What Renew Holdings does

Renew Holdings plc is a UK-listed (LSE AIM: RNWH) engineering services holding company that delivers multidisciplinary maintenance, renewals and asset care across the country's regulated critical infrastructure networks. Through a federation of independently branded operating subsidiaries — AmcoGiffen, Carnell, Clarke Telecom, Excalon, Envolve Infrastructure, QTS, Shepley Engineers, Browne, Seymour, Full Circle and others — the group serves four core end markets: rail (primarily Network Rail under long-term framework agreements), strategic highways and telecoms infrastructure (primarily National Highways and mobile network operators), energy (nuclear decommissioning and decontamination, electricity transmission and distribution, onshore wind O&M via Full Circle, and thermal generation support), and water and environmental (water company AMP8 asset maintenance and renewals, flood defence, specialist marine civil engineering and remediation). Service delivery is built on a directly employed workforce model with over 270 trainees, apprentices and graduates, 24/7 emergency response capability, and a network of regional offices across the UK plus a European headquarters in Amersfoort, Netherlands, following the October 2024 acquisition of Full Circle Group Holding BV for EUR 60 million.

The underlying technology stack is operationally intensive rather than software-native: specialist field engineering for track, civils, MEICA, EHV cable jointing, diving, filter drain refurbishment (StoneMaster), road worker protection (SafetyCam fleet) and wind turbine blade inspection and repair, augmented by Full Circle's 24/7 remote wind turbine monitoring service which provides real-time performance and predictive maintenance data. The group's portfolio is diversified across nuclear, power, wind, water, rail and highways, with no single end market dominating revenue concentration disclosures, and growth has been supported by sustained bolt-on M&A, including Full Circle (2024), Emerald Power (2025), and four additional 2026 acquisitions (Edwards Diving Services, Remar Safety, PWR-X and EDES).

Renew's revenue model is professional services delivered under long-term framework agreements and direct contracts with government, regulated utilities and infrastructure operators, with revenue recognised on a project/contract basis determined through competitive tendering; pricing is not publicly disclosed. The group exited its Specialist Building operations in 2024 to refocus as a pure-play engineering services provider. The most recent reported period (HY26) showed group revenue of £589.0 million and adjusted operating profit of £33.4 million at a 5.7% adjusted operating margin, with the FY26 company-derived analyst consensus pointing to approximately £1,189.8 million of revenue and £77.9 million of adjusted operating profit, against a record order book cited by management.

Direct peers

• Mears Group plc: LSE-listed UK infrastructure services group with a regulated-clients focus spanning housing maintenance, highways, and asset renewal framework agreements. Highly comparable go-to-market through direct workforce delivery to government and utility clients.
• Kier Group plc: UK infrastructure and engineering services group listed on LSE with overlapping framework exposure to Network Rail, National Highways and regulated utilities. Operates in similar multidisciplinary maintenance and renewals segment as Renew, making it one of the closest peer comparisons.
• Costain Group plc: LSE-listed UK infrastructure services group focused on transport, water and energy framework delivery. Direct competitor for Network Rail, AMP8 water, and National Highways framework bids with comparable business model and end markets.
• Babcock International Group plc: LSE-listed UK engineering services provider with material nuclear and infrastructure operations. Comparable in regulated-client base, specialist engineering credentials, and long-term framework contract model.
• J. Murphy & Sons Ltd (Murphy Group): UK infrastructure contractor with significant water, rail, energy and highways framework exposure. Direct competitor in multiple AMP8, Network Rail and DNO framework competitions and operates on a similar long-term framework contract model.

Broad incumbents

• AtkinsRéalis: Global engineering services and project management group with a large UK infrastructure practice via legacy Atkins business. Comparable in nuclear, water, transport and energy engineering service delivery but with a broader consultancy-led footprint.
• Jacobs Solutions Inc. Global infrastructure services and consulting firm with significant UK water, nuclear and transport practice. Comparable in regulated-client engineering services delivery but with a US-centric scale and consulting-led model.
• Serco Group plc: LSE-listed UK public services outsourcer with revenue from government and regulated clients across defence, justice, healthcare and transport. Comparable in operating model of long-term outsourced services to government but with broader sector breadth.
• Balfour Beatty plc: LSE-listed, larger UK infrastructure group operating across construction, infrastructure services and real estate. Overlaps with Renew across rail, highways and utilities framework work but with a much broader portfolio including major construction and concessions.

Others

• Mott MacDonald Group: Large privately-held UK-headquartered engineering consultancy with deep water, transport and energy practice. Adjacent rather than directly competitive: consultancy-led design work that often feeds Renew's delivery scope.
