Managing your metering estate with Data Health
MHHS migration is underway.
By October 2026, millions of commercial and domestic meters will deappoint, reconfigure, or be replaced as the UK transitions to Half Hourly Settlement.
For energy managers, this represents significant disruption. The more complex your metering estate, the more essential it becomes to understand the condition of your meters today.
If you already have data gaps now, how will you manage when MHHS activity accelerates?
The MHHS metering challenge
Market-wide Half Hourly Settlement will fundamentally change how meters operate and how frequently they must report data.
Even meters currently operating well may experience temporary data interruptions as industry agents process deappointments and reappointments into new MHHS flows.
This creates immediate risks:
- Loss of data access – Deappointments interrupt data flow until the meter is reappointed again
- More gaps and faults – Not all metering agents will cope when every meter reports Half Hourly data. This is where agents who can dial all meters remotely become crucial
- Disrupted Net Zero tracking – Missing data means you can’t measure consumption accurately
- Estimated bills – Gaps in data often result in estimated invoices and uncertainty
The businesses that navigate MHHS successfully will be those who prepare now. And preparation starts with understanding your metering estate today.
Why traditional meter management struggles during MHHS
Managing a metering estate is complex.
You’re dealing with multiple suppliers, Data Agents, Metering Agents, and different collection technologies across multiple utilities.
Half Hourly data is the new standard, and every 30-minute gap matters. You need immediate alerts about meter issues, clear responsibility and actionable next steps.
This is where Stark ID Data Health transforms meter management.
"It allows us to pick up and investigate problems before clients spot an issue. Being ahead of the issue means happier clients. Being able to notice and resolve missing data gaps and de-appointments means that we can avoid bigger or more time-consuming issues down the line."

How Data Health supports in preparing for MHHS
Data Health doesn’t track MHHS migrations or agent-side programme activity.
What it does do is give you a clear, accurate and timely view of your meter data performance. So you can stay ahead of issues during a busy industry transition.
Data Health updates every two hours and provides:
Instant visibility of your entire metering estate
The Data Health dashboard shows:
- The percentage of data sources currently up to date
- Breakdown by utility, settlement class, or collection type
- Issues needing your attention vs those handled by Stark or your Metering Agent
Any data source without data in the last 7 days is flagged, and estimated data is intentionally excluded to help you focus on real problems.
Meter-by-meter insights that drive action
The Meter Health section shows specific issues.
Select any data source and see:
- Data sources not up to date by fault type
- Top 5 actions needing attention by volume
- Detailed table with all data sources prioritised by urgency
Each meter includes clear information about the fault and who owns the next step, helping you resolve issues faster.
Filter and focus where it matters
Managing multiple sites and meters? Filtering helps you prioritise.
Filter by:
- Metering Agent or Stark – Review specific agent performance
- Utility – Focus on electricity, gas, or water separately
- Site – Drill down to troublesome locations
- Fault type – Identify patterns across your estate
This makes it easier to identify patterns and uncover persistent weak points.
Clear responsibility for every issue
Data Health categorises every issue by responsibility:
- You – Actions your team needs to take
- Metering Agent – Issues the Metering Agent must resolve
- Stark – Actions we’re handling
This transparency helps you prioritise time and hold stakeholders accountable.
The cost of not preparing your metering estate
MHHS affects every commercial electricity meter, and readiness starts with reliable data.
Without good meter health, you risk:
- Financial cost – Overpayments and billing disputes
- Time cost – Managing data gaps during peak MHHS activity
- Net Zero cost – Inability to track energy performance accurately
- Opportunity cost – Missing out on new tariff models and load‑shifting incentives
A healthy metering estate now puts your organisation in the best position to benefit from MHHS outcomes later.
Data Health is essential for MHHS readiness
MHHS will require accurate, consistent Half Hourly data across the entire market.
Data Health helps you prepare by giving you:
- Full transparency over your data flows
- Early detection of faults and deterioration
- Clear ownership of next steps
- Estate‑wide visibility before industry activity increases
Use Data Health today to strengthen your meter readiness for MHHS.
