Planned Preventative Maintenance vs Reactive Repairs: Why PPM Pays Off

Every site that runs on reactive maintenance can point to a moment it regretted it — a boiler failing in December, a fire door closer giving way the week before an inspection, a leak that had clearly been building for months before it finally showed itself. Planned preventative maintenance exists to move those moments from crisis to calendar entry.

What PPM actually is

Planned preventative maintenance is scheduled, proactive servicing and inspection of building systems and equipment, carried out on a set frequency regardless of whether anything currently appears wrong. It covers the statutory essentials — fire alarm and emergency lighting testing, gas and electrical inspections, water hygiene checks — as well as the wider building fabric and plant that keeps a site running.

Why reactive maintenance costs more than it looks like

Reactive repairs feel cheaper in the moment because there's no ongoing spend when nothing's visibly wrong. But the real cost shows up elsewhere:

• Emergency call-out rates are routinely higher than scheduled work, sometimes significantly so
• Failures rarely happen at convenient times — out of hours, during peak use, or right before an inspection
• Small issues become bigger ones — a minor fault left unaddressed often causes damage well beyond the original component
• Compliance gaps compound — a missed statutory test doesn't just risk the equipment, it risks a finding at inspection
• Disruption costs more than money — closed rooms, cancelled bookings, unhappy staff or tenants

What a decent PPM schedule looks like

1. A full asset register covering everything that needs servicing, tested or inspected — not just the obvious statutory items.
2. Correct frequencies for each item, based on manufacturer guidance, statutory requirements and how the equipment is actually used.
3. A forward calendar, not a reactive list, so work is planned around the site's schedule rather than squeezed in around emergencies.
4. Clear record-keeping showing what was done, when, and by whom — the same evidence an inspector or insurer will ask for.
5. Regular review as the building, its use, or its equipment changes.

The switch is rarely as disruptive as it sounds

Moving from reactive to planned maintenance doesn't have to mean a big-bang overhaul. Most sites get there by building the asset register first, then phasing in scheduled servicing for the highest-risk and highest-cost items, and expanding from there.
