Letting agent suite for high-volume agencies

The problem

A high-volume agency stitches together SmartSearch, OFSI, and Companies House manually. Five tools per applicant; 30 minutes of analyst time per check; no single audit-grade record at the end. The May 2025 LSAG-2025 rule changed UBO requirements; that broke a lot of those manual workflows.

How Stratum fits

The Letting Agent Suite is one POST /v1/suites/letting-agent/check call per applicant. It returns entity verification + UBO walk (depth 5) + sanctions + PEP + adverse media, plus a SHA-256-hash-bound PDF cert valid for 7 years (MLR-2017 retention). At 200+ checks/month the per-call price drops to £4.95 — half the cost of stitching it manually plus zero analyst overhead.
