What Bilco does

Bilco UK Ltd is a wholly owned Bury St Edmunds-based subsidiary of Quanex (formerly Tyman Plc / ERA) that designs, manufactures, and distributes specialty building access products for the UK and Irish commercial construction markets. Its core offering comprises aluminium roof access hatches (including the S-50TB, E-50TB, GS-50TB and CS-50TB series plus the patent-pending S-50TB thermal-break variant), Natural Smoke and Heat Exhaust Ventilators (ESW-50REM, UDF-50REM, SKY-1M sliding skylight), aluminium floor access doors (J-AL/JD-AL drainage, TER/TRD architectural, K/KD interior), BS 4211-compliant fixed vertical ladders and retractable ladder options, and a complementary safety-products line including the registered LadderUp™ safety post, Bilguard railings, and roof edge protection.

The business operates a specification-driven, enterprise go-to-market model: architects, building services engineers and consultants are addressed pre-tender through RIBA CPD-accredited seminars (over 4,000 specifiers reached in 2023), BIM and CAD libraries on NBS Source and the National BIM Library, NBS specifications, and RIBA Product Selector listings, with Technical Account Managers and a Sales Specification Manager providing direct technical advice and quotation-based pricing on a per-project basis. Products are sold under bespoke quotations determined by size, hardware (e.g. stainless 316, keyed locks, powder coating, fire rating) and minimum order quantity for custom finishes, generating multi-year specification-to-procurement revenue cycles rather than transactional pricing.

Together with acquired sub-brands Howe Green (floor access covers, linear drainage, acquired March 2017) and Profab Access (wall and ceiling access panels), Bilco UK presents a consolidated 'Access 360 – Safe Access All Areas' proposition to specifiers and contractors in healthcare, education, heritage, transportation infrastructure and commercial developments, supported by ISO 9001 and ISO 14001 accreditation (Lloyd's Register), Constructionline Approved status, NFRC membership, CE marking, and compliance with BS EN 12207/12208/12210, BS 9999 and EN 12101-2. Channel reach was extended in November 2023 via a Crossflow partnership covering both the Republic of Ireland and Northern Ireland, and the business now operates under the global backing of Quanex while retaining Managing Director James Fisher as the operational leader.
