Hi, I have been looking over this forum for a while, and thought i could be of some help on this particular thread, so finally decided to join.
Im not quite sure what you have here, or how to keep it, but my friend Gary over at the north wales reptile and raptor sanctuary definately will, and can either take in your stray lizard, or if you wish, give you some great info on how to keep it healthy.
his contact details can be found here:

hope that helps,
