TC GROUP MARKS STRATEGIC EXPANSION INTO NORTHERN IRELAND WITH GMCG MERGER

TC Group is delighted to announce its expansion into Northern Ireland through a merger with the highly respected accountancy firm GMcG.

GMcG will continue to serve clients from its offices in Belfast, Lisburn and Portadown, maintaining its strong local presence while benefiting from TC Group’s national resources and expertise.

As an Accountancy Age Top 20 firm, TC Group provides bespoke, high-quality accountancy, tax, and business advisory services to a diverse range of clients across the UK. Our proactive and tailored approach ensures that we deliver measurable results designed to help businesses remain compliant, efficient, and profitable, both now and in the future. With over 80 offices across the UK and NI, TC Group is well-resourced to deliver professional, cost-effective, and timely financial solutions to clients wherever they are based.

GMcG has built a distinguished reputation for delivering high-quality accountancy and advisory services to clients throughout Northern Ireland and Ireland. The firm is particularly recognised for its specialist forensic support services to the legal profession. Through the merger, Forensic Accounting will become a new service line for TC Group, enhancing our ability to support clients across the UK and Northern Ireland.

The merger represents not only an exciting step forward but also a continuation of GMcG’s proud legacy of stability, continuity, and excellence. By combining GMcG’s deep-rooted presence and expertise across Northern Ireland with TC Group’s national scale and broader service offering, the Belfast, Lisburn, and Portadown offices are well positioned to deliver even greater value to clients, while preserving the trusted values and traditions that have underpinned the firm’s success for generations.

Whether supporting owner-managed businesses, regional enterprises, or national companies, TC Group remains committed to providing the highest standard of professional service, innovation, and personal attention that clients have come to expect.

Susan Dunlop Lead Partner at GMcG, commented: We are excited to be the first Northern Ireland firm to join TC Group. This is a significant milestone in the evolution of our firm and one that’s based firmly on the knowledge that TC’s shared values, with emphasis on proactive personal service and client care, align seamlessly with our own. Importantly, the shared support, expertise and resources across the Group will allow us to grow and enhance our services, while continuing to operate as the same client focused and locally managed team that our clients have come to know and trust.”

TC Group’s Chief Growth Offcer, Shiv Shah, commented: “We are incredibly proud to welcome GMcG as TC Group’s first partner firm in Northern Ireland.

GMcG is an outstanding business, built over many years through the commitment of its people and the trust of its clients. It is a genuine privilege to have been entrusted with supporting the next chapter of that business under Susan’s and her fellow Partners’ leadership.

What became clear throughout our conversations was how closely our values align. We share a belief that long-term success comes from investing in people, remaining close to clients and preserving the relationships and local leadership that make a firm distinctive.

This partnership is about building on GMcG’s strengths, creating additional opportunities for its people and clients, and supporting the firm’s continued success for many years to come.”
