Our regulatory audit methodology: stages, timelines, deliverables
We run a five-stage audit that fits UK regulators’ expectations. Discovery defines scope and risks, fieldwork tests design and operating effectiveness, reporting summarises issues with root causes, remediation closes gaps with owners and deadlines, and follow-up confirms fixes are embedded.

- Scoping and risk assessment, week 1: Confirm obligations under FCA, HMRC and Companies Act 2006. Map processes and controls, set materiality, and agree samples.
- Fieldwork, weeks 2–3: Walkthroughs, evidence requests and control testing across finance, tax and operational areas.
- Reporting, week 4: Issue-rated report with clear findings, evidence references and regulator alignment.
- Remediation, weeks 5–8: Action plan with owners, timelines and policy updates.
- Follow-up testing, weeks 9–10: Verify closure and update the risk register.
Deliverables include a signed audit report, detailed findings log, a remediation tracker, and board-ready summaries that link issues to FCA SYSC themes, HMRC guidance and Companies Act duties. Governance items that require board attention are flagged for your Corporate Governance agenda, and acquisition-related risks can feed into Due Diligence.
What we cover: UK regulators and standards mapped
Our Regulatory Audit Services test design and operating effectiveness against specific UK rules. Each finding cites the exact clause or guidance so remediation is precise and defensible during inspection or inquiry.

- FCA: SYSC control requirements, COBS disclosures, financial crime systems and controls, client money and safeguarding where relevant.
- HMRC: VAT process controls, corporation tax provisioning and documentation, PAYE/RTI processes, record-keeping and Making Tax Digital readiness.
- Companies Act 2006: director duties, accounting records, strategic report and s.172 considerations in governance processes.
- UK GAAP and IFRS: accounting policies, estimates and disclosures for financial statements, with handoff to Financial Statement Audit if statutory assurance is required.
- AML: CDD/KYC procedures, risk scoring, transaction monitoring and SAR handling.
- Healthcare: CQC fundamental standards mapped to governance and incident reporting.
- Environmental: Environmental Protection Act obligations, emissions and CRC legacy reporting controls.
- Incident and fraud: escalation paths, investigations and evidence integrity with support from Forensic Audit when needed.
You receive a testing matrix that links each control to the regulator, rule reference, evidence obtained and result.
Services overview
Here is how our UK-focused audits are packaged. Each engagement can be delivered as a one-off deep dive or as part of a quarterly compliance cycle. We assign a senior auditor, define scope and samples, then report issues with clear owners, timelines and regulator mapping.
We offer compliance audits, financial reporting reviews, tax compliance audits, internal control evaluations, environmental compliance audits, fraud risk audits and sector-specific regulatory audits. If you need continuous oversight after remediation, our Risk Management team can monitor key controls. For finance function improvements that arise from audit findings, consider Virtual CFO Services to embed stronger processes.

Compliance audits
We assess how policies, controls and records align with FCA rules, HMRC guidance and Companies Act 2006. Testing covers design and operating effectiveness, with samples drawn from real transactions and approvals. You receive issue-rated findings, regulator references and a remediation tracker. Governance actions are flagged for your board and audit committee, with links to Corporate Governance updates that keep policies, delegations and minutes inspection-ready.

Financial reporting audits (UK GAAP/IFRS)
We review accounting policies, key estimates and disclosures against UK GAAP and IFRS, then test close processes, reconciliations and journal controls. Findings reference specific standards and disclosure items so fixes are targeted before year-end. If statutory assurance is required, we coordinate scope and timing with our Financial Statement Audit team to avoid duplicate requests and keep your reporting timetable intact.

Tax compliance audits (VAT, CT, PAYE)
We examine VAT coding and evidence, corporation tax calculations and provisioning, and PAYE/RTI submissions against HMRC guidance. Sampling focuses on higher-risk transactions, adjustments and reliefs. The report highlights potential exposures, process weaknesses and documentation gaps. If HMRC opens an enquiry, our guide to the top tax investigation specialists in the UK explains what to expect. Where planning or elections are advisable, we hand off to Tax Advisory for Entrepreneurs to implement compliant improvements that reduce future risk.

Internal control evaluation
We test control design and operating effectiveness across order-to-cash, procure-to-pay, record-to-report and payroll. Evidence includes walkthroughs, approvals, access reviews and exception reporting. You receive a control matrix with ratings, residual risks and quick wins. When resource constraints hinder fixes, our Outsourced Financial Director service can own remediation and train your team so improvements stick.

Environmental compliance audits
We review obligations under the Environmental Protection Act, emissions reporting and sustainability disclosures. Testing covers permits, monitoring logs, incident reporting and supplier controls. Findings include regulator references, required evidence and corrective actions. Where ongoing monitoring is needed, our Risk Management team can implement KPIs and dashboards that track compliance and trigger escalation before deadlines are missed.

Fraud risk audits
We assess fraud exposure across payments, payroll, expense claims and vendor management. Work includes access and segregation reviews, anomaly testing, whistleblowing channels and third-party risk. Results rank scenarios by likelihood and impact, then assign owners and controls. Where suspected incidents arise, we coordinate discreet investigations with Forensic Audit, preserving evidence chains and reporting suitable for insurers and authorities.

