Protecting your home’s electrical system is well worth the cost of whole-house surge protector installation. On average, a whole-house surge protector costs about $500, including labor and materials, ranging from $200 to $800. This device shields your electronics and appliances from dangerous voltage spikes, including internal and external power surges.
A whole-house surge protector connects directly to your main electrical panel, intercepting and redirecting excess electricity before it can damage your electronics. The final cost of a whole-home surge protector varies based on the surge protector type, brand, labor costs, and any potential additional electrical system repairs or upgrades your home needs.
Average Cost | High Cost | Low Cost |
---|---|---|
$500 | $800 | $200 |
The two main whole home surge protector cost factors that determine your total price are the cost of buying the surge protector unit and hiring a licensed electrician to install it. Additional factors that may contribute to your final cost include electrical upgrades and building permits.
Depending on brand, capacity, and other factors, a whole-house surge protector costs $60 to $500 for the unit itself. Whole-home surge protectors come in three types:
Type 1 surge protectors are installed before the main circuit breaker box and offer the greatest protection.
Type 2 surge protectors are installed on a single electrical circuit or the breaker box, protecting against internal surges.
Type 3 surge protectors are power strips that only protect devices plugged into a single outlet.
The surge protection rating describes the unit’s surge capacity. Ratings range from 10 kiloamperes (kA) to over 100 kA. Most homeowners should opt for a unit rated for at least 30 kA or more to protect against lightning strikes. In addition to the surge protector unit, you may also need to pay for a grounding mechanism and voltage regulation system.
Surge Protector Type | Cost Range (Materials) | Cost Range (With Installation) |
---|---|---|
Type 1 | $100–$500 | $250–$800 |
Type 2 | $60–$300 | $200–$450 |
Type 3 | $10–$60 | $10–$60 |
Type 1 whole-house surge protectors cost $100 to $500 for the unit itself. They cost the most because they offer the highest level of surge protection. All the power that enters a home flows through this type of surge protector, mitigating potential damage from external surges like lightning storms. A professional electrician installs a type 1 protector on the line side of the main electrical panel before the main circuit breaker box.
Type 2 whole-home surge protectors cost between $60 and $300 for the unit itself. They are the most popular type of surge protection device, often installed on a single circuit. This type of device protects primarily against internal surges, though it can also protect against some external surges. Type 2 whole-house surge protector installation costs about the same as a type 1 device when installed on the home’s main electrical breaker box.
Type 3 surge protectors offer the least amount of protection but also cost the least, at $10 to $60 each. You most commonly find these units at your local hardware or electronics store as a power strip that you plug into a single wall outlet. They offer limited protection for electronic devices you plug directly into them, but they do not require professional installation.
Generally, the electrical systems in larger homes are more powerful and complex. As a result, they often require more extensive surge protection. If your home has subpanels, you may need to invest in additional surge protectors for each electrical panel, which can further increase your total cost.
In some cases, before you can install a whole-home surge protector, you may need to first install an upgraded electrical panel. Electrical panels can last 25 to 40 years, but older panels may be faulty and need to be replaced.
The cost of your electrical panel upgrade depends first on the panel’s capacity. A smaller 100-amp panel may cost $500 to $1,500 to install, while a more powerful 200-amp panel costs $750 to $2,000. With modern appliances and electronics demanding more power, upgrading to a higher amperage may be worth the extra investment.
Electrical Panel (Amps) | Cost Range |
---|---|
100 | $500–$1,500 |
150 | $500–$1,750 |
200 | $750–$2,000 |
400 | $1,500–$4,000 |
Labor can account for about half of your whole-house surge protector installation costs. Typical electrician rates range from $50 to $100 per hour. In most cases, installing a whole-home surge protector is a reasonably straightforward job that shouldn’t take a qualified electrician more than a couple of hours to complete.
Expect to pay around $150 to $200 for labor alone, as many electricians charge a minimum service call fee. They may also quote flat-rate pricing for the project. Bundling multiple electrical projects can reduce overall costs.
It’s vital to hire a professional electrician for the job because you may invalidate the warranty if you try to install it yourself. It may also invalidate your homeowner’s insurance for claims involving damaged appliances and electronics.
Before installing a whole-house surge protector, you may want to replace your home’s electrical panel and consider other repairs and upgrades:
Electrical repairs cost anywhere from $100–$4,000 or more, depending on what is needed.
Uninterruptible power supply system installation costs an average of $15,000 to protect your whole home.
Rewiring a house costs $600–$2,600, depending on the size of the home and the type of electrical wiring.
Installing a new electrical outlet costs $140–$320, more if you need a GFCI-protected or 220-volt outlet.
Ask local electricians to evaluate your home’s current wiring and electrical system to uncover potential issues and identify where and what you may want to upgrade.
Some areas may have specific legal requirements for residential electrical work, like whole-home surge protector installations. An electrical inspection costs $100 to $400, while required building permits cost $50 to $200, on average. Check with local building codes and regulatory bodies, or ask your professional electrician to do this for you.
Installing whole-house surge protection can incrementally increase your home value by demonstrating to prospective buyers that you take proactive steps in electrical system maintenance. It’s a sound investment in home safety.
While not a major value-adding renovation, whole-home surge protection installation can prevent damage to expensive electronics and appliances, potentially reduce home insurance premiums, and serve as a positive signal to home inspectors and possible buyers.
Protecting your house’s electrical system can be an affordable home upgrade. Smart budgeting helps you manage installation costs while ensuring adequate protection against power surges:
Get at least three quotes from licensed electricians to compare prices.
Discuss the type, brand, and surge capacity with your electrician to determine the best solution for your home.
Bundle the surge protector installation with other electrical system upgrades.
Check your home insurance policy for potential discounts.
Look for potential manufacturer rebates and carefully review warranties.

You should install a whole-house surge protector to protect your home’s electrical system and all connected devices from voltage spikes caused by lightning, power grid fluctuations, and internal appliance issues. The surge protector intercepts excess electricity at the main panel, preventing damage to electronics and your home’s HVAC system and extending the lifespan of your appliances. It is especially important in areas prone to thunderstorms or in houses with older electrical systems.
Whole-house surge protectors last two to three years. Even if you never experience a high-level power surge, your home will likely experience many low-level surges that eventually wear out the surge protector. These surges are so small that you may never even notice them aside from during full power outages. Still, they take an accumulated toll on your home’s electronics, appliances, and HVAC equipment.
A surge protector works as soon as it's properly installed, protecting any electrical device or appliance connected from power surges, however big or small. This includes protecting your AC unit and any other HVAC equipment in your home. Whole-house surge protectors work against lightning strikes and surges from other appliances and the electrical grid, diverting excess current away from your electrical system and safely into the ground.
A whole-house surge protector is installed on your property's electrical panel. It then detects surges in current, however small, and diverts the excess away before it reaches your home's electrical circuit. The excess is harmlessly diverted into the ground, where it dissipates, and the remainder travels safely into your home to continue powering your electronics.
