Is Electro Expo Still in Business? (2026 Update)
Peter Moule pitched Electro Expo in season 5, offering a simple plastic housing, branded Chocbox, designed to safely enclose electrical connections made with screw connector strips, protecting them from damage and accidental contact.
Yes, still in business, and by most accounts one of the quieter long term success stories of the whole show. The company behind Chocbox has been registered continuously since long before its television appearance and remains active today.
What they pitched in the Den
Electro Expo struck a deal of £150,000 for 32% of the business, backed jointly by Duncan Bannatyne and James Caan. Bannatyne has since described it as one of his best investments from the entire run of the programme.
The pitch was unglamorous by design: a plastic box that snaps around a bundle of screw connector strips to stop them being accidentally touched or knocked loose, the kind of small, boring safety fix that electricians end up buying in bulk without a second thought.
Are they still trading?
Companies House lists Electro Expo Ltd, company number 01577246, as active, incorporated all the way back in July 1981, decades before the Dragons' Den pitch. There is no dissolution date on record.
The Chocbox product itself, now also sold under related brand names like Vimark and Greenbrook Chocbox, was in stock as a junction and connector box on Screwfix's website when we checked, suggesting the product line has remained in active retail circulation for well over a decade since the original deal.
Can you still buy it?
Yes. Chocbox and closely related connector box products were listed on Screwfix at the time of our check, sold under brand names including Vimark and Greenbrook.
Toolstation and Wickes have both been reported as retail partners for the product historically, so if a specific listing has moved, those are sensible places to look next for the same style of connector box.
