D2 is now TSA Riley
19 July 2026
This milestone brings together D2's specialist expertise in infrastructure delivery with TSA Riley's property capabilities under one unified brand. It reflects our vision of building a stronger global organisation - one that combines complementary capabilities and delivers even greater value for clients, while retaining the collaborative, people-focused culture that has underpinned D2’s success.
For existing D2 clients, it’s business as usual. You’ll continue working with the same trusted people and teams, with your service quality, project delivery, and established relationships remaining our highest priorities. At the same time, clients will benefit from enhanced resources, broader multidisciplinary expertise, and access to TSA Riley's global network.
The transition also creates new opportunities for our people. As one global brand, we can offer broader career pathways, greater project exposure, and access to a wider network of expertise, while preserving the technical excellence and client-focused approach that have always distinguished D2.
“D2 has established an exceptional reputation for helping clients successfully deliver major projects and programmes. Bringing D2 fully into the TSA Riley brand is a natural next step in our journey together. It creates a stronger global platform for our clients and our people, combining our capabilities, expanding our reach, and providing a clearer, more integrated offering to the market. Importantly, it allows us to retain the trusted relationships, collaborative culture, and specialist expertise that clients value while enhancing the resources and support available to them.”—David Innis, UK, Ireland and Canada Managing Director of TSA Riley
As one TSA Riley team, we look forward to supporting clients with the scale, expertise, and global perspective needed to deliver successful projects and create lasting value.
