Electricity: UK Trade with EU
The question
To ask the Minister for the Cabinet Office, with reference to the policy paper entitled Outcome of the exploratory discussions on the possible participation of the United Kingdom in the European Union’s internal electricity market, published on 22 December 2025, whether he has made an estimate of the cost of the UK being a member of the EU electricity market.
Answered by Nick Thomas-Symonds
An electricity agreement with the EU will cut the cost of trading electricity with the EU - this means lower wholesale costs and ultimately lower bills. To unlock these benefits, we are prepared to make an appropriate and proportionate financial contribution to support relevant costs, such as accessing specific agencies or databases required for market participation. Nothing has been agreed yet and we will work through the specific details in negotiations to ensure any contribution represents value for money for the UK taxpayer.
