How a PPM schedule keeps business equipment ready for work
When equipment or building systems fail, the cost is not just the repair: work can be disrupted and safety may be affected. Planned preventative maintenance gives you a schedule for checking and servicing assets before faults become urgent.

Planned preventative maintenance, usually shortened to PPM, is maintenance arranged in advance to keep equipment and buildings in a suitable condition. Tasks may include inspections, servicing, testing or calibration, scheduled according to the asset, its use and the risks of failure. A schedule can make work and records easier to manage, but it cannot guarantee that nothing will break. The useful question is whether your plan covers the right assets, at appropriate intervals, and gives people a safe way to complete and record each task.
What counts as planned preventative maintenance?
PPM is a set of maintenance tasks planned before a fault forces an urgent repair. Depending on the asset, those tasks might be a visual inspection, cleaning, lubrication, a service, a functional test or calibration. It can apply to building systems as well as work equipment.
PPM is not the same as a statutory examination, and a routine service does not automatically satisfy a separate legal inspection requirement. For work equipment, the HSE says PUWER requires equipment to be maintained in an efficient state, efficient working order and good repair. The right maintenance arrangements depend on the equipment and the risks around its use.
Which assets and tasks belong on the schedule?
Start with an asset list: the equipment, systems and building elements that matter to your operation. Include enough detail to identify each item and its location, such as a plant-room ventilation unit or a workshop machine. Then decide what work is needed and why.
Useful factors include the manufacturer’s maintenance instructions, operating hours, working conditions, known faults, and what could happen if the asset failed. Prioritise equipment whose failure could create a safety risk, stop a critical operation or damage other assets. The UK government’s facilities management standard calls for an asset register and forward maintenance planning.
For each task, record its frequency, who is responsible, any required competence or parts, how the work can be done safely, and what evidence should be kept. Avoid copying a generic interval without checking that it fits the asset and site. If your premises include lifting equipment, planned servicing does not replace any applicable thorough examination; the HSE explains how maintenance and thorough examination differ.
How does PPM compare with reactive maintenance?
PPM schedules work in advance, while reactive maintenance begins after someone reports a defect or breakdown. Planned work may be easier to coordinate around operating hours and can help identify deterioration before it causes a more serious disruption. Reactive repairs remain necessary because a schedule cannot eliminate unexpected faults.
The choice is not simply “planned is always better.” A low-impact item may be cheaper to repair when it fails, while a critical asset may justify regular inspection or servicing because failure would have greater consequences. Compare the task cost and disruption with the risk and potential impact of a breakdown. Keep a reactive repair route in place even when PPM is established.
How can you put a workable schedule into practice?
Create a task list from the asset register, then assign each task an interval, owner and record. Make sure staff know how to report defects between scheduled visits. Before work begins, coordinate access, isolation and communication with anyone who could be affected. The HSE warns that maintenance must be properly planned and carried out safely, and says work equipment maintenance should be done by people competent for the task.
You can manage the schedule in a spreadsheet or use maintenance software to organise tasks and records. The tool matters less than keeping the asset details, due dates, work instructions and completion evidence accurate.

How do you check whether the plan is working?
Review whether tasks were completed when due, whether defects were found, and whether breakdowns or repeat repairs continue. Check that records identify the asset, work carried out, date, findings and any follow-up action. An overdue task should be assessed for its risk and rescheduled deliberately, not simply left to roll forward.
Use the evidence to adjust priorities and intervals when equipment condition, use or site arrangements change. A useful PPM plan is not just a calendar of visits: it links maintenance tasks to assets, risks, competent people and follow-up actions.
Frequently asked questions
Is planned preventative maintenance a legal requirement in the UK?
There is no single rule requiring every business to use a document called a PPM schedule. However, specific duties can require you to maintain work equipment in a safe condition, inspect it where risks or deterioration make that necessary, and carry out certain examinations. Under PUWER, employers must maintain work equipment in an efficient state, efficient working order and good repair. Check the rules that apply to each asset and workplace.
How often should planned maintenance be carried out?
There is no universal interval for every asset. Set the frequency using the manufacturer’s instructions, how often and in what conditions the equipment is used, its condition, and the consequences of failure. Where a specific legal inspection or examination applies, follow its requirements. Record why you chose the interval and review it if operating conditions, faults or asset condition change.
Does PPM mean equipment will not break down?
No. Regular checks and servicing can identify some wear or developing faults, but they cannot predict or prevent every failure. Unexpected breakdowns may still happen, so keep a clear process for reporting faults, assessing immediate risks and arranging repairs. Reviewing breakdown records alongside completed PPM tasks can help you spot recurring problems or a schedule that needs adjustment.
What is the difference between PPM and reactive maintenance?
PPM is arranged in advance, often at set intervals or in response to an inspection or condition. Reactive maintenance starts after a fault or failure is reported. Most workplaces need both: planned work can help manage foreseeable maintenance needs, while a response process deals with unplanned faults. The balance depends on the asset, the likelihood and consequences of failure, and the cost of planned work.
