Mark Winspear is a Senior Test Manager with 11 years of focused experience building test and quality capabilities for large public-sector and utility organisations. He has a proven track record of transforming outsourced, waterfall testing into in-house, agile-first functions—most recently building and leading Global Test & Quality at National Grid and now serving at National Gas. Mark has delivered major automation frameworks (Selenium-based) integrated into CI/CD pipelines that realized multi-million-pound savings and operational efficiencies across HMRC and SFA programmes. He combines hands-on technical rigour with people-centred leadership—advocating a “One team” culture, psychological safety, and measurable excellence (Test NPS +92). An active SME and author, he reframes debates like “automation vs manual” to improve testing practice and has driven organisation-wide SAFe adoption and test assurance frameworks. He’s equally comfortable with tooling, metrics and commercial sourcing, and is known for turning complex governance and delivery challenges into repeatable, auditable quality outcomes.
