Home insurance and your electrical system

Why insurers care about wiring

Electrical faults are a known cause of house fires, so insurers want to understand the wiring in a home before they cover it. For most newer homes the questions are routine. For older Edmonton homes, especially those built before the 1980s, the answers can affect whether a policy is offered and on what terms.

Every insurer sets its own underwriting rules. Two companies may treat the same house differently, and rules change over time. Your broker is the best source for how a particular insurer views your wiring. This guide explains what they are likely to ask and how an electrician can help you answer accurately.

The questions you are likely to hear

• Is there any knob-and-tube wiring? Common in homes built before about 1950. Some insurers will not cover homes with active knob-and-tube, or only after replacement.
• Is there aluminium branch wiring? Found in some homes from the late 1960s and 1970s. Insurers may ask whether connections have been remediated with approved devices.
• What kind of panel do you have? Fuse panels and some older breaker panels draw questions.
• What size is your service? Older 60 A services are a common flag.
• When was the wiring last updated, and was it permitted?

Some insurers also ask about wood stoves, home businesses, hot tubs or detached garages with power, because each adds electrical load or risk. Have the details of any of these ready.

If you do not know an answer, say so and find out. Guessing on an application can cause problems at claim time.

How an electrician can help

A licensed electrician can tell you what is actually in your walls and panel. Our home electrical inspection typically includes a look at the service and panel, a sample of circuits and devices, any visible older wiring, and a written summary you can share with your broker.

We describe what we find. We do not decide whether an insurer will cover you. Some insurers ask for specific wording or forms, so check with your broker before booking so we know what they need.

Common outcomes and upgrades

When an insurer flags wiring, the usual outcomes include:

• Coverage offered as is, once the facts are confirmed
• Coverage conditional on a repair or upgrade within a set time
• A higher premium or deductible
• Coverage declined until work is done

The matching upgrades are often whole-home rewiring to remove knob-and-tube, remediation of aluminium connections, a panel replacement or a service upgrade. Each needs an electrical permit, which itself becomes useful proof for the insurer.

Before you renew, switch or buy

A little homework makes insurance conversations much easier:

1. Find the age of the house and any renovation records you have.
2. Look at the panel label from the outside: note the brand, whether it has fuses or breakers, and the main breaker rating if it is marked. Do not remove the cover.
3. Check for permit records with your permit authority if you are unsure what previous owners did.
4. If anything is unclear, book a licensed electrician's evaluation before the renewal date or before removing conditions on a purchase.
5. Give your broker the facts and ask how their insurers treat them before you commit.

If you are buying an older home in neighbourhoods like Garneau, Highlands or Westmount, plan for these questions from the start. Mature homes are often rewired in stages over the decades, so the house you are buying may have a mix of old and new circuits.

Permits, claims and your paper trail

After a fire or electrical loss, an adjuster may look at the cause and at whether recent electrical work was permitted. Unpermitted DIY work does not automatically void coverage, but it can complicate a claim. Permitted, inspected work is far easier to stand behind.

Keep a folder, paper or digital, with permit numbers, inspection results, electrician reports and invoices. When you sell, it also helps your buyer. See electrical checks when buying or selling a home.
