Black mould in rented property: tenant rights
Direct answer
Black mould in a rented property can engage repair, fitness, and housing-hazard duties where it affects health or is caused by defects the landlord should address. Tenants should document spread, rooms affected, health impact, reports to the landlord, and any failure to inspect or repair.
Useful evidence says where the mould is, how large it is, how quickly it returns, whether there is a leak or cold surface, and whether it affects sleeping, washing, cooking, or children's rooms.
A landlord may point to lifestyle or ventilation. Tenants should still ask for a proper investigation where there may be leaks, structural cold bridges, defective heating, extractor issues, or unfit conditions.
If the landlord does not act, contact council Environmental Health and get advice about repair, fitness, or harassment issues if the landlord responds with threats instead of action.
