Nominated officer
A nominated officer is the person a UK firm appoints to receive internal reports of suspected money laundering or terrorist financing from staff, and decide whether to pass them on to the National Crime Agency as a suspicious activity report. The role comes from the Money Laundering Regulations 2017 and the Proceeds of Crime Act 2002. Most firms use the term interchangeably with MLRO, though the two aren’t identical in every jurisdiction.
Key takeaways
- A nominated officer receives internal reports of suspected money laundering and decides whether to file an external SAR with the NCA.
- The role comes from regulation 21(3) of the Money Laundering Regulations 2017 and Part 7 of POCA 2002.
- In everyday use, “nominated officer” and “MLRO” mean the same person.
- The MLCO is a separate, board-level role accountable for the firm’s overall AML compliance, not the same job.
- Failing to report a suspicion that should have been reported can mean up to 5 years in prison under POCA.
- The definition isn’t universal: Guernsey’s nominated officer only covers the MLRO’s absence, a narrower role than the UK version.

What a nominated officer actually does
The nominated officer sits at the centre of a firm’s internal reporting chain. When a member of staff suspects money laundering or terrorist financing, they don’t go straight to the National Crime Agency. They report it internally, to the nominated officer, first.
From there, the nominated officer reviews what’s been reported, decides whether it meets the threshold for suspicion, and files a suspicious activity report with the NCA if it does. If it doesn’t, they record the decision and the reasoning behind it.
That makes the role a filter, not a passthrough. A firm that reports everything without evaluating it, or one that fails to report things that clearly warrant it, both fall short of what the regulations expect.
Where the role comes from
The legal requirement sits in two places. Regulation 21(3) of the Money Laundering Regulations 2017 requires firms in the regulated sector to appoint an individual as nominated officer. Regulation 3 defines the term: someone nominated to receive disclosures under Part 3 of the Terrorism Act 2000 and Part 7 of the Proceeds of Crime Act 2002.
POCA creates the underlying reporting offence. Under sections 330 to 332, failing to disclose a suspicion of money laundering, when you’re in a position where you should have known, is a criminal offence in its own right, separate from the laundering itself.
Nominated officer vs MLRO: the practical answer
In everyday use, nominated officer and MLRO mean the same person doing the same job. MLRO, or money laundering reporting officer, is the common industry name for whoever holds the statutory nominated officer position. Most policies, job titles, and regulator correspondence say MLRO, even though the regulations themselves say nominated officer.
Sole practitioners with no staff are the main exception. Regulation 21 doesn’t require a nominated officer where there’s nobody internal to report to in the first place.
Nominated officer vs MLCO: the real distinction
The genuine split is between the nominated officer and the MLCO, the money laundering compliance officer. Regulation 21(1) requires a separate, board-level appointment: someone senior who’s accountable for the firm’s overall compliance with the Money Laundering Regulations.
The nominated officer’s job is narrower and operational: receive internal reports, decide on external SARs. The MLCO’s job is broader: policies, procedures, training, and the firm’s whole AML framework. In smaller firms, one person often holds both roles. In larger, FCA-regulated firms, they’re frequently split, with the MLRO holding the formal SMF17 senior management function.
What happens after a staff member reports something
Once a report reaches the nominated officer, the clock starts. They review the facts, decide whether a genuine suspicion exists, and act on that decision without unnecessary delay.
If they file an external SAR, the firm generally can’t proceed with the transaction in question until it gets consent from the NCA, or a set time limit passes. Staff who reported the original concern also need to stay quiet about it. Tipping off the customer, even by accident, is a separate criminal offence.
Personal liability: why the role carries weight
The nominated officer carries personal criminal exposure, not just professional risk. Under POCA, failing to disclose a suspicion that should have been reported can mean a fine and up to five years in prison.
That’s a meaningful part of why firms take the appointment seriously, and why the role tends to go to someone experienced rather than whoever happens to be free. Getting the call wrong, in either direction, has consequences that land on the individual, not just the firm.
Deputies and cover arrangements
Every firm needs a plan for when the nominated officer is away. Larger organisations often appoint one or more deputies of sufficient seniority to step in during absences, with clear internal guidance on when that authority applies.
Smaller firms typically name a single deputy in their AML policy. What matters to a regulator is that the arrangement is documented, and that staff know exactly who to report to at any given time rather than being left to guess.
How the role differs outside the UK
The UK’s version of the role isn’t universal. In Guernsey, for example, the nominated officer is defined narrowly as cover for the MLRO’s absence, not the primary decision-maker. Anyone drafting AML policy across UK and Channel Islands entities needs to check the local definition rather than assume it carries over.
That’s a genuine trap for group compliance functions managing policy across multiple jurisdictions. The same job title can mean a materially different scope of responsibility depending on where the entity is regulated.

Frequently asked questions
What is a nominated officer?
A nominated officer is the person a UK firm appoints to receive internal reports of suspected money laundering or terrorist financing and decide whether to file a suspicious activity report with the National Crime Agency. The role is required under regulation 21(3) of the Money Laundering Regulations 2017.
Is a nominated officer the same as an MLRO?
In practice, yes. MLRO is the common industry name for whoever holds the statutory nominated officer position. The regulations say “nominated officer”; firms and regulators generally say MLRO.
What’s the difference between a nominated officer and an MLCO?
The nominated officer’s job is operational: receive internal reports, decide on external SARs. The MLCO is a separate, board-level appointment accountable for the firm’s overall compliance with the Money Laundering Regulations. Smaller firms often combine both roles in one person.
What happens if a nominated officer fails to report a suspicion?
They can face a fine and up to five years in prison under the Proceeds of Crime Act 2002, separate from any consequences for the firm itself.
Does every firm need a nominated officer?
Firms in the regulated sector generally do. The main exception is a sole practitioner with no staff and nobody else to report to, since regulation 21 doesn’t apply where there’s no one internal to make a disclosure to.
What happens after someone reports a suspicion internally?
The nominated officer reviews the facts, decides whether a genuine suspicion exists, and either files an external SAR with the NCA or records the decision not to. Staff involved must not tip off the customer while this happens.
Who covers for the nominated officer when they’re away?
Most firms appoint one or more deputies of sufficient seniority, documented in the firm’s AML policy, so staff always know who to report to.
Is the nominated officer role the same in every country?
No. In Guernsey, for example, the nominated officer only covers for the MLRO’s absence rather than acting as the primary decision-maker, a materially narrower scope than the UK definition.
