One-hit wonders in the UK

This is a list of artists who have achieved one number-one hit on the UK Singles Chart and no other entry whatsoever on the chart. The list uses the strict The Guinness Book of British Hit Singles definition of "one-hit wonder", a term also commonly used more loosely to refer to any act known primarily for one major hit.

A hit is attributed to the main artist given credit. If a single is released by two artists with the conjunction 'and' or 'versus' then both artists have equal billing (e.g. Jane Birkin and Serge Gainsbourg) and are both counted as having a number one (in this case "Je t'aime... moi non plus") whereas if the conjunction between two artists is 'featuring' or 'with' (or similar) then the first artist is considered the main artist for that hit, with the other artist listed being given a lesser billing (traditionally in these cases they would be additional vocalists or contributing instrumentalists, although in the 21st century it became common for the lead vocalist to be a 'featured' artist).

Artists who are classed as one-hit wonders within the past twelve months are not yet added to the list, as they may still follow-up their number one with another hit. A one-hit wonder from earlier who now go on to score another hit will be removed from this list.

This list is the opposite to the "Collaborations classified as one-hit wonders list" as this is artists who went to number one on their own with their only solo hit, however their only additional chart entries were with other artists.

The following collaborations are classified as "one-hit wonders" by Guinness Hit Singles because each of these particular combinations of artists had a single #1 hit with no other chart entries in this particular configuration. However, in each case, each of the participating artists had at least one additional hit separately. The latter editions of the Guinness Hit Singles book omitted this list. Examples of titles which were eligible for inclusion include the following

Please note, this list is not exhaustive.

The following is a list of aggregate ensemble groups. These are usually put together for charity purposes. The ones listed below are one-hit wonders in their respective line-ups, but each is made up of several chart artists. The following line-ups have all reached number one in their only hit under these umbrella group names:
