Planned preventative maintenance (PPM) is the systematic scheduling of inspections, servicing, and repairs designed to keep building assets operational, safe, and compliant before failures occur. Known in the industry as PPM, it is the recognised standard approach in UK facilities management for controlling maintenance costs, meeting statutory obligations, and protecting asset lifespan. Facilities managers who adopt a structured PPM programme shift from reacting to problems to anticipating them. Reactive repairs typically cost three to five times more than planned interventions. That cost gap alone makes the case for a proactive approach. PPM also supports business continuity, ESG targets, and capital expenditure planning in ways that reactive maintenance simply cannot.
What are the essential components of a PPM schedule?
A compliant and functional PPM schedule is built on five core steps. Each step depends on the one before it, so skipping ahead creates gaps that surface later as compliance failures or missed inspections.
- Build an accurate asset register. An accurate asset register is non-negotiable. Without a complete inventory of every piece of plant, equipment, and building fabric, you cannot schedule what you do not know exists.
- Map assets to SFG20 maintenance frequencies. SFG20 is the UK’s recognised benchmark for maintenance task specifications and intervals. Each asset category carries defined service frequencies that your schedule must reflect.
- Separate statutory tasks from best-practice tasks. Statutory tasks such as gas safety inspections (CP12), LOLER lift examinations, and fire safety checks carry legal obligations. They must be treated as non-negotiable and scheduled with zero tolerance for deferral.
- Assign named contractors and document responsibilities. Every task needs a named owner, whether an in-house engineer or an external contractor. Accountability without documentation is unenforceable.
- Review the schedule annually, or after condition surveys. PPM schedules must be living documents, reviewed to reflect new assets, changed usage patterns, and updated standards.
The five-step process applies equally to a single commercial office and a multi-site education estate. The complexity scales, but the structure does not change.
Pro Tip: Assign a named schedule owner at the outset. A schedule without a named owner will drift. The owner is responsible for triggering reviews, chasing evidence, and keeping the register current.
Why does SFG20 compliance matter for your PPM programme?
SFG20 is the industry-standard maintenance specification published by BESA (the Building Engineering Services Association). It defines the tasks, frequencies, and skill levels required to maintain building services assets across every major category, from HVAC plant to electrical distribution boards. Compliance with SFG20 gives facilities managers a defensible, auditable basis for their maintenance decisions.
The practical challenge is that SFG20 is not static. The standard receives up to 700 updates per year, covering task revisions, new asset categories, and frequency changes. That volume of change means a manually maintained schedule becomes outdated rapidly. A schedule built on last year’s SFG20 version may already contain incorrect task frequencies or missing requirements.
Schedule drift is the term for this gradual misalignment between a live building and its maintenance programme. Schedule drift leads to mismatches between operational maintenance and current SFG20 standards. The consequences range from failed audits to uninsured equipment and, in serious cases, regulatory enforcement.
The solution is asset-level mapping combined with live integration. Computer-Aided Facilities Management (CAFM) systems that connect directly to the SFG20 API update task specifications automatically as the standard changes. CAFM systems with real-time SFG20 API integration are critical for avoiding schedule drift and maintaining audit-ready compliance evidence. Manual static imports cannot achieve the same result.
Pro Tip: When evaluating CAFM platforms, ask specifically whether SFG20 integration is live API-based or a periodic manual import. The difference determines whether your schedule stays current or silently falls behind.
Audit readiness and risk mitigation
Audit readiness is a direct product of SFG20 compliance. When every asset has a defined task, a scheduled frequency, and a documented completion record, your maintenance programme can withstand scrutiny from insurers, regulators, and building owners. Without that structure, subcontractor-managed assets have no auditable PPM compliance evidence, which creates significant liability exposure.
How do statutory duties shape PPM requirements?
Statutory maintenance tasks are legally mandated. They are not discretionary, and they cannot be deferred without creating legal and safety risk. Facilities managers must treat these tasks as the fixed backbone of any PPM programme, around which best-practice tasks are then scheduled.
The core statutory tasks in UK facilities management include:
- Gas safety inspections (CP12). Annual inspections of gas appliances and flues by a Gas Safe registered engineer. Required under the Gas Safety (Installation and Use) Regulations 1998.
- LOLER examinations. Thorough examinations of lifting equipment, including passenger lifts, under the Lifting Operations and Lifting Equipment Regulations 1998. Typically required every six months for passenger-carrying equipment.
- Fire safety inspections. Required under the Regulatory Reform (Fire Safety) Order 2005. Includes fire alarm testing, emergency lighting checks, and fire suppression system servicing.
- Water hygiene management (ACoP L8). Legionella risk assessments and control measures under the Approved Code of Practice L8. Failure to comply carries criminal liability.
- Electrical installation condition reports (EICR). Required at defined intervals under BS 7671 to confirm electrical installations remain safe.
Statutory tasks such as CP12 and LOLER inspections must never be deferred. Their legal status demands rigorous scheduling and documented evidence. The Building Safety Act 2022 has further tightened accountability for building owners and responsible persons, making documented compliance records more critical than ever.
Failing a statutory task is not simply an operational problem. It can result in prohibition notices, prosecution, invalidated insurance, and, in the most serious cases, criminal liability for the responsible person. The consequences of failing statutory PPM tasks extend well beyond the cost of the missed inspection.
What challenges do facilities managers face when implementing PPM?
