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 and ownership), check the property (EPC and MEES, flood, crime), and keep one signed certificate for the file. Start a letting transaction and run only the checks that let needs.
A let from £1.98 (the tenant and the landlord). Free demo, no card.
For estate agents and conveyancers
Handle a sale
Screen buyer and seller for sanctions, PEP and adverse media, check any company and its owners, and add the property risk pack, in one transaction with one signed certificate that sits alongside your regulated, insured searches (not in place of them).
A sale from £2.78 (the buyer and the seller, with PEP and adverse media).
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 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.
