Choosing a thermal imaging consultancy is not a like-for-like decision. The UK thermography market is unregulated, which means certification levels, reporting quality, and turnaround times vary widely between providers, even when the quoted price looks similar.
This checklist sets out the six areas that matter most when you are comparing consultancies for electrical, mechanical, or building thermography: certification, report standards, independence, reporting speed, insurer acceptance, and scope of services.
Key Takeaways: Evaluating a Thermal Imaging Consultancy
- Verify your consultancy holds at least ITC Level 2 certification, ideally Level 3 for complex sites.
- Insist on sample reports showing ΔT measurements, load-corrected temperatures, and standardised fault grading.
- Check whether reports are generated on site or delayed by days of office-based post-processing.
- Confirm the consultancy is independent of equipment manufacturers and camera sales.
- Ask whether reports have a track record of being accepted by insurers and compliance auditors without follow-up queries.
1. Certification Level
Certification is the fastest way to separate a qualified thermographer from someone who has simply bought a camera. At minimum, look for ITC Level 2 or equivalent certification under ISO 18436-7. Level 3 thermographers can design inspection programmes and interpret complex, multi-discipline findings — this matters for industrial sites, data centres, or anywhere the consequences of a missed fault are high.
Ask for certificate numbers and verify them directly. A consultancy that cannot produce evidence of accredited training is introducing risk into every report it signs off.
2. Report Standards and Load Correction
A report with no load correction data is incomplete. Electrical components generate different heat signatures depending on operating load, so a reading taken at 40% load can understate a fault that would be Critical at full capacity. Ask to see a sample report and look specifically for ΔT measurements, load-corrected temperature values, and a clear reference to BS7671 or the equivalent standard.
Ti Thermal Imaging applies Automatic BS7671-Compliant Load Correction to every electrical report, removing manual calculation error from the process.
3. Independence
Ask whether the consultancy also sells or rents thermal imaging equipment. That is not disqualifying on its own, but an independent consultancy — one whose only commercial interest is the accuracy of the inspection — gives your insurer and your own team more confidence that findings are not shaped by a parallel equipment business.
4. Reporting Speed
Ask directly: will the report be generated on site, or will it arrive days or weeks later after manual processing? A delay of several days leaves faults undocumented and unaddressed in the meantime. On-site, same-day reporting — as Ti Thermal Imaging delivers through its TICOR™ platform — means critical findings reach your maintenance team before the thermographer has left the building.
5. Insurer and Compliance Acceptance
Insurance compliance is an increasing driver of thermographic surveys across UK commercial and industrial property. Ask whether the consultancy’s reports have a track record of being accepted by insurers and auditors without additional queries. Reports aligned to ISO 18436-7 and BS7671, with standardised fault grading and clear remedial actions, are far more likely to be accepted first time than a folder of unannotated thermal images.
6. Scope of Services
Consider whether one consultancy can cover electrical, mechanical, HVAC, and building envelope inspections, or whether you will need to coordinate multiple providers. A consultancy with documented experience across your specific sector — data centres, manufacturing, commercial portfolios — is more likely to tailor its inspection protocol to your actual risk profile rather than applying a generic checklist.
Putting the Checklist to Work
A consultancy that can answer all six of these points with specific, verifiable evidence is operating at the standard your facility needs. Ti Thermal Imaging holds ITC Level 3 certification, reports to ISO 18436-7 and BS7671, and delivers same-day, on-site reporting through TICOR™ and WEBCOR™.

FAQs: Choosing a Thermal Imaging Consultancy
What is the minimum certification I should accept?
ITC Level 2 or equivalent under ISO 18436-7 as an absolute minimum. Level 3 is preferable for industrial, data centre, or multi-discipline sites.
Why does load correction matter?
Without correcting for the load present during inspection, a fault can appear less severe than it would be at full operating capacity, which risks under-reporting genuine risk.
How quickly should I expect a report?
Same-day, on-site reporting is achievable with the right technology. Delays of several days typically indicate manual, office-based processing.
Do insurers really check the standards behind a report?
Many UK insurers expect reports aligned to ISO 18436-7 and BS7671, with fault grading and remedial recommendations, as evidence of proactive electrical risk management.
