Duncan started with a single ice-cream van and built the Bannatyne Group of health clubs, hotels and spas. An original Dragon who sat on the panel through Series 12, he was known for blunt, no-nonsense questioning and a low tolerance for founders who did not know their numbers.

On the show, the numbers back up the reputation. Duncan Bannatyne has closed 14 on-air deals and put £995K of personal money behind them, which works out to roughly £110K per deal. That ranks Duncan sixth among the six main dragons for total dollars committed. It points to a selective filter. Duncan takes fewer swings, but there is more conviction behind each one.

Duncan's portfolio is not spread evenly. Business Services is the single biggest bucket at 29% of every deal Duncan has done, then food & drink and green & cleantech. There is a reason for that. Dragons write checks in the categories where their own contacts and experience actually move the needle, so Duncan's deal history doubles as a map of where that value lies. Founders pitching outside those lanes tend to have a harder time.

How Duncan builds a deal is as telling as the headline figure. Almost all of these were straight equity deals rather than royalties. Duncan teamed up with another dragon on 9 deals and went solo on 5. Duncan often joins forces to share both the check and the risk. The largest single commitment was £200,000 for 40% of Pro Waste Management Services.

Plenty of these companies outlived their episode. Umbrolly, Igloo and Razzamataz Theatre Schools are still on the market today and selling on Amazon. That is the real test of a Den deal. It is not the on-air drama that matters, it is whether the company keeps shipping product years later. Those are the ones worth a look if you are shopping rather than just watching.

It helps to zoom out. The six main dragons have committed very different totals over the years, and Duncan's £995K lands on the leaner end. Being the biggest spender and being the smartest investor are not the same thing, and some of the quieter dragons have backed the most durable companies. Volume tells you appetite. It does not tell you returns.

Below is the complete, regularly updated list of every Duncan Bannatyne deal that has aired, ranked from the biggest check to the smallest. Every figure reflects the terms as broadcast. Deals sometimes change, shrink, or fall apart once the cameras stop and due diligence begins.
