London, United Kingdom, March 4, 2025. Scotland-based engineering consultancy RSP Consulting Engineers LLP will become part of the construction and real estate consulting firm Drees & Sommer UK, which will hold 100 percent of the shares of the acquired company.  

The acquisition became legally effective on 3 March 2025. Established in 1987, RSP has developed into one of the foremost design engineering consultancies in the UK. The firm is known for its work within the Financial Institutions, Hospitality, Data Centres, and Life Sciences sectors, as well as its commitment to providing economical and environmentally sustainable design solutions.

RSP's areas of expertise, which include building services design, energy optimisation, and infrastructure, enable Drees & Sommer to deliver a complete interdisciplinary approach within the UK. This latest strategic acquisition by Drees & Sommer UK follows the recent acquisition of Johnston Houston, a top building and construction consultancy based in Northern Ireland, in September 2024.

The addition of RSP Consulting Engineers brings in excess of 60 new employees to the Drees & Sommer UK team, increasing the total workforce to over 300 employees across 12 offices in the UK. This expansion underscores the company's ambitious growth strategy and commitment to enhancing their market presence and service offerings across the UK and Ireland.

RSP will continue to develop its portfolio as "RSP Consulting Engineers - Part of Drees & Sommer" under the leadership of the current management team, before officially rebranding to Drees & Sommer at some point in the future.

Steffen Szeidl, Spokesman of the Board at Drees & Sommer, highlighted the strategic benefits of the merger: “Joining forces with RSP represents a significant leap forward in our ability to serve the UK market. RSP's distinguished track record in engineering excellence perfectly aligns with our vision of sustainable and forward-thinking solutions. This merger not only broadens our service capabilities but also enhances our geographical reach, particularly in Scotland. We are confident that this partnership will drive substantial growth and innovation, benefiting our clients and the industry.”

Kenneth Wood, Managing Director of the UK and Partner at Drees & Sommer, expressed his enthusiasm for the merger: “The acquisition of RSP is a transformative step for Drees & Sommer in the UK. This merger not only strengthens our market position but also significantly enhances our service offerings. RSP's unparalleled expertise in design engineering and strength in complementary sectors such as Data Centres and Life Sciences, combined with our extensive experience in sustainability and real estate, creates a unique synergy that will drive innovation and excellence. We are excited to welcome RSP to the Drees & Sommer family and look forward to achieving new heights together. This partnership is a testament to our commitment to delivering exceptional value and sustainable solutions to our clients.”
