About Us

We are an agile, direct delivery specialist contractor to both the water industry and wider water environment, with an emphasis on delivering innovative, low carbon and high-quality reliable solutions.

Currently holding 29 frameworks, we work with most of the UK’s water companies and the Environment Agency - either directly or through their major supply chains - to deliver high value, low carbon solutions across their asset estates. This includes works on potable water, wastewater treatment centres and nature-based ‘green’ and ‘grey’ solutions that deliver smart, low carbon environmental engineering.

Our Purpose, Vision & Strategic Goals

With the intensified global focus on the effects of carbon emissions and their impact on the climate and biodiversity, many businesses have accepted the urgent need to prioritise sustainability.

In recognition of this, Stonbury has reassessed its Purpose, Vision and Strategic Goals, putting sustainability at the heart of our culture and everything we do.
