Grant Thornton Ireland is one of the country's largest professional services firms, providing advisory, audit and tax services to clients of all sizes across industries. Its client base spans privately owned businesses, publicly listed companies and the public sector. The firm employs nearly 3,000 professionals in Ireland and is a member firm of Grant Thornton International, a network of approximately 80,000 people operating across more than 150 markets.
Service delivery is organised around three core areas. Advisory covers business challenges for privately owned, publicly listed and public sector clients. Audit provides audit and assurance services to clients of all sizes across industries, and Tax covers tax services across the same breadth of clients. Technical work sits within these domains: audit and assurance, tax services, advisory services and professional services more broadly.
The firm operates from eight locations: Dublin, Belfast, Cork, Galway, Limerick, the Isle of Man, Gibraltar and Bermuda. Its stated approach pairs local knowledge and national expertise with the reach of the global network, and emphasises long-term client relationships, with partners and teams investing time to understand clients' businesses. The firm describes its model as a different way of working, with an emphasis on innovative service delivery and high standards.
