What carriers are asking about
There is no statewide rule here, and anyone who tells you there is should be treated carefully. Underwriting guidelines vary by carrier and change frequently. What has been widely reported in California is a tightening around older systems: knob-and-tube wiring, aluminum branch wiring, fuse panels, 60-amp services, and specific panel brands including Federal Pacific and Zinsco. Reporting in 2024 covered at least one major carrier declining new policies on pre-1976 homes with knob-and-tube or aluminum wiring, and brokers describing applications being declined once those systems are disclosed. Your own carrier's position is the only one that matters, and it is worth asking them in writing.
The documentation matters as much as the work
Carriers rarely want a description — they want evidence. In practice that means the permit number, the final inspection sign-off from the authority having jurisdiction, dated photographs of the finished work, and an invoice from a licensed contractor with the license number on it. We provide all of that as standard, because it is the part that actually closes the file. Work done without a permit, however well executed, is very hard to evidence to an underwriter, which is one more reason we do not skip them.
Plan around the written requirements
If an insurer has raised an electrical concern, obtain its requirements and deadline in writing. We assess the proposed electrical work and discuss the documentation that can be provided. The insurer makes its own underwriting decisions, and the project should not be sold as a guaranteed renewal or approval.
Common questions
My insurer says I have to replace my panel. Do I?
If they have made it a condition of cover, that is between you and them — we cannot overrule an underwriting decision. What we can do is tell you honestly what your panel's actual condition is, do the work properly if it is needed, and give you the documentation to close it out. If we think the panel is sound we will say so, which occasionally helps in a conversation with a broker.
What paperwork will they want?
Usually the permit number, the final inspection sign-off, an invoice from a licensed contractor showing the license number, and photographs. We provide all of it. Ask your agent in writing exactly what they need before the work starts, and we will make sure what we hand you matches the list.
Will upgrading actually lower my premium?
We cannot promise that, and we would be suspicious of anyone who does — pricing is the carrier's decision and depends on far more than the electrical system. What it more realistically does is remove a reason to decline or non-renew, and widen the set of carriers willing to quote you at all.
Technical planning notes & references
BEFORE WE QUOTE THE WORK
Start with the insurer’s actual request
Get the requirement in writing
Panel identity, wiring type, repairs, photographs and contractor statements are different scopes. Share the written request and deadline so the proposal addresses the question instead of assuming full replacement is necessary.
Separate work from underwriting
Completed work and permit information can be documented where applicable. Coverage remains the insurer’s decision. A replacement should not be represented as a guarantee of renewal or approval.
