Drone inspection services across the UK

Buildings and property

Roofs, chimneys, gutters and rainwater goods, façades, cladding and render, warehouses and commercial buildings. Aerial capture suits condition evidence on elevations and roof areas that would otherwise need access equipment. Where the scope is roof only condition imagery, see drone roof surveys. Where façades, cladding and wider external elevations are involved, see drone building inspection.

Energy

Ground mounted solar arrays, roof mounted PV, wind assets where the operation and permissions allow, and external electrical infrastructure where the scope is appropriately specified. See solar panel drone inspection, drone power line inspection and thermal drone surveys.

Infrastructure

Telecoms towers and masts, bridges, utilities assets, industrial structures and other hard to access external assets. These jobs often need specific permissions, method statements or client site approvals. For these asset types, see drone infrastructure inspection.

Specialist inspection assignments may require particular aircraft, sensors, experience, permissions or site procedures. These requirements are assessed before a pilot is matched to the job, so not every pilot will be suitable for every asset.

Drone Assisted assesses each enquiry individually. The location, required output, aircraft or sensor capability, pilot experience, relevant competency and operating requirements are considered before an assignment is confirmed.

It helps to separate two things: data capture and specialist interpretation.

Data capture

Drone pilots primarily capture imagery or other aerial data according to the agreed brief. Depending on that brief, deliverables may include:

• High resolution imagery of the agreed surfaces and elevations
• Video walkarounds and orbits
• Annotated imagery highlighting observed features
• Thermal imagery, where a suitably equipped pilot is available, showing temperature differences for further investigation
• Evidence packs for insurers, asset managers and surveyors, structured as agreed in advance
• Repeat capture where requirements are agreed in advance to support more consistent comparison between visits
• Original unedited files where requested

Where a particular report format or evidence structure is required, this should be specified before the assignment. Capture and delivery times are agreed according to the requirements of the assignment.

Thermal imagery

Thermal imagery can identify temperature differences or anomalies that may warrant further investigation, for example in relation to suspected heat loss, moisture or electrical hot spots. The usefulness of thermal data depends on factors including sensor capability, environmental conditions, surface materials, time of day and the methodology used. Where thermal capability is required, Drone Assisted will seek to identify a suitably equipped pilot for the assignment.

Specialist interpretation

Where engineering, surveying, roofing, electrical, thermal, loss adjusting or other specialist interpretation is required, this may need to be completed by an appropriately qualified professional. Capture gives that person better evidence to work from; it does not replace their professional judgement or sign off.

• Condition monitoring of assets you need to keep an eye on without booking access each time.
• Planned maintenance scoping, so works are priced against evidence rather than assumption.
• Insurance evidence captured with date, location and consistent coverage.
• Storm damage assessment shortly after an event, before access equipment can be mobilised.
• Construction progress records and quality checks on completed elevations.
• Repeat condition monitoring where capture requirements are agreed in advance to support more consistent comparison between visits.
• Portfolio inspection across multiple sites on a consistent specification.
• Difficult visual access such as steep pitches, atria, chimneys and tall structures.
• Pre work assessment to scope access, materials and programme before committing to scaffolding.

Drone inspection is often an efficient first stage visual data collection method, but some findings may require follow up physical or specialist inspection. A drone does not replace:

• Physical testing such as adhesion, pull off or moisture meter readings
• Touch inspection where hand on substrate assessment is specified
• Intrusive investigation and opening up works
• Material sampling and laboratory analysis
• Repair or remedial works of any kind
• Internal access, or areas where flight is unsuitable or not permitted
• Engineering sign off and certification
• Specialist surveying opinion

Each method has a job it does best. The right choice depends on the asset, the brief and whether physical contact is needed.

• Mobilisation. Drone and MEWP are usually quickest to arrange. Scaffolding needs design, permits and erection time. Rope access needs a qualified team and a rescue plan.
• Visual access. Drone reaches most external surfaces including steep and tall areas. MEWP is limited by reach and ground conditions. Scaffolding and rope access give close visual access to the areas they cover.
• Physical access. Only scaffolding, MEWP and rope access put a person on the structure. A drone cannot touch the asset.
• Site disruption. Drone flights are short and usually need little ground space. Scaffolding and MEWP can affect access, parking and highways.
• Data capture. Drone capture can cover external surfaces methodically, subject to the agreed scope and safe operating conditions. Manual capture depends on where the inspector can stand.
• Repeat visits. Repeat aerial imagery can help organisations monitor visible changes in the condition of buildings, infrastructure and other assets over time, where capture requirements are agreed in advance.
• Physical testing. Not possible by drone. Where testing, sampling or repair is in scope, physical access is required regardless.

Cost and safety outcomes vary by site, so we assess each brief on its merits rather than assuming a drone is always the cheaper or safer option. Ready to proceed? Hire a UK drone pilot and we will confirm availability.

This page is the hub for commercial drone inspection and aerial inspection services. Where a job needs a specific type of capture, these pages go into more detail:

• Drone roof inspection for pitched, flat and commercial roof condition imagery.
• Drone building inspection for aerial inspection of façades, cladding, roofs and other external building structures.
• Thermal drone surveys where temperature anomalies need identifying for further investigation.
• Solar panel drone inspection for module level fault indication across PV arrays.
• Drone infrastructure inspection for bridges, towers, utilities, industrial and transport assets.
• Drone surveying where measurement data rather than condition evidence is required.

Drone Assisted checks pilot identity, commercial drone insurance and appropriate CAA registration as part of network onboarding. Additional competency, qualifications, specialist equipment and Operational Authorisation are checked where required for the proposed assignment.

The exact requirements depend on factors including the aircraft, location, surrounding environment, airspace and nature of the operation. See commercial drone pilot requirements for more detail.

Where non destructive testing evidence is required, inspection outputs can be supplied in formats suited to BINDT qualified engineers and building surveyors registered with RICS, where agreed in advance. The network follows the professional standards promoted by ARPAS UK.
