Market-Wide Half-Hourly Settlement (MHHS) is a major regulatory change set to transform the way businesses are billed for electricity. Traditionally, many businesses, especially smaller ones, have been billed using estimated or profile-based data. With MHHS, all meters will settle based on actual half-hourly usage data.
What is MHHS?
MHHS ensures that energy usage is recorded and charged in 30-minute intervals. It provides a much more accurate representation of when and how energy is consumed, replacing the older profiling methods.
Why It Matters
- Enables more accurate billing
- Encourages smarter energy usage
- during off-peak periods
- Opens up better tariff options based on your real consumption patterns
- Supports the UK’s net zero goals by improving demand-side response
Who Will It Affect?
MHHS will eventually apply to all non-domestic electricity users. Smart meters are essential for this change, if your business doesn’t yet have one, it will need one installed to comply.
Timeline
The transition to MHHS will happen gradually, with full market implementation expected by the end of 2026. However, suppliers and brokers are already preparing for the change.
How to Prepare
- Ensure your smart meter is installed and functioning correctly
- Begin analysing half-hourly data now to spot usage trends
- Talk to your broker about tariff options that reward time-of-use efficiency
Takeaway
The businesses that benefit most from MHHS will be those who prepare early and use data to their advantage. Utiliplus can help you get ready, analyse your data, and find cost-effective contracts based on your actual usage.
