A UK subsidiary of a global group receives a payment-system alert: a customer account has been flagged against the UK Consolidated List, and the funds are frozen. The compliance team faces questions that must be answered quickly and correctly. Can the customer access any funds at all? Does the firm need to report to the Office of Financial Sanctions Implementation? How does this interact with the parallel OFAC or EU designation status of the same individual? As of June 2026, the answer to each of those questions carries legal weight – and getting it wrong can expose both the firm and its officers to civil and criminal liability.
Frozen-account management under OFSI means the structured set of steps a firm must follow once it identifies funds or economic resources belonging to, or owned or controlled by, a designated person under UK financial sanctions. OFSI administers financial sanctions under the Sanctions and Anti-Money Laundering Act ("SAMLA") and the relevant thematic sanctions regulations. The reporting obligation to OFSI is immediate upon knowledge or reasonable cause to suspect a sanctions breach: the statutory window is short, and delay is itself a compliance failure. Cross-border businesses must also assess whether parallel OFAC, EU, or SECO designations apply – because stricter prohibitions across regimes govern which activities remain lawful.
This guide walks through the mandatory steps – from the initial freeze and triage, through the reporting duty, to the licensing question and the record-keeping obligation – with a comparison to the approach taken by OFAC and the EU.
Step 1: Identify and freeze – what does the OFSI prohibition actually catch?
The first obligation is to identify correctly what is frozen and to prevent any dealing with the frozen funds or economic resources. OFSI's financial sanctions prohibit any person in the United Kingdom – and any UK person anywhere in the world – from dealing with, or making available, funds or economic resources owned, held, or controlled by a designated person. The prohibition is broad. It applies regardless of whether the designated person is the sole account holder or whether the funds are held jointly or through an intermediary structure.
Firms regularly misread the scope. "Dealing" is not limited to payment or transfer. It includes any act that changes the value, volume, location, or ownership of the asset. A mere set-off, a fee deduction, a foreign-exchange conversion, or the rolling of a deposit into a new instrument may all constitute a prohibited dealing if the underlying account holder is designated. In our experience, the most common early mistake is treating the freeze as a simple payment block while continuing to apply interest or fees to the account – activities that constitute dealings in themselves.
The second identification question is whether non-listed entities are caught by the ownership and control test (the UK and EU test for whether a non-listed entity is caught through a listed person). Under OFSI, an entity that is owned or controlled by a designated person is itself subject to the same prohibitions. Ownership means holding more than 50 percent of the shares or voting rights. Control is assessed on a broader, qualitative basis – whether the designated person can, directly or indirectly, determine or materially influence the actions of the entity. That control limb is wider than OFAC's purely mechanical 50-percent aggregate ownership rule. A counterparty that sits below the ownership threshold may still be caught under OFSI's control analysis, and a firm that screens only for direct ownership will miss it.
Step 2: Report to OFSI – when, how, and what?
The duty to report arises as soon as a relevant firm knows, or has reasonable cause to suspect, that a person is a designated person, or that the firm holds frozen funds or economic resources belonging to such a person. The SAMLA regime imposes this as a positive legal duty on relevant firms: it is not discretionary, and it is not contingent on a completed internal investigation. Firms should submit the report while simultaneously continuing their internal review, not wait until that review is finished.
What must the report contain? OFSI expects the identity of the account holder, the amount and nature of the frozen funds or economic resources, the basis of the designation, and the steps the firm has already taken. Submitting an incomplete report is better than submitting nothing, but an incomplete report that misidentifies the designated person or misstates the amount of frozen funds creates its own risks. Have you kept a full record of what was known at each stage – including the screening alert, the escalation, and the decision to report?
There is a cross-border dimension. A UK-headquartered bank with branches or subsidiaries in EU member states or the United States will face separate and distinct reporting duties to the relevant EU national competent authority and, in the US context, to OFAC. The timelines and formats differ. OFAC does not impose a statutory reporting duty in the same form as OFSI's, but a blocked-property interest must be reported annually. EU regimes generally require prompt notification to the relevant national authority. Where a firm operates across these jurisdictions, reports must be filed under each applicable regime independently – the OFSI submission does not discharge the EU or US obligation, and vice versa.

The position above covers the standard reporting case. Your facts – the designation basis, the nationality of the account holder, the nature of the frozen asset, the jurisdictions in which the firm operates – change the analysis materially.

Step 3: Assess licensing – can any dealings be authorised?
A specific licence (a case-by-case authorisation to conduct an otherwise prohibited transaction) can permit a dealing that would otherwise breach the financial-sanctions prohibition. OFSI has power to grant specific licences across a range of licensing grounds. Common grounds relevant to frozen accounts include the payment of reasonable legal fees and expenses; the satisfaction of basic living expenses of the designated person or their dependants; and the satisfaction of pre-existing contractual obligations that arose before the designation.
Licensing is not a rubber stamp. OFSI will assess whether the dealing falls within the claimed ground, whether the amount is proportionate, and whether there are conditions appropriate to attach. In our practice, applications that fail to specify precisely how the ground is met – and what safeguards the applicant proposes – are returned or refused at much higher rates than those that address the ground in detail and pre-empt obvious questions.
The distinction between OFSI and OFAC licensing is practically significant for cross-border businesses. Under OFAC, a general licence (a standing authorisation that permits a defined category of transactions without a separate application) may cover categories of dealings that OFSI has not authorised by general licence. The EU regime, similarly, contains provisions in the relevant Council Regulation that authorise certain dealings in frozen funds for defined purposes, without requiring a case-by-case application in every instance. A firm that operates only on the basis of an OFAC general licence without checking whether OFSI has issued an equivalent will be exposed to liability under the UK regime.
