At Oldham Engineering Ltd, we have built our reputation over more than 160 years on the promise of engineering excellence. Whether supplying nuclear, defence, oil & gas, subsea, rail, aerospace, power generation or general industrial sectors, we take pride in offering highly‑skilled, fully integrated turnkey complex assemblies to clients worldwide.
Complete Project Management Under One Roof
From the earliest concept discussions through to final commissioning, our in‑house project management team ensures that every stage of your project is managed seamlessly. We handle raw material procurement, coded fabrication, heavy and precision machining, complex assembly, thorough testing and final delivery. With everything happening under one roof, clients avoid the headache of coordinating multiple contractors and can enjoy significant reductions in lead times and project overheads.
Expert Complex Assembly and Testing
Our 30,000‑sq ft assembly bay, supported by a workforce of experienced fitters and engineers, is capable of handling mechanical, electrical, hydraulic and pneumatic systems: ranging from small, precision‑machined components to large and heavy turnkey assemblies.
This capability is vital not only for bespoke prototypes but also for batch‑produced items destined for repeated use. Before dispatch, we carry out comprehensive testing including static and dynamic testing, pneumatic and hydraulic pressure evaluations, load testing and operational simulation. This ensures reliability, safety and performance long before your equipment reaches site.
Serving Critical Industries with Quality and Integrity
We are recognised as a trusted supplier to demanding industries such as nuclear and defence. With many thousands of approved weld procedures and certifications including ISO 9001:2015 and AWS D1.1, we offer the kind of high‑integrity manufacturing, fabrication and assembly that these sectors require.
Whether manufacturing subsea frames for offshore operations, heavy structural items or complex mechanical assemblies, our strict quality control and extensive documentation; including lifetime traceability; give our clients confidence in the durability and compliance of their equipment.
