The Direct Answer

Planned preventative maintenance, often called PPM, is the routine inspection, servicing and repair of commercial building assets before they fail. In 2026, facilities teams should use PPM to monitor roofs, drainage, plumbing, HVAC, ventilation, electrical systems, fire doors, fire stopping, lighting, decoration, external fabric and high-use areas.

The goal is simple:

Find the issue before it becomes an emergency repair.

For commercial buildings, planned maintenance helps reduce disruption, protect compliance, control budgets, extend asset life and keep workplaces safe, usable and presentable.

Why Planned Maintenance Matters More in 2026

Commercial buildings are under more pressure than ever.

Facilities managers, landlords and property owners are dealing with:

• ageing buildings

• higher service expectations

• rising repair costs

• tighter compliance duties

• energy efficiency pressure

• tenant expectations

• sustainability targets

• live-site disruption risks

• greater need for maintenance records

In this environment, reactive repairs are not enough.

Waiting for something to fail usually means higher cost, more disruption and less control over timing.

Planned preventative maintenance gives building owners a better understanding of condition, risk and future investment.

PPM vs Reactive Repairs: The Practical Difference

Reactive Repairs

Reactive repairs happen after something has already gone wrong.

Examples include:

• a roof leak during heavy rain

• blocked toilets during the working day

• failed emergency lighting

• broken fire door closers

• electrical faults

• heating breakdowns

• drainage smells

• damaged flooring

• water ingress

• failed ventilation

Reactive repairs are sometimes unavoidable, but they are usually more disruptive.

Planned Preventative Maintenance

PPM is scheduled before failure.

Examples include:

• roof inspections before winter

• gutter and drainage checks

• HVAC servicing

• electrical inspections

• fire door checks

• emergency lighting testing

• plumbing reviews

• fabric repairs

• repainting high-use areas

• checking repeated defects

PPM does not eliminate every emergency, but it reduces the likelihood of preventable disruption.

Why Facilities Teams Are Prioritising PPM

Planned maintenance is becoming more important because commercial buildings are no longer judged only by appearance.

They are judged by:

• how reliably they operate

• how safe they are

• how comfortable they feel

• how efficiently they use energy

• how easy they are to maintain

• how well risks are documented

• how quickly issues are resolved

A building with repeated leaks, failed toilets, poor ventilation, damaged doors or unresolved fire safety defects can quickly become difficult to manage.

For landlords, this can affect tenant satisfaction.

For businesses, it can affect staff experience.

For schools, hospitality venues and public-facing sites, it can disrupt daily operations immediately.

The Commercial Building PPM Priority Map

Not every maintenance task carries the same risk.

A useful way to plan PPM is to group building assets by how quickly failure would affect people, safety or operation.

High-Disruption Assets

These should be checked regularly:

• toilets

• drains

• heating

• ventilation

• electrical systems

• fire doors

• emergency lighting

• roof coverings

• gutters

• water systems

High-Visibility Assets

These affect how the building is perceived:

• reception areas

• corridors

• decoration

• flooring

• doors

• meeting rooms

• staff kitchens

• washrooms

• external entrances

High-Risk Assets

These affect safety, compliance or business continuity:

• fire stopping

• fire doors

• emergency routes

• electrical infrastructure

• roof leaks near services

• plant rooms

• access routes

• damaged external fabric

The best PPM schedules cover all three categories.

1. Roofs, Gutters and External Fabric

Roof defects are one of the easiest maintenance issues to ignore until they become urgent.

A small roof defect can become:

• water ingress

• stained ceilings

• damaged electrics

• mould

• failed decorations

• tenant complaints

• disruption to occupied areas

• expensive emergency callouts

PPM checks should include:

• roof coverings

• flat roof ponding

• flashing

• gutters

• downpipes

• rooflights

• parapets

• plant penetrations

• water staining

• blocked outlets

• external cracks

• damaged pointing

• signs of water ingress

Drone surveys can be useful for roof and high-level inspections where access is difficult or disruptive.

2. Plumbing, Drainage and Toilets

Plumbing and drainage failures can disrupt a building very quickly.

In commercial settings, toilets, sinks, staff kitchens and drains are used heavily every day.

PPM checks should include:

• toilet flush systems

• taps and basins

• leaks

• slow drainage

• recurring blockages

• bad smells

• inspection chambers

• gullies

• waste pipe condition

• staff kitchens and tea points

• plant-room pipework

• water stains

• damaged seals

The aim is to spot patterns.

If the same toilet, drain or sink blocks repeatedly, the issue may need investigation rather than another quick fix.

3. HVAC, Ventilation and Comfort

Heating, cooling and ventilation directly affect building users.

