if we are busy taking other calls. If you do leave a message we will call you back as soon as possible.

Determinations: A determination is a binding decision by us, including our reasons, in relation to a dispute referred to us under the Acts or the relevant licence provisions.

The circumstances in which a dispute between a licensed energy network company and a customer may be referred to the Gas and Electricity Markets Authority ('the Authority') for determination are set out in: Ofgem guidance on determination of disputes [pdf].

Individual determinations are published on our Electronic Public Register.

Customers or network companies who wish to refer a dispute to us for determination should address their dispute to the Distribution Policy team, Smarter Grids and Governance, Ofgem, 9 Millbank, London SW1P 3GE or send an email to the following address:
