How we help

Clients look to Byrne Ó Cléirigh to help them identify and exploit opportunities to grow their businesses and develop their facilities. We support investment decision-making by analysing options and conducting risk appraisals for business opportunities, including M&A transactions, new lines of business, reorganisations, expansion and capital investments.


We focus on sustainable business practices as a source of business advantage – how to supply and use energy, how to control environmental impact, and how to manage risk - to help our clients meet the needs of regulators, employees, investors and other stakeholders today and for the future.


We apply our knowledge of systems and processes and our research and analytical skills to identify cost, operational and efficiency improvements, and to set out workable options, with clear recommendations and priorities.
