at the moment I'm trying to get the Parliament linked-data IDs in place - currently on about 5000 with an ID out of 13500 identified Acts, versus 17500 in the Parliament source data. Another 7500 matches (same short title + year + chapter number) just going in, so by the end of the evening we'll have an attached ID for pretty much all the extant ones.

Also, I have data for number of acts (Public, private & Local), 1660 - 1921, if you want to see what percentage are in wikidata.

Have started a talk page for the wikidata project page:
