What Imagile Professional Services does

Semperian Group Limited is a privately held UK infrastructure investment manager specializing in mature Public Private Partnership (PPP) and social infrastructure concessions, launched in October 2007 with the acquisition of a £1.0 billion portfolio from Land Securities plc. The firm's origins trace back to 2001 through the Secondary Market Infrastructure Fund Facility (SMIFF), created by Abbey National and Babcock & Brown as the first UK PFI secondary market transaction. Today Semperian manages a diversified portfolio of 97 PPP assets across the United Kingdom and the Republic of Ireland, spanning toll roads, hospitals, prisons, energy-from-waste facilities, student accommodation, and other public infrastructure. The company serves institutional investors seeking predictable, RPI-correlated, long-dated returns uncorrelated to broader economic cycles.

The business operates through a two-tier governance structure: a Board of Directors (Chair, four Executive Directors including CEO, COO, CIO, CFO, plus Non-Executive and Independent Non-Executive Directors) responsible for strategy, oversight, and compliance; and the fully integrated Semperian Management Group, a wholly owned subsidiary that encapsulates all capital and asset management activities for the underlying portfolio. Semperian pursues a programmatic secondary-market acquisition strategy, regularly purchasing incremental stakes from construction contractors and other co-investors (e.g., Balfour Beatty, HICL, Sodexo, Impregilo) to consolidate positions in existing assets. The firm is supported by a £75 million revolving credit facility established in 2018 to smooth equity raises and support new investments.

The revenue model is managed services for institutional investors, with returns generated through ownership of inflation-linked PPP concession assets rather than transactional fees. Pricing is not publicly disclosed; terms are negotiated bilaterally with institutional limited partners. The firm exited direct facilities management operations in 2011 via the sale of PIML to Compass Group, refocusing on pure investment management. In 2025, Semperian PPP Investment Partners rebranded to Semperian Group to align the corporate identity with its integrated management platform.

Direct peers

• BBGI Global Infrastructure: London-listed PPP infrastructure investment company holding a diversified portfolio of operational social and economic infrastructure concessions — directly comparable in mandate and asset class.
• HICL Infrastructure Company: UK-listed investment company focused on PPP/PFI infrastructure assets. Already involved in transactions with Semperian (notably the Fife Hospital stake sale). Most direct comparable in the UK PPP secondary market.
• Equitix: UK-based investment manager and primary developer of PPP/PFI concessions with a focus on social infrastructure (health, education, emergency services). Closely comparable in scale and asset focus.
• 3i Infrastructure: Listed infrastructure investment company with material PPP/PFI exposure. Operates in the same UK/European social infrastructure market with a comparable long-dated yield-driven strategy.
• John Laing Group: UK-listed pure-play PPP infrastructure investor and asset manager with a portfolio of greenfield and operational PPP concessions, providing a closely comparable business model and asset class.
• Dalmore Capital: UK-based investment manager specialising in PPP/PFI secondary market transactions. Directly comparable given its focus on acquiring mature UK PPP concession portfolios from banks and original developers.

Broad incumbents

• InfraRed Capital Partners: Larger global infrastructure investment manager (part of Nuveen/Schroders-adjacent ownership) with a significant PPP and social infrastructure portfolio. Overlaps with Semperian in the UK concession market but operates at significantly broader global scale.
• Macquarie Asset Management: One of the world's largest infrastructure asset managers with extensive PPP/PFI exposure. Serves institutional investors with infrastructure mandates similar to Semperian's value proposition but at vastly greater AUM scale.
• GIP (Global Infrastructure Partners, now BlackRock): Major institutional infrastructure investment manager (now part of BlackRock) with global greenfield and operational PPP exposure. Provides the institutional fund-raising template Semperian could emulate at scale.
