1977 is the first year for which "full year" UK year-end charts exist – in order to be published in the year's final issue of Music Week and to be broadcast on BBC Radio 1 on New Year's Day, the collection of sales data had a cut-off point sometime in early December each year. This continued to be the case until 1983, when Gallup took over the compilation of the charts from the British Market Research Bureau (BMRB) and automated the data collection process, which meant that sales could be tabulated right up until the end of the year and still produced in time for the Radio 1 broadcast. However, from 1977 to 1982 (with the exception of 1979), BMRB produced updated charts a few months later which included the missing final weeks' sales for each year.

The tables below include sales between 1 January and 30 December 1977: the year-end charts reproduced in the issue of Music Week dated 24 December 1977 and played on Radio 1 on 1 January 1978 only include sales figures up until 10 December 1977.
