Account Frozen? Account Freezing Orders and the First 72 Hours
By Jackson Ng MCIArb · Partner & Barrister · 18 July 2026
If your UK bank account has been frozen, the freeze is usually an Account Freezing Order (AFO), made under section 303Z1 of the Proceeds of Crime Act 2002 (POCA). Law enforcement - typically the National Crime Agency, HMRC, the SFO or the FCA - applies to the Magistrates' Court without notice to you, and the court grants the order if there are reasonable grounds to suspect the funds are recoverable property or intended for unlawful use. There is no fixed statutory deadline for your response, but in practice the first two to four weeks are decisive: how you respond, and the evidence you provide, can determine whether the matter is resolved, settled, or escalated into civil recovery proceedings.
What an AFO is
An AFO freezes the funds in an account in place - it does not seize them outright. The initial order typically lasts six months and can be extended, up to a cumulative maximum of two years, while the investigation continues. During that period the enforcement agency can apply under Part 5 of POCA to bring civil recovery proceedings against the funds, decide to release them, or negotiate a resolution. Because the order is made without notice, the account holder has no opportunity to be heard before the freeze takes effect - the first real opportunity to respond comes afterwards, by applying to vary or discharge the order.
Why accounts connected to China-related transfers get frozen
A recurring pattern involves funds reaching the UK through informal RMB-sterling remittance arrangements - sometimes called underground banking or currency-exchange circles - used to work around China's annual foreign-exchange conversion limits, or through daigou-style trading where a UK account receives a high volume of payments from Chinese customers. Tier 1 Investor visa funds can also be caught, where the Home Office or NCA revisits the source of investment capital years later. In many cases the underlying funds are entirely legitimate - proceeds of a property sale, dividends, or an inheritance - but the informal channel or receipt pattern is what triggers a bank's Suspicious Activity Report and, in turn, the enforcement agency's application. Legitimacy of the funds and reasonable suspicion under POCA are different legal questions; satisfying yourself of the first does not answer the second.
The first 72 hours: what to do and not do
Do: instruct solicitors with POCA experience immediately; begin assembling a source-of-funds evidence chain, from the original legitimate source through to the frozen account, with contemporaneous supporting documents; and treat the account as frozen until a court says otherwise. Do not: assume the freeze is temporary and will lift on its own - the enforcement agency will typically keep investigating throughout the initial period; try to resolve matters by contacting the bank or the enforcement agency directly and unrepresented, since banks generally have no power to lift an AFO and enforcement agencies rarely engage substantively with an unrepresented account holder; or submit overseas source-of-funds documents without proper certification, which can significantly reduce their evidential weight in an English court.
How AFO proceedings run
An account holder can apply to vary the order - for example, to release funds for legal fees, living expenses or ordinary business costs - or to discharge it entirely. Where the enforcement agency instead pursues forfeiture, or opens civil recovery proceedings under Part 5 of POCA, the case is decided on the civil standard - the balance of probabilities - rather than the criminal standard of beyond reasonable doubt. Assets can be recovered, or a contested discharge can fail, without any criminal conviction and without the account holder ever having been charged. A properly evidenced application - not a bare assertion that the freeze is wrong - is what tends to determine whether an agency drops the matter, settles, or proceeds to a contested hearing.