Poor HVAC maintenance can lead to:

• uncomfortable rooms

• complaints

• higher energy use

• poor airflow

• noisy plant

• overheating

• cold areas

• stuffy meeting rooms

• condensation

• mould risk

PPM should review:

• filters

• ventilation performance

• plant condition

• heating and cooling operation

• controls

• zoning

• air movement

• noisy equipment

• service history

• seasonal performance

• meeting rooms and enclosed spaces

This is especially important in offices using hybrid working patterns, because occupancy may vary throughout the week.

4. Electrical Systems and Lighting

Electrical issues can affect safety, productivity and compliance.

A planned maintenance schedule should include:

• lighting condition

• emergency lighting

• socket condition

• distribution boards

• visual checks for damage

• high-use areas

• plant-room power

• meeting room power

• kitchen and tea point power

• external lighting

• lighting controls

• repeated faults

Modern commercial buildings use more technology than ever. Meeting rooms, access control, screens, chargers, staff kitchens and flexible work areas all place demands on electrical systems.

PPM helps identify where the building is no longer supporting how people use it.

5. Fire Doors and Fire Stopping

Fire doors and fire stopping should never be left to chance.

In busy buildings, fire doors can deteriorate through daily use.

Common problems include:

• doors not closing fully

• damaged seals

• damaged frames

• broken closers

• excessive gaps

• loose hinges

• missing signage

• impact damage

• doors being wedged open

Fire stopping can also be affected when new services are installed or altered.

PPM should include regular checks of:

• fire door condition

• door closers

• intumescent seals

• smoke seals

• frames

• gaps

• signage

• service penetrations

• risers

• ceiling voids

• compartment lines

6. Decoration, Flooring and High-Use Areas

Not all maintenance is hidden behind ceilings or inside plant rooms.

High-use finishes matter too.

Poor condition in entrances, corridors, stairwells, toilets, reception areas and meeting rooms can make a building feel neglected.

PPM should monitor:

• scuffed walls

• damaged plaster

• cracked tiles

• worn flooring

• loose thresholds

• damaged skirting

• stained ceilings

• peeling paint

• damaged doors

• worn reception areas

• trip hazards

• water-damaged finishes

Planned decoration and surface repairs can help protect building condition and improve how the site feels to staff, visitors, tenants and clients.

7. Reception, Kitchens and Welfare Areas

Facilities teams should not overlook everyday spaces.

Reception areas, staff kitchens, tea points and welfare spaces are used constantly and can deteriorate quickly.

PPM checks should include:

• reception flooring

• access control

• lighting

• desk power

• kitchen plumbing

• appliances

• ventilation

• waste areas

• seating

• decoration

• storage

• door condition

• cleaning access

These spaces affect first impressions and daily staff experience.

How Often Should PPM Be Carried Out?

There is no single schedule that works for every commercial building.

Frequency depends on:

• building age

• use

• occupancy

• sector

• condition

• compliance requirements

• previous defects

• weather exposure

• tenant expectations

• asset importance

However, facilities teams can use a simple structure.

Weekly or Monthly Checks

Useful for:

• toilets

• leaks

• lighting defects

• blocked drains

• fire door visibility

• high-use areas

• visible damage

• waste areas

Quarterly Checks

Useful for:

• gutters

• roof condition

• HVAC performance

• plumbing issues

• drainage patterns

• emergency routes

• decoration wear

• door condition

Six-Monthly or Annual Reviews

Useful for:

• roof surveys

• planned decoration

• larger fabric repairs

• energy efficiency upgrades

• fire door programmes

• refurbishment planning

• capital expenditure forecasting

The right schedule should be based on risk and use, not guesswork.

PPM and Compliance: Why Records Matter

Good planned maintenance is not only about doing the work.

It is also about keeping evidence.

Facilities teams should keep records of:

• inspection dates

• defects found

• actions taken

• contractor reports

• photos

• recurring problems

• compliance checks

• certificates where relevant

• repairs completed

• outstanding items

• planned follow-up works

Good records help with budgeting, audits, tenant conversations, insurance queries, compliance reviews and future refurbishment planning.

They also help identify patterns.

If the same area keeps failing, the building may need a deeper repair rather than repeated small fixes.

PPM and Energy Performance

Planned maintenance also supports energy efficiency.

Poorly maintained buildings often waste energy through:

• old lighting

• poor controls

• inefficient HVAC

• blocked filters

• leaking roofs

• draughts

• poor insulation

• badly zoned systems

• neglected plant

With energy performance and sustainability becoming more important across commercial property, PPM should link to wider building improvement planning.
