The show originally started at 9pm, with episodes running from about an hour up to nearly two hours for special events like the launch. Recently, the Wednesday episode time moved to 8pm to avoid clashing with other popular shows. The show does not air on Fridays or Saturdays, but repeats and catch-up streaming on Channel4.com are available. The schedule has seen occasional changes such as no airing on certain Thursdays and some episodes shifting start times due to other programming like "The Celebrity Traitors." In summary, new episodes of Married at First Sight UK are broadcast five nights a week: Sunday, Monday, Tuesday, Wednesday, and Thursday, with the current schedule indicating:

• Sunday to Tuesday: 9pm start
• Wednesday: 8pm start
