Roskerry

What Roskerry does

Roskerry is a privately held UK specialist construction subcontractor, founded in London in 2013 and headquartered at Cuffley, Potters Bar. The company delivers an integrated bundle of construction services — diamond drilling and cutting, groundworks, RC frames, basements, structural alterations, demolition, and hard landscaping — operating as a tier-2 trade contractor engaged by main contractors, developers, and property owners on projects across London and Cambridge. Its service mix has expanded progressively from a single discipline (diamond drilling) into a six-discipline offering, allowing it to take on multi-service packages such as the £10m Eddington S1+S2 groundworks contract with Bennett Construction and the £3m Grosvenor Gardens House cut-and-carve heritage project with Ardmore.

The technical foundation is mechanical rather than digital: Roskerry runs a fleet of BROKK robotic demolition plant, state-of-the-art diamond drilling rigs, hydraulic bursting and crunching equipment, and conventional groundwork/RC frame machinery. The technical edge lies in controlled, dust-free, vibration-free, low-noise demolition and precise structural alteration — capabilities that depend on capital-intensive equipment and skilled operators rather than software. The firm holds ISO 9001 (quality), ISO 14001 (environmental), ISO 45001 (occupational H&S) and CHAS accreditations, which are standard procurement gates for UK main-contractor tender lists.

Commercially, Roskerry generates revenue through project-based professional services contracts awarded via tender or direct negotiation, with disclosed ticket sizes ranging from £700k to £10m. The go-to-market is direct enterprise field sales targeting main contractors and developers; there are no resellers, distribution partners, or self-serve channels. Eleven enterprise clients are named in the public portfolio (Bennett Construction, Ardmore, Apollo Building Services, Woodford Interiors, Glencar, Third Space, Northvale Construction, JJ Rhatigan, MYCO, Appian, M&O Group, Bennetts). Pricing is project-specific and quote-based with no published rates.

Core offering

Roskerry is a UK specialist construction subcontractor delivering diamond drilling and concrete cutting, groundworks, RC frames, structural alterations, basement construction, controlled demolition, and hard landscaping. Services are delivered as integrated packages on construction projects valued from £700k to £10m, primarily as a subcontractor to main contractors, developers, and property owners across London and Cambridge.

Product overview

Roskerry is a specialist construction company offering precision drilling, groundworks, and structural solutions. The company operates as a unified service provider combining six interconnected construction service lines: Diamond Drilling (specialist concrete drilling and demolition with BROKK robotic equipment), Groundworks (bulk excavations, foundations, drainage, and road construction), RC Frames (reinforced concrete structures), Structural Alterations (cut and carve, temporary works, secondary steelwork), Hard Landscaping (paving, tarmac, external works), and Basement Construction (from design through to waterproofing completion). These services are delivered as an integrated construction offering rather than discrete software products, with projects typically combining multiple service lines such as the Eddington S1+S2 development (£10m groundworks), Grosvenor Gardens House (£3m structural alterations), and Mallord Street Thirdspace (£1m basement and structural works).
