Landmark Health and Safety Executive (HSE) permit, delivered in partnership with Certis Belchim, paves the way for AutoSpray Systems to use a revolutionary new method to clean glasshouses and boost crop performance.

Stoke-On-Trent, UK – June 11, 2025– AutoSpray Systems, leaders in the UK’s agri-drone revolution and an ARPAS-UK Member, today confirmed they have been awarded the first-ever UK trial permit by the Health and Safety Executive (HSE) for the aerial application of a biocide.

This significant regulatory milestone, achieved in partnership with crop protection specialists Certis Belchim, covers the aerial drone application of an algaecide to tackle widespread algae build-up on glasshouse roofs. This represents the first step towards securing a full commercial authorisation for the practice.

Algal films on glass are a growing issue for the UK horticultural sector, caused by increasingly damp and mild weather conditions. The build-up significantly reduces light transmission, limiting crop performance and reducing energy efficiency in high-value protected cropping systems. Traditionally, cleaning these structures is labour-intensive, disruptive, and often impractical at scale.

Andy Sproson, Director at AutoSpray Systems, commented, ‘Securing this landmark permit from the HSE is a testament to our team’s hard work and our close, collaborative relationship with UK regulators. This isn’t just about cleaning glass; it’s about providing the horticulture sector with a powerful new tool to enhance productivity and operate more safely. We are proving that drone technology offers smarter, cleaner, and more efficient solutions to long-standing industry challenges, and we’re excited to be leading the charge towards full commercial approval.’

The aerial drone solution allows glasshouses to be treated quickly and safely without the need for scaffolding or access platforms. The application is precise, consistent, and repeatable, ensuring light levels can be rapidly restored to improve crop growth and uniformity.

This permit marks the beginning of a full regulatory pathway toward commercial approval. It is a transformative development for the UK horticultural sector, showcasing how drone technology can solve practical challenges with safer and smarter application methods.
