PPM vs Reactive Maintenance

The Question Every FM Manager Faces

In the world of facilities management, the fundamental question is: "Do we maintain it now, or fix it when it breaks?" While reactive maintenance seems simple, EntireFM's data from over 100 UK commercial sites proves that it is the most expensive way to run an estate.

What Reactive Maintenance Actually Costs (It's Not Just the Callout)

The 'visible' cost of reactive maintenance is the emergency callout fee. However, the true cost is much higher. When an HVAC system fails in a data center or a retail unit's fire alarm system develops a fault at 3 PM on a Saturday, the costs include:

1. Premium Labor Rates: Emergency after-hours callouts are significantly more expensive.
2. Operational Downtime: Lost productivity or lost trade while waiting for a repair.
3. Collateral Damage: A leaking HVAC unit doesn't just need a repair; it often damages ceilings, carpets, and electrical equipment.
4. Shortened Asset Life: Equipment that isn't maintained works harder, burns more energy, and ultimately fails years earlier than its rated lifespan.

What PPM Costs vs What It Saves

Planned Preventative Maintenance (PPM) is a fixed, predictable cost. By performing routine tasks—filter changes, belt inspections, sensor calibration—we prevent the catastrophic failures that drive reactive spend.

Our analysis across 100+ UK commercial sites shows that a robust PPM strategy delivers:

• 40-60% reduction in emergency callout premiums.
• 12-34% total maintenance budget savings.
• 10-15% reduction in energy consumption due to optimized equipment performance.

When Reactive Is Acceptable — and When It Isn't

Reactive maintenance is acceptable for non-critical, redundant assets (e.g., a single broken office chair or a non-statutory light fitting in a back corridor). However, for any asset related to Statutory Compliance, Life Safety, or Business Continuity, a reactive-only model is a high-risk strategy.

The Hybrid Model: PPM as the Base, Reactive as the Safety Net

At EntireFM, we implement a hybrid model. We use the PPM schedule to ensure 100% compliance and system health, while our 24/7 helpdesk provides a rapid reactive safety net for the unpredictable issues that occur on any site. This creates a predictable budget and an operationally stable environment.
