What Grange does

Grange Quarry Ltd is a family-run, private limited UK supplier of aggregates, ready-mix concrete, and ancillary construction and agricultural materials, founded in 2000 by Stuart and Lynn Dodd with a single whinstone quarry at Tundergarth (Lockerbie). The company has expanded to five static production sites — Tundergarth (whinstone), Kirkburn/Lockerbie (concrete), Kinmount/Annan (Kelhead limestone), Dalbeattie, and Earlston — together with four mobile batching plants (60–120m³/hour) capable of full UK deployment. Its core output is high-PSV whinstone and limestone aggregates supplied alongside BSI Kitemark accredited ready-mix concrete conforming to BS EN 206-1 and BS 8500-2; ancillary lines include Cemfloor liquid screed, calcium agricultural lime (50,000 t/yr capacity at Kelhead), ENA-certified cable sand, rock armour, gabion stone, and aggregate recycling (MOBIREX MR 122 Z impact crusher and CDE M2500 E4 wash plant).

The business sells primarily through enterprise B2B field sales to civil engineering contractors and infrastructure developers, with direct delivery and customer collection from static plants serving regional customers (Dumfries and Galloway, Scottish Borders, Cumbria) and mobile plant hire serving national renewables and infrastructure projects. Pricing is quote-based; payment terms are due before delivery or within 30 days of month-end invoice. Third-party commercial testing services (compressive strength, density, slump, Methylene Blue clay analysis) augment the core supply offering and provide a recurring revenue stream outside peak construction cycles.

Certifications underpinning the offering include ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, BSI Kitemark KM 562490, and BSI CPR 771576-001 for high PSV asphalt aggregate; management remains family-controlled with Stuart Dodd as Managing Director and Lynn Dodd as Company Secretary/Director across a headcount of approximately 19 employees spanning operations, transport, technical, accounts, sales, and dispatch functions.
