    How we can help


As international governments and public perception moves towards more sustainable, lower carbon power generation and industries, the energy sector is experiencing a significant and rapid transition.   

With in-depth energy sector knowledge that’s both well-established and fully up to speed, we are uniquely able to advise you and help guide your projects. Whether you’re involved in hydrocarbons production or the latest renewables technology, we’ll use our expertise to provide practical advice that understands the volatility, operating challenges and high expectations of the energy sector.  

We understand the business risks and will work with you to develop plans that mitigate those risks, capitalise on opportunities and create competitive advantage.  


Energy transition has been taking place for centuries. Society has moved from being reliant on wood, to coal to hydrocarbons as principal sources of energy and the transition is constantly evolving.  

Today, with greater global emphasis on working towards and meeting net-zero greenhouse gas emissions targets, there’s never been a greater impetus to reduce and manage our global CO2 footprint across all industries in the energy sector.  

Our experienced team works with companies, strategic bodies, agencies and organisations in the private and public sectors to develop strategies, models and funding requirements that address change and energy transition. 

We work with renewable energy companies who have established themselves in the sector and with more traditional energy companies growing their products and services into renewables.  Here, amongst other services, we deliver advice relating to R&D tax relief, fundraising, growth and M&A. 


The renewables and clean energy sectors have developed significantly, with recent changes in policy and public perception driving towards a more sustainable and greener industry. We have seen considerable growth internationally, for example in offshore wind farms on the East Coast of America, Taiwan, Germany and the UK.   

Throughout these changes, our team at AAB has continually developed our invaluable expertise in renewables and clean energy industries, including wind, hydrogen, hydroelectric, geothermal and solar.     

We help energy and power businesses get ahead and stay ahead in the transitioning world of renewables and clean power. Our services support businesses in transforming their operations, developing future strategies and delivering efficiencies.  

AAB’s approach to be your trusted advisor allows you to focus on running and developing your business whilst we take care of your finance and HR through our Virtual Finance Function and HR services. We will also work alongside you in partnership to help you achieve your business goals, whether that be fundraising, M&A or consulting support. 


The transition from hydrocarbons cannot happen overnight, and so our specialist upstream exploration and production team continues to support businesses in this sector. From our Aberdeen and London offices, our team of experts and technical specialists, with backgrounds in accounting, tax, industry and professional services, will work with you to deliver full lifecycle support.   

Our services include accounting, tax, audit, joint venture, drilling & contract audit, corporate finance, payroll and consulting. 

With an extensive client base and industry network spanning across six continents, we deliver finance and HR outsourced services and project-based work. We offer up-to-date hands-on experience and tried and tested methodologies in many aspects of North Sea and international upstream transaction and transition support, integration and programme management.  


Energy services companies that provide assets, maintain facilities and train, develop and provide personnel, in the UK and globally, are now facing extra challenges. In addition to strict reporting deadlines and complex contracts across a variety of jurisdictions, they are now adapting from their traditional operating base to serve new clients in the renewables and clean energy sector.  

We can help your business adapt to new demands. Our experienced, specialist team can project manage your evolving accounting and business requirements from start to successful conclusion. We’ll support you with assurance and advisory, tax compliance, corporate finance and other business support services.  

Across our all areas of the energy services sector, from offshore wind to oilfields, solar farms to hydropower, we will become your trusted partner, providing outsourced finance and HR solutions to help you operate efficiently and cost-effectively, with the knowledge you are fully compliant and working with a team that put your ambitions first. 


  • As a smaller sized business, it is a comfort to know that our payroll is being taken care of by the experts and we can concentrate on supporting other areas of our business.

  • AAB proactively assisted in addressing any potential risk areas relating to Corporate Criminal Offence legislation in our business and ensured a successful solution was implemented in conjunction with our legal, tax and finance teams.

  • AAB took over as Applus+ UK’s external auditor in 2022. The difference we have noticed compared to other auditors is that AAB Audits like we manage our business, adapting its procedures to our systems and the specifics of how Applus+ UK operates.
