Chelmsford ship is a Specialized Concept Store so I'm pretty sure is an "authorised" dealer!
Just try reading it, it's all there in. English, we are not disputing you can take it to any dealer, but that is ONLY because it says you can, you have no automatic right that a warranty means that you can.
