Duncan & Toplis, which celebrates its 100th anniversary in 2025, is on course for the biggest period of growth in its history after securing private equity investment in 2023. The company’s ambitious strategy is primarily focused on strong organic growth, supplemented by a number of highly strategic acquisitions that broaden the service offering to clients and expand the business geographically into new key locations. 

This strategic move will see Haines Watts North London rebranded as Duncan & Toplis, with all team members remaining in their roles. Amilios Costa, Managing Partner, will continue to lead the team in this exciting next phase of their growth journey.
