Planned Preventative Maintenance: A Guide for Businesses

Przemek Dunajski14 min readAberdeen & Aberdeenshire

A blocked gutter is not an expensive problem. The water that gets past it can be.

A slipped slate, an open mortar joint, a leaking valve or a door that no longer closes properly can all look like jobs for another day. In a commercial building, another day can turn into a damaged ceiling, wet stock, an unsafe area, lost trading time or several trades trying to repair the consequences.

Planned preventative maintenance is the habit of dealing with buildings before they force the issue. For businesses, landlords and property managers, that means inspecting the parts of a property most likely to deteriorate, recording what is found, deciding what needs attention now and planning the rest before it becomes urgent.

It is not about replacing perfectly serviceable parts. It is not a promise that nothing will ever break. And it should not become a huge maintenance spreadsheet that nobody uses. Done properly, PPM gives the person responsible for a building something much more useful: fewer surprises.

What is planned preventative maintenance?

Planned preventative maintenance, usually shortened to PPM, is a structured approach to inspecting and maintaining a building at planned intervals rather than waiting for every defect to become a breakdown.

RICS describes planned preventative maintenance as a way of helping property owners and occupiers understand the condition of their built assets and plan the investment needed to keep building elements performing as intended.

The practical idea is straightforward. Look at the building methodically. Find deterioration while there is still time to make a sensible decision. Record it. Prioritise it. Repair or monitor it. That is very different from simply having a contractor’s phone number for emergencies.

PPM versus reactive maintenance

Reactive maintenance starts when something has already failed. PPM starts while there is still a choice.

 Reactive maintenancePlanned preventative maintenance
TriggerA defect or failure is reportedAn inspection, schedule or known maintenance interval
TimingOften urgentUsually planned
BudgetCan be unpredictableCan be forecast more easily
DisruptionOften occurs at the worst timeCan be scheduled around the business
Typical exampleWater is coming through a ceilingRoof defect identified before internal damage

Businesses still need reactive maintenance. A storm can damage a roof that looked fine a week earlier. A pipe can fail unexpectedly. A lock can break. The point of PPM is not to eliminate every emergency, it is to stop preventable defects making up most of the maintenance workload.

Why PPM matters more in a business premises

A defect in a commercial property can cost more than the repair itself. If a room has to close, staff may need to move. If a shop entrance becomes unsafe, customers can be affected. If water reaches electrical equipment, the affected area may need to be isolated. If a leak damages stock, decoration and flooring, one building defect has created several costs.

The Health and Safety Executive requires employers to keep workplace buildings in good repair, and to put dangerous defects right immediately or protect the people at risk.

That duty is set out in the HSE guidance on workplace health, safety and welfare law. PPM does not replace a business’s legal duties. It creates a practical system for noticing defects before they are forgotten.

What should a business PPM programme cover?

There is no honest one size fits all schedule. A granite office in Aberdeen, a modern retail unit, a warehouse and a restaurant do not have the same building fabric or the same consequences if something fails. The schedule should reflect the property, its age, exposure, use, known defects and the importance of each area to the business.

In practice, ten elements account for most of what a programme needs to watch.

ElementWhat deterioration looks likeConsequence if missed
RoofsSlipped slates, failed flashings, blocked outlets, damaged ridges and leadworkWater reaching insulation, ceilings, electrics or stock
Gutters and downpipesOverflowing sections, loose brackets, failed joints, blocked outletsSaturated walls, staining, water discharged over entrances
External walls and masonryOpen mortar joints, cracking, loose harling or render, failed sealantsWater tracking into the building fabric
Doors, windows and joineryDropped doors, failed closers and seals, coating failure, decayAccess, security and draught problems
Plumbing and waterDripping valves, failed sealant, corrosion, unexplained stainingSlow leaks doing more damage than dramatic ones
Electrical systemsRepeated tripping, damaged accessories, water near equipmentIsolation of an area, or worse
Gas and heatingFaults on appliances and heating plantRegulated work needing the correct registered person
Fire safety defectsDamaged fire doors, failed emergency lighting, obstructed escape routesLife safety, directed to a competent person
Internal fabricDamaged stairs and handrails, ceiling damage, water stainingSafety, use and presentation
External areasSteps, ramps, paths, drainage, fences and boundary wallsMarginal defects becoming hazards in winter

Each of those is covered in detail, with photographs of the failure modes, in our commercial property maintenance guide. If the building is domestic rather than commercial, the equivalent list is in our maintenance checklist for homeowners and landlords.

Two of those elements deserve a specific note. Where electrical work is required, Granite Builders uses an NICEIC Approved Contractor. Where gas work is required, we use Gas Safe registered engineers. Those accreditations are held by the contractors and engineers we partner with, not by us as a building firm. The value to a commercial client is access to the correct specialist as part of a coordinated repair, rather than a general builder attempting specialist work.

