Newly published accounts reveal Tarmac suffered a £36m profit impact following the sale of civils firm Alun Griffiths Contractors.
Materials and civils giant Tarmac has seen its UK profit impacted by nearly £36 million following the sale of Alun Griffiths Contractors. The business was sold back to its founder, Alun Griffiths, in May 2025 for an undisclosed amount, according to recently filed corporate accounts.
The financial figures highlight the significant restructuring costs and financial hits large materials suppliers face when offloading non-core civil engineering divisions. Tarmac remains one of the largest suppliers of heavy building materials, aggregates, and asphalt across the UK market.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
Financial losses at a corporate parent level do not mean immediate price hikes at the local merchant yard. However, material giant balance sheets eventually dictate trade pricing strategies, rebate structures, and regional delivery networks. Tradespeople buying bagged cement, aggregates, or ready-mix through regional builders' merchants or stockists like Wickes and Travis Perkins should not see sudden availability issues, but it reinforces that heavy building material suppliers are actively trimming unprofitable civils arms to protect core manufacturing profitability.
As major supply-side firms streamline operations, trades and civils subcontractors should keep an eye on contract terms and material availability. Corporate restructuring among dominant suppliers often leads to a sharper focus on core building products, ensuring ongoing supply stability for standard building lines.
