Factory staffing stalls as output soars: what it means for maintenance teams

UK factories are busier than they've been for two years, but they aren't hiring to match. The final S&P Global UK Manufacturing PMI for October came in at 52.8, its highest score since May, signifying a period of significant growth within the sector. Staffing levels, though, were unchanged for the first time in six months, and some firms held back on adding capacity to offset rising labour, transport and raw material costs.

Supply is tighter too. Input prices rose at one of the sharpest rates in four years, with electronics among the items named, and supplier lead times lengthened by one of the greatest extents in four years.

For maintenance teams, that means more running hours on the same plant, with the same people and slower parts. Engineering time is now the constraint. So how can a small maintenance team reduce downtime? Start by looking at where that time actually goes.

Where maintenance time disappears

On most sites, the repair itself is rarely the longest part of a breakdown; it's often the factors around it:

• Finding the fault. Working through a circuit by elimination while the line stands idle.
• Waiting for parts. Longer lead times can turn a quick swap into a long stoppage.
• Chasing suppliers. Raising orders, approvals and delivery queries across several accounts for routine items.

You can shorten each of these without adding to the headcount.

Get faster diagnosis with the right test kit

Most fault-finding time goes on narrowing down where the problem is. Yet, a few measurements taken in the right order can rule out large parts of a system quickly.

• Measure current without breaking the circuit. A clamp meter shows a motor's running load while it works. Comparing current across all three phases quickly spots imbalance, and a multimeter covers voltage, continuity, and resistance.
• Check insulation before it fails. An insulation resistance test picks up deteriorating windings and cables, particularly on motors that run hot or sit in damp conditions. A reading that falls over successive tests tells you more than a single value.
• Split instrument faults into parts. On 4–20mA loops, a loop calibrator can inject a known signal or measure the one present. That shows whether the fault sits in the transmitter, the wiring or the control system.
• Look for heat. Thermal imaging shows loose terminations, overloaded breakers and warm bearings without touching live equipment. Compare similar components under similar load: a difference between phases is often more telling than the temperature itself.

Whichever instruments you use, be sure to record the readings. A trend across several visits says far more than any one measurement.

Move from reactive fixes to preventative maintenance

Preventative maintenance means inspecting and servicing equipment on a schedule, so faults are found and fixed before they cause a breakdown. The same test tools earn their keep here. A simple survey routine on your most critical plant catches problems while there's still time to plan the repair:

1. List the assets whose failure stops production. It's the same list your critical spares sit against.
2. Take a thermal image of each panel, motor and drive under normal load, and save it as a baseline.
3. Repeat at a fixed interval and compare. A connection running hotter than last time, or hotter than its neighbours, goes on the planned work list.
4. Record insulation resistance on key motors and watch the trend. A steady fall is an early warning.

Keep the routine short enough that it actually gets done. Planned work can be fitted around production, and parts can be ordered before they're needed, which matters more when lead times are stretching.

Less time on admin

Routine buying shouldn't eat into engineering hours. A few habits help:

• Keep a standard reorder list for consumables and common spares, such as fuses, terminals and test leads, so restocking is quick.
• Buy through fewer accounts where you can. Fewer suppliers means fewer invoices, approvals and delivery queries.
• Review your critical spares list and check stock against it, especially for parts whose lead times have stretched.

Small changes like these give engineers back time without anyone being added to the team. For teams that want to consolidate, Rapid supplies test equipment, hand tools and electrical spares through a single business account.

Frequently asked questions

How can a small maintenance team reduce downtime?

Focus on the time around each repair rather than the repair itself. Use test equipment such as clamp meters, insulation testers and thermal imaging cameras to find faults faster, run simple condition checks on critical plant so problems are fixed on your schedule, and cut admin by buying routine spares through fewer accounts.

What test equipment helps maintenance engineers find faults faster?

A clamp meter and multimeter cover most electrical fault-finding, an insulation tester picks up deteriorating motor windings and cables, a loop calibrator checks 4–20mA instrument loops, and a thermal imaging camera shows hot connections and bearings without touching live equipment.
