Is It Illegal to Sell a House with Damp?

Selling a house is a complex undertaking, and it’s important to ensure that all aspects of the property are in good condition. Damp issues can be a worry for both buyers and sellers, raising questions about the legal implications of selling a house with such problems. We will explore this topic to provide a clearer understanding of the potential legal considerations surrounding the sale of a house with damp issues. 

What is Dampness in a House?

Dampness refers to excess moisture or water in the structure of a building, this can then lead to other issues such as mould growth, rot and structural damage. This issue can manifest in a variety of forms, such as rising or penetrating damp and condensation. Dampness can have a negative impact on the occupants’ health and also compromise the structural integrity of the property. 

What are the Seller’s Legal Obligations?

When selling a property, sellers have specific legal obligations and responsibilities to disclose relevant information about the property’s condition. However, the specific regulations and requirements regarding damp issues can vary depending on the situation. There are key aspects to consider when selling a house with damness. 

→ Property Information Form (TA6)

The seller is usually required to complete a Property Information Form (TA6) as part of the conveyancing process. This form asks particular questions about the property’s condition, this includes any known issues with damp. It is crucial to answer these questions truthfully and accurately, ensuring all relevant information about any damp is disclosed.

→ Misrepresentation

The Consumer Protection from Unfair Trading Regulations 2008, states that sellers must avoid misrepresenting the property’s condition or concealing known damp problems. Deliberate misrepresentation or withholding of information can lead to legal issues and potential claims from buyers.

→ Duty to Inspect

 While sellers are not expected to be experts in identifying and diagnosing damp issues, they are obligated to exercise appropriate actions. If you are aware of any damp issues, you should disclose this information to potential buyers and consider allowing access for a professional inspection if appropriate.

→ Impact on Property Value and Negotiations:

Damp or rising damp problems can affect the value of a property and may impact negotiations during the sale process. The severity, extent, and underlying causes of the damp are factors that valuers and surveyors will assess when calculating the property’s worth. Buyers may factor in the cost of repairs or maintenance when considering the value of their offer.

If a buyer discovers undisclosed or misrepresented damp issues during the purchase process, they may look to renegotiate the sale price. This usually occurs to account for the necessary repairs or to address any potential concerns regarding the property’s condition.
