How to Prepare for a Valuation Audit

Why Valuation Audits Matter

Whether you’re selling your business, raising investment, or planning a transition, a professional valuation may be audited by external parties — such as investors, acquirers, HMRC, or internal stakeholders. Being well prepared for a valuation audit not only helps you avoid delays or scrutiny, but also ensures you maintain credibility and maximise your business’s perceived value.

1. Organise Your Financial Information

Auditors will want to see:

• Three years of financial statements

• Tax returns (corporation tax, VAT, PAYE)

• Management accounts and forecasts

• A clean trial balance and reconciliations

• Supporting documents for one-off adjustments

Ensuring this is clearly presented and up to date will speed up the process and reduce the number of follow-up queries.

2. Prepare Key Business Documentation

Supporting records are essential in validating your valuation inputs. Gather:

• A full list of tangible and intangible assets

• Copies of customer contracts and supplier agreements

• Shareholder information and ownership structure

• Legal documents (leases, insurance, IP ownership)

• Staff structure, payroll, and bonus schemes

Well-organised documentation demonstrates control and transparency.

3. Clarify the Purpose and Basis of the Valuation

Different scenarios require different valuation approaches. Make sure the valuation report clearly outlines:

• The purpose (e.g. sale, EOT transition, share buyback, tax planning)

• The valuation date

• The chosen methodology (e.g. earnings multiple, DCF, net assets)

• Any material assumptions

Discuss these in advance with your adviser to ensure alignment with the intended use of the valuation.

4. Explain Forecasts and Assumptions

If your valuation is forward-looking, ensure forecasts are supported by:

• Realistic growth assumptions

• Sector and market data

• Evidence of pipeline, contracts, or order book

• Notes on seasonal or one-off variations

A valuation based on overly ambitious or undocumented forecasts may be challenged during audit.

5. Identify and Reduce Owner Dependency

Auditors (and buyers) often question how much of the business depends on the current owner. If you can show that operations, client relationships, and decision-making are spread across a team — or backed by documented systems — this increases perceived value and stability.

6. Conduct an Internal Review

Before submitting your valuation for audit, perform a basic internal review:

• Cross-check data with your accountant

• Flag any inconsistencies or unusual adjustments

• Prepare short written explanations for potential queries

A pre-audit review helps identify issues early and avoids last-minute scrambling.

7. Work with a Qualified Valuation Adviser

The right adviser can:

• Help you prepare thoroughly

• Defend your valuation method under scrutiny

• Handle queries from auditors or regulators professionally
