The developer wrote to Mitcham Borough Council and suggested that since this road was next to the Victory pub, then the name of the road could be Trafalgar Close or Victory Close. The council disagreed, pointing out there were already similar named roads in the SW19 postal district. The council suggested Baltic Close, and the developer agreed, who suggested that the block of flats be named Oslo Court.

Note that the Victory pub has since been renamed a couple of times, and the current (as of Feb 2018) name is the Charles Holden, who was an architect who designed the nearby Colliers Wood underground station.
