For facilities, estates and engineering teams
Planned Preventative Electrical Maintenance in Scotland
Build a practical electrical PPM programme around your assets, operations and priorities. WB Electrical plans scheduled maintenance visits, records findings and helps turn agreed actions into planned work.
From our Larkhall base, we support commercial, industrial and public-sector sites across Glasgow, Lanarkshire and the Central Belt, with wider Scottish programmes considered by agreement.
Defined assets. Risk-led schedules. Clear follow-up.
A programme built around the site
When planned electrical maintenance adds value
PPM is most useful when you need a repeatable way to look after electrical assets rather than waiting for faults. The starting point should be the site, equipment, operating conditions and maintenance history, not a generic annual checklist.
You need a reliable baseline
You are taking on a site, records are incomplete or existing maintenance has grown ad hoc. A baseline review can identify priority systems, information gaps and a sensible first asset scope.
You want fewer avoidable surprises
Distribution equipment, accessories and local supplies are ageing, heavily used or exposed to dust, heat, moisture, vibration or other conditions that can accelerate deterioration.
You manage several sites or shutdowns
Your facilities or engineering team needs planned visits, consistent records and agreed actions across one building, several locations or controlled shutdown windows.

Defined assets and responsibilities
What a PPM programme can include
The maintenance schedule should state which assets, areas and activities are included. For accessible low-voltage electrical systems, the agreed scope can cover distribution equipment, critical supplies, lighting controls, accessories and visible cable or containment condition.
Distribution and electrical condition
Planned checks can cover accessible boards, isolators, protective devices, enclosures, labels and selected circuit or equipment supplies, with deterioration, contamination, damage and recurring issues recorded against the agreed scope.
Condition-led and scheduled activities
Thermal imaging, load observations or specific servicing activities can be coordinated where their method, operating condition, competence and output are defined. Formal inspection and testing remains a separate service even when dates are coordinated.
Defined exclusions and specialist interfaces
High-voltage systems, hazardous-area work, fire and security systems, mechanical plant and manufacturer-controlled equipment are not assumed within a general PPM visit. Responsibilities are confirmed before work is included.
For individual needs, use Thermal Imaging & Condition Monitoring, Electrical Equipment Servicing, Compliance Testing or Backup & Standby Power Systems.
Access, isolation and a repeatable sequence
Plan maintenance around live operations
Good PPM is planned around the people and systems that must keep working. Identify critical loads, permits, restricted areas and suitable isolation windows before the visit so maintenance does not create avoidable disruption.
01
Review records and asset priorities
Use available drawings, previous reports, fault history, manufacturer information and site knowledge to define what needs attention and what information is missing.
02
Agree access, isolations and visit scope
Confirm the site contact, permits, escorts, shutdown windows, working hours and authority for minor repairs or additional work. Phased or out-of-hours attendance can be considered by agreement.
03
Complete, record and refine
Carry out the agreed activities, raise urgent concerns, record limitations and identify follow-up work. Recurring findings and changes to the site can then inform the next visit and future frequency.
An asset that cannot be safely accessed or isolated remains a planning issue to resolve. It should be recorded as a limitation rather than treated as maintained by assumption.

Useful records, not just a tick sheet
Turn each visit into clear maintenance actions
A practical visit record
- Assets, areas and planned activities included in the visit.
- Work completed, settings or parts changed and any supporting records.
- Findings, photographs, limitations and items that could not be accessed.
- Recommended actions, owner or approval route and target where agreed.
The visit record should help the facilities or engineering team understand what was completed, what remains open and what needs a separate quotation, shutdown or specialist attendance.
Priorities should lead to action
- Urgent concern: raised promptly with the nominated site contact and made safe where the agreed authority and conditions allow.
- Planned corrective work: scoped for approval, parts, access and a suitable work window.
- Monitor or review: retained for comparison where condition or trend needs further evidence.
- Separate formal test: routed to the relevant inspection or testing service where a specific certificate or report is required.
Routine PPM observations should not be given EICR classification codes unless an EICR has actually been completed. The maintenance record and any formal inspection report should remain distinct.
Where corrective work is needed, WB can define a separate repair or improvement scope and coordinate it through the wider electrical maintenance service.
Long-term support in operational environments
Experience across working industrial sites
North British Distillery
WB Electrical has supported North British Distillery since 2016 across its Edinburgh distillery and associated West Lothian warehousing sites, delivering planned works, reactive fault finding, compliance activity and electrical infrastructure improvements.
The relevant experience is coordinating electrical work around live operations, access, shutdowns, site controls and clear handover. A new PPM programme would still receive its own asset scope, frequency and reporting requirements.
Supplier assurance
Review WB’s current electrical contractor memberships, management-system certificates and accreditation evidence as part of your supplier assessment.
Practical answers before you plan
Planned electrical maintenance questions
What is planned preventative electrical maintenance?
Planned preventative maintenance, often shortened to PPM, is scheduled work on agreed electrical assets intended to maintain condition, identify developing concerns and organise corrective action. A useful programme defines the assets, activities, frequency, access, reporting and exclusions.
How often should electrical PPM be carried out?
There is no universal annual interval for every asset or premises. Starting frequencies should consider equipment type, use, environment, condition, fault history, manufacturer information, criticality and the consequence of failure, then be reviewed using the results of maintenance and inspections.
Does PPM replace an EICR or other compliance testing?
No. EICR, emergency lighting testing, PAT and other formal inspections have their own purpose, method and documentation. WB can coordinate dates and resulting actions within a wider maintenance programme while keeping those services and records separate.
Can PPM be planned around production or opening hours?
Yes. Visits can be planned around shifts, quieter periods, weekends or shutdowns where the work and availability support them. The proposal should identify access, isolation, critical systems and who can authorise switching, repairs and restart.
Can WB manage planned maintenance across several sites?
Yes. A multi-site programme can use a common reporting and action structure while retaining the different operating conditions, asset priorities, access controls and responsibilities at each location. A baseline or pilot visit can help settle the format before wider rollout.

Tell us about the site and programme
Request a planned maintenance proposal
Tell us what you look after, what information is available and what you want the maintenance programme to achieve. If the asset list or existing records are incomplete, we can identify whether a document review or baseline site visit is the better first step.
Information for your proposal
- Company or organisation, site address and number of locations.
- Building use, operating hours and critical systems or areas.
- Asset lists, drawings, previous reports and known recurring faults, if available.
- Shutdown windows, permits, escorts and access or isolation restrictions.
- Preferred visit pattern, reporting needs and target start date.
Mention any available documents in the quote form. The office will confirm a suitable way to share them. Please do not remove electrical covers to take photographs.
What affects planned maintenance cost?
Asset quantity and complexity, visit frequency, access, working hours, shutdown requirements, specialist attendance, travel and the agreed reporting or remedial scope all affect price. A generic per-site figure can hide important differences.
The next step may be a quotation, a document review or a baseline site visit. Contracted reactive support, formal testing, parts and larger remedials are included only where the proposal states them.
Based in Larkhall, we support suitable planned maintenance programmes across Glasgow, Lanarkshire and the Central Belt. Multi-site and larger requirements elsewhere in Scotland are considered by agreement.
