Married at First Sight is a British television programme where strangers start a marriage-like relationship with each other, meeting only minutes beforehand. Upon returning, they live together for a period of time, during which they meet at commitment ceremonies and choose whether or not they will continue their relationship. On 14 March 2021, Owen and Michelle from Series 5 became the first couple to celebrate their 1st wedding anniversary together.

On 24 November 2020, it was announced that the programme would move to Channel 4's sister channel E4 in 2021, and would use the format of its Australian counterpart following the highly successful broadcast of the latter on E4.

Following the success of Series 6, it was recommissioned for a longer 30-episode seventh series, and a 37-episode eighth series.
