About us
At National Gas, the work we do matters.
As Britain's national gas network, we help keep the lights on, businesses running, and homes warm by maintaining the critical infrastructure that transports gas across Great Britain. While providing the energy security Britain relies on today, we're also helping transform the network for a clean energy future.
Join us and help secure Britain's energy.
About the role
Join our Major Programmes team as an Assistant Investment Planner and help shape the future of Britain's energy infrastructure.
You'll support the development of investment initiatives that underpin our long-term asset strategy, helping to turn strategic priorities into practical, deliverable projects. Working closely with stakeholders across the business, you'll contribute to the planning and delivery of investments that support the future of the energy network.
Why this role matters
The decisions we make today will shape the reliability, resilience, and efficiency of the energy network for years to come.
In this role, you'll help turn asset strategies into well-defined investment opportunities that deliver value, meet regulatory requirements and support long-term business objectives. By developing data-driven investment cases and supporting major programme delivery, you'll play an important part in ensuring we invest in the right projects, at the right time, to meet the needs of customers and the energy system of the future.
