Yes, flavus not maculatus

You're quite right. The large pale blotches (rather than small speckles) on a variable but mostly khaki or orange-brown background, and the lack of a pale stripe along the keel (faint ridge down the middle of the back) all suggest Irish Yellow Slug L. maculatus rather than Yellow Slug L. flavus. It's quite widespread in Britain now, seeming to have replaced L.flavus in many places in the last 20 years, it's usually abundant where it occurs, and often found in gardens.
