Welligence UK M&A | Serica Energy acquires Spirit Energy’s Southern North Sea assets

January 8, 2026

Serica Energy’s acquisition of Spirit Energy’s Southern North Sea portfolio reshapes its UK gas production base. The transaction brings equity in Cygnus, plus interests in Clipper South, Greater Markham and surrounding infrastructure. Serica secures low cost, low emission gas production, extends tax efficiency and broadens its footprint across multiple UK hubs.

For Spirit Energy, the sale continues its managed exit from upstream and supports a pivot toward energy transition projects. Retained interests in the Morecambe hub underpin future CCS opportunities, while Serica inherits later life decommissioning exposure.
