What GEOL LTD does

GEOL-CONSULTANTS LIMITED, trading as Geol Consultants Ltd (Companies House number 04102697), is a privately held UK site-investigation firm headquartered at Tectonic House, Unit 11 Queens Court North, Third Avenue, Team Valley Trading Estate, Gateshead, Tyne and Wear. The firm delivers geotechnical, geo-environmental, and coal mining risk-assessment services to construction, land development, and engineering-sector clients, primarily across the coalfield regions of England and Wales, with a particular focus on Coal Authority Development High Risk and Low Risk Areas.

The firm's core offering is a six-part service stack: Phase I Preliminary Contamination Risk Assessments (desktop studies), Phase II Ground Investigations (trial pitting, sampling, shell-and-auger, cable percussive, and rotary drilling), Coal Mining Risk Assessments (CMRAs) used in planning applications, Hazardous Ground Gas Risk Assessments covering methane and carbon dioxide following BS 8485:2015 and CIRIA C665, Remediation and Validation Works, and Flood Risk Assessments. Differentiation rests on the firm operating its own in-house fleet of specialist drilling rigs and calibrated ground-gas monitoring equipment, plus directly employed investigation teams — capabilities that the firm contrasts against competitors who subcontract drilling to third parties. Director Terry McMenam, a Chartered Scientist and Chartered Environmentalist with 30 years of Engineering Geology experience, was selected by The Coal Authority in 2017 to help develop its improved coal mining reports, and the firm holds specialist-contractor status for mine entry stabilization drilling and grouting works.

The commercial model is a sales-led, direct-services professional-services engagement: project-specific fees quoted through phone, email, or website contact form, with no publicly disclosed pricing and no intermediaries between the firm and its clients. Customer acquisition blends a content-driven website (geolconsultants.co.uk), organic social presence on LinkedIn/Facebook/Instagram/Twitter, and a strong referral loop in which satisfied customers and named accounts — including The Coal Authority, Sir John Hall, and LCC Bell Developments Ltd — recommend the firm to peers. Revenue is generated per project across the six service categories, supplemented by ongoing remedial and validation engagements and recurring specialist-contractor work for The Coal Authority. Constructionline Silver and CHAS accreditations are held to support eligibility for regulated and public-sector procurement.

Product overview

Geol Consultants Limited offers a unified suite of geotechnical and environmental site investigation services organized into six interconnected phases and specialized assessments. The core offering begins with Phase I Preliminary Contamination Risk Assessment (desktop study) for initial site screening, followed by Phase II Ground Investigation for detailed ground condition analysis. These investigative services are complemented by specialized Coal Mining Risk Assessments (CMRA) for sites in coalfield areas, Hazardous Ground Gas Risk Assessments for methane/carbon dioxide evaluation, and Remediation and Validation Works for contaminated land. Flood Risk Assessments provide additional environmental risk evaluation. All services are delivered through the company's own in-house drilling equipment and experienced investigation teams, providing turnkey solutions from initial assessment through to remediation validation.
