TL;DR: A Section 166 skilled person review is an operationally intense, expensive regulatory process that firms under FCA supervision must fund entirely themselves, with direct costs ranging from £70,000 to £150,000 for smaller firms and into the millions for larger banks. The FCA triggers reviews when it identifies systemic documentation gaps and controls failures, not isolated advice errors. Running automated compliance checks across 100% of your advice files before the review begins means genuine documentation gaps are identified and remediated through a documented process, so the review starts from a file population where known issues have already been addressed and a forward-looking compliance process is in place to prevent new ones. Firms with documented, systematic compliance control enter the review with a remediated file population and a clear evidence trail showing governance was in place before the review began.

This playbook covers the operational triggers, costs, timeline, and file-preparation framework firms need to prepare for a Section 166 review. It is written for Operations Directors, compliance leads, and senior advisers at FCA-regulated advice firms who want to understand how a skilled person review unfolds, what a skilled person looks for in a sampled client file, and where documentation gaps are most likely to surface. The six preparation steps draw on the same compliance standards a skilled person applies, so firms can assess their current file population against that standard before a Requirement Notice arrives. The content here is for operational hygiene and educational purposes only and does not constitute formal legal advice.

What Triggers an FCA Section 166 Review

Key Scenarios for Skilled Person Reviews

A Section 166 review is a formal regulatory tool the FCA uses when it identifies material weaknesses it cannot resolve through standard supervision alone. The FCA commissions an independent skilled person, under the FCA's skilled person review powers, to report on specific aspects of a firm's activities, systems, or controls.

In the wealth management and multi-practice advice context, the scenarios most likely to trigger a review include:

• High volumes of defined benefit pension transfers where the FCA identifies systemic suitability failures across a large number of client files

• Consumer Duty evidencing failures, where the FCA concludes a firm cannot demonstrate the four retail customer outcomes across its advice files

• AML and financial crime failures, including gaps in AML documentation or sanctions screening

• SMCR governance failures, particularly in multi-adviser firms where senior management oversight of adviser conduct cannot be evidenced

• Significant consumer harm indicators emerging from complaints data or thematic reviews

Operational Red Flags for the FCA

Before a formal Section 166 notice arrives, the FCA typically identifies operational indicators during standard supervision. These patterns accelerate regulatory scrutiny for a multi-practice firm:

• A sudden spike in client complaints, particularly those referencing unsuitable recommendations or inadequate explanations of charges, which can signal underlying systemic issues

• High adviser turnover creating documentation gaps as client relationships transfer between advisers with inconsistent file quality

• Inconsistent file-turnaround times across offices or adviser teams, which may signal fragmented workflows rather than systematic controls

• Back-office data gaps where client records in Intelliflo, Plannr, Curo, or Xplan do not match the advice documentation held on file

• Poor evidencing of ongoing service delivery against fees charged, which is a primary Consumer Duty concern under PRIN 2A.4

For Operations Directors managing multi-adviser firms, systemic inconsistency across your team often carries greater regulatory weight than any single poor advice file.

Key Differences from Standard Supervision

A standard supervisory visit is collaborative. The FCA raises concerns, the firm responds, and the regulator monitors progress. A Section 166 review is categorically different across three dimensions.

First, it is independent: the skilled person's obligations run to the FCA and they must produce findings that are independent, objective, and complete. When a firm appoints the skilled person, the report goes to both the firm and the FCA, though the firm receives it primarily for factual challenge before final submission. Second, the power derives from Section 166 of FSMA, with the appointment and conduct process set out in SUP 5 of the FCA Handbook. Third, it is funded entirely by the firm under review.

Target Areas for Your Regulatory Review

Audit Proofing Your Documentation

When an adviser writes meeting notes from a blank page after every client conversation, documentation quality varies with their seniority, their workload that day, and their individual interpretation of what to capture. When Evie records the meeting and generates structured notes, the documentation standard becomes consistent regardless of which adviser conducted the meeting.

Evie shifts the adviser from author to editor, so the audit trail builds by design rather than retrospectively. You can explore how this works in our guide to AI-assisted suitability reports. Evie connects directly with back-office systems including Intelliflo, Plannr, Curo, and Xplan, pushing structured meeting outputs directly into the fact-find. Evie populates specific fields including personal information, investment details, and employment details, eliminating manual data entry. The integration workflow is detailed in our Intelliflo integration guide.

