About one fifth of the membership of the Company comprises Liverymen and Freemen who are practising glass artists and conservators.
Whilst admission to the Company does not include specific assessment of the applicant's work, many members are also Fellows or Associates of the British Society of Master Glass Painters (BSMGP) or of the Guild of Glass Engravers. Others may be United Kingdom Institute for Conservation (UKIC) Accredited Conservators.
Talented Award Winners of the Company often go on to establish their own businesses in architectural glass. Award winners may be granted the Freedom of the Company by Gift once they have shown to have established themselves in their careers.
All the practising artists and award winners welcome new commissions.
