Introduction
Every commercial building requires maintenance.
From lighting and electrical installations to plumbing, doors, heating systems and building fabric, individual assets need attention throughout their working life.
When something breaks, the immediate priority is usually to restore functionality. However, waiting for problems to occur before taking action can expose businesses to avoidable disruption, higher repair costs and potential safety risks.
This is why understanding the difference between planned and reactive maintenance is important.
A balanced maintenance strategy considers both approaches and determines which is appropriate for different assets, systems and operational circumstances.
What is planned maintenance?
Planned maintenance involves organising maintenance activities in advance rather than waiting for a fault to occur.
Activities may be scheduled according to:
Manufacturer recommendations.
Asset condition.
Usage and operating hours.
Risk assessments.
Inspection findings.
Relevant legal and regulatory requirements.
Maintenance history.
For example, a business may schedule inspections of certain equipment, routine servicing of building systems and periodic checks of doors, fixtures and fittings.
The objective is to identify deterioration, address foreseeable issues and maintain assets in an appropriate condition.
Types of planned maintenance
Preventive maintenance
Activities undertaken at predetermined intervals or according to defined usage criteria to reduce the likelihood of equipment failure.
Condition-based maintenance
Maintenance triggered by information about the actual condition of an asset, such as inspection findings or monitoring data.
Predictive maintenance
Where suitable technology and information are available, trends and measurements can be used to estimate when intervention may be required.
These approaches are not interchangeable. The appropriate method depends on the asset, the risks involved and the quality of available information.
What is reactive maintenance?
Reactive maintenance takes place after a defect, fault or failure has been identified.
Examples include:
Repairing a leaking pipe.
Replacing a failed light fitting.
Responding to a malfunctioning door.
Repairing damaged flooring.
Investigating an unexpected equipment failure.
Reactive maintenance is necessary even in buildings with good preventive maintenance arrangements.
Not every failure can be predicted, and not every asset requires the same level of planned intervention.
The important consideration is whether the organisation has appropriate procedures to report, assess, prioritise and resolve faults.

Neither approach should be viewed in isolation.
An effective strategy uses planned activities where justified and maintains a responsive process for unexpected problems.
Why relying entirely on reactive maintenance can be risky
1. Operational disruption
A failed asset can affect the way a business operates.
A plumbing failure may make a washroom unavailable. A malfunctioning access system may affect security arrangements. A heating failure may affect working conditions.
The operational impact can be greater than the cost of the physical repair.
2. Unpredictable expenditure
Emergency repairs may involve additional labour, specialist attendance or replacement parts.
The total cost may also include lost productivity, temporary arrangements and disruption to customers.
3. Safety implications
Some equipment and building components have safety-critical features.
If deterioration could create a risk, appropriate inspection and maintenance arrangements are essential.
The HSE states that employers must have arrangements to ensure necessary inspections of safety-critical features of work equipment.
4. Limited visibility of asset condition
When maintenance records are incomplete, organisations may struggle to understand which assets are deteriorating or repeatedly failing.
This makes it harder to prioritise investment and plan future expenditure.
How to develop a practical maintenance strategy
Step 1: Create an asset register
Record relevant information about the building and its equipment.
An asset register might include:
Asset description.
Location.
Manufacturer and model.
Installation date, where known.
Maintenance requirements.
Relevant inspection history.
Criticality and operational importance.
Responsible party.
Step 2: Prioritise assets according to risk
Not every asset requires the same maintenance approach.
Consider:
Potential consequences of failure.
Health and safety implications.
Legal or statutory inspection requirements.
Business continuity impact.
Replacement cost.
Availability of alternatives.
This helps determine where planned intervention is most important.
Step 3: Establish maintenance schedules
Use suitable information from manufacturers, competent specialists and applicable regulations to determine appropriate activities and frequencies.
Do not assume that a generic annual inspection is sufficient for every asset.
Some equipment requires more frequent attention, while other activities may be condition-based.
Step 4: Establish reactive maintenance procedures
Make it easy for building users to report problems.
A maintenance reporting process should capture:
Site and exact location.
Description of the fault.
Date and time reported.
Potential safety implications.
Operational impact.
Priority classification.
Assigned contractor or responsible person.
Actions taken and completion details.
Step 5: Monitor recurring problems
Repeated faults may indicate an underlying issue rather than isolated incidents.
Maintenance records can help identify patterns, such as repeated leaks, recurring electrical problems or equipment that frequently requires repair.
These findings should inform future maintenance decisions.
What should businesses measure?
Useful maintenance indicators may include:
Planned maintenance completion.
Outstanding work orders.
Response and completion times.
Repeat faults.
Maintenance expenditure.
Equipment downtime.
Safety-related defects.
Outstanding inspection actions.
These indicators should be interpreted in context. For example, a high volume of completed work orders does not automatically mean that maintenance performance is good.
How Xcell can support maintenance coordination
Xcell Facilities Management can discuss maintenance requirements and the coordination of appropriate building support services.
Depending on the agreed scope, available resources and relevant technical competence, this may include maintenance scheduling, inspections, minor repairs and coordination with specialist contractors.
The objective is to help clients establish clearer visibility of maintenance requirements and appropriate responsibilities.
Specialist and regulated maintenance activities must be undertaken by appropriately qualified and authorised personnel.
Final thoughts
Planned maintenance and reactive maintenance are complementary parts of building management.
Planned intervention helps organisations address foreseeable requirements, while reactive arrangements provide a response when unexpected issues occur.
The right balance depends on the building, the assets, operational priorities and the consequences of failure.