Proving Consumer Duty Compliance

Consumer Duty, introduced under Principle 12 and PRIN 2A in July 2023, requires firms to evidence four retail customer outcomes across every client relationship: products and services (PRIN 2A.3), price and value (PRIN 2A.4), consumer understanding (PRIN 2A.5), and consumer support (PRIN 2A.6). A skilled person does not accept a firm's assertion that clients received good outcomes. They look for documented evidence in each client file.

Under PRIN 2A.4, your files need documented comparisons of charges against alternative products, clear justification for any active management fees versus passive alternatives, and a service level assessment matching the stated ongoing charges. Critically, the FCA's Consumer Duty approach means firms must proactively consider remedial action when harm is identified, even without a client complaint.

Benchmarking Your Suitability Reports

COBS 9.4.7R sets the minimum requirements for suitability reports: the client's demands and needs, an explanation of why the recommendation is suitable, and an explanation of any disadvantages of the transaction for the client. A skilled person benchmarks every sampled report against this standard.

We designed Emma to generate suitability reports directly from the firm's existing templates rather than imposing a standardised format. Your established, compliance-checked document formats already reflect your firm's interpretation of COBS requirements, and Emma preserves that investment while ensuring every adviser produces reports to the same structural standard. A suitability report is only as strong as the fact-find behind it: every claim should trace back to a specific data point, with the client's objectives appearing in both documents in consistent language. You can explore our AI-assisted suitability report generation in more detail.

Checklist for Advice File Integrity

Use this pre-emptive audit checklist to assess your current file standard before engaging any external review support:

How to Prepare Your Firm Before the Review

1. Stress-Test Your Advice Files

Your compliance officer reviewing 50 files from a population of 5,000 is covering 1% of the firm's advice. The other 99% is unexamined until a skilled person examines it for you.

We designed Colin, our system-agnostic compliance checker, to run 42 automated checks on suitability reports and multi-category checks on fact-finds. Because Colin is system-agnostic, you can apply the same standard to your entire existing file population, not just documents created after adoption. Colin produces colour-coded pass/fail verdicts per category with a percentage compliance score, alongside specific remediation guidance for every failed check.

2. Standardise Documentation Across Advisers

When documentation quality varies materially across your adviser team, a skilled person cannot establish a consistent standard of advice delivery. This is a systemic finding, and systemic findings carry heavier regulatory consequences than individual file failures.

Evie and Emma standardise meeting note and suitability report output at the point of production. Every adviser, from the most experienced planner to a recently promoted associate, produces structured notes covering the same categories and generates suitability reports following the firm's established template. As explored in our suitability letter simplification guide, documentation consistency is your primary defence against a systemic finding.

3. Verify Meeting Note Accuracy

Brief meeting summaries written hours after a complex financial planning conversation create two risks for a Section 166 review. They are incomplete, because memory degrades quickly. They are unverifiable, because there is no primary source to cross-reference against the file note.

Evie records client meetings and generates structured notes directly from the recording. Our meeting notes workflow also captures soft facts including client anxieties, family dynamics, and other relevant context. This richer evidence is what compliance officers and skilled persons look for when assessing whether clients genuinely understood the advice given. At Wayne's firm One FS, Evie flagged 'hard of hearing' as a potential vulnerability indicator during a meeting. When clients decline recording consent, our client consent guidance covers how to maintain productivity without losing documentation quality.

4. Align Reports with FCA Standards

Every report in a skilled person's sample must clearly justify why a recommended transaction is in the client's best interest compared to retaining their existing arrangement. This is particularly important for platform transfers, pension transfers, and investment switches, where the additional transaction costs must be weighed explicitly against the benefits.

Emma cites statements in the suitability report back to source documents, whether that is the meeting notes, fact-find, LOA pack summaries, ceding information, cashflow modelling outputs, or risk profile assessments. This creates a traceable connection between client instruction and adviser recommendation at every step, which is exactly what COBS 9.4.7R requires. Our AI suitability reports for pension transfers guide explains how this applies to high-scrutiny transfer cases specifically.

5. Confirm Consumer Duty Readiness

You cannot evidence Consumer Duty compliance after the fact during a review. You must build it into the documentation at the point of advice delivery. Colin checks documents against FCA Consumer Duty requirements and COBS standards before they leave the adviser's desk, providing specific remediation guidance where gaps exist. A failed check reads "Add AML check documentation" or "Include executive summary with key recommendations," and the adviser corrects the file immediately rather than discovering the gap during an audit.

