Reactive vs. Planned Preventive Maintenance:
The True Cost Comparison
Most operations managers know PPM is better — but few have seen the numbers side-by-side. This guide uses real-world data from 200+ UK industrial sites to quantify the gap.
Reactive Maintenance
Fix it when it breaks
- ✕ Unplanned stops — no warning, no preparation
- ✕ Emergency parts at premium prices
- ✕ Production losses compound over time
- ✕ Safety risks increase with aged equipment
- ✕ Cascading failures damage adjacent assets
- ✕ Engineer overtime & premium callout rates
Planned Preventive Maintenance
Prevent it before it happens
- ✓ Scheduled visits — production kept running
- ✓ Parts pre-sourced at standard pricing
- ✓ Fixed, predictable monthly/annual cost
- ✓ Compliance maintained automatically
- ✓ Asset lifespan extended by 60–80%
- ✓ Engineering resource planned, not scrambled
Annual Cost Breakdown — Typical Mid-Size Operation
Based on a single critical asset (conveyor / pump / gearbox) in continuous production. All figures in GBP.
- Reactive
- With PPM
£54,500 annual saving per critical asset
Despite PPM service contract — net saving after all costs
5-Year Cost Trajectory
Reactive costs increase ~8% annually as equipment ages. PPM costs decline as asset condition improves.
- Reactive
- With PPM
5-year reactive total: ~£519k | With PPM: ~£182k | 5-year saving: ~£337,000

| Factor | Reactive | With PPM | Verdict |
|---|---|---|---|
| Failure Response | After breakdown occurs | Prevented before it happens | PPM ✓ |
| Cost Predictability | Unpredictable spikes | Fixed, budgetable monthly fee | PPM ✓ |
| Asset Lifespan | 40–60% shorter | Extended by 60–80% | PPM ✓ |
| Parts Availability | Emergency sourcing, premium | Stocked & planned | PPM ✓ |
| Operational Risk | High — cascading failures | Low — contained & monitored | PPM ✓ |
| Initial Investment | None (until failure) | Service contract required | Tie |
| Emergency Callouts | 8–12× per year (average) | 0–2× per year | PPM ✓ |
| Warranty Validity | Often voided by neglect | Maintained through compliance | PPM ✓ |
Downtime Costs by Industry
Typical hourly production loss + compliance risk, per sector
| Sector | Cost Per Hour Down | Compliance Risk | Estimated PPM Saving |
|---|---|---|---|
| Food & Beverage | £3,200–£8,400 | Critical — BRC/SQF | £62k–£190k/yr |
| Manufacturing | £1,800–£5,000 | Medium | £38k–£120k/yr |
| Cold Storage | £4,000–£12,000 | Critical — product loss | £80k–£250k/yr |
| Logistics | £900–£2,200 | Low–Medium | £18k–£55k/yr |
| Aggregate/Mining | £2,500–£7,000 | High — safety | £50k–£160k/yr |
