APIs/UK Postcode Intelligence

UK Postcode Intelligence

Crime, flood, schools, deprivation, EPC and property prices for any UK postcode in one API call.

What it does

One endpoint enrichment for any UK postcode. Combines crime rates from Police.uk, flood risk from the Environment Agency, IMD deprivation deciles from ONS, school quality from Ofsted/DfE, EPC band averages from MHCLG, and recent sale prices from Land Registry Price Paid Data. Built for estate agents, relocation services, insurance underwriters, and property investor dashboards that need a single normalised JSON shape rather than six separate integrations.

Built for

  • Estate agents and property portals
  • Relocation services and HR/employer mobility tools
  • Insurance underwriters needing peril overlays
  • Property investor dashboards and BTL sourcing tools
  • Mortgage lenders doing area-risk overlays

Data sources

How we compare

ProviderEntry priceWhere they fall short
PropertyData~£49/monthProperty-centric; weak on non-property layers like crime and schools
GetAddress.io~£10/monthAddress validation only; no enrichment

Reliability you can build on

Built on the same AWS infrastructure that runs UK banks and government services. Engineered for the kind of always-on availability your compliance workflow expects.

Target 99.9% uptime

Stack uptime is governed by AWS API Gateway (99.95%), Lambda (99.95%) and DynamoDB (99.99%) SLAs. We target 99.9% end-to-end, which works out at roughly 8 hours of downtime per year, worst case.

Hosted in London (eu-west-2)

Single-region UK hosting for low latency to UK customers and predictable data residency. Median response under 250ms; 5-minute response cache absorbs upstream blips.

Idempotent + cached

Repeat lookups within 5 minutes are served from cache, so transient FCA upstream issues don't propagate to you. Bulk endpoint runs with bounded concurrency to never overrun the source.

Contractual SLA on Pro

Pro plan includes a 99.9% uptime commitment, priority support with response in under 4 hours (UK business hours), and a private Slack channel for incident escalation.

Live status visibility lands with the public dashboard. Full incident history available to Pro customers on request.

Why this pricing?

The cheapest single-feature alternative for flood risk is Landmark's per-report service at £8 to £15 per check. Even at four checks a month that exceeds our £29 minimum, so a customer who needs flood data plus any one other layer breaks even immediately. Address-only validation APIs (GetAddress.io, Postcoder) charge £10 to £30 a month with no enrichment, so we sit one tier up reflecting the ten-plus layers combined. Free Police.uk integration alone would cost a developer more in maintained-integration time than £29 a month.

Missing something?

Need a field we don't return, a regulator we don't cover, or a workflow our pricing tiers don't fit? Tell us. We're small enough to ship custom changes quickly: sometimes free, sometimes for a one-off fee, always with a fast yes/no on whether we can do it.
