What IDSystems does

IDSystems, registered as Innovative Design Systems Limited (also trading as Sunflex UK), is a Norwich-headquartered UK glazing specialist founded in 2000. The company designs, supplies, and installs premium aluminium glazing systems — including sliding doors, bifold doors, slide-and-turn doors, windows, roof lanterns, glass roofs, internal glass partitions, balustrades, and front doors — for residential and commercial customers. Its flagship proprietary product is the award-winning theEDGE2.0 ultra-slim sliding door, with 20mm sightlines and panels up to 3m wide, complemented by exclusively distributed German-engineered SUNFLEX aluminium systems (SF55, SF75eco) and a proprietary vistaline slide-and-turn solution. The product range is custom-made-to-order with precision-engineered tolerances and is installed by directly employed fitters across the UK.

The company operates a project-based, quote-driven revenue model: customers submit project specifications (sizes, colours, configurations, handle options, architects' drawings) and receive a tailored quotation, with no public list pricing. Revenue is generated primarily through one-time custom glazing product sales and installation projects, supplemented by after-sales service. IDSystems serves three principal customer segments — homeowners undertaking extensions, renovations, self-builds, and conversions; architects and specifiers (supported by RIBA-approved CPD training and NBS Source Partner integration); and builders/contractors — with a secondary commercial client segment addressed through a dedicated commercial website.

Go-to-market combines a showroom-led direct sales motion (Norwich HQ, Chelmsford, Central London Building Centre, Cambridge), digital content marketing (website, blog, case studies, video), trade-event presence (Grand Designs Live), and architect/specifier engagement via RIBA CPD programmes. The company is privately held with no disclosed external investors, has no parent company or subsidiaries, and operates as the legal entity registered in England and Wales. IDSystems has completed approximately 30,000 projects over 25 years, holds FENSA, CE, RIBA CPD, and NBS Source accreditations, and maintains a 4.8 Trustpilot score across 126 reviews.
