I've just come across this. There isn't much pirate FOA's for this year on the website. Most of it is either about premium rate phonelines or amateur call signs.

FOA:

You asked for a list of all illegal broadcasters including their station names if known that
Ofcom were aware of during this period including any Ofcom were aware of but did not take
any action against. Please find below a breakdown for each year.

2008 - 0
2009 - 0
2010 - 0
2011 - 0
2012 - 0
2013 - 1
2014 - 0
2015 - 1
2016 (Jan-Mar) – 1

The names of the stations are being withheld under s44 of the Act. Section 44 of the Act
prevents organisations releasing information if another Act has said that it shouldn’t be
released, in this case, the Wireless Telegraphy Act 2006.

We have applied Section 38 (2) (c) (i) of the Wireless Telegraphy Act 2006. That is because
releasing details about the stations, such as names or frequencies, could be seen to be
facilitating their day-to-day operations.