Conversely, an OFSI specific licence does not authorise a dealing prohibited under OFAC or EU law. Each licence is regime-specific. The stricter prohibition governs. In our experience, this is the most frequently misunderstood aspect of multi-jurisdictional frozen-account management: practitioners assume that a licence granted in one jurisdiction provides a measure of comfort in another, when it does not.
If a transaction has already been flagged, or a licence application has been refused, an early review can preserve options that narrow with time. Contact Calder & Vance at info@caldervance.com to discuss your position.
Step 4: Manage the account lawfully during the freeze period
Once the account is frozen and the report has been submitted, the firm must manage the frozen asset in a manner that is consistent with the prohibition. This is not passive. Permitted and prohibited activities must be identified and documented on an ongoing basis throughout the freeze period, which may extend for months or years.
What remains permitted without a licence? Generally: maintaining the frozen asset in a segregated account, accruing interest where the interest itself is credited to and frozen in the same account, and communicating with the designated person to explain their designation status and the steps required to seek a licence. What requires a licence? Everything else that would constitute a dealing – including fee deductions, charges, set-offs, and any payment to or from the account.
The record-keeping obligation runs throughout. Firms must retain adequate records of all steps taken in relation to a frozen account: the screening result, the escalation, the report to OFSI, any licensing application and decision, and all communications with the account holder. OFSI's enforcement guidance makes clear that inadequate record-keeping is a factor that weighs against a firm in an enforcement assessment. Retaining records for at least five years from the relevant transaction or event is consistent with established UK financial-crime record-keeping standards, and is the minimum prudent approach, though firms should verify the current position under the applicable regime.
During the freeze period, firms should also monitor for changes in the designation status of the account holder. Designations under OFSI are maintained on the UK Consolidated List. A delisting – whether through OFSI's own administrative review, a judicial-review challenge, or a UN de-listing process in the case of UN-mandated designations – terminates the prohibition in respect of the delisted person. The firm must be positioned to act promptly when a delisting occurs: continuing to treat an account as frozen after a valid delisting is itself a potential compliance failure.
Step 5: Address the cross-border dimension – where OFSI, OFAC, and the EU diverge
For firms operating across multiple jurisdictions, frozen-account management requires tracking three separate sets of obligations that can apply to the same account holder simultaneously and that do not mirror each other.
The central divergence lies in the designation lists and the legal tests. A person designated by OFSI may not be designated by OFAC. A person on the EU Consolidated List may not appear on the UK Consolidated List following the UK's departure from the EU. Since UK and EU sanctions regimes have diverged, the lists are no longer maintained in lock-step. Firms that assume UK and EU designations remain equivalent are operating on an incorrect basis.
The ownership and control tests also diverge in ways that affect which accounts are frozen. As noted in Step 1, OFSI applies both an ownership limb and a broader control limb. OFAC's test is purely mechanical: 50 percent or more aggregate ownership by one or more blocked persons causes the entity to be treated as blocked, regardless of control. The EU approach mirrors OFSI's in applying both an ownership and a control limb, but the implementing regulation and the guidance from the relevant national competent authority should be checked in each member state, since application is not always uniform. Switzerland (SECO), Singapore, and Japan each maintain their own designation lists and their own tests, which again differ from OFSI's in scope and detail.
In a recent matter, a financial institution managing accounts for a group of companies discovered that the parent company had been designated by OFSI but not by OFAC. The subsidiary accounts, held in the United Kingdom, were frozen under OFSI's control test. The same subsidiary accounts, had they been held at a US branch, would not have been blocked under OFAC's 50-percent rule because the parent's stake in the subsidiary was below the aggregate threshold. We assessed the position under both regimes, identified the precise scope of frozen assets in each jurisdiction, and assisted the institution in preparing the OFSI report and a licence application for specific categories of continued operation. The matter illustrated that a compliance team working only from one regime's rules will systematically misjudge the position across the others.
Step 6: Risk flags and when to involve sanctions counsel
Several fact patterns substantially elevate the risk in a frozen-account matter and require early involvement of sanctions counsel rather than reliance on standard compliance procedures alone.
The first is a designation of uncertain provenance. If a firm cannot immediately verify whether the screening alert reflects a current, valid designation on the UK Consolidated List – as opposed to a false positive, a name-match error, or a superseded designation – the risk of both over-blocking (treating an undesignated person as designated) and under-blocking (releasing funds that should be frozen) is high. Both directions of error carry legal exposure.
The second is a complex ownership structure. Where the apparent account holder is a corporate entity and the designation applies to an upstream shareholder, the ownership-and-control analysis is fact-intensive. Firms that lack the capacity to trace and map the ownership chain to the required depth should seek external analysis before releasing or freezing the account.
The third is a request from the account holder for access to funds. Designated persons and their representatives often contact the holding firm seeking access under a humanitarian or legal-fees exception. Responding without first establishing whether a licence ground is available, and whether a licence application is required, risks either unlawful payment or unlawful denial of authorised access. Both outcomes generate regulatory exposure.
The fourth is a concurrent OFAC, EU, or other-regime designation. As the cross-border section sets out, multi-regime designations require multi-regime compliance assessments. A firm that has not checked all applicable regimes before taking any action on a frozen account – including the report, the licence application, and any communications with the account holder – may satisfy one regime while breaching another.
A widely held view among compliance teams is that a report to OFSI discharges the firm's obligations while the licensing position is worked out. This is not accurate. The report and the licensing question run in parallel, not in sequence. Submitting the report does not suspend the prohibition on dealings, and it does not extend time for a licence application. Firms that operate on the assumption that submission of the OFSI report puts them in a safe holding position may find that dealings continuing during the review period – fee deductions, set-offs, account maintenance charges – constitute unreported breaches running in parallel with the reported one.
