Heralded as the biggest shake-up since privatisation, Market-wide Half-Hourly Settlement (MHHS) will impact every school and MAT.

The programme is now underway, marking a major step forward in how the UK’s electricity is measured and billed.

MHHS will see every electricity meter read and settled every 30 minutes, replacing estimated billing for non-half-hourly meters. This change will bring greater accuracy, transparency and efficiency across the energy market, helping the grid to balance electricity demand and support renewable integration and decarbonisation.

Find out what this major industry change means for your school or MAT in Zenergi’s webinar on 22 October. Discover the potential challenges migration might bring and how you can mitigate them, as well as how you can benefit from what’s to come.
