It's Soapwort (Saponaria)! Can't believe the hints didn't give it away
Apparently it can spread quite easily once you have it established, which is handy as I'm actually contemplating planting a load in the garden and using it for soap!
I've found a double-flowered variety of Soapwort near to my house recently, Bouncing Bett as it's known: http://wildflowerfinder.org.uk/Flowe...t/Soapwort.htm
The seeds were a pain in the backside to germinate, I'm not sure if I just had a bad batch or not but I've got a handful of small plants on the go now.
horse chestnut and snowberry are also full of saponins