Implementing a PPM programme is straightforward in principle. Sustaining it across a complex estate, with multiple contractors and changing asset conditions, is where most programmes encounter difficulty.
The most common challenges are:
- Schedule drift. Without a named owner and a defined review cycle, schedules fall out of alignment with current standards and actual asset conditions.
- Inaccurate asset registers. Incomplete or outdated registers cause missed compliance tasks, creating operational risk that is invisible until an audit or failure exposes it.
- Subcontractor evidence gaps. Third-party contractors may complete work without capturing asset-level records. Without that evidence, the task effectively did not happen from a compliance perspective.
- Manual schedule management. Spreadsheet-based schedules cannot keep pace with SFG20 updates or flag overdue tasks automatically.
Technology addresses each of these challenges directly. CAFM platforms automate task scheduling, generate work orders, and capture completion evidence against individual assets. Facilities management experts highlight PPM as a tool to shift from chaotic reactive environments to controlled, compliant operations. That shift requires the right systems, not just the right intentions.
Pro Tip: Require all subcontractors to submit completion evidence at asset level, not just a job-level sign-off. A single sign-off for a multi-asset visit tells you nothing about which assets were actually serviced.
For facilities managers exploring the broader market for integrated facilities management, understanding how PPM sits within a wider service framework is a useful starting point.
How can facilities managers build a PPM programme for long-term success?
A PPM programme that delivers long-term value requires more than a schedule. It requires governance, ownership, and a commitment to continuous improvement.
- Start with the asset register. Conduct a full building survey to capture every asset, its location, condition, and maintenance history. This is the foundation on which everything else is built.
- Map tasks to SFG20 and statutory requirements. Use SFG20 as the baseline for task specifications and frequencies. Layer statutory requirements on top, clearly flagged as non-deferrable.
- Create the schedule and assign ownership. Build the schedule in a CAFM system where possible. Assign a named owner for the overall programme and named contractors for each task category.
- Incorporate condition monitoring. Fixed-frequency schedules are a starting point, not an endpoint. Condition monitoring data, from vibration analysis on pumps to thermal imaging on electrical panels, allows you to adjust frequencies based on actual asset health rather than calendar intervals alone.
- Align PPM with organisational goals. Regular servicing prevents premature wear and reduces carbon footprint through efficient equipment operation. That alignment with ESG targets makes PPM a board-level conversation, not just a maintenance department concern.
- Review and update annually. Adapting schedules to changing building usage patterns maintains safety, compliance, and budget balance. A schedule that does not change is a schedule that is falling behind.
Vendor management is the final piece. Set clear service level agreements with contractors, require evidence capture at asset level, and review contractor performance as part of the annual schedule review. Transparent reporting from your maintenance partner is not optional. It is the mechanism by which you verify that your programme is delivering what it promises.
Pro Tip: Use your PPM data to inform CapEx planning. A well-maintained asset register, with condition ratings and service histories, tells you which assets are approaching end of life and when replacement budgets need to be allocated.
Key takeaways
A well-governed PPM programme is the single most effective way to control maintenance costs, meet statutory obligations, and extend the operational life of building assets.

Why PPM is the most undervalued tool in facilities management
I have worked alongside facilities managers across commercial offices, healthcare sites, and education estates, and the pattern is consistent. The buildings with the fewest crises are not the ones with the biggest maintenance budgets. They are the ones with the most disciplined PPM programmes.
The blind spot I see most often is treating the asset register as a one-time task. Managers invest significant effort in the initial survey, then allow the register to drift as assets are added, replaced, or decommissioned without being recorded. Within two or three years, the schedule is managing a building that no longer exists. The physical estate has moved on, but the paperwork has not.
The second blind spot is conflating activity with compliance. A contractor visiting site and completing a job sheet is not the same as a compliant, auditable maintenance record at asset level. The distinction matters enormously when an insurer or regulator asks for evidence. I have seen facilities teams genuinely surprised to discover that years of contractor visits produced no usable compliance evidence because the documentation was captured at job level rather than asset level.
The practical fix is straightforward: require asset-level evidence as a contractual condition of every maintenance visit, and review that evidence quarterly rather than waiting for an annual audit. PPM is not a set-and-forget system. It is a management discipline that rewards consistent attention.

FAQ
What does PPM mean in facilities management?
PPM stands for planned preventative maintenance. It is a proactive, scheduled approach to maintaining building assets that prevents failures, reduces costs, and keeps buildings compliant with UK statutory requirements.
What is SFG20 and why does it matter for PPM?
SFG20 is the UK’s recognised standard for building services maintenance tasks and frequencies, published by BESA. It provides the benchmark task specifications that facilities managers use to build compliant PPM schedules.
Which statutory tasks must be included in a PPM schedule?
Gas safety inspections (CP12), LOLER lift examinations, fire safety checks, water hygiene management under ACoP L8, and electrical installation condition reports (EICR) are all legally mandated and must be included with zero tolerance for deferral.
How often should a PPM schedule be reviewed?
A PPM schedule should be reviewed at least annually, or after any significant asset condition survey or change in building usage. Schedules that are not reviewed regularly suffer from drift and fall out of alignment with current standards.
What is the difference between planned and reactive maintenance?
Planned maintenance is scheduled in advance to prevent failures, while reactive maintenance addresses faults after they occur. Reactive repairs typically cost three to five times more than planned interventions and cause greater operational disruption.
