Can the council stop my landlord from letting out my flat if it has damp and mould?

Based on the inspection by the Manchester environmental health team, the council can take action if they find the damp and mould constitute a hazard. Under the Housing Act 2004, the council can issue what is called a 'prohibition order'—a legal command that stops a property from being used in a certain way to protect people [cite:uk-housing-act-2004-sec21]. If the council determines the mould is a 'category 2 hazard', they "may make a prohibition order under this section in respect of the hazard" [cite:uk-housing-act-2004-sec21]. This means they have the discretion to step in and forbid the use of the premises to ensure safety. If the hazard is even more severe and classified as a 'category 1 hazard', the council has a duty to consider making such an order [cite:uk-housing-act-2004-sec20]. Regarding your specific flat, if the council issues a prohibition order, it could specifically target the use of your two-bedroom flat. For flats, the order "may prohibit use of the building containing the flat or flats (or any part of the building)" [cite:uk-housing-act-2004-sec20]. This means Mr. Thompson could be legally barred from letting the flat to anyone else until the ventilation and mould issues are resolved. The law does not explicitly state whether the council will choose to fine him or issue a prohibition order; rather, it provides them with different tools depending on how dangerous the hazard is. Whether they choose to issue an order or simply fine him depends on the specific category of hazard they assign to the mould during their formal assessment.
