    How we can help


Your shareholders and stakeholders want to feel confident; you need insights and advice to help you sleep easy. Besides providing honest facts and transparency, we go further – helping ensure your regulatory compliance and guiding your strategies to grow and sustain your business.  

By getting under the skin of your organisation, we’ll help you gain a clearer understanding of your risks and potential, with proactive suggestions for improving performance. 


AI and associated tech tools are invaluable, but there’s no substitute for experienced interpretation. Our experts bring a wide array of appropriate skills and relevant knowledge. 

We’ll adapt to suit you – for example, assisting your in-house team on an internal audit, providing long or short term secondments or a specialist team for your joint venture audit.  

Organisations face increasing pressure and despite the best intentions, mistakes can be made. So pre-empt them with your own checks. We offer anti-fraud solutions, a safe whistleblowing environment and of course, you can absolutely depend on our clarity, honesty and integrity.  


Your statutory external audit is just the baseline; we provide real value by drilling deep into your business, speaking to Partners and senior staff and understanding your culture. As well as the factual content, our objective, timely health check will help advance your plans for progress. 

We team up with Crowe Global (through Accelerate) and TIAG (The International Accounting Group) to offer a seamless international audit service, with AAB acting as the single point of contact. We’ll coordinate your audit to satisfy both the UK statutory requirements and your group auditor’s reporting needs. 


The more you grow, the greater the risks and your responsibility to shareholders and stakeholders. Our multi-route approach to internal auditing helps you plan effectively and meet financial, strategic and ESG targets more easily. 

  • Internal Audit Projects – identifying and addressing specific or emerging risks. 
  • Co-sourced Internal Audit Services – we provide specialist expertise, you retain control.  
  • Outsourced Internal Audit Services – organising a risk-based audit and reporting on your governance and controls.  
  • Risk Management Services – helping you develop effective policies and procedures to mitigate and eliminate risk.  
  • Contract Health Check – ensuring your key contracts operate or providing a pre-contract audit review. 
  • Forensic Contract Audit – a detailed review of suppliers to ensure compliance. 
  • Forensic Investigations – our experts check for fraud and help eliminate weak spots.
