If Nordwestblock was a thing, a real thing, then what are the implications of Low Country Beakers storming the beaches of Britain?
I'll put money on the table that Islanders spoke a language akin to the big, Tang-colored area in the map below. Linguists studying the proto-historical Low Countries up to the Elbe don't seem too keen on it ever having been part of the Celto- or Germano-spheres.
Different solutions have been suggested, but the most plausible is something kind-of... Venetic-ish.

The swift Urnfielders seem plausibly porto-celtic, or at least they roasted the European landscape in advance of the swifter Iron Age Celts. I would assume that the Celtic spoken in the Islands today has a heritage in that epoch, maybe as late as the LeTene era, but probably around the time cremation becomes the fad.
