UK OFSI Sanctions Lawyer
The UK's Office of Financial Sanctions Implementation imposes designations independent of EU sanctions since Brexit. We challenge UK listings, apply for OFSI licences, and advise on UK sanctions compliance.
📋 On This Page
Since Brexit the UK runs an autonomous sanctions regime under SAMLA 2018, administered by OFSI (HM Treasury) — separate from both the EU and US regimes.
- A UK designation freezes all UK-held funds and economic resources and imposes a travel ban; UK persons cannot make funds available to the designated person.
- UK and EU/US lists overlap but are not identical — a person can be on one and not the others.
- Challenge routes: OFSI administrative review, ministerial review (some programmes), and judicial review before the UK High Court.
- OFSI licences can authorise legal fees, basic needs, prior contracts and humanitarian transactions.
- Multiple designations require parallel challenges — OFSI (UK), CJEU (EU) and OFAC petition (US).
UK Sanctions Post-Brexit — The OFSI Regime
Since Brexit, the UK has operated its own independent sanctions regime under the Sanctions and Anti-Money Laundering Act 2018 (SAMLA). The Office of Financial Sanctions Implementation (OFSI), part of HM Treasury, administers and enforces UK financial sanctions. The UK Consolidated List of financial sanctions targets is maintained separately from EU sanctions lists.
Challenging UK OFSI Designations
UK designations can be challenged by:
- Ministerial review — requesting reconsideration by the Minister for Financial Sanctions
- Judicial review — challenging the designation in the UK courts on public law grounds
- Court of Justice challenge — for designations that mirror EU listings, challenging the EU listing can influence the UK position
The UK court system has increasingly scrutinised the evidential basis for sanctions designations. We prepare detailed submissions challenging the factual and legal basis for UK listings and coordinate with UK-qualified counsel.
| UK challenge route | Forum / grounds |
|---|---|
| Administrative review | OFSI reconsiders — designation based on incorrect facts or made without proper basis |
| Ministerial review | Reconsideration by the Minister for Financial Sanctions (some programmes) |
| Judicial review | UK High Court — illegality, irrationality, procedural unfairness |
OFSI Licence Applications
OFSI issues licences that permit specific transactions involving UK-designated persons. Licence categories include: legal fees, basic needs, prior contractual obligations, and extraordinary humanitarian situations. We prepare OFSI licence applications with full supporting documentation.
The UK Sanctions Regime Post-Brexit
The United Kingdom departed the European Union in January 2020. Before Brexit, UK sanctions were implemented as part of the EU’s Common Foreign and Security Policy. After Brexit, the UK enacted the Sanctions and Anti-Money Laundering Act 2018 (SAMLA), which provides the legal basis for the UK’s autonomous sanctions regime. The Office of Financial Sanctions Implementation (OFSI), part of HM Treasury, administers UK financial sanctions and maintains the UK consolidated list of designated persons.
The UK sanctions regime now operates independently of the EU regime. While there is significant overlap — particularly on Russia, Iran, and terrorism-related programs — UK and EU designations are not identical. A person can be designated by the UK but not the EU, or vice versa. The challenge processes are also distinct: UK designations are challenged through OFSI’s administrative review and, if necessary, UK judicial review proceedings before the High Court.
Consequences of UK OFSI Designation
A UK OFSI designation results in an immediate asset freeze covering all funds and economic resources held in the UK or by UK persons anywhere in the world. UK persons (including UK banks, law firms, and businesses) are prohibited from making funds or economic resources available to designated persons. A UK travel ban prohibits entry to or transit through the United Kingdom. The combined effect of a UK designation — particularly when combined with US OFAC and EU designations — is a near-total exclusion from the global financial system for individuals with UK banking or commercial relationships.
For individuals with significant UK financial or business connections — property in the UK, accounts with UK banks or their foreign subsidiaries, business partners in the UK — a UK OFSI designation can be as damaging as a US OFAC designation. UK banks, due to their exposure to the US dollar clearing system, frequently align their compliance with OFAC standards in addition to UK OFSI requirements.
Challenging UK OFSI Designations
The UK provides two formal routes to challenge an OFSI designation: an administrative review by OFSI itself, and judicial review before the UK High Court. A Ministerial review is also available in some programs. The administrative review requires demonstrating that the designation decision was based on factually incorrect information or was made without proper basis under the applicable sanctions regulations. Judicial review applies the standard public law grounds — illegality, irrationality, and procedural unfairness — to the designation decision.
Delisting from UK sanctions requires either a formal review decision to delist, a sunset clause expiry (where applicable under the specific sanctions program), or a successful judicial review overturning the designation. In some programs, the designating minister has discretion to remove a designation where circumstances have changed materially. Our Cyprus-based lawyers coordinate UK OFSI challenges with specialist UK solicitors, providing integrated advice on EU, UK, and US simultaneous designations.
UK OFSI vs US OFAC vs EU
| Regime | Administered by | Challenge route |
|---|---|---|
| UK — OFSI | HM Treasury (SAMLA 2018) | OFSI review / UK High Court judicial review |
| US — OFAC | US Treasury | Administrative reconsideration (delisting) petition |
| EU | EU Council | Annulment before the CJEU |
Frequently Asked Questions
OFSI (Office of Financial Sanctions Implementation) is the UK body that administers UK financial sanctions, part of HM Treasury. OFAC (Office of Foreign Assets Control) is the equivalent US body. Both administer financial sanctions — asset freezes and transaction prohibitions — but under separate legal regimes with separate designated persons lists. A person can be on one list but not the other, and the challenge processes are entirely different. Since Brexit, the UK and EU also operate separate sanctions regimes.
Yes. OFSI has the power to issue licences authorising specific transactions involving designated persons. Available licence categories include basic living expenses, legal fees, ongoing contractual obligations entered into before designation, and humanitarian purposes. Licence applications require a detailed factual submission. We assist with UK OFSI licence applications, including emergency applications where access to funds for living expenses or legal fees is urgently needed.
UK OFSI designations can be challenged by judicial review before the Administrative Court (part of the King’s Bench Division of the High Court of England and Wales). The grounds for judicial review are: illegality (the designation was made without proper legal basis); irrationality (the decision was irrational in light of the available evidence); and procedural unfairness (the designated person was not given a proper opportunity to make representations). UK courts have annulled sanctions designations on these grounds. Permission to apply for judicial review must be obtained first.
There is significant coordination but also meaningful divergence. The UK, EU, and US typically designate the same persons in connection with major programs like Russia, Iran, and North Korea. However, there are differences in both the lists and the procedures. A person designated by all three authorities needs to pursue three separate challenge processes — OFSI review/judicial review (UK), CJEU annulment proceedings (EU), and OFAC delisting petition (US). We advise on coordinated multi-regime challenges.
The UK currently administers sanctions programs covering Russia and Belarus, Iran, North Korea, Myanmar, Venezuela, Syria, Zimbabwe, the Western Balkans, Afghanistan, Central African Republic, and many others — including thematic programs on counter-terrorism, cyber operations, and human rights. Some programs are directly inherited from pre-Brexit EU designations; others have been newly created under SAMLA. The UK consolidated list is maintained at gov.uk/government/publications/financial-sanctions-consolidated-list-of-targets.
