What Cornwall Glass does

Cornwall Glass, operating under the Cornwall Group holding structure, is a family-owned glass manufacturing and glazing business founded in 1978 and headquartered in Truro, Cornwall. The company serves trade, commercial, architectural and domestic customers through three operating divisions — Cornwall Glass Manufacturing, Cornwall Glass & Glazing, and Mackenzie Glass (acquired from Pilkington/NSG in 2017) — alongside the December 2023 acquisition of Forward Glass in Birmingham. Distribution runs through ten physical branches spanning Penzance to Bristol, a permanent presence at the National Self Build & Renovation Centre in Swindon, and the UK Glass Centre national e-commerce platform.

The group's core manufacturing capability spans toughened glass, laminated glass, double and triple glazed sealed units, fire-rated glass, ceramic glass, heritage/restoration glass, and decorative products including mirrors, splashbacks and balustrading. Production is concentrated across four manufacturing sites in St Austell, Plymouth, Highbridge and Birmingham, operating a total of eight toughening plants. Processing equipment includes Glaston tempering furnaces, Bystronic sealed unit lines, Bottero laminate cutting tables, CNC machining, waterjet cutting, heat soak testing and oversize unit manufacturing capability up to 4.2m x 2.7m. The 2024 capital programme adds £3M+ of Glaston capacity, a £6M Highbridge expansion, £1M at St Austell and a further £5M across plant, machinery, fleet and IT systems, alongside a bespoke Highway Software ERP/workflow platform.

Revenue is generated primarily through one-time sale of manufactured and fabricated glass products, supplemented by installation services via the glazing division. Pricing is quote-based and not publicly disclosed, determined per project through branch consultation rather than list price. The customer base is fragmented across trade professionals (sealed unit manufacturers, joinery firms, shop fitters), commercial projects (shop fronts, fire glass, architectural glazing) and homeowners (splashbacks, shower screens, balustrades). Forward Glass contributes £10M+ annual turnover; group revenue, manufacturing footprint and headcount all indicate a mid-sized UK regional glass fabricator reinvesting heavily in capacity rather than optimising for short-term margin.
