The Utility Regulator has published the Quarterly Retail Energy Market Monitoring report for the first quarter of 2026. The report is part of a series providing information on Northern Ireland’s retail energy market.

The document contains data collected from electricity and gas network companies and suppliers under the Retail Energy Market Monitoring framework. Indicators covered include market behaviours and regulatory compliance.

The regulator said the information is used to review the progress and impact of supply competition. It also helps build knowledge for future regulatory decisions and allows stakeholders to understand activity within the energy markets.

The publication aims to promote the interests of consumers by enhancing transparency. Copies are available in accessible formats on request.
