Why scheduled maintenance pays
Electrical faults in commercial buildings rarely appear without warning. A termination loosens through thermal cycling, resistance rises, heat builds, and the connection degrades further. That process takes months.
Caught early it is a torque check during a scheduled visit. Caught late it is a failed breaker, a damaged panel, and a building that cannot trade until it is fixed.
- Downtime avoided is worth more than the inspection costs
- Repairs happen on your schedule, not during trading hours
- Insurers increasingly ask for evidence of electrical maintenance
- Documented condition supports lease and compliance obligations
- Budget becomes predictable instead of reactive
Thermal imaging, and what it finds
A thermal camera reads surface temperature, which makes electrical problems visible before they are audible or visible to the eye. A connection carrying the same current as its neighbours should run at the same temperature. When it does not, something is wrong.
We scan under normal operating load, because a panel inspected while the building is idle tells you very little.
What shows up on a scan
- Loose or corroded terminations running hot
- Unbalanced loads across phases
- Breakers operating beyond their comfortable range
- Deteriorating connections at lugs and busbars
- Overloaded circuits that have crept up over time
- Failing contactors and starters
Scan under load, not on a quiet Sunday
Thermal imaging only works when current is flowing. An inspection scheduled when the building is empty will show almost nothing. We plan the visit around when your equipment is actually running.
What a maintenance visit covers
The scope is set to your building rather than a generic checklist, but most programs include the following.
- Thermal survey of panels, disconnects, and distribution equipment
- Torque verification on accessible terminations
- Panel schedule review and correction of mislabelled circuits
- Load measurement and phase balance check
- Inspection of exposed conduit, cable, and supports
- Emergency and exit lighting testing with documentation
- GFCI and AFCI device testing
- Condition assessment of ageing equipment nearing replacement
How a maintenance program runs
- 1
Baseline survey
The first visit establishes what you have and its condition. That baseline is what later scans get compared against, which is how gradual deterioration becomes visible.
- 2
Agree scope and interval
Annual suits most properties. Buildings with heavy loads, critical operations, or ageing equipment often warrant semi-annual.
- 3
Scheduled visits
We work around your operations and coordinate with your facilities team or property manager.
- 4
Report and prioritised actions
You get a written report with thermal images, findings ranked by urgency, and clear separation between fix-now, plan-this-year, and monitor.
Reporting you can actually use
A maintenance report that just says everything looks fine is worth very little. Ours are written so a facilities manager can act on them and a finance director can budget from them.
Findings are ranked, photographed, and located. Where we recommend replacement rather than repair, we say why.
- Thermal images with the affected equipment identified
- Findings ranked urgent, planned, or monitor
- Location references so anyone can find the item later
- Comparison against the previous visit to show trends
- Documentation suitable for insurers and compliance files
Properties this suits
Preventative maintenance makes most sense where failure is expensive, where equipment is ageing, or where someone other than the occupier carries responsibility for the building.
- Warehouses and distribution facilities
- Multi-tenant commercial and mixed-use buildings
- Retail and restaurant sites where downtime stops revenue
- Managed residential portfolios with shared services
- Any building with equipment more than twenty years old

Frequently asked questions
- How often should commercial electrical maintenance happen? +
- Annual suits most properties. Buildings with heavy or continuous loads, critical operations, or equipment over twenty years old are often better served semi-annually. We recommend an interval after the baseline survey rather than before.
- What is thermal imaging actually looking for? +
- Heat where there should not be any. A connection carrying normal current should run at a normal temperature. When one runs hotter than its neighbours, it usually means a loose or corroded termination that will eventually fail.
- Do you have to shut the building down? +
- No, and it would defeat the purpose. Thermal scanning needs equipment running under normal load. Where a finding requires a shutdown to correct, we schedule that separately at a time that suits you.
- What do we get at the end? +
- A written report with thermal images, findings ranked by urgency, and location references. It is written to be usable by a facilities manager and suitable for insurance and compliance files.
- Will this satisfy our insurer? +
- Insurers increasingly ask for evidence of electrical maintenance, and our documentation is prepared with that in mind. Requirements vary by policy, so check the specific wording with your broker.
- Can you manage several properties? +
- Yes. For portfolios we report in a consistent format across sites, which makes it possible to compare buildings and prioritise capital spend where it matters most.
