The emergency glazing system offered under an insurance policy is normally provided by a?

The emergency glazing system referenced in an insurance policy is typically provided by a contracted supplier. This option is correct because insurers often collaborate with specific vendors who specialize in providing glazing services in emergency situations, allowing for quick and efficient repairs to damaged glass. Using a contracted supplier helps ensure that the work is completed to a professional standard and in a timely manner, providing policyholders with necessary support after a loss.

The other roles mentioned, such as a loss adjustor or loss assessor, are involved in the claims process but do not directly provide services like glazing repairs. Loss adjustors investigate claims and assess damages, while loss assessors work on behalf of the insured to ensure a fair settlement. The specialist team employed by the insurer may also be responsible for various tasks, but they are not specifically known for providing glazing services directly like a contracted supplier would. Thus, the choice of contracted supplier is aligned with the common practices in the insurance industry concerning emergency repairs.
