Big Brother

• Should a contestant be evicted from the house, removed by Big Brother or leave of their own accord, they will be settled as a loser. Should that same contestant be re-admitted at a later date, they will be treated as a new contestant and previous bets will not stand.
• Eviction markets apply only to official Channel Four/Five evictions. Any contestant leaving the house of their own accord or removed by Big Brother will not be treated as the next evictee for betting purposes. Betfair reserves the right to void all bets placed on an eviction market should the initial line up for eviction be changed. Others may be added to the market at any time.
• Betfair is not responsible for the way in which Channel Four/Five conduct the show. Any late changes to methods of eviction, addition or subtraction of housemates or any other factors affecting the market are beyond our control.
• Any disputes concerning any market will be referred to Channel Four/Five for clarification; their decision will be treated as final.
• Betfair reserves the right to suspend any market at any time.
• For the purposes of our markets, we will define an eviction as the permanent expulsion from the house of contestant or contestants. Therefore, fake evictions will not be considered as winners. Therefore any bets placed on a stipulated eviction (e.g. first) will run until a person is seen to egress the house with no immediate prospect of return.
• Betfair reserves the right to apply a dead heat reduction on any event where more winners are declared than were originally specified.
• In the event of the series been cancelled before an official winner is declared, bets will be settled as a dead heat between the contestants that have not been eliminated. Outright bets on contestants already eliminated will be treated as losing selections.
  

Christmas Number One

• Bets placed on the next Christmas number one will be settled on the basis of the UK Chart declared by the Official Charts Company.
• For the purpose of this market, featuring artists do not count. Whether or not a song is considered to be a duet or, alternatively, a song which includes a "featuring artist" will be determined by officialcharts.com. In particular, it will be determinative if officialcharts.com includes the word "featuring" or the abbreviation "FT" (or similar) before an artist's name. Where a duet has a realistic prospect of achieving the Christmas number 1 spot, we will endeavour to offer a selection in respect of that duet (for example, Calvin Harris and Sam Smith).
• Where multiple versions of a particular artist's song include different secondary artists (and those multiple versions are considered by the Official Charts Company to represent a single entry), it is only the primary artist that will be deemed, for settlement purposes, to be included in the entry. For example, the official Christmas Number One in 2017 was Ed Sheeran's "Perfect" (albeit that such song achieved its placing as a consequence of separate versions which included Beyonce and Andrea Bocelli). In such circumstances, Ed Sheeran alone would be considered to have achieved the official Christmas number one.
  

Other Novelty Markets

• TV Specials: If a winner is not declared for the series in question then the outright markets will be made void.
• The betting rules for other novelty markets are often very specific and will usually be displayed on the same page as the betting market in question.
