From resistance welding systems in the automotive sector to high-specification components for aerospace and defence, WES Ltd is a Cornish precision engineering company redefining its future – and helping position Cornwall as a serious contributor to the UK’s advanced manufacturing and space ecosystem.
Established in 1979, WES has spent more than four decades building expertise in CNC machining and specialist materials engineering. Today, as the global industrial landscape shifts, the company is undergoing a strategic transformation – one that places Cornwall at the heart of their vision for advanced manufacturing.
For much of its history, WES operated primarily within the automotive industry, with around 70% of its business focused on resistance welding equipment. Alongside this, the company developed deep expertise in machining hard and exotic materials – engineered for extreme environments and long service life.
But the shift to electric vehicles has brought structural changes to the automotive market. Recognising the need to adapt, WES has undertaken a detailed strategic review – supported by engagement with the Cornwall Space Cluster – to identify future growth sectors. The outcome? A deliberate realignment toward aerospace, defence, and space.
Today, automotive accounts for closer to 20% of turnover, while WES is actively building its presence in advanced, high-growth markets where precision, quality, and regulatory excellence are critical. It’s a transformation that demonstrates how Cornwall’s established manufacturers are evolving to meet the demands of emerging sectors.
The company has been working with satellite technology organisations for over a decade, supplying high-spec components on a project basis. This work is typically low-volume and high-complexity – often single satellite builds – requiring exacting standards and materials expertise. This sits alongside larger aerospace batch runs and mid-volume defence projects, creating a balanced production model that supports resilience and flexibility.
While space is currently a developing area rather than a dominant revenue stream, it’s strategically aligned with WES’s capabilities and their 38-strong team’s expertise in precision engineering.
Being part of the Cornwall Space Cluster ensures WES remains closely connected to regional developments, including horizontal launch ambitions, and emerging space technologies. The cluster provides strategic market insight, skills forecasting, networking opportunities, and visibility at national and international events such as Space Tech Expo.
Innovation at WES is both practical and strategic; over the past two years, the company has made significant capital investments in advanced five-axis machining and automation. A new multi-pallet machining centre capable of running 24/7 – a huge £400,000 investment – will mark a step change in upcoming production capability.
These upgrades strengthen WES’s competitiveness in international aerospace markets, where high precision and efficiency are essential. Alongside physical infrastructure, the company is embracing digital transformation – exploring the potential integration of AI into programming and production workflows, moving toward paperless operations, and continuously optimising processes.
WES has also introduced an Innovation Manager role to explore internal improvements and product development opportunities. While operating primarily as a subcontract manufacturer, the team regularly suggests material enhancements, durability improvements, and manufacturing efficiencies to customers. Innovation here is about making components last longer, perform better, and be manufactured more effectively.
A core element of WES’s transformation has been achieving the certifications required to operate in highly regulated sectors. Recent milestones include AS9100 aerospace quality certification, Cyber Essentials Plus accreditation, membership of JOSCAR, the defence supplier accreditation platform, and work toward Defence Cyber Certification.
These steps align directly with UK priorities around supply chain resilience, national security, and high-value manufacturing capability. For WES, maintaining advanced engineering skills within the UK is a matter of long-term industrial sustainability – without continuous investment in machinery, people, and compliance standards, capability risks being lost overseas.
That’s why investment in people remains central to their strategy. The workforce combines advanced CNC machining expertise, specialist grinding capability, materials knowledge, and regulatory experience.
Apprenticeships have, and continue to be, fundamental to WES’s model – in a region where advanced manufacturing skills are in demand, developing talent locally isn’t optional, it’s essential. At one stage, half of the workforce had come through apprenticeship routes, and WES was recognised as a finalist in the National Apprenticeship Awards. Each year, the company typically recruits engineering apprentices alongside business support roles, working closely with Truro College, Cornwall College, and the University of Exeter. Senior leaders, including the Operations Director, began their careers as apprentices within the business.
Cornwall’s engineering heritage provides a strong foundation. The county’s industrial legacy – from mining to heavy industry – has embedded technical skill and practical engineering culture within the region. At the same time, emerging sectors such as floating offshore wind, space, defence, and critical minerals are reshaping Cornwall’s economic future.
WES says quality of life also plays a crucial role, crediting Cornwall’s work-life balance with supporting employee retention and wellbeing. Flexibility and culture are competitive advantages in attracting and keeping skilled engineers.
Being part of the Cornwall Space Cluster adds further value – offering ongoing collaboration and support across the region’s growing space ecosystem.
WES’s journey from automotive reliance to diversified advanced manufacturing demonstrates how Cornwall’s manufacturers are adapting, investing, and aligning with the future of UK industry. By combining infrastructure investment, workforce development, regulatory excellence, and regional collaboration, they’re proving that world-class precision engineering capability can thrive in Cornwall.
As the UK’s space ambitions grow, companies like WES are ensuring that the expertise, quality, and innovation needed for advanced manufacturing remains rooted firmly in Cornwall.
WES Ltd is a member of the Cornwall Space Cluster, part of Cornwall’s growing advanced manufacturing ecosystem supporting the UK space sector.
