E4 has announced that the finale of Married At First Sight UK will air tonight at 9pm.
The episode was due to air last night, but viewers were left disappointed when they tuned in to instead see a repeat of the previous night's penultimate episode.
The error is believed to be related to the false fire alarm at a playout centre last Saturday which disrupted the operations of many of the UK's top broadcasters.
In a tweet yesterday, the channel said: "We're aware it's yesterday's episode of #MAFSUK playing out this evening and apologise. It's all down to our ongoing tech issues which we're working hard on."
The final episode will now air tonight at 9pm, with discussion show Afters following at 10pm.
