Source: Consultancy 2020-06-24

Ireland’s ten largest consulting firms with an accounting heritage generated more than €2 billion in fees last year, with the Big Four giants making up 86% of all fees. With revenues of over €550 million, on an all-Ireland basis. PwC is Ireland’s largest professional services group that has its roots in the world of accounting. However, today, PwC generates around two thirds of its business outside of its traditional audit division, in services areas including tax advice, mergers & acquisitions, restructuring, management consulting and digital transformation. The number two in Ireland’s accountancy and consultancy market is KPMG, followed by Deloitte and EY. Combined, the so-called Big Four earn nearly €1.8 billion in fee income, generated by a workforce of nearly 15,000 accountants, advisors, consultants and digital specialists. All four of the quartet are privately-held, owned by a group of partners that distribute the firm’s ownership and profits. Aside from the Big Four, the top segment of the Irish accounting and consulting landscape features household names from the global industry. Grant Thornton is number four, ahead of BDO, while Mazars is punching above its weight in comparison to its international size.
