For many manufacturers, productivity has traditionally been measured by investment. A new production line, faster machinery or greater automation often promised the biggest gains. Increasingly, however, manufacturers are discovering that their greatest opportunity lies elsewhere: ensuring the equipment they already own never unexpectedly stops.
Across UK manufacturing, unplanned downtime has become one of the most expensive operational risks. With labour shortages continuing, supply chains remaining under pressure and production schedules becoming ever tighter, even a short electrical or control system failure can quickly escalate into missed deliveries, overtime costs and dissatisfied customers.
As a result, reliability engineering is moving up the boardroom agenda. Rather than waiting for equipment to fail, manufacturers are investing in preventative maintenance, electrical health checks, control system upgrades and automation improvements designed to identify potential issues long before they bring production to a halt.
For Brierley Hill-based electrical control systems manufacturer and automation integrator Banelec, the shift reflects a wider change in how businesses view engineering support. Increasingly, maintenance is no longer regarded simply as a reactive service but as an investment in operational resilience.
Dean Banner, Managing Director of Banelec, believes manufacturers are becoming far more aware of the hidden costs associated with unexpected downtime.
“People often focus on the cost of repairing a fault, but that’s usually the smallest part of the equation,” he said.
“The real cost is everything that happens while production has stopped. Staff are standing idle, customer orders are delayed, deliveries are missed and management attention is diverted towards solving an avoidable problem. When you look at it like that, reliability becomes one of the best investments a manufacturer can make.”
Modern production facilities rely on increasingly sophisticated electrical control systems that connect machinery, robotics, conveyors, safety systems and utilities into one integrated manufacturing environment. While these systems deliver significant productivity improvements, they also require specialist engineering expertise to ensure they continue operating safely and efficiently.
Many factories are now operating equipment installed over several decades, with legacy machinery sitting alongside the latest automated production technologies. Maintaining those mixed environments requires engineers who understand not only modern PLC programming and automation integration but also the older electrical infrastructure that remains critical to day-to-day production.
Banner says manufacturers are increasingly asking Banelec to assess the overall resilience of their electrical systems rather than responding only when something fails.
“The conversation has changed considerably. Five or ten years ago, we’d often receive a call once production had already stopped. Today, more customers are asking us to review their control systems, identify vulnerabilities and recommend improvements before those issues develop into costly breakdowns.”
That proactive approach can take many forms, from upgrading ageing control panels and replacing obsolete electrical components through to improving system redundancy, modernising PLC hardware and introducing remote diagnostic capability that allows engineers to identify faults much more quickly.
It also reflects growing confidence in predictive maintenance strategies, where engineers use data gathered from electrical systems to identify signs of deterioration before failures occur. For manufacturers operating around-the-clock production, the commercial benefits can be substantial.
“Production Managers don’t remember the machines that work every day, but they will certainly remember the crane that stopped the factory.”
“Our job is to make sure those moments happen as rarely as possible. Good electrical engineering is often invisible because everything simply keeps working, but behind that reliability is careful design, planned maintenance and years of engineering experience.”
The increasing focus on resilience is also being driven by wider economic pressures. As manufacturers invest in reshoring production, automation and higher-value manufacturing, every hour of available production capacity becomes more valuable.
Rather than continually expanding factories, many businesses are seeking to maximise the output of existing facilities by improving equipment reliability and reducing unnecessary downtime.
For companies operating in sectors such as aerospace, nuclear, defence, food production and advanced manufacturing, where Banelec has extensive experience, system reliability is often critical not only for productivity but also for safety, compliance and product quality. Banner believes this trend will continue as manufacturers place greater emphasis on operational certainty.
“Every manufacturer wants greater productivity,” he said. “Sometimes the smartest investment isn’t another machine. It’s making sure the machines you’ve already invested in continue performing exactly as they’re designed to. Reliability isn’t something that happens by chance—it’s engineered from the ground up.”
As British manufacturers continue to invest in automation and digital technologies, dependable electrical control systems are becoming more than an engineering necessity. They are increasingly recognised as a strategic asset—one that keeps production moving, protects profitability and gives businesses the confidence to compete in an increasingly demanding global marketplace.
