Thermal drones

Overview

Thermal drones use infrared cameras to detect heat signatures — used for building energy audits, power line inspections, fire reconnaissance and search-and-rescue operations.

Having a thermal camera on a drone does not automatically make the operation Specific category. Licence requirements are determined by flight location, proximity to people and aircraft MTOM — not the type of sensor installed.

Rules

For thermal inspections in commercial settings, an A2 certificate with a C2-class aircraft is generally sufficient. If the inspection involves flying over urban areas or people, STS-01 authorisation is required.

Thermal drone use is legally regulated by GDPR. Thermal images that identify individuals or reveal the interior of private premises may fall within personal data protection scope. A commercial operator should conduct a data protection impact assessment.

Licence

For commercial thermal inspections you need: operator registration, an A2 or STS certificate, commercial OC insurance and, where applicable, GDPR compliance documentation.

Thermal operations often take place at night (energy audits, moisture mapping) — night flights require a separate NAA permit or Specific category authorisation. For full registration requirements see /blog/drone-operator-registration-eu.

Next step

For those starting in thermal operations: first obtain an A2 certificate, then assess whether planned operations stay within Open-category limits or require a Specific permit.

Thermal drone inspections face growing demand in construction, energy and search-and-rescue sectors. A licence and insurance are an investment in professional credibility.

Frequently asked questions

Does a thermal camera on a sub-250g drone affect licence requirements?

A thermal camera is a camera and may affect the sub-250g C0 registration exemption. Check TKA guidance for the specific national interpretation of thermal cameras on small drones.

Does GDPR apply to thermal imagery?

If thermal images identify individuals or reveal private interior spaces, GDPR may apply. For commercial operations, consult a data protection specialist.
