Insurance Services Office Inc. Ratings

Insurance Services Office, Inc. (ISO) has completed the first countywide survey of Loudoun County's fire suppression services and has assigned new classifications, effective November 1, 2013, which could reduce residential and commercial property insurance rates, provided that properties are within five miles of a fire station.

ISO's Public Protection Classification Program plays an important role in the underwriting process at insurance companies. While use of the program is voluntary, most insurers in the United States use the information as part of their decision-making process when evaluating risk, coverage levels and pricing for personal or commercial property insurance.
