Our experience allows us to anticipate challenges, minimise risks and maintain operational efficiency throughout every project.

Supporting Landmark Power Station Closures

Hargreaves Services has supported the decommissioning of some of the UK's most significant power stations, including Ratcliffe-on-Soar and Cottam.

At Ratcliffe-on-Soar, our long-standing involvement with the site, dating back to 1994, provided the detailed operational understanding needed to support the early stages of decommissioning. Working alongside Uniper, we carried out critical preparatory activities including plant isolation, equipment removal, waste management and materials recovery.

At Cottam Power Station, our teams supported a wide range of decommissioning activities, from asset recovery and cable reclamation through to site clearance and environmental management works. We also helped process and repurpose legacy ash materials, supporting more sustainable outcomes and reducing waste.

These projects demonstrate the value of combining practical experience with specialist expertise, ensuring sites are safely prepared for redevelopment and future use.

Safety and Environmental Responsibility

Decommissioning large-scale industrial facilities presents unique operational and environmental challenges. From isolating live systems to managing hazardous materials and heavy lifting operations, safety remains the priority at every stage.

Hargreaves Services manages risk through meticulous planning, detailed assessments and ongoing workforce training, helping clients meet regulatory requirements while protecting people, assets and the environment.

The Know-How to Deliver

Every power station presents its own challenges, but successful decommissioning always relies on the same foundations: experience, planning and expert execution.

Hargreaves Services has the know-how to safely decommission complex industrial assets, recover value where possible and prepare sites for their next chapter.

Whether supporting the closure of a major power station or delivering specialist industrial services, our teams bring the expertise needed to get the job done right.
