About Us

JN Bentley is a leading civil engineering & construction company operating in the UK, directly employing over 1000 people.

Our 2016 turnover was £169 million, generated from projects predominantly in the water sector, but in other building and civil engineering markets too.

Over 80% of our business is derived through Mott MacDonald Bentley MMB - set up in 1999 to operate as a wholly integrated, co-located joint venture by combining all facets of design, programme management, site investigation and construction in one organisation.

The partnership was formed specifically to deliver long-term, high volume programmes of projects for the UK’s water companies throughout the industry’s rolling five-year Asset Management Plan (AMPs).
Since initial contracts for AMP3, MMB has grown substantially through AMPs 4 and 5, leading to new and extended appointments as AMP6 delivery partner for Yorkshire Water, Severn Trent Water, Anglian Water, United Utilities and Welsh Water.

In 2014, Mott MacDonald acquired Bentley Holdings Ltd (including subsidiary company JN Bentley Ltd).  This move was a natural progression in the highly successful 15 year partnership between the companies through MMB. Read more here.

As a business we work hard to develop lasting relationships with our clients and our business has grown largely from repeat work.

Our philosophy is simple – construction is about providing a service and as such we always work collaboratively and flexibly with our clients in a spirit of openness and honesty.

We believe that this positive approach to project management with clients has contributed greatly to our success.

We pride ourselves on working with clients to find innovative solutions to traditional construction problems and applying the latest information technology to help drive efficiencies and reduce waste in our processes without compromising on quality.

Our working ethos, experience and systems are ideal for ensuring the successful delivery of projects and programmes of work with clients of all sizes through both framework agreements and traditionally procured projects.
