What electrical repairs actually cost.

Ask three things when you call: what the service call fee is, whether diagnosis is separate from repair, and whether the service call is credited against the work if you go ahead. Electrical pricing varies more by how those three are structured than by the fault itself.

Then understand what actually drives the number, which is access.

What drives the cost

Access. The single biggest factor. A fault in an accessible basement or garage is cheap to reach. The same fault inside a finished wall, above a plastered ceiling, or under a slab means opening the building and then repairing what was opened, and the making good is often more than the electrical work.

Diagnosis time. An intermittent fault can take hours to find. A dead circuit with an obvious cause takes minutes. Nobody can quote diagnosis accurately in advance, which is why it is often charged by time.

Whether it is a repair or a replacement. Tightening a connection is a small job. Replacing a panel is a day, a permit, and usually a utility disconnection and reconnection.

Whether it triggers code work. Once a panel or a circuit is touched, current code may require additional protective devices, and in some jurisdictions touching part of a system means bringing more of it up to standard. This is the most common source of a bill that is larger than the quote.

Permits and inspection, which are required for panel work and new circuits almost everywhere.

Emergency and out of hours rates.

The common jobs, in rough order of size

• Replacing a failed outlet, switch, or light fitting. Small.
• Finding and fixing a loose connection or a dead circuit. Small to moderate, driven entirely by how long it takes to find.
• Replacing a breaker. Small in itself, and worth asking why it failed.
• Adding a dedicated circuit for a heater, an appliance, or a workshop. Moderate, and driven by the route the cable has to take.
• Replacing a panel. Substantial. A day’s work, a permit, an inspection, and a utility disconnection.
• Replacing a service, mast, or meter base, sometimes shared with the utility.
• Rewiring part or all of a house. The largest job in this category, and one that goes with plastering, decorating, and living somewhere else for part of it.

Questions that change the price honestly

Is the service call credited against the work? Some do, some do not.

Is diagnosis charged separately, and at what rate?

Is a permit needed, and is it in the number?

Will the utility need to disconnect, and who arranges it?

Who repairs the wall afterwards? Electricians typically leave the making good to you, and it is frequently a bigger job than the electrical work.

What is not in this estimate?

Where money is wasted

Replacing the breaker instead of finding the fault. A breaker that keeps tripping is usually reporting something real. What it is telling you.

Paying an electrician for what the utility does free. Anything up to and including the meter is usually theirs. Call them first. Working out which side the fault is on.

Fitting a larger breaker. Cheaper, and it is how wiring overheats inside a wall.

Doing it twice. Opening a wall for one circuit when the house needs three means opening it again.

Not asking about code. Find out at quote stage what else gets triggered.

Worth spending money on

• A whole house surge protector, at the panel. Inexpensive relative to what it protects. What surges actually do.
• AFCI and GFCI protection where an older installation lacks it. These are the devices that prevent fires and electrocutions rather than the ones that make lights work.
• Battery powered carbon monoxide alarms, which are not electrical work but belong in the same conversation. Especially if you run a generator.
• An inspection before buying a house, or on any house whose system you do not know. It is the cheapest thing in this article and the most likely to change a decision.

Insurance

Repair of the failed component is usually yours; the damage it caused is often covered. Which is which. Ask the electrician for a written statement of cause either way, because that document is what decides it.

The short version

Ask about the service call, the diagnosis charge, and whether one credits the other. Access drives the price more than the fault does. Call the utility before an electrician if the problem might be on their side. Never accept a larger breaker as a fix, and ask at quote stage what code work gets triggered.
