7 Questions Before Hiring a Thermal Imaging Consultancy

Hiring the wrong thermal imaging consultancy costs more than the survey fee. It costs you missed faults, rejected insurance documentation, and remedial work that never gets prioritised.

The UK thermography market is unregulated. Anyone with a camera can call themselves a consultant. That means the burden falls on you to verify credentials, reporting quality, and standards alignment before signing a contract. Ti Thermal Imaging helps facilities and industrial teams close that gap with ITC Level 3 certified inspections, ISO 18436-7 aligned reporting, and audit-ready documentation delivered on site.

This article gives you seven questions to ask before appointing your next thermal imaging consultancy. Each one targets a specific risk that generic consultancies routinely leave unaddressed.

Key Takeaways: Questions Before Hiring a Thermal Imaging Consultancy

  • Verify your consultancy holds at least ITC Level 2 certification and can demonstrate compliance with ISO 18436-7.
  • Ask for sample reports showing ΔT measurements, load correction data, and standardised fault grading.
  • Confirm whether reports are generated on site or delayed by days of post-processing back at the office.
  • Ti Thermal Imaging delivers same-day, client-ready PDF reports using its TICOR™ reporting platform.
  • Check that the consultancy grades faults as Minor, Important, Serious, or Critical with clear remedial actions.

7 Essential Questions for Evaluating a Thermal Imaging Consultancy

1. What Thermography Certifications Do Your Engineers Hold?

Certification level is the single fastest way to filter out unqualified consultancies. At a minimum, your consultancy should employ thermographers certified to ITC Level 2 or equivalent under ISO 18436-7. This standard defines the competence requirements for personnel conducting thermographic inspections of machines and electrical systems.

Ask for certificate numbers and verify them. A consultancy that cannot produce evidence of accredited training introduces risk into every report it generates.

2. Do Your Reports Include Load Correction and ΔT Data?

A thermographic report with no load correction data is incomplete. Electrical components generate different heat signatures depending on their operating load. Without applying BS7671-compliant load correction formulae, the reported temperature may understate or overstate the true severity of a fault.

Ask your prospective consultancy to show you a sample report. Look for ΔT measurements, load-corrected temperature values, and a clear reference to the standard cable temperature. Ti Thermal Imaging applies Automatic BS7671-Compliant Load Correction in every electrical thermography report, removing the risk of human error in these calculations.

3. How Do You Grade Fault Severity?

Inconsistent fault grading creates confusion across your maintenance team. If one report labels a fault as “high priority” and the next calls the same condition “moderate,” your engineers cannot prioritise remedial work effectively. The industry-recognised severity scale uses four categories: Minor, Important, Serious, and Critical.

Your consultancy should apply these grades consistently across every inspection. Standardised Fault Grading removes ambiguity and gives your insurers, auditors, and maintenance planners a common language for tracking faults over time.

4. When Will I Receive the Report After Inspection?

Report turnaround is where many consultancies fall short. If your thermographer returns to the office, downloads images to a laptop, and manually assembles a document, you could wait days or even weeks for the final deliverable. That delay leaves critical faults undocumented and unaddressed.

On-Site Instant Reporting changes that timeline entirely. Ti Thermal Imaging generates client-ready PDF reports before the engineer leaves your facility, using its proprietary TICOR™ platform on a field tablet. No laptop. No post-processing. No rework.

5. Are Your Reports Accepted by Insurers and Auditors?

Insurance compliance is a growing driver for thermographic surveys across UK commercial and industrial properties. Your insurer may require evidence that electrical infrastructure has been inspected under load by a certified thermographer, with documented findings that meet recognised standards.

Ask your consultancy whether their reports have been accepted by major insurers and building compliance bodies. Reports aligned to ISO 18436-7 and BS7671, with Automatic Problem Grading and clear remedial actions, are far more likely to satisfy these requirements than generic image-only summaries.

6. Can You Demonstrate Sector Experience in My Industry?

A consultancy that inspects offices may not understand the electrical loading patterns inside a data centre or the HVAC distribution in a pharmaceutical facility. The consultancy you hire should be able to reference relevant sector experience and explain how their inspection scope adapts to your specific environment.

Ti Thermal Imaging has delivered industrial thermographic inspections for data centres, manufacturing plants, oil and gas sites, and commercial building portfolios. That operational breadth means the inspection protocol matches the risk profile of your facility, not a generic checklist.

7. Do You Support Trending and Condition Monitoring Over Time?

A single thermal survey is a snapshot. Without trending data, you cannot track how a fault progresses between inspections or confirm that a remedial action resolved the issue. Your consultancy should be able to compare current and historical thermographic findings at the component level.

Ti Thermal Imaging enables trending analysis through SnapCor and WEBCOR™, tracking temperature and load data for each asset across repeated inspections. This turns a one-off survey into a repeatable maintenance programme that supports condition monitoring and predictive planning.

How to Choose the Right Thermal Imaging Consultancy for Your Facility

The seven questions above cover the areas where facilities managers and maintenance teams face the most risk when appointing a thermal imaging consultancy: credentials, report quality, turnaround time, insurer acceptance, sector knowledge, and long-term trending capability.

A consultancy that cannot answer these questions with specific, verifiable evidence is not operating at the standard your facility requires. Ti Thermal Imaging gives you ITC Level 3 certified engineers, ISO 18436-7 and BS7671 aligned reporting, and same-day delivery through TICOR™ and SnapCor.

FAQs About Hiring a Thermal Imaging Consultancy

What qualifications should a thermal imaging consultant hold?

At minimum, your consultant should hold ITC Level 2 certification and work to ISO 18436-7. Ti Thermal Imaging employs ITC Level 3 certified thermographers who deliver audit-ready reports aligned to BS7671 and ISO 18436-7.

How long should a thermographic survey report take to deliver?

A report should be delivered the same day as the inspection. Delays of days or weeks indicate manual, office-based workflows. Ti Thermal Imaging generates complete PDF reports on site using its TICOR™ field reporting platform.

What standards apply to electrical thermography in the UK?

BS7671 (IET Wiring Regulations) and ISO 18436-7 are the primary standards for electrical thermography reporting. NFPA 70B also mandates thermographic inspection of electrical connections at defined intervals.

Do insurers accept thermographic inspection reports?

Many UK insurers accept thermographic reports as evidence of electrical maintenance compliance. Reports must include fault grading, load correction data, and clear remedial recommendations to meet insurer requirements.

Can thermal imaging detect faults without shutting down equipment?

Yes. Infrared thermography is a non-contact, non-invasive method that detects overheating in live electrical and mechanical systems. Equipment stays fully operational during the survey. Ti Thermal Imaging performs no-shutdown inspections across all its electrical and building surveys.

What is fault grading in thermographic reporting?

Fault grading classifies each detected anomaly by severity: Minor, Important, Serious, or Critical. This classification drives maintenance priority, remedial planning, and insurer documentation. Ti Thermal Imaging applies consistent, standardised severity grading across every inspection.
