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.

If it _is_ spear thistle, and it's forming seeds, you need to do something.

It's on a list of weeds that you are supposed to destroy; you can be
fined if you don't after a notice has been served.

Letting it go to seed might be seen as a bad move. But make sure it is
that thistle, not one of the rare ones!

I think you mean it's forming flower heads, it has to flower before it
can form seed.
