Who We Are

ISA-UK is the only trade association
for the signage industry within the United Kingdom.
We seek to raise industry specific standards, communicate best practices,
and increase and support the development of a diverse and inclusive signage community.
Our History


Our history dates back over 70 years to the 1930s 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’.


In the 1970s, the MSMA changed its name to the British Sign Association (BSA) with the intention of becoming more inclusive and opening membership up to the ever increasing number of smaller sign making businesses.


At the start of the new millennium, in recognition of the advances in technology and the involvement of sign businesses in delivering a constantly expanding range of products and services, the association again re-branded to the British Sign and Graphics Association (BSGA).


In July 2018, the BSGA agreed an affiliate programme with the International Sign Association (ISA) based in Alexandria, Virginia, USA which came into being as the ISA-UK (Powered by BSGA) on 1st January 2019. 

The International Sign Association is a leader in shaping and developing the sign, graphics and visual communications community worldwide. Through their strategic partnerships, ISA provides its partners and their members access to programs and services designed to grow their business.
