Rising Utility Rates in Washington State: What Home Buyers Need to Budget For

How much will utility costs add to my monthly housing budget in Washington State?

Washington electricity rates have increased at every major utility serving King and Snohomish counties in 2025 and 2026, adding $50–$200 or more per year to the average household bill. PSE customers face a 9.6% rate hike in 2026, Seattle City Light customers 5.4%, and Snohomish PUD customers 2.5%, with all three trends expected to continue. For home buyers in Greater Seattle, utility costs are now a real budget line item that deserves attention before you close.

If you’ve been running the numbers on what you can afford in the Greater Seattle area, you’ve probably focused on the mortgage payment, property taxes, and homeowners insurance. But there’s a fourth line item that doesn’t get nearly enough attention at the purchase stage: utility costs, and right now, those costs are climbing fast across Washington state.

Every major utility serving King and Snohomish counties has approved new rate increases for 2025 and 2026. Understanding what’s happening, and how to account for it before you buy, is part of making a smart housing decision. This isn’t about political debate. It’s about your monthly budget.

What Washington Utility Rates Are Actually Doing Right Now

Puget Sound Energy (PSE), which serves much of King County’s eastern and southern areas, plus most of Snohomish County, approved a 6.9% electricity rate increase in 2025 and a 9.6% increase in 2026. For a typical residential customer using 800 kilowatt-hours per month, that’s roughly $11 more per month in 2026 alone.

Seattle City Light implemented approximately 5.4% annual increases in both 2025 and 2026, adding about $4 per month for the average residential customer. That compounds on top of prior years’ increases. Snohomish County PUD approved a 2.5% increase in 2026, adding $2–$3 per month. Tacoma Power customers will see combined 2025–2026 increases adding more than $13 per month to the average residential bill.

Depending on where you’re buying and which utility serves that property, you could be paying $50–$200 more per year than you would have two years ago, and the direction isn’t expected to reverse anytime soon.

Why Are Rates Going Up?

Washington’s Clean Energy Transformation Act (CETA) mandates that utilities eliminate coal by 2025 and achieve greenhouse gas neutrality by 2030. Meeting those targets requires heavy investment in new generation, grid upgrades, and transmission infrastructure, and those capital costs flow through to ratepayers. At the same time, aging infrastructure across the state is due for replacement, and wildfire mitigation programs are adding cost. Puget Sound Energy has published 20-year rate forecasts projecting continued increases well into the future.

What This Means When You’re Buying a Home in Greater Seattle

Industry research puts the average homeowner’s non-mortgage monthly expenses at roughly $1,974, covering utilities, maintenance, insurance, and property taxes. Utility costs are one of the few line items you can actually research before you close. If you’re working through how much house you can actually afford in King County, utility costs on a specific property can meaningfully change the answer, especially for older homes.

Ask for 12 Months of Utility Bills

Before closing, request a full year of utility statements from the seller. This gives you a real picture of what that specific home costs to heat, cool, and power, not a rough estimate. A 1970s rambler with original windows will have a very different utility profile than a 2010 townhome with a heat pump, even on the same street.

Pay Attention to the Heating Source

Natural gas rates have also increased, and electric heat is now the default in most new construction. Understanding whether a home uses gas, electric resistance baseboard heat, or a heat pump changes the math on your monthly costs. Heat pump systems are 2-3x more efficient than baseboard electric. This is one reason energy-efficient homes are commanding a real premium in Washington’s market right now.

Older Homes Have Higher Exposure

Much of the housing stock in Greater Seattle, particularly in suburbs like Shoreline, Kenmore, Bothell, Lynnwood, and south Snohomish County, was built in the 1950s through 1980s. Insulation, windows, and HVAC systems from that era weren’t designed with today’s energy costs in mind. A home with upgraded windows, added attic insulation, or a modern heat pump is worth factoring into your offer differently than a comparable unimproved home nearby.

Know Which Utility Serves the Property

Not every address in King or Snohomish County is served by the same utility. PSE, City Light, Snohomish PUD, and smaller public utility districts all serve different zones, sometimes block by block. Knowing which utility covers a property tells you what rate structure and trajectory you’re signing up for. Your agent can confirm the utility for any home you’re considering before you make an offer.

If You’re a Seller: Utility Efficiency Is a Selling Point Right Now

Buyers are increasingly cost-aware, and your home’s energy efficiency can be a genuine competitive advantage. If you’ve upgraded insulation, replaced windows, installed a heat pump, or added solar panels, those improvements have real dollar value to a buyer thinking about monthly carrying costs. Make sure your listing communicates them clearly.

Monthly utility cost estimates, when accurate and verifiable, can meaningfully differentiate your home from competing listings, especially if you’re marketing to first-time buyers stretching their budget in King or Snohomish County.

Frequently Asked Questions

How much should I budget for electricity each month in a Greater Seattle home?

A reasonable estimate for a mid-size single-family home in King or Snohomish County is $100–$200 per month, though older homes with electric baseboard heat can run $250 or more in winter months. Requesting 12 months of actual utility history from the seller is the most reliable way to budget accurately for a specific property.

Will Washington electricity rates keep going up after 2026?

The near-term trajectory is yes. The infrastructure investments required under the Clean Energy Transformation Act are still being built out, and utilities have signaled multi-year rate adjustment plans. This is one reason energy efficiency improvements in a home add durable, lasting value in this market.

Does it matter which utility serves the home I’m buying in King or Snohomish County?

Yes. Rate structures and trajectories differ by utility. PSE’s 2026 increase (9.6%) is steeper than Snohomish PUD’s (2.5%), for example. PSE, Seattle City Light, Snohomish PUD, and Tacoma Power all operate under different regulators with different approved rate schedules. Your agent can confirm the utility for any property before you make an offer.

What home features reduce electricity costs in Washington State?

Heat pump systems are the single biggest factor. They use 2-3x less electricity than electric resistance baseboard heat to produce the same warmth. After that: added attic insulation, double-pane windows, a programmable thermostat, and LED lighting. In Greater Seattle’s older housing stock, a home with all of these upgrades can have utility bills 30–50% lower than a comparable unimproved home.

Whether you’re looking at a 1960s rambler in Shoreline or a newer townhome in Bothell, knowing what you’re signing up for on utilities is part of making a decision you’ll feel good about long-term.
