Knights Brown £136m turnover: workload mix and AMP8 outlook for civils teams

30 Second Briefing
Knights Brown has reported 2025 turnover of £136m, up from £116m, with a gross margin of £15m and EBITA of £5.4m, equivalent to a 4% margin. The civils and construction contractor is active in coastal defence, port infrastructure and energy schemes, signalling a workload mix weighted to heavy civil engineering rather than building. Management is now positioning for AMP8 water-sector frameworks, where long-duration, programme-based contracts could materially influence future cashflow stability and resource planning for marine, pipeline and treatment-plant works.
Technical Brief
- Coastal defence workload implies ongoing delivery of marine piling, revetments, flood walls and beach nourishment schemes.
- Port infrastructure activity suggests quay wall strengthening, dredging interfaces and heavy-lift pavement construction for container handling.
- Energy-sector work likely centres on grid connections, substation civils and foundations for onshore wind or solar assets.
- Positioning for AMP8 points to future frameworks covering pipelines, treatment works and associated MEICA interfaces.
- Long-duration AMP8 programmes would require sustained marine plant availability and specialist piling, cofferdam and dewatering capability.
- Framework participation would also drive standardised design–build processes and repeatable temporary works solutions across multiple sites.
Our Take
Recent coverage of Knights Brown’s coastal defence work in Cardiff and the Norwich transmission and distribution hub indicates that a material slice of this revenue is now tied to resilience and energy-transition infrastructure, which typically offers more repeatable workbanks than traditional highways-only portfolios.
Within our 857 Infrastructure stories, Knights Brown appears more frequently in relation to regional and specialist packages than Tier 1 mega-projects, so a 4% EBITA margin at this scale signals that mid-market contractors can still secure reasonable returns without moving into the highest-risk, fixed-price national schemes.