Sector-specific regulatory audits
Finance: FCA SYSC, financial crime controls, client money and prudential reporting where applicable. We align findings to governance packs and board attestations.
Healthcare: CQC standards mapped to incident reporting, staffing, safeguarding and records. For clinical billing controls, see our health finance support for dentists.
Manufacturing: product quality, health and safety procedures, environmental permits and supply-chain evidence.
For acquirers and sellers, our sector audits feed straight into M&A workstreams so deal risks and remediation are known before completion.

- Detailed remediation plan outlining how to resolve identified compliance issues.
- Hands-on support for implementing corrective actions and updating policies.

Tools, platforms and data security
We collect and test evidence using secure, UK-hosted workflows. Access is role-based and time-limited, and all client materials are encrypted in transit and at rest. Our workpapers reference the exact test, population and sample so your board and regulators can follow the chain.
Tools we commonly use:
- Evidence intake and tracking: encrypted portals with audit trails.
- Data analysis: spreadsheet models plus validated scripts for exception testing.
- Collaboration: controlled shared workspaces with version history.
- Security: MFA, IP allow-listing and least-privilege access on all audit files.
Senior reviewers sign off on every working paper. Meet the practitioners who design these controls on our team page.

Pricing and engagement models
Pricing depends on scope, regulator coverage and number of processes sampled. Most UK Regulatory Audit Services are fixed-fee with a defined findings log and a follow-up review. We confirm scope up front, then hold pricing unless you add areas mid-engagement.
Typical models:
- Fixed-fee regulatory audit: £9,500 to £24,000 for an SME covering FCA, HMRC and Companies Act processes.
- Add-on sector modules: £3,000 to £6,500 each for AML, CQC or environmental testing.
- Quarterly compliance cycle: bespoke fee with reduced day rates and scheduled follow-ups.
What drives price: entity count, data complexity, evidence quality and remediation support required. Where audits reveal finance function gaps, our Virtual CFO Services can implement fixes. For a tailored proposal, Book a Call.
Comparison: regulatory audit vs statutory financial audit
A regulatory audit is an independent review of processes and controls against UK rules, while a statutory financial audit provides assurance on the truth and fairness of financial statements. Use this table to determine which assurance you need and when both apply.
| Aspect | Regulatory audit | Statutory financial audit |
|---|---|---|
| Primary focus | Compliance with FCA, HMRC, Companies Act and sector rules | Opinion on financial statements under UK GAAP/IFRS |
| Object of testing | Processes, controls, records, evidence | Balances, transactions, disclosures |
| Output | Findings log, remediation plan, follow-up | Audit opinion, management letter |
| Frequency | Risk-based or periodic | Annual if thresholds met |
| When to choose | Preparing for inspections or reducing compliance risk | Company meets audit thresholds or stakeholders require assurance |
If you need statutory assurance, coordinate with our Financial Statement Audit team.

UK case study and testimonial
A payments firm preparing for an FCA visit asked us to review client-money reconciliations, financial crime controls and governance papers. We identified 3 high-severity and 10 medium findings, implemented a remediation tracker, and closed 92% within 60 days. The FCA visit concluded with no supervisory action and clear next steps for BAU monitoring.
Pearl Lemon Accountants gave us clear findings and a simple plan. Ownership was obvious, and their follow-up kept us on track. We have stronger controls and cleaner documentation now.
Post-audit, our Risk Management team monitors key indicators to prevent drift.
Frequently asked questions
A regulatory audit is an independent review of processes, controls and records against UK rules, such as FCA handbook sections, HMRC guidance and the Companies Act. The output is a findings log with evidence references, regulator mapping and a remediation plan your team can implement.
Most SME audits complete in four to six weeks from kickoff to report, with two to four additional weeks for follow-up testing. Duration depends on scope, data quality and availability of process owners to supply evidence and review findings.
We usually request process maps, policies, control logs, samples of transactions, reconciliations, approvals, board papers and training records. For FCA-regulated firms we add SYSC, financial crime and client-money evidence. A short request list is issued at kickoff so owners can prepare.
Yes, because a statutory audit opines on financial statements, not compliance processes. A regulatory audit focuses on controls and evidence against FCA, HMRC and sector rules. If statutory assurance is needed as well, we coordinate with Financial Statement Audit to avoid duplicate work.
We minimise disruption by batching evidence requests and using secure portals. Workshops are short and scheduled. Fieldwork focuses on samples and walkthroughs, and we document precisely what we need so owners can respond quickly.
We rate issues by severity and likelihood, assign owners and due dates, and track closure. Each finding includes root cause, risk, required evidence and test steps for validation. Governance items can flow into Corporate Governance updates for board review.
We perform follow-up testing to confirm fixes are operating, then update the risk register. Many clients choose a quarterly review cadence and KPI monitoring to prevent recurrence. If you want a tailored plan, Book a Call.
