We are thrilled to announce that Principle Cleaning Services’ vertical services has been awarded third place in the Tomorrow’s Cleaning Awards 2026.
Innovation sits at the core of Principle’s vertical cleaning services, driving performance, transparency and safety. From drone window cleaning to real-time, cloud-based platforms, technology is transforming how Principle delivers exceptional results for clients.
In 2024, Principle introduced drone window cleaning – a breakthrough that turned the impossible into reality. For the first time since construction, previously inaccessible areas of buildings across London are now within reach. The technology reduces cleaning time by up to 75%, delivers zero-emission operation and significantly enhances safety, efficiency and sustainability. Client response has been outstanding, leading to the launch of Principle’s dedicated drone cleaning division.
Principle has also pioneered several in-house innovations. PCS Hub, our secure, cloud-based, dashboard-style platform, provides clients with a real-time, dashboard-style view of their portfolio, empowering quick, informed decision-making with full visibility across operations. Embedded within the platform is proprietary 3D Mapping technology, which monitors performance across multiple sites down to individual windows. Clients can see exactly when and how windows are cleaned, track standards and instantly log defects.
Principle’s Drop Marking system, used daily by our vertical team to record the duration of each cleaning drop, feeds directly into the 3D Mapping platform. This creates a closed-loop, data-led approach to monitoring progress, managing performance and optimising resources. In real-time, our clients can access live reports on project status, compliance, financials and resource utilisation. The result – smarter decisions, measurable value and unprecedented transparency of cleaning schedules, ensuring clients receive the services they pay for.
David Saville, Managing Director – Vertical & Specialist Cleaning, said:
“We’re incredibly proud of our vertical team for this recognition. Their dedication, expertise, and commitment to innovation are what set Principle apart in the window cleaning sector.
From drones to real-time data platforms, we continue to push the boundaries of what’s possible, delivering safer, smarter and more sustainable solutions for our clients. This award is a testament to the talent, creativity and forward-thinking approach of everyone involved.”
A huge congratulations to all winners and finalists, and a special well done to our vertical team – we’re thrilled to see their incredible work recognised. Innovation is at the heart of everything we do and we remain committed to continuously excelling and pushing the boundaries of service.
