Since 2020 the shift to consultancy-plus-delivery has increased recurring professional services revenue, improving margin resilience despite rail sector volatility.
Customer loyalty
Multi-year renewals on highways and water frameworks have raised customer lifetime value and reduced churn versus spot projects, supporting steadier revenue streams.
Targeted insight
Key account programmes use spend-cycle alignment (AMP/RIIO) and client archetypes to focus bids where win probability and margin potential are highest.
