OFSI: Your Compliance Safety Net, Running 24/7
Sanctions compliance isn't optional for letting agents — and agentOS makes it effortless.
What is OFSI and why does it matter?
OFSI is the UK government body that enforces financial sanctions. There's a consolidated list of individuals that UK businesses are legally prohibited from dealing with financially. Receiving or sending rent payments involving a sanctioned person is a criminal offence — and ignorance is no defence.
The penalties? Up to £1 million in fines, criminal prosecution, and potential director disqualification. There has already been a case where a company was fined specifically for checking at the start of a tenancy and missing a sanctions listing that came later. A one-off check is not enough.
What agentOS does for you
OFSI in a Box runs daily automated checks of your landlords, tenants, guarantors, buyers and vendors against the UK sanctions list — every 24 hours, without you having to do a thing. If there's a match, you're alerted immediately so you can act.
This matters because someone who was clear on day one can appear on the sanctions list mid-tenancy. Without ongoing monitoring, you'd have no idea — and every payment made or received in the meantime is a potential breach.
Since launching in June 2025, we've identified many tenants, landlords, buyers and sellers with a 95%+ match on the sanctions register across agencies throughout the UK. We've even confirmed full 100% matches — with those clients notified and findings reported directly to OFSI.

Who's covered?
Everyone who is a financial counterparty in your portfolio — landlords, tenants, guarantors, buyers, vendors. It's available across agentOS CRM, agentPay, and Calmony client bank accounts.
What does it cost?
Just 20p per person per month. Low cost, high impact — and a straightforward way to demonstrate ongoing due diligence to banks, regulators and professional bodies.
Many agents pass this cost directly to landlords as a standard compliance charge.
