Certaby

For UK letting agents · 2026 update

Every check a let needs, on one record.

Handle a let end to end. Open a transaction, screen tenant and landlord (sanctions, PEPs, UBO (ultimate beneficial owner, the real person who owns or controls a company) walk), and check the property (flood, radon, coal, contaminated land, knotweed, MEES (minimum energy-efficiency standard) verdict and payback, crime forecast, A-F neighbourhood index) on the same record. Keep one signed PDF for the file, monitor the parties for changes, and stay ready for an HMRC inspection. Built for the May 2025 sanctions rule, with 2026 list versions stamped on every certificate.

Why does my letting firm need this in 2026?

Because the May 2025 sanctions regulation removed the previous rent threshold; HMRC issued 170 AML penalties in 2025-26 totalling over £835,000; and most letting agents found out late. One signed PDF closes the audit-trail gap.

Honest scope of cover

What we screen and what we don't

Both Standard and Pro screen against OFSI, UN, EU consolidated sanctions plus the OpenSanctions PEP and adverse-media catalogues. Not a substitute for full enhanced due diligence. Under MLR-2017 the regulated party retains responsibility.
