Bridgwater Tidal Barrier

Strong growth driven by infrastructure investment

Infrastructure delivered another year of strong growth, with revenue increasing by 10% and adjusted operating profit increasing by 16% to £129m (FY25: £11Im), and with margin improving to 5.5% (FY25: 5.2%). Growth was driven by increased activity across water, continued investment in road infrastructure, such as the A66 dualling and M6 Lune Gorges viaduct projects, and sustained delivery in rail at both a regional and national level.

The water business performed particularly strongly as customer investment accelerated under AMP8. Kier now holds leading positions on frameworks worth approximately fillbn across ten water customers and is delivering more than 140 live projects across the UK.

The order book increased 14% to £7.4bn, reflecting significant new work secured across highways, water, rail and energy, providing visibility equivalent to more than three years of divisional revenue.

Our long-term collaborative relationships and strategic framework positions are underpinned by our integrated design, build and maintain model. Our breadth and depth of capability and focus on performance excellence and digital innovation are driving strong, resilient, repeatable growth across our target sectors, including water, where AMP8 investment increased project activity and delivered better customer outcomes.

Strong delivery, high-quality pipeline and growing lifecycle capability

The Construction division delivered a resilient performance in FY26, with revenue increasing by 4% as major projects, including HMP Glasgow, entered full delivery phase. Our order book remained strong at approximately £4.5bn, providing excellent visibility of future revenue. During the year, we secured positions on several strategically important frameworks, further strengthening our future pipeline.

Alongside our core construction activities, Kier Places continued to enhance our customer offering through long-term facilities management, housing maintenance, refurbishment and specialist services. Representing approximately 15% of divisional revenue in FY26, the business provides resilient recurring revenue streams while strengthening customer relationships and creating opportunities across the wider Group. Together, our construction and lifecycle capabilities position us to support customers throughout the lives of their assets, from development and delivery through to operation and maintenance.

Since joining Kier, I have been struck by the strength of our culture, the capability of our teams and the ambition across our Construction business to deliver high-quality built assets with greater certainty for our customers. That has been evident throughout the year, with another strong performance from the Construction business and continued demand across our core sectors.
