If you feel like the goalposts for Anti-Money Laundering (AML) compliance are constantly moving, you’re not alone. As we move through 2026, the UK accountancy sector is facing its most significant regulatory update in years. The Money Laundering and Terrorist Financing (Amendment) Regulations 2026 have officially arrived, and they bring a new level of scrutiny to how firms handle high-risk clients, trusts, and client money.
The good news? These changes aren't designed to make your life harder: they’re designed to make your compliance more targeted. By moving away from "blanket" checks and focusing on genuine risks, the 2026 rules actually offer a path to a more efficient practice.
At Streem Connect, we’ve spent months analyzing these updates to ensure our tools keep you ahead of the curve. Here is our actionable, 5-step guide to mastering the 2026 AML changes without the usual compliance-induced headache.
Step 1: Recalibrate Your Risk Assessment Logic
The biggest shift in 2026 is the narrowing of Enhanced Due Diligence (EDD) triggers. Previously, the law required EDD for any "complex or unusually large" transaction. The new wording is more specific: EDD is now required for transactions that are "unusually complex" AND "unusually large."
This might seem like a minor semantic tweak, but it’s a game-changer for your workload. It means you no longer have to perform exhaustive EDD on routine complex work that is standard for your sector.
Your Action Plan:
- Define "Unusual": Update your firm-wide risk assessment (FWRA) to define what constitutes "unusually large" or "unusually complex" specifically for your client base. What’s normal for a Big Four firm isn't normal for a local bookkeeper.
- Update Country Scoring: Mandatory EDD is now focused primarily on FATF "Black-list" countries (like North Korea or Iran). Ensure your software isn't automatically forcing you into EDD for every "Grey-list" country, though you should still consider them a risk factor.

Step 2: Revolutionise Your CDD with Automated Verification
With the 2026 changes placing more emphasis on Source of Funds (SoF) and Source of Wealth (SoW), manual checks are no longer just slow: they’re a liability. Chasing clients for paper statements or grainy PDFs is the quickest way to kill your firm’s productivity.
This is where the Streem Verify tool becomes your best friend. Instead of waiting days for a client to find their documents, you can verify their financial history in under 30 seconds.
Why automated verification is a must in 2026:
- Instant Accuracy: Use Open Banking to pull real-time data directly from the source. No more worrying about tampered PDFs or missing pages.
- Proof of Balance: Instantly verify that a client actually has the funds they claim to have.
- Seamless Client Experience: Your clients don't need to create an account. They simply click a link, authenticate with their bank, and you get a professional, structured SoF report.

Step 3: Tackle the New TCSP and Trust Regulations
The 2026 amendments have put a spotlight on Trust and Company Service Providers (TCSPs). If your firm forms companies or: more importantly: sells "off-the-shelf" companies, you are now explicitly within the scope of regulated TCSP activity.
Furthermore, the Trust Registration Service (TRS) has expanded. Many non-UK trusts that hold UK property acquired before October 2020 must now be registered.
How to stay compliant:
- Audit Your Formations: If you provide "ready-made" companies, ensure they are subject to full AML monitoring, record-keeping, and SAR (Suspicious Activity Report) protocols.
- Review Trust Portfolios: Check your client list for trusts that were previously exempt but may now fall under the new registration rules.
- Document the "De Minimis": The 2026 rules introduced exemptions for some low-risk, low-value trusts. Make sure you document why a trust isn't registered if you're using this exemption.
Step 4: Secure Your Pooled Client Accounts (PCA)
If you hold client money in pooled accounts (for example, to facilitate tax payments), the 2026 rules have "decoupled" these from Simplified Due Diligence. This means you can no longer assume a pooled account is low risk just because it’s a PCA.
The new "Reasonable Measures" standard:
You are now required to take reasonable measures to understand the purpose of every PCA you hold and implement controls to manage the associated risks.
- Transparency is Key: Keep clear records of whose money is in the pool and exactly what it is being used for.
- Automate Reconciliation: Use tools like Streem Reconcile to compare your internal transaction sheets against real-time bank data. This ensures your pooled accounts are always accurate and easy to audit during an HMRC inspection.

Step 5: Implement Continuous, Real-Time Monitoring
The era of "set it and forget it" compliance is over. The 2026 regulations emphasize ongoing monitoring. HMRC expects you to know if a client’s risk profile changes during the engagement, not just at the start.
In the past, this meant manual quarterly reviews. Today, it means automation. By using Open Banking links, you can maintain a live connection to your client's financial data.
The Benefits of a "Live" Compliance Workflow:
- Threshold Alerts: Set alerts to be notified if a client’s balance drops below a certain level or if they receive an unusually large credit.
- No More Chasing: Because the data flows automatically, you have an up-to-date audit trail without ever having to send a "reminder" email to your client.
- HMRC Ready: If an auditor asks for your records, you can pull a complete, categorised transaction history in seconds.

Conclusion: Don't Just Comply: Scale
Mastering the 2026 AML changes doesn't have to be a drain on your firm’s resources. In fact, if you use this update as an excuse to ditch manual spreadsheets and embrace tools like Streem Connect, you’ll likely find yourself with more time on your hands than you had before the regulations changed.
By following these five steps: recalibrating your risk logic, automating your CDD, auditing your technical services, securing your pooled accounts, and embracing real-time monitoring: you’ll move from "survival mode" to a practice that is secure, robust, and ready for the future.
