Following a landmark investment year, the company has achieved its highest-ever domestic sales since acquisition by Essar in 2011, reinforcing its position as a cornerstone of the UK’s energy security.
The growth seen in 2025 highlights the continued strong demand for refined products in the UK and the essential role of the refining sector.
Deepak Maheshwari, chief executive officer of EET Fuels, said: “I am delighted with the performance of Stanlow in 2025.
“This record-breaking year is a testament to the hard work and dedication of our entire team, who successfully navigated a major turnaround and delivered our best-ever domestic sales figures.
“I would also like to thank our customers for their support.
“Stanlow has been fuelling the UK for over 100 years and this performance highlights that it remains critically important to the wider UK economy.
“We are investing to ensure Stanlow is well-placed for a long-term sustainable future and, to secure this future, it is vital that the UK domestic refining sector remains competitive.
“This underscores the urgent need for refining to be included in CBAM, ensuring a level playing field when it comes to competing with high carbon imported fuels.”
Despite the complexities of a major infrastructure transition, 2025 was a record-breaking period for Essar Energy Transition.
Driven by its robust pan-UK strategy, the company has successfully leveraged its extensive supply infrastructure to grow market share and deliver value to its customers.
Operational throughput has seen a significant uptick, with volumes up eight per cent compared to 2024.
This growth is most visible at the refinery gantry, where dispatch volumes are now approaching all-time record highs, demonstrating the efficiency and reliability of the Stanlow site.
The record performance in 2025 was bolstered by growth across all business units.
Highlights also include a $100 million investment in a major refinery ‘turnaround’, one of the largest and most complex in Stanlow’s history.
A spokesman added: “Part of a $350m investment programme of improvement projects, this didn’t just maintain the site; it transformed it.
“The turnaround delivered an approximate eight per cent increase in throughput capability and saw the installation of the UK’s first hydrogen-ready furnace, a critical step in the refinery’s decarbonisation journey.
“The success of 2025 highlights the essential role of a thriving domestic refining sector.
“To ensure the long-term sustainability of this vital industry, Essar Energy Transition continues to advocate for the inclusion of refining in the UK’s Carbon Border Adjustment Mechanism (CBAM).
“This would ensure a level-playing field for industry and protect the UK from high-carbon imports.”
