Certaby

How it works

How Certaby works.

One place to handle the compliance for a let or a sale, monitor the parties over time, and keep the written records an HMRC inspection asks for. Here is what that looks like for each job. Every check and tier is pay-as-you-go with a signed certificate and a 7-year verify URL; the full catalogue is below.

For letting agents

Handle a let

Screen the tenant and landlord (sanctions, PEP, adverse media and ownership), check the property (EPC and MEES, flood, contaminated land), and keep one signed certificate for the file. Start a letting transaction and run only the checks that let needs.

Pay per check, from 49p. Run only the checks a let needs. Free demo, no card.

For conveyancers

Handle a sale

Pre-screen buyer and seller for AML, walk corporate ownership, and triage the property’s environmental risk, in one matter-referenced pack that sits alongside your regulated, insured searches (not in place of them).

Pay per check, from 49p. Run only the checks a sale needs.

An ongoing duty, not a one-off

Monitor the parties for changes

MLR-2017 asks for ongoing monitoring, not a single check at onboarding. Keep a watch-list re-screened daily for new sanctions, PEP and adverse-media matches, with an alert the moment something changes.

Monitoring from £19.99 a month.

When HMRC asks

Stay inspection-ready

The written evidence an HMRC inspection asks for: your AML risk assessment, policies and controls, nominated-officer record, training log, case management, and a single inspection bundle, built from your firm profile and your transactions.

Part of the Compliance plan.
