Mercury Glazing Supplies

What Mercury Glazing Supplies does

Mercury Glazing Supplies Ltd is a UK-based specialist fabricator of PVC-U and aluminium windows and doors, founded in 2002 and headquartered in Gloucester, with a registered office in Nailsworth, Gloucestershire. The company manufactures a wide range of trade and homeowner products across three Gloucester production facilities, employing over 60 trained staff; product lines include PVC-U vertical sliding sashes (fully welded and mechanical joint variants), aluminium casement windows (Alitherm 300/400, Heritage, Vertical Sliding Sash, Flush Sash), aluminium doors (Smart Signature, Visofold 1000 bifolds, Visoglide Plus sliding, Designer Doors, Aluspace internal screens), curtain walling, and lantern lights/rooflights. Mercury uses licensed systems from Spectus, Smart Systems, and Jack Aluminium Systems, and holds FENSA registration, Secured by Design membership, and PAS 24 compliance on its PVC-U sash windows.

Mercury operates a quote-based project revenue model across three customer segments: trade installers and contractors as the primary channel (direct sales with estimating support, marketing materials, and onsite delivery), residential homeowners seeking bespoke replacements, and commercial and public-sector clients including universities, colleges, and new-build developers. Pricing is bespoke per specification, with window units ranging £150-£600+ and whole-house projects £5,000-£15,000+. Distribution is UK-domestic only, with collection and full-site delivery options, supported by content marketing, project case studies, and industry accreditations as trust signals.

Operational capability is the company's primary lever: a 50% production facility expansion and acquisition of a third manufacturing unit in 2023, alongside recruitment of a Manufacturing Manager with prior lean manufacturing expertise, position Mercury to scale throughput while maintaining quality. Revenue is concentrated in the UK fenestration trade channel, with no disclosed external funding, suggesting organic, founder-led growth at a moderate pace against a Part L regulatory tailwind.
