Drone Utility & Powerline Surveys.
Compare quotes from specialist UK drone operators for powerline, pylon, substation, and water/gas infrastructure inspection — with thermal fault detection, corridor ortho, and pylon-by-pylon condition data, without climbing crews.
“For every verified profile, we record the insurance and CAA credentials supplied at the time of review.”

DNOs, IDNOs, and utility asset teams still send climbing crews up to eyeball fittings when a thermal drone would catch every fault in a fraction of the time. Drones change the economics completely.
Outage & Climbing Costs
Isolating a 132kV circuit to allow a climbing inspection costs tens of thousands in CI/CML penalties and crew time. A drone inspection keeps the line live and captures closer-range imagery than a climber ever could.
Hidden Thermal Faults
Loose jumpers, failing clamps, and cracked insulators show as temperature anomalies long before they fail. Radiometric thermal imagery catches those faults on a live conductor and feeds them straight into your ENMAC or CBM workflow.
Working-At-Height Exposure
Climbers, MEWPs, and helicopters all put staff close to live conductors. A drone removes the climbing exposure entirely while still capturing close-range imagery of every cap and pin.
Live-line flying isn't for hobbyists.

Connect on LinkedInFlying within arc-flash distance of a 400kV circuit is not a job for a standard A2 CofC drone pilot. The approach distances, magnetic interference on the compass, and induced voltage all demand specialist training and a bespoke CAA Operational Authorisation.
Every utility survey on this network is flown by drone operators with ITC Level 1/2 thermography, DNO-approved method statements, and bespoke OAs for proximity to live conductors. They carry £5M+ public liability as standard.
The result is survey data that feeds directly into ENMAC, IPS, or your in-house CBM register without rework.
Thermal & DNO Qualified
ITC & £5M Public Liability
Outputs your asset team can plug in.
Our network operators deliver survey-grade outputs ready for DNO asset registers, Ofgem RIIO submissions, and in-house CBM workflows.
Pylon-By-Pylon Condition
A structured condition record per tower: legs, earthwire attachments, insulators, jumpers, and dampers. Each asset gets a scored defect register with supporting close-range imagery.
Thermal Fault Detection
Radiometric thermal imagery captured with calibrated cameras at live-line loading. Hotspots are tagged, delta-T measured, and exported into your CBM system for prioritised intervention.
Corridor Ortho & Clearance
Georef'd corridor ortho with conductor-to-ground and vegetation clearance measurements, ready to drop into your GIS for compliance against ENA ETR 132 and Health & Safety Executive guidance.
Book your utility survey in 3 steps.
Submit one brief. We aim to review it within one working day, then introduce relevant independent specialists who can assess the project.
Describe the Asset
Tell us the voltage level, asset count, substation size, or pipeline corridor length, and what you need documented. Takes under two minutes.
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.
Inspect & Report
Your drone pilot coordinates with the DNO, flies the line or substation live, and delivers a packaged report with pylon-by-pylon condition, thermal faults, and corridor ortho.
Utility Survey FAQ
Technical questions on live-line flying, thermal standards, and deliverables.
Can the drone fly safely near a live 400kV circuit?
What thermal camera and standards are used?
What weather prevents a utility survey?
Do I get raw imagery as well as the report?
Ready to ditch the climbing crews?
