Our Competition Economics team sits within KPMG's global Economics & Regulation Practice.  Together, we combine deep sector knowledge across regulatory & forensic economics, macroeconomics and regulatory finance & accounting.



We are able to tailor the level of our engagement to meet our clients’ needs and resources.


For instance we can:


  • Provide support in the context of competition inquiries, disputes, etc. 
  • Work closely with your team, assisting with carving out and/or reviewing work and analysis as necessary.
  • Set-up and co-ordinate panels of experts to act as a sounding board and quality assessment for work carried out by you.  


We aim to get the right team for you, using the right skills from across KPMG.  We are able to work with you aiming to maximise value.  We are able to offer training and seminars, as well as workshops with KPMG colleagues who can advise on numerous areas.


Our approach is to offer integrated support, whether it be for mergers and acquisitions (including transaction services, corporate finance and monitoring trustee work), regulatory compliance or forensic investigations.
