How Long Does a Thermal Imaging Survey Take? An In-Depth Look

A common question we encounter in the field of electrical maintenance is, “How long does a thermal imaging survey take?”

This query is crucial for businesses and property owners who need to plan for minimal disruption during maintenance.

In this post, we’ll delve into the factors that determine the duration of a thermal imaging survey, providing insights into what to expect and how to prepare.

Understanding the Duration of a Thermal Imaging Survey

  1. Site Access and Preparation Time

One of the primary factors affecting how long a thermal imaging survey takes is the time required to access the site.

In facilities such as industrial plants or government buildings, security protocols can extend access times significantly.

For instance, staff inductions and security clearances can take anywhere from a few minutes to several hours, especially in sensitive areas like Ministry of Defence sites.

  1. Access Equipment and Setup Time

The necessity of access equipment and its setup time also influences how long a thermal imaging survey takes.

In cases where equipment like ladders, scaffolding, or cherry pickers are required to reach high or confined spaces, additional time is needed for setup and dismantling.

Ensuring that this equipment is safely and correctly installed is paramount and cannot be rushed, as it directly impacts the safety of the surveyors.

  1. Time to Remove Live Panel Covers or Fit Thermal Imaging Windows

Another aspect to consider in determining how long a thermal imaging survey takes is the time it takes to prepare the electrical systems for inspection.

This includes removing live panel covers or fitting thermal imaging windows.

These tasks must be done with utmost care and precision to maintain safety, adding more time to the survey.

  1. Conducting the Survey Itself

The survey itself varies in duration depending on the size and complexity of the building or facility.

A small residential property might take only a few hours, whereas a large commercial building or an industrial plant with complex electrical systems could take days or weeks.

The time taken for the actual survey is a critical component of how long a thermal imaging survey takes.

  1. Complexity of Electrical Systems

The complexity of the electrical systems being surveyed directly impacts how long a thermal imaging survey takes.

More complex systems with numerous components, such as distribution boards, transformers, and machinery controls, require a more thorough and time-consuming inspection to ensure no potential issues are overlooked.

  1. Documentation and Reporting

Post-survey documentation and reporting also contribute to how long a thermal imaging survey takes.

Compiling the data, analysing the thermal images, and preparing a comprehensive report that outlines the findings and recommendations can be a time-intensive process, especially for more extensive surveys.

  1. Unforeseen Delays

Finally, unforeseen delays can affect how long a thermal imaging survey takes.

These can include equipment malfunctions, additional safety measures needed due to unexpected site conditions, or extended time required to access certain areas within the facility.

How does thermal imaging work?


In conclusion, how long a thermal imaging survey takes depends on various factors, from site access and preparation to the complexity of the electrical systems and post-survey reporting.

Businesses and property owners need to understand these factors to effectively plan for a thermal imaging survey.

While it may seem time-consuming, the benefits of accurately identifying and addressing potential electrical issues far outweigh the inconvenience of the time taken.

For those considering a thermal imaging survey, remember to factor in these various elements to get a realistic estimate of how long the process will take.
