What Alun Griffiths (Contractors) Ltd does

Alun Griffiths (Contractors) Ltd is a privately held UK civil engineering contractor headquartered in Abergavenny, Monmouthshire, founded in 1968 by Alun Griffiths. The company delivers infrastructure, rail and geotechnical projects across Wales, the Midlands and South West England, with project values ranging from £100k to over £100m. Its three service lines cover highways and bridges, utilities, coastal/river works, active travel, urban regeneration, rail infrastructure (including a full Network Rail Principal Contractor Licence), and specialist geotechnical services such as rock bolting, slope stabilisation, rope access and soil nailing, supported by 60 directly employed geotechnical specialists and a fleet of 100+ vehicles.

Revenue is generated through tendered civil engineering contracts under public-sector frameworks and joint ventures, including the Griffiths Farrans JV used for flagship projects such as the £60m Bristol Airport Public Transport Interchange. Customers are predominantly UK government and regulated-utility counterparties: Welsh Government, Network Rail, National Highways, Transport for Wales, Welsh Water/Dwr Cymru, Western Power Distribution and various local authorities. Pricing is project-by-project and not publicly disclosed, with long-term framework agreements (e.g. Swansea Highways Partnership up to £20m over four years) providing recurring revenue alongside one-off tenders.

Following its 2018 acquisition by Tarmac (CRH plc), the company was reacquired on 8 May 2025 by Grosmont Ventures, led by founder Alun Griffiths and long-standing senior colleagues, returning it to independent ownership. The firm is pursuing a stated post-restructuring strategy of refocusing on core Welsh and West-of-England markets, improved project selection, investment in people and systems, and digital/sustainability initiatives including the PODFather electronic ticketing system and a net-zero-by-2030 commitment. Operating geographies remain regional; no global footprint is claimed.
