What Keltbray Infrastructure Services does

Keltbray Infrastructure Services is a UK-based specialist engineering and construction services provider founded in 1976 and headquartered in Thames Ditton, Surrey. The company operates an integrated self-delivery model spanning demolition, piling, ground engineering, remediation, structures, asbestos removal, rail services, energy infrastructure, and decommissioning, serving commercial property developers (Great Portland Estates, Stanhope, Landsec, Mitsubishi Estate, Sellar), government infrastructure clients (HS2 Ltd, Transport for London, NHS, Sheffield County Council), energy companies (Scottish Power Energy Networks, SSE), and rail operators. The Group has completed over 2,000 projects since inception and employs approximately 1,500 people across the UK plus Northern Ireland.

The company's technology stack includes the patented HIPER® Pile foundation system (Hollow, Impression, Precast, Energy-generating, and Reusable), which reduces concrete volume by 41% and embodied carbon by 35% versus traditional bored piles and won the ICE London Brunel Medal in 2025. Operational technology includes the Keltbray Integrated Piling System (KIPS) for live concrete process management, digital construction management tools deployed on projects like HS2 Curzon Street for real-time progress tracking, and the FLEX internal learning and development platform. AI-enabled digital automation supports back-office processing of Goods Received Notes and supplier invoices. The Hiperpile subsidiary is positioned as the vehicle for international commercialisation of the patented foundation system.

Keltbray generates revenue through project-based contracts sold via direct enterprise sales to developers and government agencies and via subcontracting to main contractors (Mace, Costain-Skanska JV, Mace-Dragados JV, Riverlinx CJV) on major infrastructure projects. The business is privately held, majority-owned by Executive Chairman Brendan Kerr, with Ryan Kerr as Executive Director representing the family legacy; Peter Burnside was appointed Group CEO in June 2026. As of FY2025 (year ended October 2025), Keltbray reported underlying pre-tax profit of £5.3 million (up from £3.2 million in FY2024), period-end cash of £11.4 million, net assets of £30.3 million, and a £244 million order book. Following the 2024 divestment of the Group's Infrastructure business, the company expects revenues to exceed £400 million by 2027, supported by expansion into National Infrastructure, Renewables, and Data Centre markets plus international expansion of Hiperpile technology.
