About Us

With a background in specialist vehicle conversions, electrical installation plays a prominent part of our business. We recognised that enthusiasts, clubs and small businesses need to source smaller quantities of electrical installation parts for their projects. 

Following a number of successful years trading with our eBay shop, we have now increased the accessibility in sourcing the items that you require through this dedicated secure website, and in many cases reducing the cost of your purchases by not having to account for the numerous fees that would be encountered otherwise. We carry comprehensive stock and you can now purchase cable by the metre as well as on rolls of varying sizes, and to keep delivery times at a minimum, all items are dispatched within 24 hrs/next day, and will be sent out by Royal Mail 1st class Signed For post or courier for large/heavy items.

Please visit the SHOP to browse and order your supplies.
