You vote on Big Brother through the official broadcaster’s voting platform, usually via a website and/or app, during specific voting windows announced in each episode. The exact steps and links depend on which Big Brother version (UK, US, Naija, etc.) and which country you’re in.

Basic way to vote

  • Go to the official voting page (for example, in the UK this is via the broadcaster’s main voting hub, and in Naija via the Africa Magic / Big Brother website).
  • Create or log into an account with your mobile number or email if required.
  • Wait until a voting window opens (the show will say “lines are now open/closed”).
  • Select Big Brother, choose the housemate to save or evict (varies by format), and submit your votes.

Online and app voting

  • Many recent versions let you vote free online, though your data/wifi charges still apply.
  • Official apps (Big Brother or broadcaster app) usually have a “Vote now” button that sends you to the same voting system in your browser.
  • You’re often given a fixed number of votes per mobile number per event (for example, a small bundle of votes each time lines open).

Phone/SMS and limits

  • Some regions still offer paid phone or SMS voting, or switch to paid phone short codes if there are technical problems with online voting.
  • There are strict vote caps per device/number, and any unused votes in a given window usually expire when that window closes.

Tips for your specific show

  • Check what country/edition you’re watching (e.g., Big Brother UK on ITV, Big Brother US on CBS, Big Brother Naija on Africa Magic) and visit the official site or the on‑screen URL given during the episode for the exact link and rules.
  • Make sure you’re using the current season’s instructions, because voting methods and rules can change from year to year.
