UK sanctions checks for letting agents

Financial sanctions are not a paperwork exercise bolted to the end of a referencing checklist. They are a prohibition. It is an offence to make funds or economic resources available, directly or indirectly, to a person designated under UK sanctions regulations — and a tenancy makes both available. Rent is funds. A home someone is allowed to occupy is an economic resource. Held deposits are funds. That is why the screening duty reached letting agents rather than staying with banks and conveyancers, and it is why the answer to "how much rent triggers this?" is: none, the duty does not work that way.

Who you must screen

Since 14 May 2025 UK letting agents must screen all landlords, tenants and guarantors against the UK sanctions list, at any rent level, and must report suspected designated persons to OFSI — the Office of Financial Sanctions Implementation, part of HM Treasury. Three roles, three different reasons:

• Landlords receive the rent. Passing rent to a designated landlord, or holding it for them, is making funds available.
• Tenants receive the property. Letting a designated person occupy a home is making an economic resource available to them, whoever pays the rent.
• Guarantors stand behind the obligation and may end up paying it, so they are inside the same money flow as the tenant.

Two extensions are easy to miss. Where a party is a company, a partnership or a trust, a designation can bite through ownership or control rather than by naming the entity you are dealing with, so a corporate landlord needs its beneficial owners considered rather than just its registered name run through a search box. And a party who is added later — an occupant moving in, a replacement guarantor, a new director of a corporate landlord — is a new screening event, not a variation of an old one.

When to screen

Screen before money moves or keys change hands. In practice, that means at the point you have a name and identifiers you believe in, and before the first payment is taken or the tenancy is granted, whichever comes first. Then screen again:

• at renewal, and on any material change of party;
• when a new occupant, guarantor or corporate officer appears;
• continuously, for the life of the tenancy, because designations are made between your checks.

The last one is the part most processes get wrong. A screening result is a statement about one list edition at one moment. If the only screen on file is dated at referencing, the file says nothing about the eight months that followed. Ongoing monitoring — re-screening saved subjects each time a list is republished — is what turns a one-off search into a position you can actually stand behind.

Which list, and what changed

The UK Sanctions List is published by the Foreign, Commonwealth & Development Office and names every person, entity and ship designated under UK sanctions regulations, with the regime each designation sits under. On 28 January 2026 the separate OFSI consolidated list closed, making the UK Sanctions List the single UK source. If any part of your process still points at the retired consolidated list file, it is reading a file nobody updates any more — the detail is in what changed when the OFSI consolidated list closed.

Screening the US OFAC SDN list and the EU consolidated list alongside it is not a UK legal requirement, but it is cheap and it is often the difference between a surprise and a decision — particularly where rent is paid from a US dollar or euro account, where a corporate landlord has an EU parent, or where a guarantor is resident abroad.

What a screen has to leave behind

Assume that in two years someone asks you to prove you screened a tenant you have since forgotten. To answer, the record must carry:

1. The subject as you screened them — name as entered, plus any date of birth and nationality you used, and their role in the tenancy.
2. The list editions — which publication of each list, and when your system took it in. "We use a screening tool" is not an answer; "we screened against the UK Sanctions List as published on that date" is.
3. The timestamp and the operator — when the check ran, in a timezone that does not move, and who ran it.
4. The outcome and the reasoning — the result, anything the search returned, and the human conclusion about it. A score is a prompt to look, never a decision.
5. A retention position — how long the record is kept and what happens at the end of it, because holding identity data indefinitely creates a different problem.

Why name matching is harder than it looks

Names on sanctions lists arrive transliterated from other scripts, often in several competing spellings, sometimes with the family name first, frequently with patronymics that a UK form has no field for, and usually with a pile of aliases of varying reliability. An exact-string search across that data is not caution — it is a way of producing a clean answer that means nothing. Useful screening has to tolerate spelling variants, reversed name order and missing middle names, then score how close each candidate actually is, and hand the borderline cases to a person. The method is set out in how to screen a tenant against the UK Sanctions List.

The trade-off is unavoidable: loosen the matching and you review more false positives; tighten it and you miss the transliteration you had not thought of. Reviewing a handful of near-misses per hundred tenancies is a cost worth paying, and it is why every match needs a human decision recorded against it rather than a silent dismissal.

When something matches

Do not proceed on the strength of a score alone, and do not tell the subject you are checking them. Compare the match detail against the documents you hold — date of birth and nationality are usually decisive — and record what you concluded. If it still looks like the same person, the tenancy stops being a lettings problem and becomes a reporting one: do not make funds or economic resources available, and report to OFSI as soon as practicable. The sequence, including the tipping-off trap, is in reporting a sanctions match to OFSI.

What good looks like, in one paragraph

Every landlord, tenant and guarantor screened before money moved, against a named edition of the UK Sanctions List and the two international lists, with the result, the reviewer and the reasoning on the file; saved subjects re-screened automatically whenever a list is republished; a dated certificate for each check that an inspector can verify independently; and a retention rule that eventually deletes it all. None of that is exotic. It is just impossible to reconstruct after the fact, which is why it has to be produced at the time.

Frequently asked questions

Is there a rent threshold below which I do not have to screen?

No. Since 14 May 2025 UK letting agents must screen all landlords, tenants and guarantors against the UK sanctions list at any rent level. Financial sanctions bind every person in the UK, so there is no rent figure to fall under and no exemption for a single tenancy or a private landlord.

Which list should a letting agent screen against?

The UK Sanctions List, which since 28 January 2026 is the single UK source of designations following the closure of the OFSI consolidated list. Many agents also screen the US OFAC SDN list and the EU consolidated list, which is useful where funds, landlords or guarantors have a US or EU connection.

What evidence do I need to keep after a screening?

Enough to reconstruct the check later: who you screened and with which identifiers, which list editions you screened against, the date and time, the outcome, and the reasoning behind any decision that a possible match was not the person in front of you. A result with no record of the list edition behind it cannot be defended a year later.

Does a clear screening result stay valid for the whole tenancy?

No. A screening result is only as current as the list edition it was run against, and designations are added between your checks. A no-match at referencing says nothing about the position eight months later, which is why saved subjects should be re-screened whenever a list is republished.

SafeLet screens against the UK Sanctions List, the US OFAC SDN list and the EU consolidated list. It is a screening aid, not legal advice, and it does not cover politically exposed persons or adverse media. Every possible match requires human review, and suspected designated persons must be reported to OFSI.
