SGN Tech Stack

Gas distribution network operator for 6M homes across Scotland and southern England

Utilities Horley, Surrey 1,001–5,000 employees Founded 2005 Privately Held

SGN operates a critical infrastructure asset—the gas distribution network serving approximately six million premises across Scotland and southern England. The tech stack is legacy-heavy (Oracle ERP, Maximo, ServiceNow, SQL Server) with no active migrations, but the hiring surge (56 roles in 30 days) and project mix reveal an infrastructure company in operational flux: mains replacement design, digitization of as-laid drawings, and target operating model work point to modernization of core systems and records, while pain points around network inaccuracies and project budget adherence suggest friction between aging asset management practices and operational scale.
