The overnight closure is due to reduced flight operations. Though I know Ryanair would operate more flights if the terminal was open all night but that’s my opinion. Also it gives MAG the benefit of having minimal staff numbers in so meaning they can furlough a majority of the workforce and save money for the meantime.
MAG have had a ban on all new construction work at Stansted since around May last year any project that continued where ones that where already payed for. Such as the new HBS (Hold Baggage System) which has just been completed 2 months ahead of schedule.
The overnight closure began around end of March/early April last year can’t remember exact dates. But the terminal has reopened over night since then but during each lockdown MAG made the decision to close overnight each time.
