Typical thermal imaging inspection cost by job type
The ranges below are what US facilities commonly see for infrared electrical work. They are planning figures, not quotes, and regional rates and travel distance shift them.
| Job type | Typical range, not a quote | Usual unit |
|---|---|---|
| Small office or retail building, main panels only | $400 to $900 | Half day minimum |
| Warehouse or light industrial, 20 to 60 panels | $900 to $2,200 | Full day |
| Plant with switchgear, MCCs and transformers | $1,800 to $4,500 | One to two days |
| Multi building campus or hospital | $4,000 to $12,000 | Per survey, several days |
| Per panel pricing above a minimum | $25 to $75 | Per panel or enclosure |
| Hourly rate for a certified thermographer | $125 to $250 | Per hour |
| Electrician to open covers, if not your staff | $85 to $150 | Per hour |
A plant manager comparing three bids for the same building can see a spread of two to one. Most of that spread comes from what each bid includes, not from the hourly rate.
How thermographers price an electrical survey
Infrared contractors use four pricing models, and many quotes mix two of them.
- Half day or full day rate, the most common model for facilities with a known equipment list.
- Per panel or per enclosure price, common for small sites and for repeat annual surveys where the count is stable.
- Per project price for a defined scope, for example every switchboard, MCC and transformer on a site, with a fixed report.
- Hourly rate with a minimum, usually two to four hours, for small or unpredictable jobs.
Ask every bidder to quote the same equipment list, and convert the result to cost per enclosure scanned including travel and the report. That one number makes bids comparable.
What drives the price of an infrared electrical inspection
- Equipment count. Panels, disconnects, switchboards, MCC buckets, transformers and busway each take time to open, scan and photograph.
- Access and safety. Removing covers on energized gear needs a qualified electrical worker in arc flash PPE. If your own electricians open the panels, the bill drops.
- Infrared windows. Gear fitted with IR viewing ports can be scanned with covers on, which is faster and often cheaper over several years.
- Load. Faults only show under load, so many thermographers ask for at least 40 percent of normal load. Night or weekend scans to catch peak production add premiums.
- Thermographer level. A Level II or Level III thermographer certified under ASNT or ITC schemes costs more per hour than a Level I, but writes findings an insurer and an electrician can act on.
- Report format. A summary list is cheap. A full report with an infrared and a visual image per finding, temperature rise, severity class and repair priority takes longer to produce.
- Travel and mobilization. Sites far from the contractor's base pay for drive time, and remote sites may pay per diem.
Why facilities order infrared electrical inspections
Two outside pressures put this survey on most maintenance budgets. The first is NFPA 70B. Its 2023 edition turned the document from a recommended practice into a standard for electrical maintenance programs, and summaries from testing bodies describe it as calling for inspection of electrical equipment at least every 12 months, with infrared thermography the usual way to check connections under load. Check the edition your jurisdiction, insurer or corporate policy has adopted. The second is property insurance. Many carriers ask commercial and industrial clients for an annual infrared report, and a clean report is often part of the underwriting conversation. When you hire an outside thermographer, collect their certificate of insurance before they open your switchgear, and keep it current if you run the survey every year; a COI tracking system saves chasing expired certificates across contractors.
What a thermal imaging inspection report should include
- A list of every enclosure scanned, not only the ones with problems, so the survey proves coverage.
- For each finding, an infrared image and a visual photo of the same component.
- Measured temperature, reference temperature and the temperature rise, with the load at the time of the scan.
- A severity class and a recommended action, using a stated criterion such as NETA MTS temperature rise tables or the contractor's documented scale.
- The thermographer's name and certification level, the camera model and the emissivity settings used.
- A short repair list your electricians can work through, sorted by priority.
A report missing the full equipment list or the load data is the main reason a cheap survey ends up being repeated.
How the numbers add up on real jobs
A 120,000 square foot distribution center with 45 panels, two switchboards and a pad mounted transformer usually fits in one day. With the facility's own electrician opening covers, a typical bill is around $1,400 to $2,000 for the day and the report. If the contractor has to bring an electrician, add roughly $700 to $1,200.
A food plant with four MCC lineups, 12 switchboards and 80 panels, scanned at full production on a night shift, often runs two days. Expect $3,000 to $5,000 including the night premium, before travel.
A small office with three panels and a meter base is usually a half day minimum. Pairing it with a second building in the same trip is the easiest way to lower the cost per panel.
Costs that show up after the quote
- Return visits because gear was under light load on the first day.
- Panels skipped because they could not be opened safely, which leaves gaps the insurer asks about.
- Report revisions to add equipment IDs that were not on the original list.
- Repairs found by the survey, which are the point of the survey and should be budgeted. Re-scans after repairs are often discounted, so ask for that price up front.
How to lower thermal imaging inspection cost
- Send an accurate equipment list with locations, so the bid is fixed and the day is planned.
- Have your own qualified electricians open covers, and schedule the scan when production load is normal.
- Bundle several buildings or sites into one trip and one contract.
- Sign a multi year agreement for the annual survey, which most contractors price lower than a one off visit.
- Fit infrared windows on the gear you scan most often, which cuts PPE time and cover removal on every future survey.
What to put in your thermal imaging inspection request
- Site address, building type and operating hours.
- Equipment list by type and count: panels, switchboards, MCCs, transformers, busway, disconnects.
- Who opens the covers and whether infrared windows are installed.
- Expected load during the scan and whether a night or weekend window is needed.
- The criterion and report format you need, and whether the report goes to an insurer.
- Required thermographer level, insurance limits and site safety training.
- Deadline, for example a policy renewal date.
