It's a newt. It'll freeze when if feels threatened and only move on when it's all peaceful again.
They're out and about just now, feeding up before they burrow and overwinter. They don't hibernate as such, they just find somewhere damp that won't freeze. Compost heaps, under leafy piles, in muddy banks, or in gardens under sheds, planters and so on.
They'll roam quite a distance from the pond or burn they use for breeding, but they seem to mostly go back to the same one. They're in the burn along side our garden as well as in every garden pond in the street. I quite like seeing them there, it can be interesting going out with a torch just after dark in late Spring and seeing just how many of them there are in the pond.
These are some of the ones that Himself took of a little one last year.
