The new UK series will introduce a new group of singletons looking for love and their happy-ever-after but with a complete stranger. 

Similar to the Australian version, the couples will not be bound by legal marriages but instead will make lifelong commitments to one another in a wedding-like ceremony, in front of their friends and family, complete with dancing, speeches and cake. 

The real test will come after the celebrations are over and the couples must navigate their new relationship, going on a luxury honeymoon and then moving in with each other.

Each week the couples will come together for dinner parties where their relationships will be scrutinized and their progress directly compared with their fellow contestants. 

The couples will also be put under a microscope by the experts who paired them together in multiple commitment ceremonies, which will give couples the freedom to stay together or break up and leave the process. 

This will culminate in a make-or-break vow renewal, where couples will make the final decision to either recommit to their partner or separate forever. 

Commissioning Editor of Factual Entertainment, Lee McMurray, said: "I’m thrilled to be refreshing one of the portfolio’s most popular brands for E4, bringing extra scale and ambition to what is already one of the most audacious and provocative experiments on television, and delivering what we hope will be the most exciting series yet.”

Married At First Sight UK will air on E4 in 2021.
