Measurement Class
MeteringA single-letter code (A to G) that classifies how a meter is measured and settled, sitting alongside the Profile Class. Under MHHS, meters are also organised into three settlement segments: Smart, Advanced, and Unmetered.
Measurement Class is a letter (A to G) that tells the industry how a supply is metered and settled. It sits alongside the Profile Class in settlement data.
The classes (A to G):
| Class | Meaning |
|---|---|
| A | Non-half-hourly metered |
| B | Non-half-hourly unmetered supplies |
| C | Half-hourly metered, 100 kW and above |
| D | Half-hourly unmetered supplies |
| E | Half-hourly, under 100 kW, CT metered |
| F | Half-hourly, under 100 kW, domestic (smart / MHHS) |
| G | Half-hourly, under 100 kW, non-domestic whole-current (smart / MHHS) |
What MHHS changes: MHHS does not abolish the Measurement Class field, but it organises meters into three settlement segments for data services, cutting across the old half-hourly versus non-half-hourly split:
| MHHS segment | Covers |
|---|---|
| Smart | Smart and traditional meters at consumer and small-business level |
| Advanced | AMR and CT-metered supplies, typically larger or more complex sites |
| Unmetered | Street lighting, traffic signals and similar |
A note on terminology: These MHHS settlement segments are different from the import or export market segment (Domestic, Non-Domestic, Generation, Unmetered) that the LLFC encodes for charging. One describes how a meter is settled; the other describes what kind of supply it is for charging purposes.
