ISA-UK powered by the BSGA (formerly the British Sign & Graphics Association) is the leading trade organisation for the Sign Industry in the United Kingdom. Our history dates back 100 years to the 1900s when a group of leading sign makers formed the Master Sign Makers Association (MSMA) with the aim of promoting the sign industry and defending its interests against adverse legislation with a ‘Signs Defence Fund’. ISA-UK is the only UK trade association dedicated to the sign industry. All our members are vetted prior to being allowed to join. And once accepted they sign up to the ISA-UK Code of Practice which demands high standards of workmanship, quality, professional commercial practice, customer service and aftercare. If you are looking for a signmaker to undertake anything from a national brand roll-out the production or a facia for your shop, make sure the one you pick displays the ISA-UK symbol.
