You can buy PTFE tape marked as suitable for gas. However, I was told by
a corgi registered plumber that it should not be used for gas! They
reckoned you should use gas jointing paste only. Any views on this?

I've heard of PTFE being used on copper compresion fittings, and joint paste
on malleable iron fittings, so I think both are acceptable in their own
ways. Joint paste is the way to go though, but only if you know you're
applying it properly.
