Auditing Services in the United Kingdom

UK companies exceeding statutory audit thresholds — or those required by lenders, investors, or regulators — must undergo audits conducted under International Standards on Auditing (UK) by a registered auditor.

Overview

Fintax Support Limited prepares audit-ready financial statements under FRS 102, compiles working papers, and coordinates with your statutory auditor to streamline the engagement. We also support charities requiring independent examination or full audit under Charity Commission regulations and assist with HMRC-led tax investigations requiring financial reconstruction.

Regulatory framework

UK private companies must appoint an auditor if they exceed two of three thresholds: £10.2 million turnover, £5.1 million balance sheet total, or 50 employees. Audit reports must comply with ISA (UK) and be filed with annual accounts at Companies House. The FRC regulates audit quality and can sanction firms for non-compliance.

Statutory Audits (ISAs UK-Compliant)

Prepare for statutory financial statement audits conducted under International Standards on Auditing (UK) issued by the Financial Reporting Council. We assemble FRS 102 financial statements, audit-ready working papers, and PBC schedules so your registered statutory auditor can issue an unmodified opinion efficiently — whether required by Companies Act 2006 Part 16 thresholds, lenders, or shareholders.

ISA (UK) working papers

How it works, details and FAQs

How it works

  1. 01

    Pre-audit readiness assessment

    Review prior-year audit findings, trial balance, and FRS 102 compliance gaps before fieldwork begins.

  2. 02

    Working paper preparation

    Compile PBC schedules, reconciliations, and disclosure drafts aligned to the auditor's engagement letter.

  3. 03

    Fieldwork support

    Respond to auditor inquiries, provide substantiation, and resolve testing exceptions during on-site or remote fieldwork.

  4. 04

    Report issuance coordination

    Finalise directors' report, going concern statement, and board approval for audit report and Companies House filing.

Statutory audits under ISA (UK) — issued by the Financial Reporting Council and overseen by the FRC's Audit, Reporting and Governance Authority — provide reasonable assurance that FRS 102 financial statements are free of material misstatement. Companies exceeding two of three thresholds — turnover £10.2 million, gross assets £5.1 million, or 50 employees — must appoint a registered auditor under Companies Act 2006 Part 16. We prepare audit-ready working papers including adjusted trial balances, account reconciliations, related-party disclosures, and going-concern analyses before your statutory auditor begins fieldwork. Proper preparation reduces billable audit hours, accelerates report issuance for lender covenant deadlines, and minimises repeat findings in subsequent years. Our team coordinates the entire PBC process from engagement letter review through to signing of the audit report filed at Companies House.

Common questions

02 / 09

Internal Audit & Management Review

Evaluate internal controls, operational processes, and financial reporting workflows through structured internal audit and management review programmes. Internal audit identifies control weaknesses before your statutory auditor or the FRC-regulated audit firm does — reducing fraud risk, qualified opinions, and operational inefficiencies across your UK organisation.

Control environment assessment

Process walkthrough testing

Deficiency identification

Management action plans

How it works, details and FAQs

How it works

  1. 01

    Risk assessment and scoping

    Identify high-risk processes, entity-level controls, and FRS 102-relevant areas based on your industry and size.

  2. 02

    Control documentation and testing

    Document key controls, perform walkthroughs, and test operating effectiveness over the review period.

  3. 03

    Findings report delivery

    Present internal audit findings to management and the board with severity classifications and root causes.

  4. 04

    Remediation tracking

    Monitor management's corrective actions through follow-up testing before statutory audit fieldwork.

Internal audit and management review services evaluate whether your organisation's controls over financial reporting and operations are designed and operating effectively. We apply the Three Lines Model and COSO principles widely referenced by UK audit firms when assessing control environments under ISA (UK) 315. Our engagements include entity-level control assessment, process walkthroughs for revenue recognition under FRS 102 Section 23, procurement and disbursement cycles, payroll controls, and IT general controls. Findings are classified by severity with clear remediation plans — the same discipline statutory auditors apply when evaluating control deficiencies during ISA (UK) fieldwork. Remediation before your statutory audit reduces the risk of qualified opinions, scope limitations, and repeat findings that increase audit costs year over year.

