How Much Does It Cost to Install a Generator Transfer Switch in Boston, MA? [2026 Data]

Generator transfer switch installation in Boston, MA, costs between $1,300 and $1,733, with an average price of $1,570. Your total cost depends on the size and type of transfer switch, the number of circuits you want to power, and the complexity of connecting it to your home's electrical system.

Boston's nor'easters, severe thunderstorms, and occasional power outages prompt many homeowners to install transfer switches for whole-house generators or portable generators to keep essential systems running during emergencies. This guide explains installation costs and the factors that affect pricing.

Generator Transfer Switch Installation Cost Factors

Electrical power outages happen in and around Boston, MA. Knowing how to use a generator and choosing a model and an appropriate transfer switch to fit your needs and budget helps to create a sense of security.

The size and type of the switch you need are the primary cost factors. However, additional considerations, such as your home's electrical configuration, can also affect pricing.

Size of Generator Transfer Switch

Depending on the size of your generator, you’ll need a transfer switch of the same capacity and ampacity to keep your Boston, MA, home running during an emergency. Here’s how the cost is impacted by generator size in watts:

Type of Generator Transfer Switch

An automatic generator switch is more expensive than a manual switch. Here’s how the two compare:

Amp Requirements

As the amp requirement increases, the cost of the generator transfer switch will also rise. That’s because higher-amperage switches use stronger parts and better materials to safely handle the extra electricity, which makes them more expensive to manufacture.

Number of Circuits

Multi-circuit transfer switches get more expensive as the number of circuits increases. That’s because more circuits mean more hardware and wiring inside the box, and they can also make installation more labor-intensive. For example, a six-circuit switch might start around $215, while a 16-circuit unit often costs $1,085 or more.

Existing Electrical

To ensure your electrical panel is up to code, your electrician may need to upgrade your electrical panel or subpanel, or install new circuit breakers, before installing a generator transfer switch. Here’s what you might pay for each task:

Permits

The average cost for a generator transfer switch permit is between $55 and $380. While obtaining a permit for a portable generator isn’t usually necessary, installing a whole-home generator requires a permit for electrical upgrades.

Generator Transfer Switch Installation Pro Costs

Hiring a Boston, MA, generator pro costs between $55 and $110 per hour, regardless of the type of generator. The time needed to complete the work will depend on the amount of electrical work required.

While it's technically possible to install a generator transfer switch as a DIY project, the task requires specialized training and direct work with the home's electrical system. Significant property damage, personal injury, and other serious problems can result from a DIY error.

Most homeowners simply keep themselves and their families safe and ensure the transfer switch's reliability and code-compliance by hiring a pro to handle the job.

Does Installing a Generator Transfer Switch Increase Home Value?

Many Boston, MA, residents find that installing a whole-house generator is worth it simply for protection against the unpredictable weather. The installation will also include the cost of the transfer switch. However, another consideration for putting one in is that completing the project can add value to the property.

Area homeowners often realize a 3% to 5% increase in home value after completion, which is significantly higher than national averages for the same project. Additionally, they often recover between 50% and 150% of the project's cost in resale value. However, it's important to note that the installation must be properly permitted and of professional-level quality to be of any value.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
