What Stockton Drilling does
Stockton Drilling Limited, rebranded as Stockton Group in May 2026, is a UK-based specialist engineering contractor headquartered in Wakefield, West Yorkshire. Founded in 2000 by Fiona and Gearoid O'Connell, the company operates across three divisions: Drilling (Horizontal Directional Drilling and Direct Pipe trenchless installations), Pipelines (steel and HDPE pipeline installation), and Civils (groundworks, reinforced concrete, drainage, and external works). Stockton claims to be the only UK business owning the Herrenknecht Direct Pipe system — a single-pass hybrid microtunnelling and HDD method — and operates an owned fleet of specialist equipment including 750-tonne Direct Pipe machines, 250-tonne HDD rigs, and rigs ranging from 45 to 500 tonnes pulling force, capable of bore lengths up to 2 kilometres and pipeline diameters from 6 to 48 inches.
The company generates revenue through project-based contracts, appointed as either Principal Contractor or Subcontractor. Its customer base spans energy (Saipem, E.ON, SSE/Copenhagen Infrastructure Partners/Red Rock Power for offshore wind and gas pipeline projects), utilities (Scottish Water, Environment Agency, GMC Utilities), and construction/education/leisure (Britvic, York Racecourse, Leeds Beckett University, DVSA), with a substantial portion of work delivered as subcontractor to Tier 1 main contractors including Tilbury Douglas, Kier Construction, Lindum Group, and Henry Boot. Pricing is negotiated per-project and is not publicly disclosed. The company is registered in England and Wales (Company No. 04245895), is privately held by its founders, and operates with 11–50 employees.
Stockton maintains ISO 9001, ISO 45001, and ISO 14001 certifications, plus Achilles UVDB Verify, Constructionline Gold, CHAS Elite, and SSIP prequalifications, and acts as Principal Contractor under CDM 2015. Its marketing is content-led (website case studies, LinkedIn, industry awards), with no external funding, acquisitions, or subsidiaries identified. Technical track record includes the world's first remote TBM disconnect at the Beatrice Offshore Windfarm, a ~2km subsea HDD pipeline at Shapinsay (believed longest land-to-land subsea directional drilled utility pipeline in the UK), and five 550m HDD landfalls at the Morlais tidal energy project. In May 2026, the rebrand consolidated the three divisions under a unified identity to position the company for broader market participation across energy transition, hydrogen-ready pipelines, and continued infrastructure delivery.
