and Lisa Snowdon and Brendan Cole, Kimberley Walsh and Pasha Kovalev and Denise van Outen and James Jordan with 20. Of the above pairings, Snowdon and Cole, Flack and Kovalev, Tozer and Pernice and Roberts and Kovalev are the only pairings to receive straight tens for all of their dances in their respective series finals. Flack and Kovalev, Tozer and Pernice and Roberts and Kovalev are the only pairs to receive three sets of perfect 40s in the final. Of these couples, Roberts and Kovalev and Flack and Kovalev also hold the records for the judges longest consecutive streak of 40s, with four, both stretching from the second performance of the semi-final to the end of the final. Meanwhile, Pernice holds the record for the most 10s received by a professional, with 98, whilst Ayling-Ellis holds the record for the most 10s received by a series champion, with 30. Roberts and Kovalev also hold the record for the best overall average score from the judges, receiving an average of 36.94/40 for their dances. Natalie Gumede and Artem Chigvintsev, and Danny Mac and Oti Mabuse follow, with averages of 36.88 and 36.62 respectively. Quentin Willson and Hazel Newberry hold the record for the lowest average score, with 8.0/40; they are followed by Susannah Constantine and Anton Du Beke and James Cracknell and Luba Mushtuk, both with an overall average of 12.0/40.

Whittle's Showdance has not been included as it did not receive the perfect score from Bussell, and therefore cannot be considered the same standard. Seasons having a maximum of 30 points (18) have been converted to a 40-point base. The Showdance has received the most perfect scores of any dance, with fifteen; however, if it is disregarded based on being a routine specific to the final, the Charleston has received the most perfect scores of the regularly performed dances, with eleven. Contemporary, Rock 'n' Roll and Rumba are the only dances to have
