Financial Due Diligence Services Companies in Aberdeen: Guide to Providers
AC
Acumon Chartered Accountants·12 min read
Choosing a financial due diligence provider in Aberdeen is more than a box-ticking step before a deal. It can shape how clearly buyers, investors, lenders, and business owners understand the financial position behind a transaction.
Aberdeen has a varied advisory market, with firms supporting owner-managed businesses, energy-related companies, property groups, professional services firms, and wider corporate clients. Some providers focus on transaction support and corporate finance, while others offer financial due diligence as part of broader audit, tax, accounting, or business advisory work.
This guide highlights a selection of financial due diligence services companies operating in Aberdeen. Rather than ranking providers, the aim is to give practical context - outlining who these firms are, the types of clients they usually support, and the areas where their due diligence and transaction advisory work may be most relevant.
Acumon
Acumon is a UK firm of chartered accountants and registered auditors providing financial due diligence services as part of its specialist advisory offering. The firm delivers these services across the UK, including Aberdeen, helping buyers and sellers identify and manage risks, validate financial information, negotiate better terms, and make informed pricing and investment decisions.
The firm works with organisations ranging from owner-managed businesses through to larger corporate groups considering acquisitions, disposals, or other transactions. Due diligence engagements draw on the firm’s audit, accounting, and tax expertise, delivering a structured, risk-focused approach.
Acumon provides both buy-side and vendor due diligence. This enables acquirers to assess target companies thoroughly and helps vendors prepare for sale by identifying and addressing issues early. The team operates with agility to meet tight transaction timelines while maintaining depth of analysis. As a growing mid-tier firm with a substantial UK-based team and real-world transaction experience, Acumon combines comprehensive capabilities with responsive service.

Hall Morrice due diligence support appears to sit alongside broader corporate finance advice, so the work is not only about checking historic numbers. It can also connect with cash requirements, funding structure, business modelling, and whether the expected value from a transaction is likely to hold up after completion.

Johnston Carmichael
Johnston Carmichael has a dedicated financial due diligence service within its corporate finance team. The work is built around helping businesses, investors, and acquirers review the financial position of a company before a deal or investment decision is made. Their due diligence process covers financial records, forecasts, tax matters, vendor due diligence, and the risk points that may affect how a transaction is viewed.
Financial due diligence can sit next to transaction tax, business advisory, audit, risk assurance, restructuring, VAT, payroll, and other specialist services. That wider setup can be useful when a deal raises questions beyond the headline financial performance, such as tax exposure, future trading assumptions, or internal controls.
Key Highlights:

Financial due diligence is one of the clearer parts of their service mix, sitting under transaction services alongside buy-side due diligence, sell-side support, vendor due diligence, and red flag reviews.
Quantify Advisors Group also brings financial modelling and vendor assistance into the same advisory frame. That means their work can support both sides of a transaction - buyers looking for a grounded view of a target business, and sellers preparing financial information before a sale process. Their services also cover transaction models, short-term cash flow modelling, working capital work, and diligence preparation support, which gives their due diligence work a practical link to deal planning and negotiation.
Key Highlights:
Focuses on corporate finance and transaction services

The firm works with owner-managed companies, family businesses, UK entities, and international organisations, so its due diligence support is usually connected to bigger business decisions such as acquisitions, sales, fundraising, restructuring, or cross-border growth.
AAB’s corporate finance team brings financial modelling, tax awareness, valuation work, and transaction support into one joined-up service.

Henderson Loggie
Henderson Loggie approaches financial due diligence with a clear focus on lender requirements and transaction readiness. Their work is especially relevant where borrowing is needed to support a sale, acquisition, or change in ownership, since lenders often want an independent view of the business before making a decision.
The firm looks beyond headline figures such as EBITDA, working capital, and cash flow. Henderson Loggie also pays attention to areas that can affect lender confidence, including customer concentration, contract stability, management strength, reporting quality, accounting systems, covenant awareness, and cash discipline. This makes their due diligence support more detailed than a basic financial review, particularly for businesses preparing for lender-instructed checks.
Key Highlights:
Focuses on lender-instructed financial due diligence
Supports business owners preparing for transactions
Covers customer concentration, contracts, and management readiness
Looks at reporting quality, systems, forecasting, and covenant awareness

KPMG’s due diligence work covers assets, liabilities, financial performance, tax matters, and wider deal risks. They also connect due diligence with deal planning, execution, and post-deal integration, which can be important when a transaction depends on more than historic financial results.
Key Highlights:
Provides buy-side and vendor-side due diligence
Due diligence sits within deal advisory services
Reviews assets, liabilities, financial position, and results

Grant Thornton
Grant Thornton focuses its financial due diligence work on acquisition due diligence and transaction advisory. The firm looks at the areas that usually shape an investment decision, including historical trends, business KPIs, underlying earnings, tax risks, working capital, and net cash or debt. Grant Thornton’s work is designed to help buyers understand what is really sitting behind the financial picture before they move further into a transaction.
A clear part of Grant Thornton’s approach is the focus on underlying profitability. They review one-off or unusual items, trading dynamics, and debt-like items that may affect deal value or negotiations.

Conclusion
Choosing a financial due diligence provider usually starts with the type of transaction on the table. A buyer may need a close review of earnings, working capital, debt-like items, cash flow, and forecast assumptions. A seller may need vendor due diligence or vendor assistance before going to market. Lenders and investors may look for a different level of detail, especially where borrowing, covenant risk, or customer concentration is part of the decision. This guide is not intended to rank financial due diligence services companies in Aberdeen. Its purpose is to give a clearer starting point for comparing providers, understanding their areas of focus, and deciding which firms may be worth a closer look for a specific transaction.