6. Structure Your Documentation Trail

Atlas integrates with SharePoint and back-office systems including Intelliflo and Plannr to support document retrieval and client file management. During a skilled person review, advisers and operations staff can retrieve and present structured client information directly through Atlas, reducing the manual effort of document collation.

Atlas's Adaptive Thinking feature, released May 2026, makes this reasoning visible at every step: advisers can see the process Atlas followed to retrieve and connect information, and expand any thinking block to review the full reasoning behind a given answer, with reasoning persisting across sessions so earlier queries remain auditable. Atlas remembers client preferences and instructions across sessions, so the context behind a file builds up rather than resetting each time an adviser returns to it. Fund and product research capability is on the Atlas roadmap, alongside DFM and model-portfolio comparison and plain-English workflow automations. Firms should confirm current availability directly with AdvisoryAI.

The structured, source-cited audit trail that Evie, Emma, and Colin produce means the skilled person can verify the connection between client instruction and advice outcome at each step.

Recurring Compliance Issues in Skilled Person Reviews

Skilled person reviews in wealth management consistently surface the same four operational failures. Understanding them before a review is far more effective than remediating them during one.

• Fragmented firmwide records: Individual advisers using different approaches to meeting notes, different interpretations of fact-find completeness, and different standards for suitability report narrative depth can create documentation inconsistency. When every adviser uses the same Evie-generated note structure and Emma-generated report template, the skilled person sees a consistent documentation standard rather than a patchwork of individual approaches.

• Missing client profile data: Fact-find gaps often include incomplete vulnerability assessments with no documentation of specific support provided, missing financial literacy ratings, unrecorded foreseeable life changes, and absent behavioural bias identification. Colin's automated review process checks for these gaps across every file.

• Retrospective documentation risks: Rewriting historical meeting notes to fill identified gaps can carry regulatory risk. A skilled person may be able to identify documentation written retrospectively, which can create an integrity concern. The better approach is to use available recordings or supervised adviser recollections to reconstruct accurate records, and to put in place a forward-looking process using Evie that eliminates these gaps from all new meetings.

• Value evidencing gaps: Skilled persons pay particular attention to whether the firm has documented that charges clients pay are justified by the benefits they receive. Our whitepaper on documentation automation references research showing annual review time can be reduced by 59.8% when end-to-end documentation workflow changes are in place, freeing compliance resource to focus on value quality rather than file volume.

Stages of the Formal FCA Review Timeline

Typical Section 166 Timeline and Operational Milestones

Defining the Section 166 Review Scope

The Requirement Notice defines what the skilled person will and will not review, the specific questions they have been asked to answer, their methodology, and the timeline. The scope must be agreed between the firm, the skilled person, and the FCA before the review begins, as set out in SUP 5 of the FCA Handbook.

The Requirement Notice defines the sample size, the file selection criteria, and the business areas under review. Engaging competent legal and compliance counsel at this stage can influence the scope and, therefore, the total cost of the review.

Optimising Your Sample File Selection

The skilled person selects a sample of client files to audit against the agreed scope and methodology. If errors appear in the initial sample, they may expand the review scope, and that expansion can increase both the duration and the cost of the process. This is the primary mechanism through which a contained review escalates.

When you have run automated compliance checks across your entire file population before the review begins, known gaps have been identified and remediated through a documented process. The skilled person draws from a file population where genuine issues have already been caught and corrected, and a forward-looking compliance process is in place to prevent new ones arising.

Key Questions During Your S166 Review

The skilled person will ask senior management and advisers a structured set of questions covering:

1. Governance and oversight: How does senior management monitor documentation quality and advice standards across all advisers?

2. File review processes: What internal file review cadence exists, who conducts those reviews, and how are findings escalated?

3. Consumer Duty implementation: How does the firm evidence the four Consumer Duty outcomes at file level and firm level?

4. Complaints handling: How are complaints identified, escalated, and documented, and how are thematic patterns addressed?

5. Systems and controls: What technology manages documentation workflows, how are those systems audited, and what security certifications does the firm hold (Cyber Essentials, ISO 27001)? Firms whose documentation workflows include Colin's automated pre-submission checks can answer the last question with a documented, systematic process.

