2025 UK North Sea Decommissioning Spending Hits Record £2.6 Billion
UK North Sea operators spent a record £2.6 billion ($3.5 billion) on oil and gas field decommissioning in 2025, with well-specific work costing £1.3 billion ($1.75 billion) across more than 250 wells. Over 100 wells were permanently plugged, but about 500 wells still await final abandonment, prompting the North Sea Transition Authority to urge faster progress. Cumulative spending through 2032 is projected to account for nearly half of total forecast decommissioning costs, a period the regulator calls the "decommissioning decade."
Decommissioning spending across the UK North Sea hit a record high in 2025, with total industry outlays reaching £2.6 billion (about $3.5 billion). Approximately 500 wells in the region remain scheduled for decommissioning and final abandonment, and the regulator has said operators need to accelerate this work.
In 2025 alone, operators spent about £1.3 billion (approximately $1.75 billion) on well decommissioning, covering work on more than 250 wells, of which over 100 were permanently plugged and abandoned. The North Sea Transition Authority noted that despite the increase in activity, roughly 500 wells have yet to be finally abandoned.
Looking over a longer horizon, cumulative decommissioning spending on the UK continental shelf through 2032 is expected to account for nearly half of total forecast expenditure, a phase the regulator has labelled the "decommissioning decade."
