How to Prepare for a Grant Audit: Compliance Guide

Partner & Head of Grant Audits

Last reviewed: 20 July 2026

Preparing for a grant audit should not begin when an audit notification arrives.

In our experience, organisations that achieve the best audit outcomes are those that build compliance into project delivery from the outset. By maintaining accurate records and understanding funding requirements throughout the project lifecycle, audit preparation becomes significantly easier.

Whether you have received funding through a public sector body, innovation programme, research grant, or regional development scheme, being prepared for audit can help protect funding and reduce compliance risks.

This guide explains how to prepare for a grant audit, and the practical steps organisations can take to improve audit readiness.

What Is a Grant Audit?

A grant audit is an independent review designed to verify that grant funding has been used correctly and in accordance with the funding agreement.

Auditors typically seek to confirm:

Grant claims are accurate

Expenditure is eligible

Documentation is complete

Project activity aligns with agreed objectives

Funding conditions have been met

The aim is to provide assurance that public funds have been used appropriately.

Why Grant Audit Preparation Matters

Effective preparation can reduce disruption, minimise audit findings and improve confidence in project controls.

When speaking to clients, we often find that audit preparation is viewed as an activity that takes place near the end of a project. However, the strongest audit outcomes are usually achieved where compliance processes have been embedded from the beginning.

Good preparation can help organisations:

Protect funding awards

Reduce administrative burden

Improve internal controls

Respond quickly to audit requests

Avoid costly compliance issues

What Documents Do Grant Auditors Typically Review?

Although requirements vary between programmes, auditors commonly review:

Funding agreements

Grant claim submissions

Project budgets

Supplier invoices

Contracts

Bank payment evidence

Payroll records

Timesheets

Procurement documentation

Progress reports

Approval records

A useful question to ask is whether an independent reviewer could understand and verify a transaction using the documentation available.

How to Prepare for a Grant Audit

Step 1: Review the Funding Agreement

The funding agreement should be your starting point.

Pay particular attention to:

Eligible expenditure

Ineligible expenditure

Procurement requirements

Claim deadlines

Reporting obligations

Record retention requirements

In our experience, many audit findings originate from misunderstandings about funding rules rather than intentional non-compliance.

Step 2: Confirm All Costs Are Eligible

Before submitting claims, verify that all expenditure complies with the funding conditions.

Review:

Project relevance

Budget approvals

Timing of expenditure

Cost categories

Funding restrictions

Any uncertainty should be clarified before costs are claimed.

Step 3: Gather Supporting Evidence

Every claim should be supported by complete documentation.

Typical evidence includes:

Invoices

Purchase orders

Contracts

Payment confirmations

Payroll records

Timesheets

Procurement records

Missing evidence is one of the most common causes of audit adjustments.

Step 4: Review Staff Cost Calculations

Staff costs often represent a significant element of grant claims.

Review:

Salary calculations

Timesheets

Project allocations

Employer cost calculations

Approval processes

We regularly see otherwise eligible staff costs challenged because supporting calculations cannot be readily demonstrated.

Step 5: Test Your Audit Trail

Auditors need to trace expenditure from claim submission back to supporting evidence.

Ask:

Can every claimed cost be located quickly?

Are records stored consistently?

Are approvals documented?

Can expenditure be linked to project activity?

Strong audit trails significantly improve audit efficiency.

Step 6: Review Procurement Compliance

Procurement records should demonstrate that supplier selection processes met funding requirements.

Ensure you retain:

Quotations

Tender documents

Evaluation records

Supplier approvals

Justifications for supplier choice

This area is frequently reviewed during grant audits.

Step 7: Conduct an Internal Compliance Review

Before a formal audit takes place, perform an internal review.

Consider:

Eligibility compliance

Documentation completeness

Payroll calculations

Procurement compliance

Claim accuracy

Internal reviews can identify weaknesses before external auditors do.

Grant Audit Preparation Checklist

Before an audit, confirm you have:

Funding agreement

Approved project budget

Grant claim submissions

Supplier invoices

Evidence of payment

Contracts and agreements

Payroll records

Timesheets

Procurement documentation

Project reports

Approval records

Cost allocation methodologies

Record retention procedures

Common Problems Identified During Audit Preparation

When carrying out audit readiness reviews, we commonly identify:

Missing supplier documentation

Incomplete timesheets

Weak audit trails

Procurement gaps

Unsupported cost allocations

Costs outside approved project dates

Identifying these issues early gives organisations an opportunity to address deficiencies before a formal audit takes place. Read our full guide on Common Grant Audit Failures.

How Organisations Can Improve Audit Readiness

Strong audit readiness is built through process rather than last-minute preparation.

Best practice includes:

Assigning compliance responsibilities

Training project teams

Centralising document storage

Conducting periodic internal reviews

Monitoring claims regularly

Reviewing funding requirements throughout the project

In our experience, organisations with clear procedures and ownership of compliance responsibilities generally experience smoother audits.

When Should You Seek Professional Advice?

Professional support may be valuable when:

Preparing for a significant audit

Managing complex funding programmes

Responding to compliance concerns

Implementing new controls

Reviewing historic claims

We often support organisations through independent audit readiness reviews, helping identify potential compliance gaps before funder audits occur.

Conclusion

Successful grant audits rarely happen by accident.

They are normally the result of good planning, strong documentation and a clear understanding of funding requirements throughout the life of a project.

In our experience, organisations that build audit preparation into day-to-day project management are better placed to demonstrate compliance, protect funding and reduce the risk of unexpected audit findings. By maintaining a robust audit trail, monitoring expenditure carefully and reviewing claims before submission, organisations can approach audits with greater confidence.