Addressing Findings and Compliance Gaps

The draft report phase is the critical window where senior management can challenge inaccurate findings before the final report is submitted to the FCA. Firms should ensure senior management reviews the draft report with legal counsel and submits a formal, evidence-based response to any contested findings.

You must base your challenge response on documented facts. The skilled person will not revise a finding based on verbal disagreement. You need evidence: client files, compliance check records, and documented remediation steps that prove the finding is incorrect or that remediation has already occurred.

How to Improve Documentation Quality Quickly

Align Templates for Section 166 Readiness

We configured Emma to work from the firm's existing document structure, not a standardised vendor format. A dedicated team of ex-paraplanners and advisers configures Emma to match the firm's exact formatting and section structure within two weeks of engagement. Our workflow optimisation guide explains how this configuration process handles firms with multiple client proposition formats.

Cut Admin Hours with AI Automation

A Section 166 review requires significant internal resource: pulling files, responding to information requests, preparing management information, and supporting the skilled person's interviews. If your advisers and paraplanners are spending 4-6 hours per suitability report and 1.5 hours on every set of meeting notes, that time is not available for review support.

Brooks Macdonald freed 6,000 hours annually across 60 advisers with Evie, cutting meeting write-up time from 2.5 hours to a 30-minute review. The AdvisoryAI whitepaper references research showing annual review time can be reduced by 59.8% when end-to-end documentation workflow changes are in place. That recovered resource is directly available to support a Section 166 information gathering process.

Ensure File Readiness Before Sign-Off

Every suitability report should pass through Colin's 42 automated checks, with fact-finds and file notes running multi-category checks, before the adviser sends them to the client or uploads them to the back office. Failed checks generate specific remediation guidance, the adviser corrects the gap and resubmits, and only files that pass Colin's checks enter the back office and the formal advice record. This quality control operates across high-volume document workflows, catching inconsistencies at the adviser desk rather than at audit.

All three capabilities are available on a monthly rolling agreement with no lock-in, with a 14-day free trial, a 30-day money-back guarantee, and a 10% discount on annual plans.

Essential Guidance for Your Section 166 Review

Typical Section 166 Review Timelines

Based on observed industry experience, a Section 166 review typically runs between 3 and 9 months from the initial Requirement Notice to the final report submission, covering the six operational phases summarised in AdvisoryAI's framework above. Reviews involving historical file analysis across multiple offices, or financial crime investigations requiring forensic data extraction, can extend well beyond 12 months.

The key variable is the information gathering phase. Firms with well-organised, digitally accessible client files and a documented compliance checking process move through this phase significantly faster than firms relying on fragmented digital archives across multiple systems.

Managing Section 166 Review Expenses

The firm under review is legally required to fund all skilled person expenses under SUP 5 of the FCA Handbook. Direct costs vary widely with scope. Reported figures from GKSB Consultancy put smaller-firm reviews in the region of £70,000 to £150,000, with reviews at larger banks running into the millions. Between 2017 and 2021, regulated firms incurred £21.7 million across 65 financial-crime-focused reviews, and insurers and insurance intermediaries incurred £2.7 million in costs for skilled person reviews in March 2024.

Beyond direct skilled person fees, firms must account for substantial internal resource costs including senior management time, legal and compliance counsel, documentation collation, and any interim business restrictions the FCA imposes during the review such as client onboarding freezes. These ranges reflect reported industry data, and your actual costs will vary based on the complexity of your firm's structure and the scope of the review.

Rules for Selecting a Skilled Person

Under SUP 5.4, a firm can nominate a skilled person for FCA approval, or the FCA may appoint one directly. The firm's right to nominate is practically significant because selecting a skilled person with specific wealth management expertise can help ensure the review applies standards appropriate to the advice sector.

Handling Unsuccessful Review Findings

If a skilled person's final report identifies systemic failures, the consequences escalate quickly. Critical failures can trigger FCA requirements under Section 55L of FSMA, voluntary requirements agreed with the firm, or formal enforcement referrals. In severe cases, client onboarding restrictions may apply while remediation is assessed.

The most effective mitigation is a robust, immediate, and evidence-based remediation plan with named owners, specific timelines, and measurable milestones. A finding followed by immediate, evidenced remediation carries significantly less regulatory risk than a finding the firm contests without evidence.

As Regulatory Counsel notes, firms should treat the report's recommendations as mandatory in practice, because failure to act on them will be viewed negatively in any future supervisory engagement.

