Cardiff’s manufacturing economy is more diverse than its public image suggests — defence electronics at General Dynamics Oakdale, rail manufacturing at CAF Newport (just over the border), food processing through the Brains brewery and a substantial food-and-drink cluster, and a tier of precision engineering supplying the wider South Wales industrial base. Apex arranges commercial insurance for Cardiff manufacturers. We’re an independent Bristol broker. Call 0117 325 0027 to discuss your cover.
Cardiff’s manufacturing identity has been shifting steadily — heavy industry has declined since the 1990s, but specialist manufacturing, defence electronics, food processing and rail engineering have built up to fill the gap.
General Dynamics UK operates a major site at Oakdale (just north of Cardiff) producing defence electronics, communications systems and the British Army’s BOWMAN and MORPHEUS communications platforms. The supply chain into General Dynamics runs to dozens of South Wales SME manufacturers — electronics assembly, cable looms, machined components, surface treatment, testing. Manufacturers supplying GD UK typically need to meet MoD supplier insurance requirements, which carry specific liability and cyber clauses.
Rail manufacturing is a meaningful Cardiff-region cluster. CAF (Construcciones y Auxiliar de Ferrocarriles) operates a major rail vehicle manufacturing facility at Llanwern (Newport border), assembling trains for UK operators. The supply chain runs deep into South Wales precision engineering.
Tata Steel Llanwern sits just over the border in Newport but its supply chain reaches into Cardiff machining, surface treatment and fabrication businesses. Closer to home, Brains brewery is the most visible food-and-drink manufacturer, though Brains’ brewing operations have changed shape since 2020. The wider Cardiff food processing base includes confectionery, bakery, brewing and food-service preparation operating from industrial estates at Llanishen, Wentloog and the wider Cardiff Bay enterprise zone.
Precision engineering and component manufacturing sits across the Wentloog, Treforest, Capital Business Park and Cardiff Bay industrial estates. Tech-adjacent manufacturing — IoT hardware, electronics assembly, instrumentation — is supported by the wider Cardiff University engineering ecosystem and the Compound Semiconductor Catapult presence (officially based at Newport but drawing Cardiff supply chain).
A few cover considerations specific to Cardiff manufacturing:
US/Canadian Products Liability extension is relevant for any manufacturer exporting to North American customers — defence electronics, precision components for aerospace, food and beverage exports.
Welsh language documentation can be relevant for any manufacturer operating Welsh-medium safety signage, training materials or public-facing communications. Most major UK insurers support Welsh-language claims documentation, but we’ll coordinate that where needed.
COMAH (Control of Major Accident Hazards) regulations apply to a small number of large Cardiff-region chemical and storage operators. For sites with COMAH exposure, the insurance structure differs substantially from standard manufacturing cover.
Standard cover lines for a Cardiff manufacturer include:

Cardiff is 55-70 minutes from our Bristol office depending on Severn crossing traffic. We don’t have a Cardiff office — we’re a Bristol broker who serves South Wales. Site visits for manufacturers are arranged on a planned basis, and we’ll usually do them when a survey adds value rather than as a routine.
What we offer Cardiff manufacturers is access to a UK insurer panel that includes underwriters who understand defence supply chain, rail manufacturing, food processing, and the wider South Wales industrial base. Welsh-language claims documentation is supported by all the major manufacturing insurers we use.
