Drone Thermal Imaging Surveys.
Compare quotes from specialist UK drone operators for radiometric thermal imaging — detect heat loss, solar PV defects, and electrical faults invisible to the naked eye in a single flight.
“For every verified profile, we record the insurance and CAA credentials supplied at the time of review.”

Drone thermal imaging specialisms
Radiometric thermal payloads tuned to the specific fault you're trying to find.

PV hotspot and bypass-diode fault detection across utility and rooftop arrays.
Get solar thermal quotesM&E inspection
Electrical switchgear and mechanical plant thermography for preventative maintenance.
Request M&E thermalIndustrial process audit
Process equipment and refractory thermography for heat-loss and integrity assessment.

Solar drone operators, facilities managers, and building surveyors lose revenue and energy every month to defects that no visual inspection will ever find. Radiometric thermal imaging makes them impossible to miss.
Lost Solar Yield
A single bypass-diode failure on a modern string inverter can cut yield by 2–3% on that string. Across a 10MW farm, undetected anomalies easily wipe out five-figure annual revenue before anyone notices.
Heat Loss & EPC Exposure
MEES, EPC, and net-zero retrofit grants demand evidence of building envelope performance. A radiometric thermal survey overlays heat-loss data on every elevation — hard evidence for specifiers and funders.
Hidden Electrical Faults
Loose connections, overloaded busbars, and failing transformers all show as thermal hotspots long before they fail hard. A drone thermal sweep catches them without de-energising the asset or climbing the structure.
A colourful heatmap is not a thermal survey.

Connect on LinkedInMost hobby drone pilots with a thermal camera deliver pretty pictures and misread every other hotspot. A credible thermal survey needs the right sensor, the right time of day, the right emissivity settings, and a qualified interpreter.
Every thermal drone operator on this network flies radiometric sensors, holds ITC or BINDT Category 1+ thermography qualifications, and works under a CAA Operational Authorisation with £5M public liability.
Reports are interpreted, not just captured — so an O&M team, EPC contractor, or building surveyor can act on them immediately.
Category 1+ Thermographers
OA & £5M Public Liability
Reports O&M and facilities teams can action.
Our thermal specialists deliver radiometric deliverables ready for asset managers, EPC contractors, and insurance adjusters.
Radiometric R-JPEG
Per-pixel temperature data you can re-analyse in FLIR Tools, ResearchIR, or DJI Thermal Analysis — not a flattened heatmap. Change emissivity, reflected temperature, or palette post-flight.
Overlay-on-Visual Reports
Every thermal anomaly is paired with its high-resolution visual counterpart and GPS-tagged, so an O&M engineer or building surveyor can walk straight to the fault on site.
Solar Failure Reports
Every anomaly classified per IEC TS 62446-3 — hotspot, bypass diode, cell crack, PID, soiling — with module-level coordinates, severity rating, and yield-loss estimate.
Book your thermal survey in 3 steps.
We connect you with radiometric-rated drone operators who know when, where, and how to fly for defensible results.
Describe the Target
Tell us the asset (solar, building, substation), site size, and what decision the report needs to support. We advise whether the window is dawn, dusk, or mid-load.
Compare Specialists
We review the brief against relevant verified profiles and current availability. If listed supply is limited, we will say so and source availability manually. Any pilot introduced must confirm equipment, permissions, timing and deliverables for the actual job.
Fly & Interpret
Your drone pilot flies inside the correct thermal window, interprets the anomalies against the relevant standard, and delivers a packaged R-JPEG and overlay report.
