Black mould in rental properties is about to become a very serious issue for landlords.
Under the Renters Rights Act the rules around property condition are tightening significantly.
Here is what every landlord needs to know.
Black mould is no longer something you can ignore or blame on the tenant.
The Decent Homes Standard is being extended to the private rented sector for the first time. This means your property must be free from serious health hazards. Black mould caused by structural issues, poor ventilation or inadequate heating is a landlord responsibility — not a tenant lifestyle choice.
If a tenant reports black mould and you fail to act, they will have the right to complain to a new Private Rented Sector Landlord Ombudsman. That body will have the power to force repairs and award compensation.
Local councils are also getting stronger enforcement powers. Fines for non-compliant landlords are increasing significantly.
The bottom line is this.
If you have black mould in any of your rental properties — fix it now. Before the Act comes into force on 1st May. Before a complaint is made. Before a fine lands on your doorstep.
Good landlords have nothing to fear from this.
Bad landlords do.
