The UK energy market is undergoing one of its most significant transformations in decades — and at the heart of this change is Market-Wide Half-Hourly Settlement (MHHS).

But what is MHHS, and why should your business care?

⚡ What is MHHS?

Market-Wide Half-Hourly Settlement (MHHS) is a programme led by Ofgem to modernise the way electricity consumption is recorded and billed across Great Britain. It will require all electricity usage to be settled based on half-hourly data, using smart meter readings.

Previously, only large businesses or those with specific meters were settled this way — now, MHHS will apply to all customers, including SMEs and microbusinesses.

🧠 Why Is It Being Introduced?

The aim is to create a faster, smarter, and more flexible energy market that reflects real-time electricity usage. This supports the transition to a low-carbon grid and encourages energy efficiency.

MHHS will:

• Enable more accurate billing based on actual usage
• Encourage off-peak energy use through dynamic pricing
• Help integrate renewable energy and electric vehicles (EVs)
• Improve competition among suppliers, benefitting consumers

🏢 What Does MHHS Mean for Businesses?

For your business, MHHS means:

• Greater control over your energy costs
• Opportunities to shift consumption and save during off-peak hours
• The need for a fully functioning smart meter to provide half-hourly data
• Potential for more tailored energy contracts based on real usage patterns
