1. Summary of a MAP portfolio
To assess the extent to which map portfolio data matches existing data on S&M. Calvin Asset Management provided their “supplierless” portfolio.
Calvin provided MPRN, MSN, meter model
Xoserve assessed this against the S&M records

2. “Supplierless” results…
There were MPRNs with a live confirmation
12029 of have a MSN exact match, although more matched when leading zeros removed.
No evidence of “made up” serial number
165 of have no meter asset attached (of these 128 show as a meter removal (17 exact match on MSN, remainder were not an exact match – this may suggest a new meter has been installed but Shippers have not updated the records) and 37 show as no asset ever attached – suggesting an asset update is on its way)

3. …. “Supplierless” results
18896 of have meter capacity below 11 cubic metres
881 records were isolated and withdrawn (did not have a live confirmation).

4. Conclusions
Having reviewed the data Xoserve considers there is a high match to MSN and therefore the exercise has demonstrated a positive case and that the output is of value both to the MAP and Supplier organisations
