T+1 Settlement for UK AIFMs in 2027: Guide to AML Compliance and AML Software Readiness

Last updated: June 2026

Introduction: why T+1 matters for UK AIFMs

T+1 means that in-scope securities trades settle one business day after the trade date, rather than two as before. The UK market is moving to T+1 settlement on 11 October 2027, with the FCA explaining that the change aims to make financial markets more efficient and reduce risk.

For UK Alternative Investment Fund Managers, T+1 is not a new AML rule. It does, however, compress operational timelines. Investor onboarding, beneficial ownership checks, sanctions and PEP screening, source of funds review, exception handling, and audit evidence all become harder to manage when post-trade and cash movement processes are under greater time pressure.

For AIFMs managing hedge funds, private credit, real estate, private equity, infrastructure, or multi-asset strategies, the key question is practical: can your AML control framework operate at the speed your trading, settlement, and investor operations will now require?

UK regulatory framework for T+1 and AML

T+1 settlement framework

HM Treasury has confirmed that it intends to legislate to make T+1 the standard settlement cycle in the UK from 11 October 2027. The related policy note states that, on that date, the T+1 requirement is scheduled to become law under UK CSDR.

The FCA expects firms to have engaged with the Accelerated Settlement Taskforce recommendations, completed T+1 project plans, secured necessary budget, made system and process changes, and be ready to test those changes by the end of 2026. The FCA also says it may take action to protect market integrity if firms are not prepared for the October 2027 deadline.

AML framework for UK AIFMs

UK AML obligations remain grounded in the Money Laundering Regulations 2017, the Proceeds of Crime Act 2002 and the Terrorism Act 2000. The FCA summarises core expectations for supervised firms as risk assessment, appropriate systems and controls, due diligence, MLRO appointment and senior responsibility for AML systems and controls.

FCA Handbook SYSC 6.3 requires firms to maintain systems and controls that identify, assess, monitor and manage money laundering risk, and that are proportionate to the nature, scale and complexity of the firm’s activities. It also expects regular assessment of those systems and controls.

For asset management and alternatives firms, the FCA has specifically highlighted financial crime risks linked to private assets and complex ownership structures. Its 2025 portfolio letter says proportionate, risk-based investor due diligence and robust KYC checks are particularly important for identifying ultimate beneficial owners, and that the FCA will focus on AML controls in private markets funds where it identifies weaknesses.

What T+1 means for AML teams at UK AIFMs

T+1 does not remove the need for careful AML review. It reduces the tolerance for manual bottlenecks.

Under a T+2 environment, firms often had more breathing room to resolve missing KYC documents, clarify investor ownership, review screening hits or escalate unusual payment behaviour. Under T+1, the same issues may collide more quickly with trade settlement, subscription processing, redemption payments, liquidity management and counterparty workflows.

For AML teams, this creates four practical pressures:

Earlier completion of onboarding checks: investor and counterparty files should be complete before activity creates settlement pressure.
Cleaner data at source: incorrect names, fragmented ownership data and outdated risk ratings can cause avoidable screening and review delays.
Faster alert handling: PEP, sanctions and adverse media alerts need clear ownership, escalation paths and evidence.
Better management information: MLROs and senior managers need visibility over unresolved high-risk files, overdue reviews, outsourced controls and settlement-linked exceptions.

Obligations and pressure points by AIFM model

Private equity, venture capital and private credit AIFMs

Private market AIFMs often deal with layered corporate structures, holding vehicles, trusts, family offices and cross-border investors. These structures may require deeper UBO analysis, source of wealth review and source of funds evidence.

The FCA has linked private asset growth with financial crime risks involving complex ownership structures, making this a priority area for alternatives firms.

Hedge funds and liquid alternatives

Hedge funds and liquid alternatives may be closer to the direct operational impact of T+1 because their strategies can involve frequent trading, prime brokerage, collateral movements, financing arrangements and rapid cash flows.

AML teams should ensure that investor risk ratings, counterparty files, sanctions screening and transaction monitoring logic are aligned with the faster operational rhythm. T+1 readiness should not sit only with operations or trading desks.

Real estate and infrastructure AIFMs

Real estate and infrastructure funds may face slower-moving asset cycles, but AML complexity can still be high. Investors may use holding companies, nominee structures or offshore entities. Where the fund also holds transferable securities or manages liquidity buffers, T+1 may affect treasury and settlement processes alongside investor due diligence.

Fund administrators, delegates and outsourced service providers

Many AIFMs rely on administrators, transfer agents, depositaries, screening vendors or other outsourced providers. The FCA’s asset management portfolio letter stresses the importance of effective oversight where controls are outsourced.

AIFMs should review service-level agreements, escalation timings, data ownership, evidence access and reporting formats before T+1 testing begins.

A risk-based approach to T+1 AML readiness

The FCA expects AML resources to be focused where they have the biggest impact, with practices varying according to the money laundering risks firms face and the products they sell.

For UK AIFMs, a sensible T+1 AML risk assessment should consider:

Which funds trade in securities likely to be affected by T+1
Which investor types create the highest onboarding or review complexity
Which jurisdictions, ownership structures or payment routes create higher AML exposure
Which outsourced providers control key AML evidence or screening activity
Which manual processes could delay settlement, subscription or redemption workflows
Which management reports show unresolved AML risk before it becomes operational risk

This is also an opportunity to update the firm-wide business risk assessment, fund-level risk assessments and AML procedures. The JMLSG guidance supports a risk-based approach that gives firms discretion in applying UK AML and CTF requirements according to their products, services, transactions and customers.

FAQ: T+1 settlement and AML for UK AIFMs

Does T+1 create new AML obligations for UK AIFMs?

No. T+1 changes the securities settlement cycle, not the core AML legal framework. The AML impact is operational: firms may need faster, cleaner and better-evidenced controls to meet existing obligations under compressed timelines.

When does T+1 start in the UK?

The UK market is moving to T+1 settlement on 11 October 2027. HM Treasury has confirmed its intention to legislate for T+1 as the standard settlement cycle from that date.

Should the MLRO be involved in the T+1 project?

Yes. The MLRO should understand whether faster settlement creates AML control gaps, especially around onboarding, screening, transaction monitoring, outsourced controls and evidence retrieval.

Is T+1 relevant to private market AIFMs?

Yes, although the impact varies by fund strategy. Private market AIFMs may feel less direct trading pressure than liquid funds, but they still face AML scrutiny around complex ownership structures, investor due diligence, outsourced controls and audit evidence.

Can AML software guarantee T+1 compliance?

No. AML software can support workflows, evidence, screening, monitoring and reporting, but it does not replace legal judgement, regulatory interpretation or senior management accountability.
