The rollout of Market-Wide Half-Hourly Settlement (MHHS) has been delayed until October 2025, giving businesses more time to prepare for this important change. MHHS is set to transform how energy is billed and managed by using specific data from smart meters to encourage smarter energy use and better efficiency.
This delay gives businesses a valuable opportunity to plan ahead, review their energy management strategies, and take steps to prepare for the new system.
What Is MHHS?
MHHS is an Ofgem-led program designed to improve how energy consumption is tracked and billed in the UK. Unlike the current system, which uses larger time intervals to calculate energy use, MHHS will measure energy consumption in 30-minute intervals.
By using smart meters, the system will enable more accurate billing and provide insights into how and when energy is being used. This will allow businesses to make informed decisions, such as shifting usage to off-peak times to reduce costs. It also supports the broader move toward sustainable energy practices by encouraging flexibility in energy consumption.
Why Has The MHHS Deadline Changed?
The new deadline of October 2025 reflects the scale of the transformation MHHS requires. Implementing a market-wide change like this comes with significant technical and operational challenges.
Industry feedback highlighted concerns about meeting the original timeline, and Ofgem has responded by revising milestones to allow more time for preparation. While the delay may be disappointing for some, it ensures a smoother transition and gives businesses additional breathing room to get ready.
