Pretty much no such thing. Rates are set by occupation codes and/or state law. Communication linemen have a high rating. Having a history of safe practices and no claims helps with your mod rating which is a multiplier to your rate. I think ours is below 1 because we have had little to no claims in a long time. Thus since the multiplier is less than one we pay less. If you have lots of claims the rate will be multiplied to a higher rate.
Best advice is go to an insurance agent that is well versed in business insurance not just a home and auto agent. They sometimes are had to find but worth every minute spent looking for them.
