Trying to clear a twenty year old compost heap riddled with
ivy and couch grass.

There is a old compost heap in our garden covered in weeds, we have been
here 4 years and I have not touched it as I thought it would not be any
good now, maybe I am wrong?

You could well be. Compost usually stays worth using for at least
that long - even when very long in the tooth, it makes perfectly
good potting compost for most plants.

The best rule is to look at the state of the weeds growing on it.
If they are healthy and vigorous, then it is good stuff :-)
