Have checked once again and its June 1947. If it helps this is a question that is in a quiz for Macmillan Cancer. Really puzzled on this one, seems google has finally let me down haha.

The 999 emergency telephone service was made available to London subscribers from 30 June 1937 and was later extended throughout the country

The University of London was consulted on the designation of teaching hospitals in June 1947
The Retail Price Index (RPI) was first calculated for June 1947 It was once the principal official measure of inflation. It has been superseded in that regard by the Consumer Price Index.