In Scotland, fire safety duties for most non domestic premises sit under the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006. The Scottish Government publishes non domestic fire safety guidance covering what that means in practice.

A practical PPM schedule for businesses

The useful question is not “how often should every building be inspected?” It is “what can reasonably go wrong here, how quickly could it deteriorate, and what would the consequence be?”

FrequencyUseful focusExamples
OngoingEveryday useLeaks, damaged doors, lighting failures, unsafe flooring, blocked access
Monthly or periodicHigh use areasDoors, sanitary areas, internal fabric, accessible external areas
Quarterly or condition ledBuilding envelopeRainwater goods, known leak areas, external fabric, drainage
Pre winterWeather resilienceRoof, gutters, downpipes, flashings, exposed masonry, external timber
After severe weatherStorm sensitiveRoof coverings, rainwater goods, loose external materials, water ingress
Annual or specialistFormal intervalsItems whose inspection interval is set by law, risk assessment, manufacturer guidance or specialist advice

This is a planning framework, not a statutory timetable. Specialist systems and regulated inspections have their own requirements, and a PPM schedule should sit alongside those obligations rather than replace them.

The four priority levels that make a PPM report useful

A long defect list with no priorities is not a maintenance plan. The person reading it needs to know what to do next.

Priority 1: make safe or act now

Anything presenting an immediate safety risk, serious water ingress, insecure access or major operational problem needs prompt action. A long term maintenance plan is irrelevant if the defect is dangerous today.

Priority 2: repair before it spreads

These are the jobs that are not yet disasters but have a clear route to becoming one. A smaller roof leak, a failed gutter section, an active plumbing leak, a deteriorating external finish or progressing damp all sit here.

Priority 3: programme the repair

The work matters but can be sensibly scheduled. This is where PPM starts giving the business control over timing and budget rather than reacting to whatever failed most recently.

Priority 4: monitor and budget

Some elements are still serviceable but clearly ageing. Recording them now gives the business time to budget for renewal rather than discovering the cost unexpectedly.

The three outcomes of a good inspection

An inspection should not be judged by how many repairs it sells. Sometimes the correct result is that an element is in satisfactory condition and nothing needs doing. Sometimes a repair is needed now, and the scope should be clear. Sometimes the most sensible answer is to monitor deterioration and plan future work.

Those three outcomes keep PPM grounded. Inspect, decide, record. Do not replace things simply because they are old, and do not ignore deterioration simply because it has not failed yet.

What records should a business keep?

You do not need complicated software to improve maintenance records. You need consistency.

A maintenance record that earns its place
  • Site or building, and the location of the defect within it.
  • Date reported or inspected, and photographs of what was found.
  • Description, priority and recommended action.
  • Who is responsible, and the quote or cost.
  • Date completed, with completion photographs.
  • Future recommendation or next review date.

For a single premises that may be a straightforward maintenance log. For a multi site organisation, the same structure makes it possible to compare sites and spot recurring problems.

Photographs matter most where the person approving work is not based at the property. A clear before and after record is far more informative than an invoice that says “repair completed”. You can see how we document finished work on our recent projects.

PPM is also a budgeting tool

The biggest financial advantage of PPM is often not a dramatic claim that every planned repair costs less. It is predictability.

A business that knows a roof section is approaching major repair can plan for it. A property manager who can see repeated gutter failures across several sites can decide whether patching still makes sense. A landlord who knows external decoration will be required next year can budget before the work becomes urgent.

RICS notes that PPM helps clients understand current asset condition and plan necessary investment. That is why a good maintenance record should show more than completed jobs. It should show what is coming.

Why this compounds across multiple sites

PPM becomes more valuable as the number of properties increases. Five sites do not just create five times as many repairs. They create five sets of access arrangements, maintenance histories, staff contacts, budgets and priorities.

A consistent system lets a facilities manager see which properties generate repeated reactive calls, which assets are approaching renewal and where spending is concentrated. It is also where one point of contact for several trades saves a surprising amount of management time. A roof leak that also affects electrics and internal finishes should not require the facilities manager to start from zero with three unrelated contractors.

What PPM does not replace

PPM is useful, but it is not a substitute for every specialist inspection, certificate, risk assessment or statutory duty that applies to a commercial premises. RICS explicitly notes that a PPM survey does not remove the obligations on owners, landlords or tenants for statutory compliance.

That distinction matters. A visual building inspection may identify an obvious concern, but it does not become an electrical inspection, a fire risk assessment, a gas safety check or a specialist structural investigation. A competent maintenance contractor should be willing to say when a different specialist is needed.

How to start PPM without making it complicated

Businesses sometimes avoid planned maintenance because they imagine it requires a large facilities management contract from day one. It does not.

