Yes, Cunard will offer shore excursions from Southampton for passengers continuing on the round trip back to New York. Here is a link to a page on Cunard's web site showing a list of the possible shore excursions that might be offered from Southampton.
Be advised that Cunard most likely will not offer all of those listed excursions. The specific excursions that will be offered on your voyage should show up in your voyage personaliser approximately 12 weeks prior to your departure date.
Just to give you a couple data points from crossings we did a few years ago, in November 2015 Cunard offered excursions to Stonehenge, Windsor Castle, and Beaulieu. In August 2016 they offered the excursions to Stonehenge, Windsor Castle, and Winchester.
Following up on my earlier post to provide another data point about Cunard shore excursions from Southampton. Our upcoming 21-day round trip voyage from New York on QM2 in June 2018 (including a voyage to Norway) will have two days in Southampton (17 June and 24 June). For both of those days, Cunard is offering the following Southampton shore excursions in our Voyage Personaliser.
Cathedral City of Winchester
Royal Windsor Castle
Bombay Sapphire Distillery
Half day and full day private car/minivan tours of Southampton
Full day private car/minivan tours of London
When the excursions were first posted on Voyage Personaliser a couple weeks ago, there was also a listing for the "Southampton Titanic Trail" excursion, but that has since disappeared. The description for that excursion states "Your walking tour begins at Ocean Terminal". We are actually scheduled to be docking at the QEII terminal, so I wonder if that may have had something to do with that particular tour no longer being offered on our voyage.
