Turnover rose to £50.1 million, up from £43.9m, for the year ending 31 May 2025, marking a 14 per cent increase. The firm continued to grow its national footprint, with standout progress in Glasgow, where the office has rapidly scaled from a small base to nearly 50 people, with revenues increasing at close to 50 per cent year on year.

As it continued to expand its national footprint, Thorntons capitalised on the recovery in the property market, delivering a 24 per cent increase in associated revenue alongside a robust pipeline of corporate deal flow, private client work and international referrals. The firm also delivered strong growth in sectors critical to the Scottish economy such as energy, healthcare, tech and agriculture.

Operating profit held steady at £11.6m (£11.8m). This reflects Thorntons’ strategic investment during the year in its office locations, technology and people, setting up the firm for sustainable future growth.

This momentum underpins the firm’s decision to relocate its headquarters to James Thomson House, a flagship £26m waterfront development by Dundee City Council. Thorntons will occupy the top three floors of the Grade A building, reaffirming its long‑term commitment to Dundee, where it was founded.

The new HQ will provide modern workspaces, high-spec client areas, collaboration and event spaces and cutting-edge digital infrastructure. Designed to the highest sustainability standards, it includes BREEAM Excellent and EPC A credentials, alongside facilities supporting active travel.

Managing partner, Lesley Larg, said: “This is a seismic moment for Thorntons. In the past year we have expanded into new markets, welcomed exceptional talent and delivered sustained revenue growth across our full-service offering.

“Our growth across Scotland, combined with our new headquarters in the heart of Dundee, reflects our long-term confidence in the city and in the future of our firm. Dundee is our home and it will remain so. We want Dundee to benefit from the wider success of Thorntons. Our new HQ gives us a modern base to attract talent, embrace innovation and deliver even more for individual and business clients across the country.”

Councillor Mark Flynn, leader of Dundee City Council, said: “Thorntons is a home-grown success story. The firm has expanded significantly in recent years and remains proud of its heritage. The new premises will enable it to progress its ambitions, especially around emerging technologies.”
