Market-wide Half-hourly
Settlement (MHHS)
Market-wide half-hourly settlement is one of the most significant reforms the UK electricity market has seen in decades.
What is MHHS?
MHHS is an OFGEM-led industry reform. This approach will modernise all electricity meters to settle using actual half-hourly consumption data, not assumptions or averages.
The move to Half-Hourly Settlement replaces estimated data with standardised, granular consumption profiles. This modernisation of the UK energy infrastructure is a critical pillar for the energy grid and a more transparent, competitive retail landscape.
Between September 2025 and July 2027, we are working alongside the wider energy sector to transition all meters to Half-Hourly Settlement in strategic stages.
