The IAA (Installation Assurance Authority) is a UK-based organisation that sets standards and provides assurance for the design, installation, and maintenance of building systems. Its role is to help ensure that installations—such as electrical, fire, security, and other technical systems—are carried out safely, competently, and in line with recognised regulations and best practice.

The IAA typically operates through certification, auditing, and compliance schemes, giving clients and building owners confidence that accredited installers meet required quality and safety standards.