Common questions

03 / 09

Audit Exemption Threshold Review

Determine whether your UK company qualifies for statutory audit exemption under section 477 of the Companies Act 2006 or must appoint a registered auditor. We assess turnover, gross assets, and employee counts against current thresholds and document the exemption resolution for filing at Companies House.

Two-of-three threshold test

Section 477 exemption documentation

Group and subsidiary review

Lender and shareholder checks

How it works, details and FAQs

How it works

  1. 01

    Threshold data collection

    Gather turnover, gross asset, and average employee data from management accounts and payroll records.

  2. 02

    Exemption eligibility assessment

    Apply the two-of-three test under Companies Act 2006 Part 16 and review group, banking, and regulatory constraints.

  3. 03

    Directors' resolution preparation

    Draft section 477 exemption statement and shareholder notification where required by the company's articles.

  4. 04

    Companies House filing support

    File unaudited accounts with exemption statement and monitor threshold breaches for future periods.

Small companies may claim audit exemption under section 477 of the Companies Act 2006 if they qualify as small and do not exceed two of three thresholds: turnover £10.2 million, gross assets £5.1 million, or 50 employees on average. Companies must still prepare and file FRS 102 or FRS 105 accounts at Companies House — exemption removes the requirement for a registered auditor's opinion, not the obligation to produce true and fair accounts. Parent companies in a group, banking entities, insurance undertakings, and public companies cannot claim exemption. We assess eligibility annually, document the directors' exemption statement, and flag when approaching thresholds so you can plan for statutory audit costs. Lender covenants and investor agreements frequently override statutory exemption rights.

Common questions

Charity & Non-Profit Audits

Prepare for independent examination or full statutory audit of registered charities under Charity Commission requirements and the Charities SORP. We assemble trustee reports, fund accounting schedules, and restricted fund disclosures so your independent examiner or registered auditor can complete the engagement within filing deadlines.

Charity Commission compliance

Independent examination support

Full audit preparation

Restricted and designated funds

How it works, details and FAQs

How it works

  1. 01

    Reporting requirement assessment

    Determine whether independent examination or full audit applies based on income, assets, and Charity Commission rules.

  2. 02

    SORP accounts preparation

    Prepare Charities SORP-compliant accounts with fund analysis, trustee report, and required disclosures.

  3. 03

    Examiner or auditor workpaper assembly

    Compile bank reconciliations, grant income schedules, payroll records, and restricted fund movements.

  4. 04

    Charity Commission filing support

    Submit annual return and accounts to the Charity Commission within ten months of financial year-end.

Registered charities in England and Wales must prepare accounts under the Charities SORP, which applies FRS 102 with charity-specific disclosures. Charities with gross income exceeding £1 million require a full audit by a registered auditor. Charities with income over £250,000 and gross assets exceeding £3.26 million also require a full audit. Charities below these thresholds but above £25,000 income require an independent examination by a qualified independent examiner. We prepare SORP-compliant accounts, trustee annual reports, and fund accounting schedules distinguishing unrestricted, restricted, and endowment funds. Proper preparation ensures timely Charity Commission annual return submission — due ten months after year-end — and satisfies donor, grant-maker, and trustee governance requirements.

Common questions

05 / 09

Group Audit & Consolidation

Prepare consolidation schedules, intercompany eliminations, and group disclosure notes for UK group audits conducted under ISA (UK) 600. We compile subsidiary financial information, uniform accounting policies, and consolidation workings so your group auditor can test the consolidated FRS 102 accounts efficiently.

