About VINCI Construction

ILIOS Overview

ILIOS is the Construction Partner for the UK’s STEP (Spherical Tokamak for Energy Production) fusion programme, the UK’s world‑leading programme to design and build a prototype fusion energy power plant at West Burton in Nottinghamshire.

ILIOS is a consortium led by a joint venture between Kier and Nuvia, supported by AECOM, AL_A and Turner & Townsend, bringing together extensive experience across major national infrastructure, nuclear and safety‑critical engineering, complex site transformation, programme and cost management, and world‑class design.

Working as part of the public–private sector integrated team led by UK Fusion Energy (UKFE), a wholly owned subsidiary of the UK Atomic Energy Authority (UKAEA), ILIOS is embedded in the programme as STEP transitions from planning into delivery.

The consortium supports the design and construction of buildings, infrastructure and facilities across the STEP site, alongside constructability, programme planning, site management, supply‑chain engagement and project controls, helping to ensure delivery is safe, buildable and fully integrated with the wider programme.

The appointment of ILIOS marks a significant milestone in the UK’s transition to clean energy and supports STEP’s mission to demonstrate fusion energy and develop a world‑leading fusion supply chain, creating long‑term economic and skills opportunities for the UK.