Why Documentation Infrastructure Matters Beyond the Review

This matters beyond compliance defensibility: just 9% of UK adults received financial advice on their pensions or investments in the 12 months to May 2024, while 62% of investors would welcome more help managing their investments, rising to 68% when reviewing them. The bottleneck is documentation capacity, not advice expertise.

Firms that build systematic compliance control through Colin, Evie, Emma, and Atlas protect their capacity to serve clients rather than restricting it to manage regulatory risk manually. Colin, Evie, and Emma are each capabilities within the Atlas platform, so the audit trail, compliance checks, and meeting notes all sit within a single documented system.

Demonstrating AI Governance to a Skilled Person

A defensible advice file lets a reviewer check every statement back to its source. Emma cites each statement in a suitability report back to its source document, whether that is the fact-find, meeting notes, LOA pack summary, or cashflow modelling output, so the connection between client instruction and advice outcome is verifiable at every step.

Some compliance officers raise a legitimate concern about AI capabilities in an FCA-regulated context: if a regulator asks how a recommendation was reached, can the firm demonstrate the reasoning? The answer depends on whether your documentation platform records the link between a statement and its evidence, which is the record an FCA file review actually needs, or whether it records only the prompt and output. Atlas records the former.

Client data is stored on UK-based AWS servers and is not used to train models. For advisers weighing whether AI belongs in a regulated advice workflow at all, AdvisoryAI's CEO has addressed this question directly in an external conversation with Intelliflo, covering specifically why documentation automation does not replace professional judgment. AdvisoryAI's model was trained on thousands of sample reports by ex-advisers and paraplanners, and our CTO holds an MIT Masters in AI/ML, providing the technical foundation for regulatory defensibility.

For a skilled person reviewing how the firm's AI capabilities processed client information, Atlas shows its reasoning in plain English through Adaptive Thinking, so a reviewer can see how any answer was reached rather than facing an opaque conclusion. As our AdvisoryAI vs ChatGPT comparison explains, this is oversight infrastructure, not a novelty feature.

Request a demo to see how Atlas's documented reasoning and Colin's automated compliance checks hold up against the questions a skilled person asks. No credit card is required for a 14-day free trial, and a 30-day money-back guarantee applies to paid plans.

FAQs

How long does an FCA Section 166 skilled person review typically take?

Based on observed industry experience, a Section 166 review typically takes between 3 and 9 months from the initial scoping phase to the final report submission, with complex multi-office or financial crime reviews extending beyond 12 months. The duration depends primarily on the complexity of the firm's advice files and how efficiently the operations team can retrieve and present documentation during the information gathering phase.

Who pays for a Section 166 skilled person review and what are the typical costs?

The firm under review is legally required to fund all skilled person expenses under SUP 5 of the FCA Handbook, with smaller-firm reviews reported in the region of £70,000 to £150,000 and reviews at larger banks running into the millions, per GKSB Consultancy. Firms must also account for substantial internal resource costs, legal and compliance counsel, documentation collation, and any interim business restrictions the FCA imposes during the review such as client onboarding freezes. These ranges reflect reported industry data, and your actual costs will vary based on the complexity of your firm's structure and the scope of the review.

Can a firm select its own skilled person for an FCA review?

Yes, under SUP 5.4, a firm can nominate a skilled person for FCA approval before the review begins, or the FCA may appoint one directly. Selecting a skilled person with specific wealth management expertise is critical for ensuring the review applies standards appropriate to the advice sector.

What is the draft report phase and why does it matter?

The draft report phase is the period after the skilled person completes information gathering and before they submit their final report to the FCA, when the firm has a documented opportunity to challenge factual inaccuracies with evidence. This is the most critical window for senior management to correct the record, and firms should engage legal and compliance counsel to review every finding and submit a formal, evidence-based response.

What happens if a Section 166 review identifies systemic failures?

Systemic failures identified in a skilled person's final report can lead to FCA requirements under Section 55L of FSMA, voluntary requirements agreed with the firm, formal enforcement referrals, or business restrictions such as client onboarding freezes. A robust, documented remediation plan with named owners, timelines, and FCA progress updates is the most effective mitigation against escalating regulatory consequences.

Does Colin work on reports created outside AdvisoryAI?

Yes, we designed Colin to be system-agnostic, meaning it checks any suitability report, fact-find, or file note regardless of which platform produced it. This makes it practical to run automated compliance checks across an existing file population without first migrating documentation to a new system.
