The British Aggregates Association (BAA) is dedicated to upholding rigorous standards within the aggregates industry, ensuring that operational activities in depots and quarries meet essential benchmarks while being managed with competency. Through our Assessed Operating Standards (AOS) scheme, we provide third-party accreditation to our members’ operations, validating their adherence to these standards.

Recognised by the Health & Safety Executive (HSE), the AOS scheme offers assurance to stakeholders and customers alike that our members prioritise safety, efficiency, and professionalism in their operations.

Recent Achievements

Over the past 18 months, Tillicoultry Quarries has been actively engaged with the BAA, undergoing reassessments for units participating in the AOS scheme. We are delighted to announce that both Hullerhill Depot and Tams Loup Quarry successfully passed their reassessments in 2023, a testament to the dedication and competence of all involved at these locations.

Furthermore, at the BAA annual conference in late 2023, Hullerhill Depot was honoured with a Highly Commended Certificate, while Tams Loup Quarry was celebrated as the Quarry of the Year. Both locations achieved a remarkable 100% pass rate on their assessments, reflecting their unwavering commitment to excellence.

In early 2024, Northfield Quarry joined the ranks of success by passing their reassessment with flying colours, achieving a perfect 100% pass mark. Congratulations are in order for John McNab, Matt Clark, and the entire team at Northfield Quarry for their outstanding accomplishment.

We applaud and celebrate the continuous efforts to maintain and exceed operating standards, setting a benchmark for excellence in the aggregates industry.
