When you’re faced with frequent power outages or planning for long-term resilience, one question often comes up: How much does it cost to install a generator? While it might seem like a straightforward inquiry, the cost can vary significantly depending on a wide range of factors. These include the size and type of generator you choose, your property’s layout, required permits, transfer switch installation, and even site preparation. It’s not a one-size-fits-all solution.
The average price to install a standby or whole-house generator ranges between $6,000 and $11,000, including both the generator and professional installation. Smaller systems or portable generators may cost as little as $1,500 to $3,000, while complex, high-capacity systems can exceed $15,000. Labor typically makes up 30% to 50% of the total installation cost, especially if the project requires trenching, fuel line installation, or upgrades to the electrical panel.
Additional components such as concrete pads, surge protectors, and cold-weather kits also contribute to the final cost. Local building codes may require permits and inspections, adding anywhere from $50 to $450. If you’re installing a fuel-powered system (like natural gas or propane), you’ll also need to account for plumbing costs and possibly utility coordination.
In short, installing a generator is an investment, but one that offers peace of mind, uninterrupted functionality, and, for businesses, protection from costly downtime. For an in-depth cost analysis, refer to The Spruce’s guide on whole-house generator costs.
Cost Factor 1: Generator Unit Price
The generator itself is one of the largest components of your total installation cost. Depending on your power needs, generator unit prices can range from a few hundred to tens of thousands of dollars. If you’re simply looking to power a few essential appliances, a portable generator with a power rating of 1,000 to 5,000 watts may be all you need and these typically cost between $500 and $2,500. However, portable units are not usually wired directly into your home’s electrical panel and require manual setup during outages.
On the other hand, standby generators, which can automatically switch on during a power outage, offer more convenience and broader coverage. These systems start at around $3,000 for basic models and can go up to $15,000 or more for premium brands with extended capacity and smart features. For example, a 22kW Generac generator, suitable for powering a whole medium-sized home, costs about $5,000 to $6,500 before installation.
If you run a large household or operate a business with critical equipment, investing in a 48kW or industrial-grade generator may be necessary. These systems can easily exceed $18,000, excluding accessories and installation.
Ultimately, the generator model you choose should match your home’s or business’s energy needs.

Cost Factor 2: Labor & Installation
Labor costs are often underestimated but make up a significant portion of the total price when installing a generator. For residential systems, installation typically costs between $3,000 and $5,000, depending on the complexity of the job. If trenching is required to run conduit or gas lines, or if you’re installing on difficult terrain, expect the price to climb higher. Urban installations may also require permits, scheduling with city inspectors, and coordination with utility companies, all of which extend timelines and add costs.
Moreover, installing a generator involves more than just placing it on a slab and plugging it in. It includes:
- Installing a transfer switch.
- Running and connecting electrical wiring.
- Hooking up fuel lines (natural gas, propane, or diesel).
- Ensuring grounding and ventilation.
- Completing necessary inspections and compliance with codes.
If you’re switching from a gas to an electric water heater or upgrading your panel, additional licensed work may be required. Commercial properties may face even steeper costs due to their power needs and strict code requirements.
At Expert Electric, we specialize in complete generator installations that are not only code-compliant but also optimized for safety and performance. Our electricians ensure the job is done efficiently, giving you a reliable source of backup power for years to come.
Cost Factor 3: Transfer Switch & Site Preparation
One of the most overlooked components of a generator installation is the transfer switch. This device allows your generator to safely supply power to your home or business during an outage without backfeeding into the grid. A manual transfer switch may cost $500–$1,000, while an automatic transfer switch (ATS) can run from $1,500 to $2,500, depending on the amperage and brand.
An ATS is ideal for homeowners who want the generator to turn on automatically when the power goes out, no hassle, no running outside in the rain or snow. For businesses, this is practically a requirement to maintain operational continuity.
In addition to the switch, site preparation can affect overall installation costs. Generators are typically installed on a concrete or gravel pad, which must be level, weather-resistant, and meet local codes. Installing a concrete pad may cost $800 to $1,200, depending on size and site accessibility.
If the generator must be placed far from the main panel or fuel source, trenching may be necessary to run electrical conduit and gas lines. This can add several hundred to thousands to the total job cost.
Bottom line: ignoring these essential but “invisible” costs can lead to sticker shock. A thorough site evaluation by Expert Electric can help prevent surprises and streamline your project planning.
Cost Factor 4: Permits, Fuel, and Ongoing Maintenance
Depending on your city or municipality, installing a standby generator may require electrical, plumbing, and/or building permits, which can cost between $50 and $450. Some areas may also require environmental assessments if fuel storage tanks are involved. Failing to get proper permits can result in steep fines or being forced to remove the installation altogether.
Your generator’s fuel type (natural gas, propane, or diesel) significantly affects the total cost as well. Connecting a generator to a natural gas line requires plumbing by a licensed technician, often adding $500 to $2,000. Propane systems need above- or underground tanks and regular refueling. Diesel units, though robust, demand strict maintenance to avoid fuel contamination.
Long-term, you’ll also need to budget for maintenance, which includes oil changes, filter replacements, battery checks, and software updates. On average, generator maintenance costs $150 to $300 annually, depending on use. This ensures your system is reliable and ready to perform during emergencies.
By working with Expert Electric, you get access to generator professionals who not only handle installation and permits but also offer ongoing maintenance packages to keep your investment in top shape.

What is the average cost to install a generator?
The average cost to install a generator in Canada ranges from $6,000 to $11,000, but costs can reach $15,000+ for high-capacity systems or installations with complex requirements. These prices include the generator unit, professional installation, permits, and site prep. Portable generators can be installed for less, around $1,500 to $3,500, but they typically don’t provide whole-home coverage or automatic operation.
What influences the cost the most?
The main cost drivers include:
- Generator size and type (portable vs. standby).
- Fuel source (natural gas, diesel, or propane).
- Labor required based on the difficulty of installation.
- Transfer switch type and amperage.
- Location of the generator in relation to electrical and gas hookups.
- Permit and inspection fees.
A professional assessment from Expert Electric helps identify these variables early.
