On the third leg of its tour around the UK, Dragons' Den: On Tour heads north.

Peter Jones drops in on Eddie Middleton, who managed to anger the Dragons before getting - and turning down - an offer of investment to produce his eco-friendly patio heaters.

Duncan Bannatyne rolls his sleeves up and goes window cleaning with his new investment UK Commercial Cleaning, whilst another Dragon spurned, Deborah Meaden, visits Naomi Timperley from Baby Loves Disco.

James Caan goes to see Martin Wadsworth, who couldn't convince the Dragons of the market for his slimline heated skirting boards, and Theo Paphitis catches up with young entrepreneur Vernon Kerswell from Extreme Fliers Toys, to see if he followed his fatherly advice - to go back to university and finish his degree.
