PwC Celebrates Drone Technology Trial

pwc celebrates drone technology trial business manchester

In an innovative leap, a professional services firm has successfully completed its first stock count audit using drone technology. This breakthrough marks a significant milestone in operational efficiency.

The trial involved capturing over 300 images of a coal reserve, achieving in 30 minutes what traditionally required four hours. This not only showcases the potential time-saving benefits but also the technological prowess in modern auditing practices.

Efficient Audit with Drone Technology

The firm’s recent trial represents a pioneering effort in deploying drone technology for stock count audits. By utilising drones, the team was able to capture detailed aerial images of a coal reserve. This method proved to be significantly faster, reducing the audit time from four hours to just 30 minutes, illustrating a substantial improvement in efficiency.

Digital Twin Creation

The captured images were instrumental in creating a ‘digital twin’ of the 200-hectare coal pile. This digital replica allowed the team to accurately measure the volume of the coal reserve.

With 99 per cent accuracy, the value of the coal was calculated using the data from the digital twin. This high level of precision underscores the reliability of drone-assisted audits.

Safety and Accessibility

Drone technology also enhances safety during audits.

The preparation for the drone’s flight required access to only a small area of the coal pile, which significantly reduced health and safety risks. This is particularly important in areas where the coal pile may be unstable. Further, a multi-rotor drone was utilised to photograph the wider site. This enabled the site owner to inspect high or otherwise inaccessible assets effectively.

This dual functionality of drones improves both the safety and comprehensiveness of site inspections, making it a valuable tool in such environments.

Applications Across Sectors

The success of this trial opens the door for broader applications of drone technology across various sectors.

Industries with hard-to-reach assets, such as mining, agriculture, and forestry, stand to benefit considerably from drone technology. The ability to quickly and safely gather data in these sectors can lead to more informed decision-making and operational efficiencies.

Elaine Whyte, the firm’s drone technology leader, emphasised the potential for drones to deliver enhanced insights while saving time and money.

Skill and Technology Integration

To maximise the benefits of emerging technologies like drones, the integration of skilled professionals is crucial.

The firm is investing in attracting and training individuals capable of interpreting the data generated by drones. Hemione Hudson, head of assurance, highlighted the importance of having the right talent to ensure the highest audit quality.

This commitment to developing expertise in new technologies is essential for maintaining and improving audit standards.

Future Prospects

The success of this trial positions the firm at the forefront of technological advancements in auditing.

As industries continue to evolve, the integration of drone technology is poised to become more widespread. This trial serves as a benchmark for future audits and site inspections, leveraging the efficiency and precision offered by drones.

The firm’s adoption of this technology reflects a broader trend towards innovation and modernisation in professional services.

Conclusion

In summary, the trial’s success demonstrates the transformative potential of drone technology in auditing and beyond.

This initiative not only highlights significant time and safety improvements but also sets a precedent for the future integration of drones across various sectors.


The trial of drone technology by the firm marks a significant achievement in modern auditing. This innovative approach not only exemplifies efficiency and accuracy but also promises to redefine safety and operational standards in various industries.

As a forward-thinking initiative, this trial is likely to inspire further advancements and applications of drone technology, setting new benchmarks for the future.
