Five Guys is not "3x any other burger chain", that is lunacy. I live in London and eat burgers a lot. Chains like GBK ("Gourmet" Burger Kitchen, of course just another mid-market chain, not gourmet in a classical sense), Honest Burger, Byron Burger, Black Bear Burger, Burger & Beyond, Patty & Bun, other imported USA chains like Shake Shack, and others. They're all popular places to go for a burger, and they're as or (typically) more expensive than Five Guys. You can find much more expensive burgers too. And yes you can find cheaper burgers, but not very nice ones (I do not enjoy Big Macs at all, and for that matter I don't like Five Guys either, but I can get something I like for their prices). I would say what I regard as a "decent" burger here has gotten much more expensive.
