Day Group

What Day Group does

Day Group Ltd is a UK family-owned construction materials and services company founded in 1947, headquartered in Brentford with a stated 500+ employees. The company handles over 5 million tonnes of construction material each year and processes more than 1.5 million tonnes of recycled aggregate annually, operating through four divisions: Day Aggregates (primary and recycled aggregates, bagged products, Ecoblend sustainable aggregate), Day Equestrian (specialist riding surfaces and equine aggregates), Day Contracting (turn-key water filtration and civil engineering for UK water utilities), and Day Glass Recycling (bulk post-consumer glass collection and maritime export to European manufacturers, with combined export capacity of 250,000 tonnes).

Day Group's core technology centers on rail-served depot logistics and aggregate processing: approximately 50 train loads per week move through the depot network, the Ecoblend product line blends up to 80% Incinerator Bottom Ash Aggregate (IBAA) with natural quarry material to Specification for Highway Works standards, and three IBA processing sites (Brentford, Greenwich, Avonmouth) operate alongside the new £20 million Wellingborough plant with 200,000 tonnes/year of IBA capacity under a long-term Encyclis feedstock partnership. The firm holds the Ecoblend trademark, ISO 9001/14001/39001 certifications, FORS Gold, CLOCS Champion, and multiple goods vehicle operator licences.

Revenue is generated through per-tonne aggregate sales to builders merchants and construction customers (the primary segment), project-based contracting fees (Day Contracting), glass collection and export fees (Day Glass Recycling), and equestrian product sales. Distribution is asset-heavy and direct: 200+ trucks making 1,000+ daily deliveries from 21 locations across the South of England, plus waste collection routes to Materials Recovery Facilities. Named enterprise customers include Thames Water, Gatwick Airport, Balfour Beatty, Bam Nuttall, and Montel Civil Engineering, with case studies spanning highways, rail infrastructure, airports, events, and water utilities.
