Sheerline has announced the continuation of its outstanding delivery consistency, reporting an On Time In Full (OTIF) rate of 99.4% across the entire 2025 calendar year. While the company is no stranger to industry recognition, this achievement reflects not an award but sustained operational excellence, built on rigorous planning, investment, and internal discipline.
To emphasise that this milestone is the result of methodical improvement rather than short-term success, Sheerline has been regularly communicating OTIF performance through customer updates, marketing campaigns, and social media. This transparency has not only reinforced brand trust, but also supported customer planning, enabling manufacturers and fabricators to schedule production accurately, manage workforce allocation, and confidently meet deadlines.
According to the company, consistent delivery performance has become a direct value advantage for its network. Customers know precisely when products will arrive and in what quantities, reducing uncertainty and strengthening reliability in their own downstream commitments.
Ross Hartshorn, Technical Production Director at Sheerline, highlighted the team’s achievement: 
Over the past 12 months we’ve not only increased our OTIF, but we’ve maintained it – even achieving an OTIF of 100% for a period. Anyone who works in manufacturing knows what an achievement this is.
Hartshorn further explained that the results are rooted in strategic improvements at every stage of production. These include investments in upgraded machinery, process refinement, and enhanced internal training programmes, all designed to ensure better synchronisation across production, fulfilment, and logistics.
“It’s the result of changes we’ve made to our machinery, our processes, and internal training to ensure our production teams are working as harmoniously as they possibly can be. It’s clear this approach is working, but we’re always looking for ways to improve,” he said.
With manufacturing pressures and supply chain challenges continuing to test operational resilience across the UK, Sheerline’s consistent OTIF performance sets a benchmark for service reliability in the fenestration sector. The company affirms that continual refinement will remain a priority as it looks ahead to 2026.
