Data Sources
See the data sources and update timing behind DealGrade scores.
Data principles
Show the source
Show where the data came from and when it was checked.
Be clear about limits
Use area data as a guide, not proof about one property.
Coverage transparency
Be clear when coverage is thin or missing.
How we track the data
DealGrade uses official and licensed data, then keeps a record of what each score was based on.
Licensing
We only show source credits and reuse notes where they matter to the result.
Freshness
Every score shows its data date so you can tell how recent it is.
Source allocation guide
Environment Agency flood risk
https://environment.data.gov.uk/5-8% direct DG Score allocation
Flood bands, polygon/postcode matches, lookup status, and match granularity.
Mapped-area signal, not a property-level flood certificate.
Domestic EPC register
https://epc.opendatacommunities.org/4-6% direct DG Score allocation
EPC band, certificate context, and energy-efficiency evidence where matched.
Fallback matches must not be read as confirmed property-level facts.
Police UK crime data
https://data.police.uk/2-4% direct DG Score allocation
Area crime counts, category mix, sample period, and sample-depth context.
Area-level proxy for demand/perception, not a property-level safety assessment.
VOA Local Housing Allowance
https://lha-direct.voa.gov.uk/0% direct DG Score allocation
Support-rent benchmark used for rent-stress and downside-rent context.
Stress benchmark only; not double-counted as a base score contributor.
Postcode and geography normalization
https://geoportal.statistics.gov.uk/0% direct DG Score allocation
Postcode normalization, geocoding, nation/region, and geography metadata.
Supports matching and provenance only; not a risk score by itself.
Registered lease data
https://use-land-property-data.service.gov.uk/Feeds Lease Risk when matched
Lease date, term, match details, and conflict evidence where available.
Only affects leasehold scoring when match confidence is acceptable.
0% direct sources are still shown because they affect confidence, provenance, stress context, or source matching.
