Graphical summary
Poll results
Poll results are listed in the table below in reverse chronological order, showing the most recent first, and using the date the survey's fieldwork was done, as opposed to the date of publication. If such date is unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. When a specific poll does not show a data figure for a party, the party's cell corresponding to that poll is shown empty.

Notes
- HT Identifies multi-scenario opinion polls which hypothesize on a high turnout.
- LT Identifies multi-scenario opinion polls which hypothesize on a low turnout.
- EF Identifies polling firms that explicitly show their top-line results projected over "all electorate" figures, that is, not excluding the calculated abstention rate. This is in contrast to "valid votes", which is the most frequent method of vote projection by opinion pollsters and which do account for blank ballots. In order to obtain data comparable to both the official results projected over "valid votes" as well as projections from other pollsters, a rule of three is applied, disregarding the projected abstention rate. The results of such calculation are shown instead.
- CV Identifies polling firms that explicitly show their top-line results projected over "candidacy votes", that is, votes going for political parties, excluding blank ballots. This is in contrast to "valid votes", which is the most frequent method of vote projection by opinion pollsters and which do account for blank ballots. In order to obtain data comparable to both the official results projected over "valid votes" as well as projections from other pollsters, a rule of three is applied, considering a comparison between 2011 election results calculated both over "candidacy" and "valid votes". The results of such calculation are shown instead.
Seat projections
Opinion polls showing seat projections are displayed in the table below. The highest seat figures in each polling survey have their background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. 176 seats were required for an absolute majority in the Congress of Deputies.
