Our engineers can complete a survey in a day or over the course of a few days or weeks, depending on your circumstances. We always recommend monitoring your indoor environment quality (IEQ) — including temperature — for at least 72 hours to gather enough data to take demonstrable actions.

We prefer temperature mapping to be conducted during normal operating hours, as this gives us data which accurately represents real working conditions — allowing us to fix issues quicker and more effectively.

We always prefer to conduct temperature assessments over a number of days or weeks to ensure we are provided with realistic data and understand the whole picture.

The IAQ monitors we use, which also record temperature, are professional-grade, regularly calibrated, and widely trusted by the industry — as are our thermal imaging devices. With both of these technologies combined, we can assess temperatures over long periods to measure averages and identify spikes, and we can also record in-the-moment temperatures with our handheld devices to identify spots causing trouble.

To identify HVAC problems, thermal cameras and sensors effectively make air distribution visible by capturing temperature differentials created by supply and return air. They pinpoint blocked diffusers, poorly balanced zones, leaking ductwork, and areas receiving insufficient conditioned air — all key factors in a temperature mapping qualification.

A temperature mapping service is a systematic process of measuring, recording, and analysing temperature (and sometimes humidity) distribution across a controlled space over time. 

This service identifies hot or cold spots, validates that an environment consistently meets regulatory thresholds, and produces documented evidence for compliance audits. With us, you receive a personalised post-assessment report detailing our findings, suggestions, and proof that you've taken action to secure the correct temperatures in your space.

Pharmaceutical manufacturers, biotech labs, hospitals, blood banks, food processing facilities, cold chain logistics providers, and any regulated industry where product integrity depends on maintaining specific environmental conditions.

We recommend mapping after initial installations, after any structural renovations or layout changes, major equipment changes, and at least annually for ongoing proof of compliance.

Temperature mapping exercises should be repeated throughout the year to cover seasonal variations, according to the MHRA Inspectorate (2016)

High-risk environments may require temperature mapping more frequently.
