What Integrity Engineering does

Integrity Engineering (Scotland) Ltd is a privately held engineering services company established in 2016 and headquartered in Glenrothes, Fife, Scotland. The firm operates from a 20,000 sq. ft. ISO-approved manufacturing facility and serves the oil, gas, and broader energy industries worldwide. The company was founded by a team whose members hold collective decades of first-hand sector experience, with that expertise itself positioned as a primary commercial asset.

The company's offering spans four interconnected service lines: Valves & Controls (supply, refurbishment, spares, and maintenance of valves and actuators, including the MIR Valve product brand); Manufacturing (full machining, welding, assembly, and pressure testing using MAZAK, DOOSAN, and FADAL CNC equipment with tolerances up to 800mm, plus Giddings & Lewis horizontal and vertical boring up to 10 tonnes); Inspection (coordinate measuring machine (CMM), metallurgy, welding inspection, and non-destructive testing (NDT)); and Sub-Sea Services (supply, repair, maintenance, and inspection of risers and associated sub-sea equipment). Underlying technology is conventional precision engineering; no AI/ML, software platform, or digital product layer is described.

The business model is enterprise B2B, combining one-time product supply (valves, sub-sea equipment) with contract-based professional services (machining, welding, NDT, maintenance). Pricing is quote-based and not publicly disclosed. The go-to-market is direct enterprise sales with department-specific contact points, and industry credentials (ISO, DNV, Achilles FPAL pre-qualification) are used as qualifying trust signals for energy-sector procurement processes. No customers are publicly named, no revenue, headcount, or funding data is disclosed, and the company appears to remain in a small-scale, privately held posture.
