GeoSure Insurance Product V7 2016.1

This dataset is the Derived Postcode Database issued as part of the GeoSure Insurance V7 incorporating postcode data from OS Code-Point Open version 2016.1. The GeoSure Insurance Product (including the Derived Postcode Database) represents the end of an interpretation process, starting with the BGS Digital Geological Map of Great Britain at the 1:50,000 scale (DiGMapGB-50). This digital map is the definitive record of the types of rocks underlying Great Britain (excluding the Isle of Man), as re

Coverage docs-verified: Great Britain · 2016-11 dataset reference date (OS Code-Point Open 2016.1 postcodes)
Resolution docs-verified: Postcode-level database; underlying source mapping at 1:50,000 scale (DiGMapGB-50)
Update frequency docs-verified: As needed (metadata 'asNeeded'); last updated 2 October 2026

Useful for

Use cases llm-inferred: Subsidence and ground-stability screening of low-rise residential sites by postcode during desk studies · Shrink-swell clay and running sand hazard context for foundation and geotechnical desk assessments · Lender or insurer property ground-risk screening for portfolio or mortgage due diligence · Postcode-level hazard context in planning or site-selection reports
Audience llm-inferred: geotechnical engineers · civils engineers · GIS analysts · planners · insurance and lending risk analysts

Limitations

Constraints docs-verified: Scored for low-rise buildings only, not larger structures · Hazard scores come from expert analysis and statistical balancing, not site investigation · No warranty of quality, accuracy or suitability; use is at the customer's own risk · Restrictive copyright; reproduction needs permission · Postcode-level screening only; not a substitute for site-specific ground investigation
