The Quarterly Retail Energy Market Monitoring (QREMM) Report for Q3 2025 is the latest in a series of Utility Regulator reports that provide a range of information about the retail energy market in Northern Ireland.
The QREMM report presents data that we collect as part of the Retail Energy Market Monitoring (REMM) framework. REMM requires network companies and suppliers to submit data on a range of indicators to enhance our transparency around market behaviours and regulatory compliance.
We use the information outlined in the report to review the progress and impact of supply competition; build knowledge for regulatory decisions; allow other interested stakeholders to understand more readily the activity within our energy markets; and to help promote the interests of consumers.
