We've had smart meters installed (don't ask!) and I'm not too sure on
whether or not the ribbed flexible connector to the supply is as it
should be. It looks a little stretched with that tight bend at the right
hand end.

Anyone with relevant gas installation knowledge care to comment?

That looks dreadful. It's easily solved but doing so is the job of the
installer.
