UK Manufacturers Report Rising Quality Failures Linked to Skills Shortages and Supplier Variability

A new industry analysis has revealed a significant increase in quality defects across UK manufacturing sectors, with many firms attributing the trend to shortages of skilled workers and inconsistent supplier performance. The report, compiled by the Manufacturing Quality Forum - a collaboration of major engineering and production businesses - found that first-time-pass rates have fallen by as much as 18 percent in some sectors over the past year.

According to the findings, the decline in quality performance is being felt most acutely in precision engineering, electronics and food manufacturing, where small deviations in process control can lead to entire production runs being rejected. Several companies surveyed said they were experiencing “repeatable, predictable” defects stemming from upstream supply chains that had become more volatile since the pandemic.

“Many manufacturers have become heavily reliant on suppliers who themselves are struggling with staff turnover, skill gaps and outdated inspection processes,” said Martin Kemp, chair of the Manufacturing Quality Forum. “We’re seeing quality drift - not catastrophic failures, but a gradual erosion of consistency that is now showing up in customers’ audits.”

The report highlights that a growing proportion of nonconformities identified during customer audits relate to insufficient calibration records, incomplete process documentation and inadequate evidence of material traceability - issues that organisations normally expect to control through established quality management systems.

The Chartered Quality Institute (CQI) commented on the findings, warning that the pattern suggests deeper structural issues. A CQI spokesperson noted: “Quality isn’t just about checking products at the end of the line. It is about capability, competence and control across the whole value chain. When skilled inspectors leave and are replaced with temporary labour without the right training, quality inevitably suffers.”

Some businesses told the report’s authors that labour shortages had forced them to accelerate training programmes or reduce inspection intervals to keep production flowing. In several cases, quality managers said they were spending more time on corrective actions and fire-fighting than on preventive improvement activities.

Supply-chain disruption has compounded the problem. Firms reported greater variability in raw materials, especially metals, electronic components and packaging materials, with some grades arriving with incomplete certification or inconsistent properties. One senior quality manager in the automotive sector, speaking anonymously, said: “It’s not that suppliers don’t care - they’re firefighting too. But when one batch meets spec and the next one doesn’t, the whole process becomes unstable.”

Industry analysts say the quality downturn is beginning to have commercial impacts, with several manufacturers reporting an increase in customer complaints, rework costs and lost time due to inspections and containment actions. Some large OEMs have responded by tightening incoming-goods inspection regimes and demanding more rigorous evidence of supplier capability.

The Manufacturing Quality Forum has called for renewed investment in skills, particularly in metrology, inspection techniques and quality engineering. It also urged companies to strengthen supplier approval processes and increase collaboration on root-cause analysis.

“Quality issues rarely emerge out of nowhere,” Kemp added. “They are signals - early warnings - that systems aren’t coping with the pressures being placed on them. The companies that respond now, not later, will be the ones that retain customer trust.”
