Preparing for MHHS implementation
The Market-wide Half Hourly Settlement (MHHS) reform is set to transform the energy sector, delivering significant benefits to customers through greater efficiency, more accurate billing, and enhanced service offerings. As the industry prepares for this shift, organisations must manage a range of challenges, including updating systems and processes, engaging effectively with customers, and addressing workforce training and upskilling needs.
At BFY, our team offers deep expertise in delivering complex industry transformations, helping clients tackle these challenges through strategic planning, operational improvements, and risk mitigation. Our insights explore key questions such as:
- What are the key risks organisations must consider when implementing MHHS?
- What practical steps can suppliers take to ensure a smooth MHHS transition and maximise customer benefits?
- Who will emerge as the winners and losers in the industry once MHHS goes live?

Market-wide Half Hourly Settlement
Creating a winning business readiness plan for MHHS
Ofgem’s deadline for Market-wide Half Hourly Settlement (MHHS) implementation is expected to be pushed back again, from December 2026 to May 2027. Given this is the most fundamental change to the electricity market since privatisation, the revised implementation timeline provides suppliers with a new opportunity to nail their readiness plan.
Dynamic tariffs saved £150 on electricity for typical customers in last 12 months
‘Typical’ customers would have saved £150 in the last 12 months on a dynamic time-of-use electricity tariff – but will need to be able to shift their consumption to achieve the same in 2025.
Getting operationally ready for change in a dynamic energy market
Avoiding expensive delays is key in any change programme, and the risks are getting greater with smart targets and MHHS on the horizon. Often, suppliers have the right idea on what to change, but fall short in realising benefits due to how the change is delivered. Here, we show why operational readiness is key to nailing this delivery, with five focus areas to sharpen your approach.
MHHS could pose a major commercial risk for suppliers
Market-wide Half Hourly Settlement (MHHS) has the potential to pose a major commercial risk for suppliers, with a risk of overpaying for energy purchases by up to 8%.
Improving settlement performance is a ~£200m opportunity for suppliers
Since the migration of first-generation (SMETS1) smart meters into the DCC network, there’s been a steep decline in settlements accuracy across the energy industry, which could be costing suppliers up to £200m based on our analysis.
Identifying opportunities for smart rollout acceleration
The government's smart rollout target for 2025 is getting closer, and although our analysis shows most suppliers are set to fall short of 75% coverage, opportunities to hit the target still exist - as shown in this article.
