List of best-selling singles by year in the United Kingdom

This is a list of the best-selling singles on the UK Singles Chart for each year. Note that the Number sold section denotes the number sold within the year, not in total, as very often the single continues to sell more in later years (and sometimes other singles released within a particular year will go on to outsell the year-end winner (e.g. Kylie Minogue and Jason Donovan's "Especially for You" (from 1988) ultimately outsold "Mistletoe and Wine")).^[1]