Intercompany eliminations

FRS 102 Section 9 consolidation

Component auditor coordination

How it works, details and FAQs

How it works

  1. 01

    Group structure mapping

    Document parent-subsidiary relationships, ownership percentages, and reporting currencies for each entity.

  2. 02

    Subsidiary information compilation

    Collect trial balances, adjustments, and statutory accounts from each group entity for consolidation.

  3. 03

    Consolidation workings preparation

    Prepare elimination entries, goodwill calculations, non-controlling interests, and uniform policy adjustments.

  4. 04

    Group auditor fieldwork support

    Respond to group auditor inquiries on consolidation judgements, related parties, and component audits.

Group audits under ISA (UK) 600 require the group engagement partner to direct and supervise component auditors and evaluate consolidated financial statements. UK parent companies must prepare consolidated accounts under FRS 102 Section 9 when they have subsidiaries, unless exempt as a small group under section 399 of the Companies Act 2006. We prepare consolidation schedules eliminating intercompany transactions, unrealised profits, and intra-group balances; apply uniform accounting policies across entities; and document non-controlling interests and goodwill impairment assessments. Component entity PBC packs are indexed for subsidiary auditors whose work the group auditor relies upon. Proper consolidation preparation supports group CT600 filings, transfer pricing documentation, and Companies House group accounts submission.

Common questions

06 / 09

Grant & Funding Compliance Audits

Prepare for grant compliance audits and funder-mandated assurance reviews required by UK public sector bodies, lottery distributors, and institutional funders. We assemble expenditure evidence, outcome reporting schedules, and restricted fund reconciliations so funders receive the assurance they require under grant agreement terms.

Grant expenditure reconciliation

Funder assurance preparation

Restricted fund compliance

Match funding verification

How it works, details and FAQs

How it works

  1. 01

    Grant agreement review

    Analyse funder terms, eligible cost definitions, reporting deadlines, and assurance requirements per grant.

  2. 02

    Expenditure tracking setup

    Configure nominal codes and restricted funds to segregate grant income and eligible expenditure by programme.

  3. 03

    Compliance evidence assembly

    Compile invoices, payroll allocations, outcome reports, and match funding evidence for auditor or funder review.

  4. 04

    Assurance engagement support

    Support funder-appointed auditors or independent examiners and resolve queries before grant sign-off.

UK grant funders — including National Lottery distributors, UK Research and Innovation, local authorities, and charitable trusts — frequently require independent assurance over how funds were spent. Requirements range from independent examination of project accounts to full statutory audits where charity thresholds are met. Grant agreements specify eligible costs, match funding obligations, outcome reporting, and clawback provisions for non-compliance. We track expenditure against grant budgets in restricted funds, prepare reconciliation schedules linking general ledger postings to funder claim forms, and assemble evidence for compliance audits. Proper grant accounting under the Charities SORP or FRS 102 prevents questioned costs, funding recovery, and reputational damage with public sector and institutional funders.

Common questions

07 / 09

FCA-Regulated Entity Audits

Prepare audit-ready financial statements and regulatory reporting schedules for firms authorised by the Financial Conduct Authority. FCA-regulated entities must meet SYSC requirements for internal controls, client money rules, and capital adequacy — we compile working papers aligned to both ISA (UK) and FCA regulatory reporting obligations.

SYSC internal controls documentation

Client money and asset audits

Capital adequacy reporting

ISA (UK) and FRC standards

How it works, details and FAQs

How it works

  1. 01

    Regulatory scope assessment

    Identify FCA permission types, SYSC applicability, CASS obligations, and reporting requirements for your firm.

  2. 02

    Controls and CASS documentation

    Document internal controls, client money reconciliations, and custody asset records for audit testing.

  3. 03

    Financial statement preparation

    Prepare FRS 102 accounts with regulatory capital note disclosures and FCA annual return reconciliations.

  4. 04

    Dual regulatory and audit support

    Support statutory auditor fieldwork and FCA reporting deadlines concurrently with aligned working papers.

