Trustmarque Group and Ultima Business Solutions have completed their long-anticipated merger, forming what the companies describe as a “new technology powerhouse” for the UK IT services market.

The newly unified group will now begin an integration process led by Trustmarque’s Simon Williams as chief executive officer and Ultima’s Jamie Beaumont as chief financial officer. The merger brings together two very established IT services firms, combining nearly four decades of industry experience across public and private sectors.

Together, the group now employs more than 1,000 people across seven global locations, including York, Reading, London, Glasgow, Dubai, Singapore, and the United States. It serves more than 3,000 customers and is targeting gross invoiced income growth to exceed £1 billion, reinforcing its position as one of the largest IT channel players in the UK.

“This completion marks the beginning of a new chapter – from today we are stronger together, built on innovation, scale, and expertise,” said Simon Williams, CEO of the new group.

“By combining Ultima’s automation and managed services strength with Trustmarque’s deep technical heritage and professional services expertise, we are uniquely positioned to help our customers cut through that complexity to unlock tangible value today and in the future.

“IT leaders are telling us their estates have become more complex, and that creates real barriers to maximising innovation and growth. Responding to this demand requires partners remain attuned to these shifts and adapt with the right expertise.”

Founded in 1987, York-headquartered Trustmarque has built a reputation as a key technology services partner with more than 550 employees. Reading-based managed services provider Ultima, established in 1990, brings over 450 staff to the combined group.

For the time being, both businesses will continue operating under their existing brands, though a new corporate identity is expected to launch later next year. The company said it will leverage its combined scale and resources to deliver “smarter, more integrated” IT services, with a particular focus on helping customers simplify complex digital estates.

Jamie Beaumont, CFO of the merged group, added: “We’re already seeing new joint opportunities emerge from enabling multi-cloud optimisation to delivering next-gen AI-powered operations for clients across sectors. Our integration teams have laid the groundwork for a seamless transition, and we are excited to move forward as one team with one mission: to help our clients thrive in a fast-changing digital world.”

The merger comes at a time when enterprises are grappling with increased complexity in their IT environments – a challenge that is slowing adoption of technologies such as AI, cloud automation, and digital transformation tools. The new group said it intends to address these pressures through integrated service delivery, drawing on its shared technical and operational expertise.

Trustmarque and Ultima also bring extensive relationships with major technology vendors, including Microsoft, Cisco, IBM, HPE, Hitachi Vantara, Palo Alto, and Citrix. The combined scale, they said, will enhance buying power and strengthen collaboration across the vendor ecosystem.
