Thermal Imaging Surveys

Diagnostic thermography that enhances every survey we deliver.

Diagnostics

Thermography that actually answers the question

Thermography is a diagnostic discipline, not just thermal photography. We interpret thermal imagery in the context of how buildings, HVAC and electrical plant actually behave — producing reports you can act on, not just look at.

We deliver standalone thermal surveys, and routinely add thermography to TM44 and energy audit visits where it adds disproportionate diagnostic value for a small additional fee.

Who needs this?

Estate managers, FM teams and surveyors investigating heat loss, overheating, insulation defects, air leakage, moisture ingress, electrical hotspots, roof issues or PV array performance.

Where thermography pays off

Building fabric

Insulation defects, thermal bridging, air leakage and moisture ingress.

Plant & electrical

Hotspots in switchgear, distribution boards, motors and HVAC distribution.

Roofs & PV arrays

Trapped moisture under roofing and underperforming cells/strings on PV arrays.

How a thermal survey runs

Surveys are scheduled around the right environmental conditions so the imagery is genuinely diagnostic.

  1. 01

    Scope & objectives

    Define what you're trying to diagnose and the assets in scope.

  2. 02

    Conditions check

    Confirm temperature differentials, weather and load conditions for valid imagery.

  3. 03

    On-site survey

    Calibrated FLIR survey with paired thermal and visual imagery.

  4. 04

    Interpretation

    Findings interpreted in the context of building, plant and operational behaviour.

  5. 05

    Report & actions

    Prioritised report with severity, likely cause and recommended remediation.

How we help

Thermography that reads like a survey report, not a stock-photo gallery.

Common questions

Can thermography be added to other surveys?

Yes — combining thermography with TM44 inspections or energy audits gives much higher diagnostic value for a small additional fee.

What does a thermal report include?

Scope, environmental conditions, equipment used, paired thermal and visual images, findings, severity ratings, recommendations and stated limitations of the survey.

When is the best time of year for thermography?

It depends on the question — building fabric and heat-loss work favours colder months with a 10°C+ temperature differential; electrical and PV work runs year-round.

What equipment do you use?

Calibrated FLIR thermal cameras (research-grade and standard handheld) paired with visual imagery, plus drone-mounted thermal for large roofs and PV arrays where access is restricted.

Is thermography non-destructive?

Yes — entirely. No intrusion, no disruption to operations and no shutdown required. Most surveys are completed alongside normal building use.

Are your thermographers certified?

Yes — our thermographers hold ITC / PCN Category 1 or 2 certification with extensive building, M&E and PV experience.

Can you survey PV arrays for faults?

Yes — drone thermography identifies underperforming strings, hotspots, bypass diode failures and cell defects across rooftop and ground-mount arrays.

Will thermography pick up moisture in flat roofs?

Often yes — wet insulation retains heat differently from dry insulation, so a well-timed survey can map moisture ingress without core sampling.

How quickly can you produce a report?

Standard reports are issued within 5–10 working days of the survey. Critical electrical hotspot findings are flagged the same day verbally.

Can thermography support insurance or warranty claims?

Yes — independent thermographic evidence is regularly used to support insurance, warranty, latent defect and contractor performance claims.
