What Glazerite UK Group does
Glazerite UK Group Ltd is a UK-based B2B trade fabricator of uPVC and aluminium windows, doors, and conservatories, headquartered in Wellingborough with five additional manufacturing divisions in Peterborough, Bristol, Bolton, and Barnsley. Founded in 2000 and self-described as the UK's largest VEKA trade fabricator, the company sells exclusively to trade installers, commercial contractors, social housing providers, and education sector customers, with no direct-to-consumer channel. Its product portfolio spans casement, flush sash, vertical sliding, tilt-and-turn, fully reversible, and bay/bow windows, alongside composite, uPVC residential, aluminium bi-fold, heritage, French, and patio doors, conservatory roof systems, integral blinds, and curtain walling, all built on five primary profile systems (VEKA, Halo, Deceuninck, AluK, Cortizo) and supported by patented Timberweld® corner welding technology and Haffner machining equipment supplied through a 20+ year machinery partnership.
The company operates a quote-based, project-by-project hardware sales revenue model, pricing on specification, volume, and product configuration with no subscription component. Its go-to-market combines a regional field sales team of Area Sales Managers, an approved installer partner network, and comprehensive support services including marketing materials, white-label websites, technical specification assistance (notably VEKA's WinDoPlan calculation software for commercial projects), and account management. After a 2021 management buyout led by Group Managing Director Robert Brearley and four co-directors, the company has expanded aggressively, opening a sixth site in Barnsley in 2023, launching in-house aluminium fabrication in 2025, and entering adjacent product niches such as flood protection doors through a partnership with M3 Floodtec. Accreditations including Secured by Design, ISO 9001, PLC Scheme, and PAS 24:2022 support its participation in social housing, education, and commercial tenders.
