Summary
Planned Preventative Maintenance (PPM) is one of the most effective ways to keep buildings safe, compliant and operating efficiently. Rather than waiting for equipment to fail, PPM focuses on regular inspections and scheduled maintenance to prevent costly breakdowns before they happen. In this guide, we explain what PPM is, why it's important and how building managers can develop an effective maintenance strategy.
Introduction
Every building relies on hundreds of assets working together.
Heating systems.
Air conditioning.
Fire alarms.
Emergency lighting.
Lifts.
Electrical systems.
Water services.
Like any equipment, these assets naturally deteriorate over time.
The question is simple:
Do you wait for something to fail, or do you prevent the problem before it happens?
That's exactly what Planned Preventative Maintenance (PPM) is designed to achieve.
Rather than reacting to unexpected breakdowns, PPM helps building owners and facilities managers keep assets operating safely, efficiently and reliably through regular planned maintenance.
What Is Planned Preventative Maintenance?
Planned Preventative Maintenance (PPM) is the process of carrying out scheduled inspections, servicing and maintenance on building assets before they develop faults or fail.
Instead of waiting until something stops working, maintenance is carried out at planned intervals based on:
- Manufacturer recommendations
- Legal requirements
- Asset condition
- Usage levels
- Risk assessments
The objective is simple:
Prevent problems rather than react to them.
Why Is PPM Important?
Waiting until equipment fails often results in:
- Emergency call-outs
- Unexpected repair costs
- Operational disruption
- Safety risks
- Reduced asset lifespan
PPM helps minimise these risks while delivering several long-term benefits.
Reduced Costs
Preventative maintenance is usually far less expensive than emergency repairs.
Replacing a worn component during a scheduled visit is often significantly cheaper than replacing an entire failed system.
Improved Compliance
Many building systems require regular inspection to help organisations meet their legal and regulatory responsibilities.
Examples include:
- Fire alarm testing
- Emergency lighting inspections
- Lift servicing
- Fixed electrical testing
- HVAC maintenance
Keeping planned maintenance up to date also creates a clear audit trail that can be invaluable during inspections.
Longer Asset Life
Regular servicing helps equipment perform as intended for longer.
This reduces the frequency of major repairs and delays costly replacement projects.
Less Disruption
Unexpected failures rarely happen at convenient times.
PPM allows maintenance to be planned around building operations, reducing disruption for occupants and facilities teams.
Common Examples of Planned Preventative Maintenance
Most commercial buildings already carry out some form of PPM.
Typical examples include:
- Fire alarm servicing
- Emergency lighting testing
- Boiler servicing
- HVAC inspections
- Lift maintenance
- Water hygiene inspections
- Sprinkler system testing
- Electrical inspections
- Generator servicing
- Roof inspections
The frequency of each activity depends on legal requirements, manufacturer guidance and the criticality of the asset.
Reactive Maintenance vs Planned Preventative Maintenance
Reactive maintenance and Planned Preventative Maintenance (PPM) both play an important role in building management, but they take very different approaches.
Reactive maintenance involves repairing or replacing equipment after it has failed. While this approach is sometimes unavoidable, it often results in unexpected downtime, higher repair costs and greater disruption to building occupants. Emergency call outs can also place additional pressure on maintenance teams and budgets.
Planned Preventative Maintenance, on the other hand, focuses on preventing failures before they occur. Maintenance tasks are scheduled in advance based on manufacturer recommendations, legal requirements or the condition of an asset. This proactive approach helps reduce unexpected breakdowns, improves reliability and often lowers long-term maintenance costs.
In reality, most organisations need a combination of both. No matter how effective a PPM programme is, unexpected issues can still arise. However, by carrying out regular planned maintenance, building managers can significantly reduce the number of emergency repairs, minimise disruption and keep their buildings operating safely and efficiently.
Building an Effective PPM Strategy
A successful Planned Preventative Maintenance programme begins with understanding your building and its assets.
Key steps include:
1. Create an Asset Register
Know exactly what assets are within your building.
Record information such as:
- Asset type
- Manufacturer
- Installation date
- Warranty information
- Service history
- Location
2. Prioritise Critical Assets
Not every asset carries the same level of risk.
Critical life safety systems should always receive the highest priority.
3. Schedule Maintenance
Develop a maintenance calendar based on:
- Manufacturer recommendations
- Statutory requirements
- Operational needs
4. Keep Accurate Records
Every inspection, repair and service should be recorded.
Accurate maintenance records help demonstrate compliance, support future planning and provide valuable insight into asset performance.
5. Review Regularly
Buildings evolve over time.
Maintenance schedules should evolve with them.
Review maintenance programmes regularly to ensure they remain effective.
Common PPM Mistakes
Even organisations with maintenance programmes can encounter problems.
Common mistakes include:
- Relying on spreadsheets
- Missing scheduled inspections
- Incomplete maintenance records
- Not updating asset information
- Poor visibility across multiple buildings
- Focusing only on reactive repairs
Addressing these issues can significantly improve the effectiveness of a maintenance strategy.
How Technology Supports Planned Preventative Maintenance
As buildings become more complex, managing maintenance manually becomes increasingly difficult.
Digital maintenance platforms help organisations:
- Schedule inspections automatically
- Record completed works
- Store maintenance history
- Monitor compliance
- Generate reports
- Track asset performance
- Receive maintenance reminders
This reduces administration while improving visibility across an entire property portfolio.
How Liaison Maintain Supports PPM
At Liaison, we believe planned maintenance should be simple, proactive and easy to manage.
Maintain helps building owners and facilities managers organise Planned Preventative Maintenance through one central platform.
With Maintain, organisations can:
- Create maintenance schedules
- Manage planned and reactive maintenance
- Record inspections and completed works
- Store maintenance history
- Monitor compliance activities
- Keep asset information connected throughout the building lifecycle
Combined with View, which provides instant access to drawings, O&M manuals and asset documentation, building managers have everything they need to manage buildings more effectively from one connected platform.
Looking Ahead
Buildings are becoming smarter.
Occupiers expect higher standards.
Compliance requirements continue to evolve.
Planned Preventative Maintenance is no longer simply about fixing equipment.
It's about protecting assets, reducing risk, improving sustainability and ensuring buildings continue performing as intended throughout their entire lifecycle.
Organisations that adopt a proactive maintenance strategy today will be better prepared for tomorrow.
Conclusion
Waiting for equipment to fail is rarely the most efficient or cost effective approach.
Planned Preventative Maintenance helps organisations stay ahead of problems, improve safety, extend asset life and reduce unexpected costs.
With accurate information, consistent maintenance schedules and the right digital tools, building managers can move from reacting to problems to preventing them altogether.
Because the best maintenance issue is often the one that never happens.
