Thanks for your replies.

This machine doesn't round up the wins like others do. It just pays out 40p or 80p wins in 10p's. Any wins in whole £1's it pays out correctly in pound coins.

I've checked the hopper opto sensor, it was a little dusty so i cleaned it, but it still spills out the 10p's. I entered in to test mode and did a coin test before and after i cleaned the opto, with each press of the button it releases one 10p at a time as it should. So this makes me think it can't be the opto sensor. Am i missing something? i'm totally baffled about this one   If anyone else has some suggestions please do let me know.

Thanks for your responses and suggestions 

I've heard of these permits recently, but at £25 per machine i'm not sure it's worth it, as i'm only asking around £100 for Duet. 

If i was selling a machine for hundreds of pounds, then sure i would buy a permit to keep the gambling commission happy. 

I've tried Gumtree actually, but they also take it down. It's a shame it has become difficult for hobbyists to simply sell the occasional machine. 

I like the idea of listing a pile of old coins for sale and throwing in a free money box. I will have to try that soon if all else fails.
