(WO) — A coalition of UK energy producers, manufacturers, trade unions and industrial organizations has urged Labour MPs to support continued North Sea oil and gas development, arguing domestic production remains essential to the country's energy security, industrial competitiveness and long-term economic growth.

In a letter delivered Tuesday to all 403 Labour members of Parliament, the group warned that policy decisions made by the new government will determine whether the UK continues to develop its domestic resources or becomes increasingly dependent on imported oil and gas.

The letter, signed by executives and representatives from the offshore energy, chemicals, engineering, shipping and construction sectors, was presented at Westminster alongside an industry summit focused on the role of domestic energy production in supporting UK manufacturing and skilled employment.

The coalition argues the UK will continue to require oil and gas for decades and says policymakers should prioritize domestic production over imports to reduce geopolitical risks, strengthen supply chains and protect jobs.

"Energy security, economic resilience and reindustrialization depend on maintaining domestic energy production as well as greater investment in renewable and low-carbon technologies," said David Whitehouse, chief executive of Offshore Energies UK.

Whitehouse said the organization supports the government's lower-carbon ambitions but called for an "all-energy approach" that builds on existing industrial capabilities while advancing the energy transition.

Industry leaders also stressed the importance of reliable and competitively priced energy for UK manufacturing.

Steve Elliott, chief executive of the Chemical Industries Association, said access to secure, affordable energy is critical to attracting investment and supporting industries that supply materials for infrastructure, manufacturing and the energy transition.

Trade union leaders echoed those concerns. GMB General Secretary Gary Smith said continued domestic oil and gas production is essential to reducing reliance on imported energy while protecting jobs, communities and national security.

The campaign included coordinated displays on offshore installations and industrial sites carrying the message, "Back North Sea oil and gas. Not imports."

The appeal comes as the UK government weighs future policies affecting North Sea investment and production, with industry groups warning that reduced domestic output could increase reliance on imported hydrocarbons despite continued demand for oil and natural gas.
