Green Cat Renewables

What Green Cat Renewables does

Green Cat Renewables is a privately held UK renewable energy consultancy founded in January 2005 by Gavin Catto and headquartered in Biggar, South Lanarkshire, Scotland. The company provides fee-based, end-to-end project development and management services for wind, solar, hydro, battery storage, and hybrid renewable energy projects across the full lifecycle — from feasibility and planning through engineering design, environmental assessment, geotechnical investigation, construction supervision, and operational asset management. It serves a diversified client base spanning farmers and landowners, portfolio developers, community groups, investors and lenders, and government and enterprise customers. The company operates through a vertically integrated group structure alongside sister companies Green Cat Contracting (civil/structural), Green Cat Geotechnical (ground investigation), Prelec (electrical/ICP), and Green Cat Renewable Developments (project holding), enabling single-source delivery without third-party handoffs.

Technically, Green Cat Renewables combines a multidisciplinary in-house team of over 40 engineering, environmental, geotechnical, noise, grid modelling, and project management staff with proprietary assets including an expanded ZX 300 ground-based wind Lidar fleet for bankable wind resource measurement. It holds ISO 9001, ISO 14001, OHSAS 18001, and ISO/IEC 17025 certifications and operates from three Scottish offices (Biggar, Edinburgh, Livingston) plus a Canadian arm in Calgary, Alberta. The company has delivered over 800MW of renewable capacity across more than 420 projects, with 100+ planning consents totalling 273MW and 90% of consents determined at local authority level. Revenue is generated through project-based professional consultancy fees and ongoing facility/asset management contracts, with all engagements scoped and quoted per project; pricing is not publicly disclosed and there are no self-serve or channel-based distribution mechanisms. Marketing is relationship-driven through referrals, industry events, project case studies, and earned media coverage.
