HCA is one of Belfast's leading firms of Chartered Accountants and Business Advisers, combining world-class technical expertise with the personal attention our clients deserve — and rarely find elsewhere.

HCA was established in 2013 with a clear conviction: that the very best advisory could be delivered to local, national and international businesses through a practice built entirely on the depth of its people — their experience, their expertise and their personal investment in every client's success.
Founded by John Hannaway, and built by a team of partners whose combined careers span the profession's most demanding disciplines, HCA has grown into one of Belfast's leading firms of Chartered Accountants and Business Advisers. The firm's commitment has never wavered: excellent advice, from exceptional people, who care deeply about the outcome.
Based at The Gasworks in Belfast, HCA today serves owner-managed businesses, growing companies and high net worth individuals across Northern Ireland and beyond. We are proud of our team, our place, our clients and most importantly, the quality of service we provide to each of them.
These four words are not marketing. They are the standard we hold ourselves to with every client, on every piece of work, every single day. They are the foundation on which HCA was built, and they remain the measure of everything we do.
Qualified, rigorous and held to the highest standards of our profession. Our partners hold some of the most respected designations in accountancy and tax.
Advice you can actually use — clear, actionable and tailored to your specific situation. We don't deal in theory. We deal in results.
We genuinely care about your business and its success. The difference between good and great advice is usually the depth of commitment behind it.
You deal directly with our partners and senior staff. We know your name, we know your business, and we treat every client relationship as a long-term one.
As a member of Russell Bedford International, HCA is part of one of the world's leading networks of independent professional services firms — present in more than 100 countries with over 600 offices worldwide.
This means our clients benefit from trusted, local advisers in any market they operate in — whether that's managing international tax structures, completing cross-border transactions or supporting expansion into new territories.
We are proud to bring Northern Ireland's businesses to the world — and to ensure that international businesses operating in Northern Ireland receive the same quality of advice we deliver at home.
