Unified data API
Clean, versioned responses for company, property, planning and regulated public records with provenance attached to every result.
Coming soon — UK-first developer preview
Government data workflows, without government integration pain.
GovLayer is a pre-release API platform for teams building with UK public-sector data. Normalise official records, monitor changes, trigger webhooks and export source-linked evidence packs from one clean developer layer.
- Normalised APIs
- Watchlists
- Webhooks
- Evidence packs
Independent platform. GovLayer is not an official government service and does not imply endorsement. It is designed to help teams use permitted public and official data with attribution, provenance and auditability.
The platform
From scattered public records to product-ready infrastructure.
Every team integrating government-linked data has to solve the same boring problems: source credentials, inconsistent schemas, rate limits, retries, caching, stale records, legal attribution, evidence exports and monitoring. GovLayer turns those repeated integration chores into reusable infrastructure.

FAQ
Questions early customers are likely to ask.
Is GovLayer live?
GovLayer is in pre-release. The landing page is designed to validate demand, collect early access requests and prioritise the first connector roadmap.
Is this an official government product?
No. GovLayer is an independent software platform. It will use permitted public, official or customer-authorised data sources and will not claim government endorsement.
What makes this more valuable than direct API access?
Direct API access still leaves teams with schema mapping, rate limits, caching, change detection, webhooks, source attribution, monitoring, documentation and evidence exports. GovLayer packages those repeated jobs into one reusable platform.
Will GovLayer support AI agents?
Yes, but safely. Early AI support should focus on retrieval, summaries, evidence packs and suggested next actions. Official submissions or sensitive workflows need human approval, consent and audit trails.
How will data protection be handled?
The platform should minimise stored personal or sensitive data, attach provenance to every result, support retention rules, avoid raw sensitive identifiers in logs and use stricter controls for vehicle, tax, sanctions and regulated workflows.
