In the UK your ‘warranty’ is ALWAYS with the person or company who sold the goods to you. If you buy something as a PRIVATE customer (and you’re not pretending to be a business) then you are protected by the Consumer Rights Act 2015 and any warranty offered by a manufacturer is always IN ADDITION TO your rights under the CRA 2015. Because UBNT have chosen to set up a UK specific web store they are subject to the CRA 2015 and will have to abide by them.
Or you could save a few quid and buy something from a suspiciously cheap seller on Facebook.
I'm well aware, but unless the product was drastically cheaper from a third party, I'd rather not have the argument, regardless of if I'll win it or not.