A practical starting point is to identify the buildings, record known recurring problems and establish which parts of each property would cause the greatest disruption if they failed. Then inspect the building envelope, the internal condition and any obvious service related concerns. Grade the findings. Deal with urgent defects. Put the rest into a realistic programme.

For many businesses the first useful PPM plan fits on a few pages, and becomes more detailed as the maintenance history grows. The system should earn its place by making decisions easier.

PPM in Aberdeen: why the building envelope deserves attention

Aberdeen and Aberdeenshire add a local dimension to preventative maintenance. Strong winds, wind driven rain, freezing conditions and exposed coastal locations put repeated pressure on roofs, rainwater goods and external finishes. Older granite buildings bring their own considerations.

A blocked gutter or open joint that might go unnoticed through a dry period becomes much more obvious after repeated North Sea weather. Pre winter checks are therefore particularly useful here. Roof coverings, gutters, downpipes, flashings, external masonry, harling, render and exposed timber all deserve attention before the worst weather rather than after it.

Where the wall itself is traditional granite or rubble stone, the repair method has to suit the existing construction rather than assume it behaves like a modern cavity wall. That is the subject of our guide to granite repair and repointing in Aberdeen. Where maintenance has been deferred long enough that repair is no longer the right answer, it becomes a refurbishment project instead.

Granite Builders is a family run firm and has worked across Aberdeen and Aberdeenshire for more than 20 years. For organisations that need ongoing property maintenance in Aberdeen, the useful part of that local experience is knowing what tends to fail here and looking for it before the next storm finds it first.

How to choose a PPM or maintenance contractor

Five things worth more than the hourly rate
  • Look beyond the rate. For ongoing maintenance, the cheapest isolated visit is not always the lowest cost arrangement. Consider response, reporting, quality of diagnosis and whether recurring defects are actually being resolved.
  • Ask who carries out specialist work. If electrical or gas work may arise, ask exactly who does it and what registration they hold.
  • Expect a clear scope. “Fix leak” is not enough. A useful scope explains what was found, what is proposed, what is included and whether further investigation may be required.
  • Use photographic reporting. Especially valuable for managing agents, landlords and multi site organisations, because the decision maker can see the defect and the completed repair without being on site.
  • Choose a contractor that can handle the follow on work. Many maintenance problems cross trades. The value of a multi trade arrangement is coordination and accountability, not pretending one person can do every specialist job.

Note. This guide is general information about planned preventative maintenance. A PPM programme sits alongside the specialist inspections, risk assessments and statutory duties that apply to a premises and does not replace them. Responsibility for repairs between a commercial landlord and tenant depends on the lease.

Planned preventative maintenance, common questions

PPM stands for planned preventative maintenance. In property management it refers to planned inspection and maintenance intended to identify deterioration and organise repairs before defects develop into more serious failures.

Inspecting and clearing rainwater goods before winter is a simple example. The aim is to keep the system working before blocked or defective gutters contribute to water damage in the wall or the interior.

No. Reactive maintenance responds after a defect or failure occurs. PPM is scheduled or condition led work intended to identify and manage deterioration earlier. Most businesses need both, and a good arrangement covers each.

There is no single interval for an entire commercial building. Frequency should reflect the element, its condition, exposure, use and risk, alongside manufacturer guidance and any specialist or statutory requirements that apply.

No, and any contractor promising that is overselling it. Unexpected failures still happen. PPM reduces avoidable surprises and gives the business a better chance of finding deterioration before it becomes disruptive.

Yes. Recording current condition and likely future work allows repairs and renewals to be planned rather than appearing only as emergency expenditure, which is usually the more expensive way to meet the same cost.

The person or company should be competent for the work involved. Where electrical work is required, Granite Builders uses an NICEIC Approved Contractor. Where gas work is required, it uses Gas Safe registered engineers. Those accreditations belong to the contractors and engineers we partner with.

Yes, although the system can be much simpler than for a large portfolio. Even a basic inspection and maintenance log helps prevent recurring defects being forgotten between one report and the next.

Yes. A consistent schedule and reporting format helps facilities managers compare sites, see recurring failures and plan expenditure across a portfolio rather than treating each building as an isolated problem.

No. A PPM programme sits alongside the specialist inspections, assessments and legal duties applicable to the premises. A visual building inspection does not become an electrical inspection, a fire risk assessment or a gas safety check.

A better way to manage building maintenance

The best PPM programme is not the longest one. It is the one people actually use. It finds the small roof defect before the ceiling is damaged, notices the overflowing gutter before the wall stays wet all winter, and tells the business what is urgent, what can wait and what to budget for next year. If you manage one commercial building or a portfolio, start with the problems that keep recurring.
