JBA Bentley

What JBA Bentley does

JBA Bentley Ltd is a UK-based integrated design and build contractor specialising in flood risk management, coastal and tidal defence, mine water treatment, reservoir and water infrastructure, and emergency flood response. Formed in June 2013 as a joint venture between JBA Consulting (environmental and water engineering design) and JN Bentley (civil engineering construction), the company brings planning, design, environmental and water engineering capabilities together with self-delivered construction under one organisation. Its core product set spans seven service lines: pumping stations, structures, tidal and coastal works, multi-site programmes (including the Environment Agency's Asset Refurbishment Programme), mine water treatment, reservoirs, and a dedicated fast-response emergency service. Underlying technology includes an in-house Industry Leading Carbon Toolkit for real-time design-stage carbon optimisation, 3D and augmented reality tools for site planning and buried-services communication, LiDAR-based flood modelling, and Deep Soil Mixing for sustainable ground improvement. The company is part of the broader JN Bentley / Mott MacDonald Bentley / JBA Bentley group, which together employ 2,200+ people and delivered £600m of revenue in 2025; JBA Bentley Ltd itself was described in 2023 as a £50m+ turnover profitable business.

The business model is project-based B2B contracting, with revenue derived from competitive tenders and long-term framework agreements. Pricing is contract-by-contract, ranging from approximately £50k for minor works to over £30m for major projects, with the Environment Agency's Asset Refurbishment Programme alone exceeding £50m+. Customers are concentrated in the UK public sector: the Environment Agency is the anchor client across multiple frameworks (Water and Environmental Management, Marine and Coastal, Flood and Coastal Erosion Risk Management), with the Coal Authority a second major framework holder (mine water treatment). Secondary segments include water utilities (Yorkshire Water and seven of the UK's largest water companies via the Mott MacDonald Bentley joint venture), local authorities (e.g., Derby City Council), and select industrial and port clients (Associated British Ports, Rolls-Royce, CEMEX). The go-to-market is relationship-led, combining framework retention, early contractor involvement, emergency response capability and award-winning project delivery, with thought leadership at industry events such as Flood & Coast and the British Construction Industry Awards.

• Costain Group: Major UK contractor with strong positions in water, environment, and infrastructure. Competes directly for EA, water-company, and coastal-defence frameworks and is a relevant comparable for integrated delivery and water sector exposure.
• Kier Group: UK infrastructure and construction group with significant water, highways, and environmental infrastructure exposure. Competes for many of the same EA and local-authority frameworks as JBA Bentley.
• BAM Nuttall: UK civil engineering contractor within Royal BAM Group, active in flood defences, coastal protection, water infrastructure, and earthworks. Direct competitor for EA frameworks and comparable in scope of civil-engineering delivery.
• VolkerStevin: Specialist UK civil engineering contractor focused on water, marine, and flood-risk management. Closely comparable niche positioning around coastal and fluvial flood-defence work, often competing on the same EA framework lots.
• Skanska UK: UK arm of Swedish infrastructure group with active civil engineering and water infrastructure operations. Competes for major public-sector frameworks and brings comparable scale and sustainability credentials to bids.
• Galliford Try: UK construction group with environmental and infrastructure divisions. Relevant peer for water and environment framework work, particularly through its water business serving UK utilities.

Regional players

• JBA Consulting: European environmental engineering and management consultancy that co-owns JBA Bentley. Provides design and environmental engineering expertise upstream of JBA Bentley's construction delivery; relevant comparable for the design-side capability but operates in a different delivery model.
