I've had a good search online for this one but not having much success IDing it, any ideas?

I would say that it's a young larvae of a Fox Moth. By the later instars the brown hairy sections cover more of the top of the caterpillar, giving it a more familiar look - which may be what you've seen on the web.

Nice photo, by the way!

See below a link to a nice selection of photos of the Fox moth that show the different look of the caterpillar through the different instars:

Many thanks for the ID Michael.
Looks like a completely different beast by the time it reaches the final instar
