As far as I know, Gateshead is not in Manchester, nor is, I am told, Austin or any other part of Texas.
Rav Schneebalg (aka The Ruv) is Rav of the Machzikei HaDass communities, which officially do not sanction the Eruv, but many of the shuls do allow. I believe Belz do allow the eruv. I also heard that The Ruv’s family used the eruv publicly recently.
But USING OR NOT USING THE ERUV DOESN’T MAKE IT FRUMMER OR NOT FRUMMER!!! It is your Rav’s psak that allows you to use an eruv. And if you are frum, you follow your Rav.
