What MANTHORPE LIMITED does

Manthorpe Engineering Ltd. (trading as Manthorpe Engineering) is a UK-based precision engineering and manufacturing company headquartered in Ripley, Derbyshire, operating from a 20-acre manufacturing facility that delivers bespoke high-integrity components and assemblies to customers in civil aerospace, nuclear marine, power generation, process plant equipment, and defence/military sectors. Its service portfolio covers machining, fabrication and welding (in carbon steel, Weldox, Duplex, Super Duplex, stainless steel and aluminium), assembly, installation and commissioning, dimensional inspection and metrology using coordinate measuring machines, NADCAP-accredited non-destructive testing (dye-penetrant and magnetic particle inspection), manufacturing engineering supported by Siemens NX CADCAM, and bespoke project and programme management.

The company sells on a project-based, quote-priced basis to enterprise customers through direct B2B engagement. Its customer base is dominated by long-cycle, safety-critical prime contractors, with disclosed multi-decade supply relationships to Rolls-Royce Submarines and BAE Systems Submarines in nuclear marine work, complemented by case-study work in civil aerospace gas turbine components (e.g., UltraFan casings, rings, seals, diaphragms and prismatics) and industrial process plant equipment (e.g., Saint-Gobain Gypsum). Revenue is generated through one-off manufacturing programmes and engineering services with no disclosed recurring licence or SaaS component.

Manthorpe is a private limited company operating as part of the Manthorpe Group, with no disclosed parent, investors, or M&A activity. It is currently investing in capacity expansion: a new Correa VERXA M machining centre ordered in 2024 is scheduled for delivery in February 2026 and assembly completion in June 2026, supported by facility groundwork. The company maintains a stack of industry certifications — NADCAP, JOSCAR, SGS & UKAS, Cyber Essentials, FPAL, ADS, and Midlands Aerospace Alliance membership — that act as gating qualifications for tier-1 aerospace, defence, and nuclear supply chains.
