An Overview

GSI is a broad line distributor which offers a complete sourcing solution, with an extensive product profile ensuring a total purchasing strategy.

GSI was founded in 1994 as a distributing firm specialising in LED and Opto products. Growing rapidly, GSI soon began to broaden its product range, branching into discrete semiconductors and transient suppression, surge protection and specialising in supporting the rail and service industries.


With core franchises such as Littelfuse, WJ Furse, Diotec, Zymax, Cherry, Phoenix Contact and ABB GSI are able to service a wide customer base in the UK and off shore.

Our sales team have exceptionally high product knowledge and can support our customers from ‘design in’ all the way through to distribution. We can work closely with our manufacturers to ensure a solid and problem free supply chain from receipt of order to direct site deliveries. We have a technical team who can support engineers directly and pride ourselves on our quick response time to site/project concerns.

An expanding part of our portfolio is surge protection – we now represent four key surge protection manufacturers all based here in the UK from WJ Furse (Thomas and Betts) through to more specialised manufactures such as PD Devices, Zymax and Advance Electronics (AEL Group). Call us today and speak to one of our trained advisors who can discuss your individual needs and recommend the best product range to suit your needs.

Along with our sister website and buying portal we are able to offer a full range of franchised and excess stock from our extensive warehouse based in Stockbridge Hampshire.
