Reducing environmental impact

Water companies are now tasked with meeting stringent targets and commitments 

With a strong commitment to helping customers reduce their environmental impact and adapt their built assets to address climate change challenges, SOCOTEC continues to lead the way in environmental stewardship.

In 2023, the UK Government issued the first revision of its 25 Year Environment Plan, placing a critical focus on mitigating impacts on the water environment.

Water companies are now tasked with meeting stringent targets and commitments through enhanced transparency and monitoring mechanisms outlined in the Environment Act.

Regulatory compliance

IETG, experts in planning, monitoring, and measuring, are uniquely positioned to support water companies and wider stakeholders across the UK in achieving regulatory compliance.

Their services, including flow surveys, water quality monitoring and sampling, pollution alarms, level monitoring, temperature and hydrogen sulphide monitoring, are instrumental in ensuring adherence to environmental regulations.

SOCOTEC's extensive portfolio

This acquisition further bolsters SOCOTEC's extensive portfolio, providing clients with comprehensive in-house solutions

Furthermore, 40SEVEN's specialist surveying services, encompassing topographical and measured building surveys, as well as underground utility and gas hazard surveying, aligns seamlessly with SOCOTEC's existing surveying and monitoring capabilities.

This acquisition further bolsters SOCOTEC's extensive portfolio, providing clients with comprehensive in-house solutions throughout the asset lifecycle.

Commenting on the acquisition, Nicolas Detchepare, CEO of SOCOTEC UK, said: "The acquisitions of IETG and 40SEVEN reinforce and diversify our existing environmental division. With the addition of remote monitoring capabilities, we are now the leading provider in the UK, supporting our clients in complying with the rigorous legislation established by the Environmental Act.

Pioneer in Remote monitoring

This acquisition solidifies SOCOTEC's position as a leader in remote monitoring and advanced geospatial solutions within Infrastructure, Utilities, Environment, and Construction. The acquisition supports our ambition to become the leading integrated player in the UK, helping businesses mitigate environmental impacts and build a more resilient, sustainable future,” said Nicolas.

Ian Edwards, Managing Director, IETG and 40SEVEN said: “We can see fantastic opportunities ahead for IETG and 40Seven and after 7 years of investment support from Bentley O-S, at this crucial time, we needed strategic investment and size, matched by a similar culture and drive to achieve our goals and continued growth strategy.

SOCOTEC provides the ideal platform and seamless transition, whilst bringing a strategic mindset, strong covenant, credibility, financial strength, and support, and providing future opportunities for our staff to thrive and develop. We are excited and looking forward to the next stage of our journey within the SOCOTEC Group.”
