Decommissioning Spending in UK North Sea Hits Record High

In 2025, decommissioning activities in the UK North Sea reached a record-high spending level of £2.6 billion ($3.5 billion), reported the North Sea industry regulator. Well decommissioning constitutes roughly half of the projected costs until 2032, according to the North Sea Transition Authority's annual report. The UK North Sea presently has around 500 wells waiting for decommissioning and final abandonment.

In the previous year, operators allocated approximately £1.3 billion ($1.75 billion) to well decommissioning, involving more than 250 wells and over 100 reaching final abandonment status. Despite this increase in activity, a backlog of approximately 500 wells awaiting final abandonment persists, according to the NSTA. With over 1,000 additional wells projected to be decommissioned within the next five years, the industry must significantly ramp up its efforts to meet regulatory expectations and maintain the necessary supply chain resources.

Decommissioning spending is anticipated to surpass capital expenditure by 2029 as the UK North Sea matures, as few new oil and gas projects have been approved recently. The Labour Party's upcoming Prime Minister, Andy Burnham, is expected to show more support for new projects compared to his predecessor, Sir Keir Starmer, who advocated for a permanent ban on new drilling.
