There isn’t a catch—just straightforward maths. Because the system earns an average of £370 per month through smart trading, and your 5-year loan is roughly £254 per month, the system effectively pays its own way and hands you £116 in profit. You aren’t “spending” £12,000; you are simply diverting money you were already going to give to a utility company into an asset that puts cash back in your pocket.
