Neither thyme nor ivy but sorry I don't know what
It might be fat hen (a weed) - the stuff gets everywhere around here. The good news is that it is edible. The leaves do look a bit too shiny though, so not 100% sure. See this photo:
I don't think it's fat hen but something in that family seems likely
Thanks for your help ive included another image as still getting to grips with posting images, thanks again
Fat Hen has a cultivated relative called Good King Henry that was once a popular vegetable, I never seen it myself but could be a possibility.
Can't see it terribly well but it reminds me a bit of a young thorn-apple plant - often growing from spillage from bird seed - not certain about that but there are similarities - we'd have to wait for a flower to be certain.
