GROUND-GAS SOLUTIONS (SCOTLAND) LIMITED

What GROUND-GAS SOLUTIONS (SCOTLAND) LIMITED does

Ground-Gas Solutions (GGS) is a UK-based environmental consultancy founded in 2009 by Simon Talbot that specialises in continuous ground gas monitoring, analysis, and interpretation for contaminated land, built environment, and infrastructure clients. The company deploys two proprietary in-borehole monitoring instruments — the GasClam, developed with the University of Manchester and brought to market in 2009, and the Gas Sentinel, an internally developed telemetry-enabled device launched in 2018 with interchangeable sensors for methane, carbon dioxide, radon, VOCs and other hazardous gases — supported by the Unity online data portal and the DataPack reporting format. GGS operates the largest fleet of continuous ground gas monitoring devices in the UK and has delivered over 1,000 projects across residential, commercial, mega-warehouse, landfill, rail, and bridge infrastructure settings.

Revenue is generated primarily through professional-services monitoring and risk-assessment contracts (continuous monitoring, verification, sub-floor void monitoring, baseline and landfill compliance monitoring, health and safety monitoring), supplemented by specialist consultancy (desk studies, mitigation design, expert witness), training (the long-running "A-Z of Ground Gas" two-day course priced at £165-£425+VAT per attendee), and a six-webinar annual programme (free introductory plus £30 premium). Go-to-market is sales-led via direct engagement with developers, infrastructure operators, property managers and local authorities, and via sub-consultant relationships with geo-environmental firms such as Sweco, GeoDyne and Delta-Simons. The company is privately held, headquartered in Stockport, with regional offices in Falkirk (Scotland), Stevenage and Milton Keynes, ISO 9001 accredited, and transitioned leadership from founder Simon Talbot to long-time colleague Joao Marcos Dyer in 2025.
