Message from our Managing Partner
I am proud to report another successful year for Gardiner & Theobald in 2025/26. Our strong commercial performance has allowed us to deepen our investments in what matters most – our people, our digital business platforms, and the communities in which we work.

Managing Partner
Today's markets are defined by complexity and change, and we have adapted quickly. We continue to grow our business by focusing on what we do best – forging enduring relationships with clients and industry peers – while investing in technology and new capabilities that give our people the tools and skills they need, today and in the future.
While the geopolitical environment has grown increasingly fragmented, G&T has moved in the opposite direction, building closer collaboration and unifying our businesses across the UK, US and Ireland. In September 2025, we strengthened the partnership between our UK and US businesses, giving the next generation of US professionals the opportunity to become partners and owners in the firm. In February 2026, we acquired a significant interest in Belfast-based WH Stephens, giving us a strong platform for growth across Northern Ireland and the Republic of Ireland. Working more closely across our markets means we can bring the best of G&T to help solve our clients’ most complex challenges.
Our financial performance has remained resilient. Global revenue increased by 5.2% to £323m, driven by high demand for our expertise and specialist guidance on some of the market’s most innovative and transformational projects.
We approach 2027 with confidence and from a position of strength. While rapid advancements in AI are transforming our sector at unprecedented speed, adaptation has always been core to our profession, and G&T is well placed to capitalise on these shifts. We are also helping to inform the national picture, having been commissioned by the Department for Science, Innovation and Technology to assess the UK’s AI skills labour market.
Our scale gives us access to a wealth of market data from our extensive project portfolio, while our financial stability supports continued investment in technology. At the same time, we remain agile and focused, using technology to refine how we work and enhance the service we provide to clients.
Our financial strength also underpins our commitment to future talent. Our September intake of 84 early talent placements, graduates and apprentices is the largest in the firm’s history.
We remain equally committed to the communities in which we work. This year, we increased our cumulative social value contribution by £4.5m, reaching £28.65m since we began measuring it in 2021, as independently assessed by Thrive.
Disciplined cost and risk management, backed by long-term capital, means that our business remains robust and well positioned for continued growth, both organically and through selective acquisition.
I would like to thank our people for their dedication, and our clients and partners for their continued trust and support. Their contribution underpins our success and gives us every confidence in the year ahead.
