The Quarterly Retail Energy Market Monitoring (QREMM) Report for Q4 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.
Highlights from the Q4 2025 report include:
Overall electricity switching activity in Q4 2025 increased from the previous quarter. Domestic customers continue to engage in the market with over 44,500 domestic switches completed during Q4 2025, a switching rate of 5.2% (an increase from 3.0% in Q3 2025). There is an increase in underlying switching rate which is in part due to Electric Ireland’s decision to leave the domestic electricity market. This has occurred for most of their domestic credit customers and is reflected in this QREMM report. However, the I&C sector saw a decrease in electricity switching, with a rate of 2.0% in Q4 2025 (a decrease from 2.3%).
In the gas sector, domestic switching in the Greater Belfast area for Q4 2025 saw the most switches ever completed, for the second consecutive quarter, with c5,813 switches, (a substantial increase from 2,209 in Q3 2025, the previous historic high). I&C switching saw a slight increase in switching activity from 0.9% in Q3 2025 to 1.1% in Q4 2025.
There is no new pricing data in this report however there have been a number of revision to the Gas pricing to reflect more accurate historic information.
In the gas sector, for semester 1 (January –June):
- NI domestic gas prices for NI (9.0 p/kWh) were below Ireland (10.3 p/kWh) and the EU (10.3 p/kWh). This was also higher than the UK (7.0 p/kWh).
