Is it possible to get a "Y" adapter which plugs into the existing
lampsocket and then allows me to plug in two CFLs?

Never seen anything like that. Why not just change the fitting to a
multiple lamp holder that you like?

Look! I just made my own and you can plug kettles and washing machines
in too. I didn't know what to do with the green wire so I stuck it up
the hole and it went bang so I pulled it out again. I don't think it's
needed because everything works OK but the kettle makes me feel all
tingly when I pick it up.