FCA-authorised firms must maintain systems and controls under SYSC rules, comply with Client Assets Sourcebook (CASS) requirements where applicable, and submit audited financial statements as part of regulatory reporting. Statutory audits of FCA-regulated entities follow ISA (UK) standards with additional auditor reporting considerations under the FRC Ethical Standard for public interest entities where applicable. We prepare FRS 102 financial statements reconciled to regulatory capital returns, client money trust account reconciliations, and internal control documentation satisfying SYSC 6 and SYSC 7 requirements. Dual preparation for statutory audit and FCA regulatory review reduces duplication and ensures consistency between audited accounts and the firm's annual regulatory return submitted via RegData.

Common questions

08 / 09

Audit Preparation & Readiness Assessment

Assess your organisation's audit readiness before engaging a statutory auditor — identifying FRS 102 gaps, incomplete reconciliations, and missing PBC schedules that delay fieldwork and increase fees. A structured readiness review reduces surprises during ISA (UK) audit programmes and accelerates Companies House filing timelines.

Pre-engagement gap analysis

Risk area prioritisation

PBC pack pre-assembly

Fee and timeline forecasting

How it works, details and FAQs

How it works

  1. 01

    Current state review

    Analyse trial balance, prior-year audit report, management letter points, and bookkeeping quality.

  2. 02

    Gap identification and scoring

    Compare records against ISA (UK) PBC requirements and FRS 102 disclosure checklist with priority ranking.

  3. 03

    Remediation plan delivery

    Provide actionable fix list with timelines for reconciliations, accruals, disclosures, and supporting evidence.

  4. 04

    Pre-fieldwork sign-off

    Confirm readiness with indexed PBC pack before statutory auditor fieldwork commences.

Audit preparation and readiness assessment identifies gaps in your financial records before a registered auditor begins ISA (UK) fieldwork — the most effective way to control audit cost and timeline. We review adjusted trial balances, bank reconciliations, fixed asset registers, stock counts, revenue cut-off, related-party transactions, and FRS 102 disclosure drafts against a comprehensive PBC checklist. Prior-year audit findings and management letter points are tracked to ensure repeat issues are resolved. Readiness assessments are particularly valuable for first-time audits, companies crossing statutory thresholds, post-acquisition integrations, and businesses transitioning from audit exemption under section 477 to mandatory audit. Remediation completed before engagement reduces scope limitations and qualified opinions.

Common questions

09 / 09

External Auditor Coordination

Serve as your single point of contact for statutory auditor communications — managing PBC requests, fieldwork scheduling, query resolution, and report issuance through to Companies House filing. Proactive auditor coordination minimises business disruption and prevents qualified opinions caused by incomplete responses or missed deadlines.

    Review auditor scope, timeline, fee estimate, and PBC requirements before fieldwork commences.

  2. 02

    PBC fulfilment and tracking

    Manage provided-by-client schedule delivery with status tracking and escalation of overdue items.

  3. 03

    Query resolution during fieldwork

    Respond to auditor inquiries, provide substantiation, and negotiate adjustments before draft report stage.

  4. 04

    Sign-off and filing coordination

    Coordinate audit report signing, board approval, and iXBRL tagging for Companies House submission.

External auditor coordination manages the relationship between your organisation and your FRC-registered statutory auditor throughout the ISA (UK) engagement. We review engagement letters for scope and fee proportionality, maintain PBC request trackers with clear ownership and deadlines, and respond to auditor inquiries with organised evidence packages. During fieldwork we coordinate access to personnel, systems, and documents — resolving testing exceptions before they escalate to audit adjustments. At completion we support management representation letters, subsequent events reviews, and board papers approving the audited accounts. Final coordination includes iXBRL tagging and Companies House filing within the nine-month deadline. Effective liaison typically reduces total audit hours by twenty to thirty percent compared to uncoordinated engagements.
