Hi Andy
Have posted it on my blog and my Flickr site.
My first thought is Sand Lizard but need more expert opinion. It could be an
escapee from a private collector, not sure what a Sand Lizard would be doing in
Findon, not much Heathland around there.
Illegally taken from the wild?

I would say that this is a young, but mature male Lacerta viridis - the eastern form found in and east of East Germany, Eastern Italy etc and throughout most of the former USSR.
A fair number were imported for lizard keepers in 2004 and 2005.
Given the apparent age of the animal it was almost certainly captive
bred -
which might also explain it walking into someone's house!
All the best
Chris
