It's presently around 4' 6" tall, and looks like a dark green spiky
thistle. However, there is no sign of any of the usual thistle seed
heads. Can anyone tell me what it really is?

Or Spear thistle (Cirsium vulgate)?

Yes - that definitely looks more like it than the woolly thistle. Google
searches indicate that it can grow to 1.5m, but mine is more like 1.8 -
and it's still growing. However, I think it's now spending more time
forming seed heads.
