Energy EGG pitched an energy-saving sensor gadget in series 11 of Dragons' Den, walked away from the investment it was offered, and the product it pitched is still findable on UK shelves and marketplaces today.

The Short Answer

Yes, based on current listings, Energy EGG products are still being sold. The sensor and its accessories continue to turn up through retailers including Amazon, eBay and Mankind, which is a reasonable sign of an ongoing, if modest, product line rather than a brand that quietly disappeared.

The Pitch

Founder Brian O'Reilly pitched Energy EGG in series 11, episode 11, in the Tech & Software category. The product was a motion sensor designed to tell the difference between an empty room and one with a person sitting still in it, then automatically switch off appliances plugged into it when nobody was actually there.

O'Reilly asked for £50,000 in exchange for 30 percent of the business, valuing the company at roughly £167,000, a pitch aimed squarely at the energy-saving gadget market that was picking up steam around that time.

The Deal, and Why It Fell Apart

Piers Linney offered the £50,000 investment on the show. As with a number of Dragons' Den pitches, the deal did not survive contact with the small print. Reporting from the time points to Linney's proposed investment conditions creating friction with O'Reilly's existing investors, and the deal broke down after filming rather than closing.

That is a familiar pattern for founders who already have other people's money in the business before they ever reach the Den. A Dragon's terms have to fit around agreements that already exist, and sometimes they simply do not.

What Happened After Filming

Energy EGG kept going without the on-air investment. The product, sold under the TreeGreen brand as well as the Energy EGG name, has continued to be listed by UK electrical and smart home retailers in the years since, and listings for the sensor and its power strip bundle still appear on major marketplaces.

It is not a brand that expanded into a household name, but it has held a steady niche among energy-saving accessories, which is arguably the more realistic outcome for a single-product gadget pitch than a dramatic growth story.

Where Things Stand Now

In short: Energy EGG asked for £50,000 for 30 percent in series 11, episode 11, was offered the deal by Piers Linney, and the investment fell through after filming.

The product itself has outlasted the deal. Based on current retailer listings, Energy EGG sensors are still being sold today, which answers the practical question most people searching for this company actually want answered.

A Product That Fits a Steady Niche

Energy-saving gadgets rarely become mainstream hits, but they do not need to in order to survive. A device like this appeals to a specific, repeat-buying customer, people who care about cutting standby power use in a home office, a spare room or a workshop, and that kind of buyer tends to keep coming back to the same trusted product rather than switching brands every year.

Being sold across marketplaces like Amazon and eBay rather than through a single flagship store also lowers the overhead needed to keep a product like this available, which likely explains why it has stayed on shelves well over a decade after its Dragons' Den appearance despite the investment falling through.
