What The LK Group does

The LK Group (legal entity: Leyden Kirby Associates T/A The LK Group) is a UK-based multi-disciplinary consultancy and specialist contractor headquartered in Manchester. The firm combines consultancy insight with direct contractor delivery across ground investigation, geotechnical engineering, contaminated land assessment, land remediation, demolition, bulk earthworks, project management, flood risk and drainage, structural engineering, invasive plants management, air tightness testing, and land drilling services. Technically, the firm operates an in-house drilling fleet that includes an all-terrain window sampling vehicle, a handheld hydraulic drilling system, a 110-volt electric dynamic sampling rig for fume-free indoor work, and diamond-tipped concrete coring equipment capable of extracting cores up to 250mm. It targets five primary customer segments: UK local authorities and government bodies, housing developers, blue light services (fire and police), commercial and industrial developers (including energy and telecommunications), and housing associations.

The business model is project-based professional services delivery: each engagement is scoped and quoted individually, with no public pricing. Revenue is generated through three streams — consultancy services (Phase 1/2 site investigations, geotechnical and contaminated land assessments, project management), specialist contracting (land remediation, demolition, bulk earthworks, invasive plant management), and testing services (air tightness, laboratory, gas and groundwater monitoring). The go-to-market is sales-led and heavily reliant on direct relationships, public procurement via OJEU/competitive tendering, and repeat engagement from named clients such as Trafford Council (10+ years), Mace, Caddick Construction, Taylor Wimpey, Willmott Dixon, Manchester City Council, Far East Consortium, West Yorkshire Fire and Rescue Authority, and Lancashire Constabulary. Distribution is direct B2B across England, Scotland and Wales, with no channel partners or resellers.
