Registered, approved and independently certified
A loose connection gets hot long before it trips, sparks or starts a fire. We scan boards, switchgear and connections live, under normal load, with a calibrated infrared camera — so a developing fault shows up as a heat signature on a report, not as downtime or a callout.

Thermography sits alongside — not instead of — a periodic inspection. Every survey is carried out and reported against the specific standard your installation and insurer expect.
Sets out camera calibration, load conditions and reporting format for electrical thermographic surveys.
The international standard for infrared thermography as a condition-monitoring technique on electrical and mechanical plant.
Requires fixed electrical systems to be maintained to prevent danger — thermography is recognised evidence of that maintenance.
Loose connections and overheating components are a leading cause of electrical fire — findings feed directly into your fire risk assessment.
Many commercial and industrial policies require an annual thermal imaging survey of switchgear and distribution equipment to keep cover valid.
Where a survey identifies a fault, remedial work is carried out and certified against BS 7671 in the usual way.
We classify every anomaly by temperature rise above ambient/reference, so you know exactly how urgent each finding is before we leave site.
>40°C rise — immediate danger, isolated or made safe on site where possible
15-40°C rise — repair required within days, not the next scheduled visit
4-15°C rise — schedule repair, monitor at next survey if left
<4°C rise — noted for the record, re-check at the next scheduled survey
No thermal anomalies detected — passes for the survey interval
One or more T1 or T2 findings present — remedial action required
The right interval depends on load, duty cycle and consequence of failure — we scope to the sector and your risk profile, not a generic minimum.
Board thermal check bundled with the periodic inspection cycle
Main distribution boards and floor boards scanned yearly, often insurer-driven
Motor control centres and switchgear on a shorter cycle given fire load
Communal riser and plant room switchgear surveyed annually
Fixed sensor monitoring plus periodic full infrared survey
Critical and life-safety boards surveyed on a shortened interval
Kitchen extract and plant boards scanned given continuous high load
Kitchen and workshop boards surveyed ahead of each academic year
Refrigeration and plant switchgear on a shorter cycle given continuous duty
High-power charging infrastructure scanned under peak load conditions
A hot spot found early is a re-torque; found late, it's a burnt-out board. Pick the level of cover that matches how much of that gap you want us to close.
A recurring live thermal survey on a fixed interval, with every finding classified and reported.
Survey plus T1 and T2 remedial work carried out as part of the same visit.
Survey and remedial work with component or board replacement at end-of-life, built in and amortised.
Scoped to your total board and switchgear count across sites, with risk-based interval assignment.
A representative sample of recent work. Full case studies and references available on request.
Full infrared survey across three floor distribution boards, one T2 loose termination found and re-torqued same visit.
Survey across the main MCC and racking power distribution, one T1 emergency finding isolated and made safe on the day.
Refrigeration plant switchgear surveyed under peak compressor load, two T3 findings scheduled for next visit.
Life-safety and critical power boards surveyed on a 6-monthly cycle, no anomalies detected.
Fixed thermal sensors installed on critical UPS and distribution boards, backed by a full annual infrared survey.
Commercial kitchen extract and plant boards scanned under continuous load, one connector replaced after a T2 finding.
Riser and plant room switchgear surveyed annually across a managed block, no anomalies detected.
20-bay fleet charging hub scanned under peak simultaneous-charging load, no anomalies detected.

An infrared camera scans boards, switchgear and connections while the installation is live and under normal load, producing a heat map that reveals loose connections, overloading and failing components before they trip, spark or fail.
It depends on load and consequence of failure: annually is typical for commercial and industrial switchgear, 6-monthly for critical or continuous-duty plant such as healthcare, cold storage and data centres, and domestic boards are usually checked as part of the periodic inspection cycle.
No — thermography is a live, non-invasive check for heat-related faults under load. It complements a full periodic inspection (EICR) rather than replacing it, and is often used between EICR cycles to catch developing faults early.
Every finding is classified by severity (T1 to T4). T1 emergency findings are isolated or made safe immediately where possible; T2 findings are scheduled for repair within days; T3 and T4 findings are noted and monitored or scheduled for the next convenient visit.
