Welcome to SEP, manufacturers and suppliers of a range of specialist products for the fire sprinkler industry. SEP was founded in 1991, establishing itself as a market leader in the design and manufacture of specialist fire protection products. Originally based in Sale, Greater Manchester we moved to new premises in 2010 due to the requirement for greater production and warehouse facilities. We moved again, to our current premises (Cheadle, Cheshire, southern M60), in 2017 following further growth and to prepare for the launch of our first ever LPCB-approved product, the ZONE GUARDIAN. Our stock and range of compressors, flow switch test devices, pump initiation boards, booster pumps and associated accessories is constantly expanding - we regularly work with customers to manufacture bespoke solutions, often unique in the market.
