Why would you want one?
Even in England/Great Britain GMT is just a local name for UTC these days.
UT1 is for astronomers, as well as a way to figure out when/if to

BTW, anyone want to bet how much (supposedly leap-second handling) gear
will fall down if we actually have to subtract a leap second?
