Most dental practice owners assume they need an audit every year, but this isn't always the case. The statutory audit requirement depends on your practice's size and structure, not whether you treat NHS or private patients.
Getting this wrong can mean paying for unnecessary audits or, worse, failing to comply with legal requirements. Here's what you need to know about audit requirements for UK dental practices.
What is a Statutory Audit?
A statutory audit is an independent examination of your practice's financial statements, required by law for certain companies. It's different from the routine accounting work that prepares your annual accounts.
The auditor must be qualified and independent. They review your financial records, test transactions, and provide an opinion on whether your accounts show a "true and fair view" of the practice's financial position.
This process typically costs £3,000-£8,000 for a dental practice, depending on size and complexity.
Companies Act Audit Thresholds
Under the Companies Act, your dental practice needs a statutory audit if it exceeds at least two of these thresholds:
- Annual turnover: £10.2 million
- Balance sheet total: £5.1 million
- Average employees: 50
These are the thresholds for the 2024 financial year. They're reviewed periodically, so the figures may change in future years.
For most single-site dental practices, these thresholds are well above typical operating levels. A busy mixed practice might have turnover of £1-2 million, which is nowhere near the audit threshold.
When Dental Practices Do Need Audits
Several situations can trigger an audit requirement for dental practices:
Large Multi-Site Groups
Corporate dental groups with multiple locations often exceed the turnover threshold. A group operating 8-10 practices could easily reach £10+ million annual turnover.
These groups typically have substantial assets too — property, equipment, and goodwill — which can push them over the balance sheet threshold.
Shareholder Requirements
Even if you're below the statutory thresholds, shareholders holding 10% or more of the company can request an audit. This sometimes happens in dental partnerships where one partner wants additional assurance over the financial statements.
The request must be made in writing, and you'll need to arrange an audit for that year.
Lender Requirements
Banks and finance providers sometimes require audited accounts as part of loan agreements. This is more common for larger practices or when borrowing significant amounts for practice acquisitions.
Check your loan agreements carefully — the requirement might kick in at certain borrowing levels or asset values.
Audit Exemptions for Small Companies
Most dental practices qualify as "small companies" under the Companies Act and are exempt from audit requirements. To qualify for small company exemption, you must meet at least two of these criteria:
- Annual turnover: £10.2 million or less
- Balance sheet total: £5.1 million or less
- Average employees: 50 or fewer
Note these are the same figures as the audit thresholds — if you're below two of the three limits, you're typically exempt from audit.
Small company exemption means you can file abbreviated accounts at Companies House and don't need an independent audit of your financial statements.
Partnership vs Limited Company Structure
Your practice structure affects audit requirements significantly:
Traditional Partnerships
Dental partnerships aren't companies, so Companies Act audit rules don't apply. Partners are personally liable for the business, and there's no requirement for independent audit of partnership accounts.
However, you might still choose an audit for other reasons — lender requirements, partnership agreement terms, or additional assurance for complex arrangements.
Limited Companies
Incorporated dental practices must comply with Companies Act requirements. This includes the audit thresholds discussed above.
Many dental practices incorporate for tax efficiency, but this brings additional compliance obligations including potential audit requirements.
Alternatives to Statutory Audit
If you don't need a statutory audit, you still have options for independent review of your accounts:
Independent Examination
An independent examiner reviews your accounts but provides limited assurance compared to a full audit. It's cheaper (typically £1,000-£2,500) and less intrusive than an audit.
This can be useful if lenders or partners want some independent oversight without the full cost of an audit.
Agreed-Upon Procedures
You can engage an accountant to perform specific checks on particular aspects of your financial statements. This might focus on revenue recognition, expense classification, or specific transactions.
It's more targeted than an audit and can address specific concerns without the comprehensive review that a full audit requires.
Planning for Audit Requirements
If your practice is approaching the audit thresholds, start planning early:
Monitor your metrics: Track turnover, balance sheet total, and employee numbers throughout the year. Don't wait until year-end to discover you need an audit.
Choose your auditor carefully: Find an audit firm with dental sector experience. They'll understand the specific issues in dental practices — from NHS contract accounting to private treatment plans.
Prepare your records: Auditors need detailed records and supporting documentation. Poor record-keeping makes audits more expensive and time-consuming.
Consider timing too — audit firms are busiest in spring when most companies have December year-ends. If you have a choice of year-end date, this might influence your decision.
Cost-Benefit Analysis
Before arranging a voluntary audit, weigh the costs against the benefits:
Costs include: Audit fees, management time, potential disruption to the practice, and ongoing compliance obligations.
Benefits might include: Enhanced credibility with lenders, improved internal controls, independent verification of financial performance, and potential identification of errors or inefficiencies.
For most small dental practices, the costs typically outweigh the benefits unless there's a specific requirement from lenders or shareholders.
Getting Professional Advice
Audit requirements can be complex, particularly for growing practices or those with unusual structures. The thresholds change periodically, and there can be specific exemptions or requirements based on your circumstances.
A specialist dental accountant can help you understand your obligations and plan for any upcoming requirements. They can also help structure your practice to minimize unnecessary compliance costs while meeting your legal obligations.
If you're considering different ways to extract profits from your practice, this might affect your audit requirements depending on the structure you choose.
