Project Management Expertise

G & T, a leading independent construction consultancy, has been engaged to support TVL with a suite of project management services and to act as Principal Designer under the Construction (Design and Management) Regulations 2015 ("CDM"). G&T's proven expertise spans energy, advanced manufacturing and battery materials, with a strong record of managing programme risk and delivering major industrial facilities on time and on budget. Their appointment reinforces a de-risked pathway to construction and commissioning.

New Senior Appointments

TVL has also bolstered its leadership team with two senior appointments. Effective 1 September 2025, Gemma Cooper will join as Chief Commercial Officer, bringing over 15 years' experience in global commodity supply chains and contract negotiations. Gemma previously held senior roles at Johnson Matthey and has worked across strategic sourcing and partnerships in battery materials and speciality chemicals and has advised a range of industrial clients on offtake and global trading structures. In her new role, Gemma will lead feedstock, offtake, partnerships and commercial agreements critical to advancing the project.

A Chief Operating Officer has also been appointed, adding further operational strength as TVL transitions from FEED into construction. Details will be announced on formal commencement.

These appointments mark another milestone in de-risking the project and advancing towards delivery of the UK's flagship lithium refinery, designed to support the growth of Europe's battery and EV supply chain.

TVL CEO, Vikki Jeckell commented:

"Momentum continues to build at Tees Valley Lithium. By enhancing our delivery team with G&T and adding senior commercial and operational leadership, we are creating the foundations for successful project execution. This gives us greater confidence as we progress through FEED and prepare for Final Investment Decision."
