England Social Housing Regulatory Risk Signals

Monitor official regulatory data and return only meaningful changes. This Actor is limited to England and combines the Regulator of Social Housing provider register, published regulatory judgements and enforcement notices, and the current Gradings Under Review list into a persistent provider-level regulatory state.

Signals

• NEW_REGISTERED_PROVIDER and PROVIDER_DEREGISTERED
• CONSUMER_GRADE_CHANGED, GOVERNANCE_GRADE_CHANGED, and VIABILITY_GRADE_CHANGED
• GRADE_DOWNGRADE and GRADE_UPGRADE
• ADDED_TO_GRADINGS_UNDER_REVIEW and REMOVED_FROM_GRADINGS_UNDER_REVIEW
• NEW_REGULATORY_JUDGEMENT
• NEW_ENFORCEMENT_NOTICE

New enforcement notices are critical. Addition to Gradings Under Review and official grade downgrades are high severity. Grade upgrades and removal from review are low-severity informational changes. Other grade and judgement changes are medium severity.

Official England sources

• Registered providers of social housing — XLSX, normally updated around the middle of each month
• Regulatory judgements, enforcement notices and gradings — searchable XLSX, updated when publications are released
• Gradings Under Review — official current England list, updated when providers enter or leave review

The RSH registration number is the stable provider key across sources. Provider names are descriptive only and are never used for entity matching. GOV.UK content is available under the Open Government Licence unless otherwise stated.

Grade handling

The Actor follows the RSH definitions in which C1/G1/V1 are the strongest grades and C4/G4/V4 represent the most serious failings or intervention. It emits upgrade/downgrade signals only when both old and new values are known official grades in the same dimension. Unknown grades are not ranked. Null-to-value and value-to-null transitions are not classified as upgrades, downgrades, or risk events.

Baseline and snapshot safety

The first successful live run validates every source and stores a full baseline without emitting all existing providers as new. Later runs compare a newly merged provider regulatory state with the previous successful snapshot. An identical source state emits zero signals.

The order is fetch, validate, normalize/merge, load the previous snapshot, diff, write Dataset records, write/validate SUMMARY, then commit the full snapshot. Fetch, parsing, schema, source-count, Dataset, or summary failures leave the prior baseline authoritative. Per-source collapse guards compare current counts with prior successful counts. Filters and maxItems affect Dataset output only and never truncate the snapshot.

mode=sample provides a fresh-account demonstration through the same diff engine without external requests or production baseline access.

Input and output

Inputs include mode, maxItems, optional signalTypes, optional registrationNumbers, optional providerQuery, and baselineOnly. Each Dataset record contains one signal, severity, RSH registration number, provider details, grade or publication context, official source, and detection time. SUMMARY reports England scope, source and provider counts, signal counts, and snapshot status.

Limitations

This Actor reports published RSH information for England. Source updates are periodic, not real time. Small providers may not receive grades. A published judgement can cover more than one landlord, while the workbook assigns the publication to its primary RSH registration code. The Actor does not guarantee compliance or risk detection, predict future intervention, replace complete due diligence, or provide legal advice. Compute downloads and normalizes the full official workbooks; persistent key-value storage retains only the latest successful full snapshot.
