RSL NDT

What RSL NDT does

RSL NDT Limited is an Aberdeen-headquartered, privately held supplier of non-destructive testing (NDT) equipment, consumables, rental assets, and UKAS-accredited calibration services, founded circa 1974 and operating with 11-50 employees. The company serves inspection contractors, fabricators, and asset owners across oil and gas, renewable energy, nuclear and defence, fabrication, aviation, railway, and civil engineering, with the first two verticals designated as primary. Its product portfolio spans ultrasonic flaw detectors and phased array instruments, eddy current flaw detectors, thickness gauges, hardness testers, dye penetrant and magnetic particle inspection (DPI/MPI) consumables and yokes, radiography equipment and consumables, UV inspection lamps, and visual inspection tools, with the company acting as authorized supplier for Magnaflux, Chemetall, Johnson & Allen, Dakota NDT, and GB Inspection alongside its own branded consumables (NEOPAINT, NEOCOL, NEOASTRA, SKL, LD, Lumor, Supramor, Ardrox).

The company derives revenue across four streams: one-time equipment sales, usage-based short- and long-term rentals of inspection instruments, professional service fees from in-house service/repair/calibration (including UKAS-accredited calibration for ultrasonic and eddy current instruments), and sales of certified ex-rental equipment. Distribution is enterprise field sales via direct phone, email, and website quote requests, with technical consultation positioned as a sales-led differentiator. A distinguishing capability is the in-house design and manufacture of subsea inspection systems, including the S.C.U.M.P.I System, Diver FMD, ROV Mounted FMD, and C-MAG System, engineered for diver- or ROV-deployed flooded member detection, magnetic particle inspection, and ultrasonic thickness/flaw monitoring in harsh offshore environments. Operations extend globally in claim with particular strength in the UK and European markets, supported by a Hamilton-based division under the KenGed NDT brand. The company is independently owned with no disclosed parent, external investors, or public listing.
