London is served by the ports of Southhampton, Harwich, and Dover, but isn't a cruise port. Combined, Southhampton, Harwich, and Dover is the tenth most departed-from port, departure point of around two hundred and thirty sailings per year from Norwegian, Carnival, Cunard and more to Europe, the Mediterranean, and the East Coast.
On average sailings from London are fairly expensive compared to other ports. Cruises leaving from London during the peak months of winter and summer are significantly more expensive than the low seasons of spring and fall.
