Having google pictured "Dracaena" the one that looks the best match i've seen so far is a "Corn Plant 'Massangeana' Dracaena fragrans"

The one in the picture looked much healthier, the leaves are variegated & and resemble the same shape. If the lower leaves had'nt been demolished by Bob the builder & i had been taking better care of it then i think it would look the same. I think I'll wait for the flowering stage to complete then chop the top and start again taking much better care of it this time.
