What Gallaher Group does

Gallagher Group is a privately held, family-owned construction materials and services company headquartered in Aylesford, Kent, founded in 1973 by Pat Gallagher. Operating across three integrated divisions — Aggregates and Concrete, Groundworks and Civil Engineering, and Property Development — the company is one of Kent's largest family businesses, with turnover exceeding £150 million (2023) and 550+ employees. Aggregates and Concrete is the primary revenue engine, running two quarries (Hermitage Quarry near Maidstone and Blaise Farm Quarry in West Malling) and six concrete plants across Kent, with annual capacity of up to 2 million tonnes of aggregates and 250,000 cubic metres of ready-mix concrete following the 2021 acquisition of four Cemex UK plants. The company is the only remaining active supplier of Kentish Ragstone, a heritage building stone used in the Tower of London, Westminster Abbey, Rochester Cathedral, and Canterbury Cathedral, giving it a defensible monopoly-grade position in the heritage restoration niche.

Underlying technology centres on quarrying and aggregate processing at industrial scale, including a £5 million barrel and binder installation at Blaise Farm — the largest of its kind in the UK — and a three-year quarry electrification programme combined with hydrogen-powered plant trials in partnership with JCB, Ryze Power, and the Lower Thames Crossing project. Site engineering uses Leica Total Stations and GPS; fleet operations are managed through Truckfile; concrete delivery is tracked via MOBILEticket. Certifications span ISO 9001, ISO 14001, and ISO 45001.

The business model is project-based B2B across three revenue streams: aggregates and concrete sales (priced by volume/tonnage via dedicated sales teams), groundworks and civil engineering contracting (won through competitive tendering and long-standing relationships with main contractors including ISG, McLaren, Buckingham Group, and TSL), and property development (mixed-use commercial and industrial sites including Eclipse Park in Maidstone and the planned Swatland Farm business park). Customers are predominantly enterprise — main contractors, developers, and infrastructure clients — with major projects including the GLP/Magna Park Lutterworth logistics park (£20M+ package), the Crown Bevcan Delta Park facility (£12M+ package), and enabling works for East Anglia Three offshore wind. The company operates exclusively in Kent and the South East of England, with no international footprint.
