SPI is a signage company based in Greater Manchester. We design, manufacture, install and maintain signs and graphics for clients across Manchester, the North West and the whole of the UK.
Our own team handles every stage, from the first survey to aftercare. We are ISO 9001, ISO 14001 and ISO 45001 certified and accredited as a Principal Contractor with SafeContractor.

Our Mission
SPI was set up to bring clarity and trust to the signage industry. We are open with our clients about how every job will be delivered, what it will cost and who will do the work.
Our team brings over 250 years of combined experience in signage, and our senior leadership team has built a culture of listening carefully, responding quickly and working hard.
Most of what we supply is made in our own 3,000 sq ft workshop in Bolton. For specialist processes and the largest structures we use a carefully selected supply chain, and we are upfront about it, managing every stage ourselves.
Our qualified project managers take on the role of Principal Contractor on site, so safety, programme and coordination are taken care of for you.
What we do
We make and install signs and graphics that help organisations be seen, found and remembered, in buildings, public spaces and customer facing environments.
That includes illuminated signage, built up letters, fascia and projecting signs, totems, wayfinding, interior signage, tactile and Braille signage, digital signage, printed graphics, hoardings and bespoke architectural pieces.
We cover design, manufacture, installation and maintenance, working nationally from our base in Greater Manchester.
Our Commitment
Quality, creativity and professionalism sit at the core of everything we do. Whether a project is a single sign or a national rollout, it gets the same care, the same attention to detail and the same team from start to finish.
