What Is A Certificate Of Structural Adequacy?

Reading time: 1 min

A certificate of structural adequacy (CSA) is a document issued following the completion of remedial works for subsidence. 

The certificate will include,

  • Terms of Appointment, 
  • Description of damage to the property, 
  • Cause of damage to the property, 
  • Mitigation measures, 
  • Description of the works completed. 

 

A Chartered or Structural Engineer signs off the work, and this confirms that the works have been completed exercising reasonable skill, care, and diligence.

Why is it important?

A certificate of structural adequacy can improve your chances of obtaining home insurance, including subsidence cover and a mortgage. Mortgage Providers are likely to refuse a property where there is an active subsidence issue, so the document is useful where you are looking to buy or sell a property with a history of subsidence.

 

Is there anything else I should know?

Yes. Many homeowners worry that subsidence will devalue their property, but having a certificate of structural adequacy can help retain the value of a property. It shows that the subsidence problem has been dealt with.
