JN Bentley has published its 2025 annual review. The review looks back on the last 12 months in JN Bentley and its fully-integrated design and build companies, Mott MacDonald Bentley (MMB) and JBA Bentley. The review reflects on what was another positive period for the organisation – and its busiest ever – with a record £600m in revenue delivered with clients across the UK. The business welcomed new people and clients and made real progress where it matters most: health and safety. The launch of the company’s control of high energy hazards programme, alongside continued investment in new technology, is helping to make sites safer places to work – taking the business to a place where zero injuries will be a reality. The annual review covers core areas of the organisation – including a focus on people, safety and money - plus case studies that demonstrate the very best of JN Bentley, MMB and JBA Bentley. Please enjoy the read. We have a small number of printed copies of the annual review available. To request a copy, please email communications@jnbentley.co.uk.

The Mott MacDonald Bentley (MMB) project team responsible for delivering the UK's largest integrated constructed wetland (ICW) proudly took home the Centenary Award for projects valued over £5m, at the annual Institution of Civil Engineers (ICE) Yorkshire and Humber Awards. On behalf of Yorkshire Water, and working in partnership with Stantec, the pioneering 'first-of-its-size' scheme at Dearne Reach, Yorkshire, is now a benchmark for delivering low-carbon, nature-based solutions to support stormwater management and deliver water quality improvements. MMB designed and built thirteen adjacent wetland cells - housing over 350,000 plants of 52 different species - engineered to naturally treat effluent to improve 4km of the River Dearne. Using natural processes such as sedimentation, filtration and biological uptake, the ICW removes pollutants including ammonia, biological oxygen demand (BOD) and suspended solids. The solution is a sustainable alternative to traditional concrete infrastructure - which would have entailed 7,000 m³ of storm storage - and is creating many new thriving habitats. As the largest ICW of its kind in the country, Dearne Reach showcases the capability of the UK construction industry to deliver low-carbon, climate-resilient infrastructure at scale. Lessons learned from both design and delivery are already being shared across the industry, helping to drive continuous improvement and innovation in sustainable water management. In doing so, the project not only improves river water quality and biodiversity today but also strengthens the evidence base and confidence needed to accelerate adoption of nature-based solutions nationwide. Commenting on why the project deserved the award, the ICE judges said: "The Dearne Reach scheme is an exemplar for using nature-based solutions to respond to water challenges while delivering enhanced biodiversity and catchment-wide water quality benefits.” The judges were further impressed by the project’s use of digital tools and AI to optimise how the earthworks were managed, congratulating the team for their commitment to excellence every step of the way, from feasibility through to construction. Aerial view of the integrated constructed wetland cells at Dearne Reach Thanks to its innovative, industry-leading and sustainable approach, the project is now a triple award winner. In 2025 the team achieved National Gold at The Green Organisation International Green Apple Environment Awards, and also received the win for 'Going the extra mile' at the Civil Engineering Contractor's Association (CECA) Yorkshire and Humber Awards.

JN Bentley has passed 3 million hours worked without a reportable injury. The milestone – which includes all JN Bentley, Mott MacDonald Bentley (MMB) and JBA Bentley sites and offices – reflects the success of the company’s control of high energy hazards programme and ongoing commitment to achieving zero injuries and preventing occupational ill health. It is the second time in company history the milestone has been reached. The programme The high energy hazards programme focuses on identifying and controlling the most significant risks present on construction sites. Stemming from a research paper published by the Edison Electric Institute, the approach identifies the sources of high energy, those with the potential to cause serious injuries, and introduces the requirement to implement either a direct, or a minimum of two secondary controls to prevent harm. Over the last six months, the programme has been rolled out to 2,800+ colleagues – covering front-line, operational, commercial, design and business support staff – as well as client teams and the supply chain. JN Bentley site teams participate in a 'hazard spotting' exercise during the programme's roll-out Since then, the business has seen excellent engagement across all operations. The programme has been well received by clients, with some beginning to integrate this into their own operations. Recently, MMB achieved a 100% score from Yorkshire Water via their SIF (serious injury or fatality) prevention maturity report, which assesses contract partners on how well embedded high energy hazards and their controls are within operations. The business was recognised for three areas of best practice, resulting in an overall maturity rating of 'Innovating' – the highest level. Across the supply chain, increased collaboration and innovative thinking has led to the development of solutions that eliminate, reduce and isolate high energy – making site operations safer. JN Bentley hosts a supplier safety engagement day as part of the high energy hazards programme The control of high energy hazards is now fully embedded into business as usual across all operations, with colleagues continuing to share ideas that spark discussions around effective hazard identification and controls. Creating a great safety culture The engagement with the high energy hazards programme has been central to maintaining a great safety culture at JN Bentley – one where colleagues demonstrate their commitment by choosing safe behaviours, creating safe habits and constantly looking out for each other. Colleagues across the business demonstrate safety engagement by: Leadership – setting a positive example and discussing unsafe behaviours Knowledge – understanding company expectations and processes   Responsibilities – taking personal responsibility for controlling the hazards present Compliance – following the high standards required to keep everyone safe. In 2025 this engagement delivered record safety performance with the all injury frequency rate (AIFR) at its lowest ever level, and record numbers of positive intervention (PI) reporting, up 13% on 2024, and more individuals reporting than ever before. Since the roll-out, over 2,200 positive interventions reported relate to identifying and managing the risks associated with high energy hazards. These reports, known as ‘Talk Safes’ and ‘Made Safes’, keep people safe through positive safety conversations and by taking positive action, which both improve understanding, and influence behaviours. The company’s approach to high energy hazards was recently featured in the Environment Agency’s Current magazine (page 5)  – plus read more about JN Bentley’s safety strategy the company website .

Digital delivery OUR APPROACH Augmented reality We use the latest Augmented Reality (AR) technology in project design and delivery to help us better understand challenges on site, identify design or programme clashes early and improve the safety of the construction phase. Augmented Reality is an enhanced version of the real physical world that is achieved using digital visual elements, sound, or sensory stimuli delivered via technology. In terms of construction, it allows 3D digital models to be projected onto sites through a device, such as a tablet, phone, or headset. Case study: Project Munio We used Visual Live, an augmented reality tool, to visualise the position of construction elements and efficiently plan site works for Derby County Council. This helped the site team to better understand site constraints and plan the works safely as it was a very tight and complex site location. Case study: Grimsby On this scheme we used AR to visualise below ground services. Avoiding service strikes is critical when operating below ground, so having the ability to visualise services prior to digging makes avoidance much easier and improves excavation safety.
