What Nexus Infrastructure does
Nexus Infrastructure plc is a UK AIM-listed civil engineering group (LSE: NEXS) operating through two wholly-owned subsidiaries: Tamdown Group Limited and Coleman Construction & Utilities Limited. Tamdown, with 50 years of operating heritage, provides earthworks, highways, substructures, basements and sustainable drainage systems for large multi-phase residential developments, serving the UK's largest housebuilders including Bloor Homes, Bellway, Dandara, Vistry and Taylor Wimpey. Coleman, acquired in October 2024, delivers civil engineering and building projects across regulated and infrastructure sectors including water treatment works, safety-critical rail (Coleman Rail division), highways and rivers & marine flood defence. The combined group employs approximately 200 staff and is headquartered in Braintree, Essex.
The business model is project-based and contract-driven, with revenue generated from earthworks, drainage, foundation and utility infrastructure works executed under long-term frameworks and multi-year site development agreements. Tamdown's projects typically span 5-10 years, while Coleman operates on Ofwat's AMP frameworks in water and Network Rail's CP7 plan in rail. Pricing is negotiated per-project with major enterprise clients; the group does not publish pricing and there is no software, SaaS, or licensing component. Distribution is purely direct enterprise sales to a concentrated base of housebuilders and regulated utilities in the United Kingdom.
In FY25 the group reported revenue of £65.9m (up 16% YoY), gross profit of £10.3m (up 34%), and an order book of £83.4m (up 61.6%), reflecting share gains in housebuilding and the first contribution from Coleman. Market tailwinds include Ofwat's AMP8 determination of £104bn (a 70% increase on AMP7) and Network Rail's CP7 plan of £43.1bn. Following the December 2022 disposal of TriConnex and eSmart Networks, the group is now focused entirely on core civil engineering for UK national infrastructure and housing supply.
