Steri Spray walked into the Den back in Series 5 with a UV sterilising system for shower heads, and it is one of the rarer Dragons' Den stories that has a genuinely tidy ending. The short answer is yes, the business is still trading, and its patented technology is now sold commercially through a specialist water treatment company in Hertfordshire.

The Short Answer

Steri Spray is still in business. The product does not have a standalone consumer website or an Amazon listing, which might make it look dormant if you only search casually, but the technology behind it is very much alive. It is now marketed as Steri-Spray Showers through Helmore Water, a commercial water treatment supplier based in Baldock, Hertfordshire.

That is not unusual for a business-to-business product like this one. Legionella control equipment for hospitals, care homes and commercial buildings does not need a flashy direct-to-consumer storefront. It needs contracts, certification, and a sales team that talks to facilities managers, and Steri Spray has all three.

The Pitch

Steri Spray appeared in Series 5, Episode 6, pitching a UV sterilising system designed to eliminate bacteria, including Legionella, from shower heads at the point of use. The category sits under fashion and beauty in our index, though the product itself is really a piece of health and safety engineering wearing a shower fitting.

The founders asked for £145,000 in exchange for 40 percent of the business. That is a steep equity slice for the money, the kind of split that usually signals either a founder who badly needs the cash and the credibility, or a product that needs serious capital to get past prototype stage and into commercial production.

The Deal

Deborah Meaden and Theo Paphitis teamed up and backed the full ask, putting in £145,000 for the 40 percent stake on the table. A joint deal between two Dragons on a full-price ask is a strong signal. Neither had to negotiate the founders down, which suggests both saw enough in the product and the market to move at the number on the table.

Paphitis brought retail and manufacturing scale from his background running Ryman and Robert Dyas. Meaden brought her instinct for products that solve a real, provable problem rather than a nice-to-have. Legionella prevention is squarely in the second category. Building owners are legally obliged to manage the risk, which gives a product like this a built-in, non-discretionary market.

That legal backdrop matters more than it might for a typical consumer pitch. Under UK health and safety law, anyone responsible for a workplace, healthcare setting, or rented residential building has a duty to assess and control the risk of Legionella bacteria in water systems. A product that helps meet that legal duty is not competing for discretionary spend the way a kitchen gadget or a fashion item is. It is competing to be the preferred way a facilities manager discharges an obligation they cannot simply skip.

What Happened After the Cameras Stopped

Getting the money is the easy part. The hard part for a niche B2B health and safety product is getting past the pilot stage, getting certified, and getting into the specification documents that facilities managers actually use when they choose water treatment suppliers.

Steri-Spray Showers cleared that bar. The technology has been tested and certified by NSF, confirming it meets recognised safety and efficacy standards, and the company describes its showers as the world's first and only commercial showers that actively eliminate Legionella bacteria at the point of use. That is the kind of independent verification that matters far more in this market than a catchy tagline.

The product is now positioned as part of a wider portfolio under Helmore Water, sitting alongside other commercial water treatment products aimed at hospitals, care facilities, gyms, and other buildings where Legionella control is a legal requirement, not an optional extra.

That trajectory, from a consumer-facing Dragons' Den pitch to a specialist B2B water treatment product, is not the path most viewers expect when they watch a deal close. But it is a genuinely common one for products that solve a real technical or regulatory problem. The route to market for equipment like this runs through facilities contracts and compliance certifications rather than shopfronts, and Steri Spray appears to have found exactly that route and stuck with it.

Where Things Stand Now

Steri Spray pitched in Series 5 for £145,000 at 40 percent, and Deborah Meaden and Theo Paphitis backed the ask jointly. Years on, the underlying technology is still commercially available, now sold as Steri-Spray Showers through Helmore Water in Baldock, Hertfordshire.

There is no consumer-facing shop and no Amazon page, because that was never really the market. If you are a facilities manager weighing up Legionella control options, this is a business you can still call. That is a good outcome for a product that started as a five-minute pitch in front of two skeptical investors nearly two decades ago.
