The UK government has pledged to reach carbon neutrality by 2050 and, as such, is pushing ahead with significant investment in nuclear and renewable energies.

Assystem, as a leading provider of project management, design engineering & construction supervision services within the nuclear industry, has aligned its own strategy to support this switch to low-carbon energy, whilst also recognising transport and infrastructure systems to be a major factor in influencing the outcome of government policy.

By acquiring Logikal in 2023, Assystem reaffirmed their commitment to the UK’s energy transition by combining strengths with a long-established provider of expertise to the transport & infrastructure sectors. We deliver professional services within PMO project delivery, particularly in the areas of project planning, project controls, risk management and enhanced business intelligence.

Based on these solid foundations, our team continues to build on its existing capability and has ambitious plans to develop its reach within both the transport & infrastructure sectors and through the additional opportunities offered via the Assystem network within the nuclear sector.

Our objectives will ultimately be defined by our ability to attract and retain those talented individuals who share our vision and wish to join us in shaping the future.
