What is MHHS?

This section has a short video explaining MHHS, key timelines and updates as and when they happen!

 

Important Note: 

Meter Migration: 

1st May 2026 : The first big meter migration begins. We expect about 250,000 to 500,000 meters to be migrated  across the following suppliers:

  1. Yu Energy

  2. EDF Energy

  3. E.On Next 

  4. Drax Energy

Quoting for Migrated Meters in Broker 360:

All suppliers are now quoting on the Broker 360 software. The exceptions are:

E.On Next and Smartest Energy: They should be quoting in the next 2 weeks

Utilita and Corona Energy: There is no planned dates for when they will start quoting

kVA / Capacity Charges Post-MHHS

After MHHS rollout, measurement class should no longer be used to determine whether kVA / DUoS capacity charges apply.

For legacy HH meters, this field may still appear temporarily, but it is not a reliable indicator.

Going forward, capacity charges are based on:

  • Actual demand, and
  • DNO-authorised capacity and not settlement classification.
