Questions Buyers Should Ask About Utility Costs

Before you fall in love with a home, it's worth asking a question that often gets overlooked: What does it actually cost to live here? The purchase price is just the beginning. Monthly utility bills can vary significantly from one property to the next, and they can have a real impact on how comfortable that new mortgage feels 12 months in.

What Are the Average Monthly Bills?

Start by asking the seller or their agent for 12 months of utility statements. One month doesn't tell you much. A July electricity bill looks very different from a January heating bill, and what you want is the full year: highs, lows, and averages. This gives you a realistic picture of what you're committing to.

If the seller can't provide that history, contact the utility providers directly. Many will share average usage data for a specific address.

How Old Are the Major Systems?

The age and condition of the furnace or heat pump, water heater, and insulation directly affect what you'll pay each month. An aging furnace can cost noticeably more to operate than a newer, high-efficiency model. Ask when key systems were last replaced and whether any energy-efficiency upgrades have been made. A home with updated insulation, newer windows, and a modern heating system will typically run more efficiently than one that hasn't been updated in several years.

Is the Home Well-Insulated?

Poor insulation is one of the most common reasons utility bills run high. Ask whether the attic, walls, and basement have been insulated, and to what standard. In much of Canada, freeze-thaw cycles and prolonged cold seasons make insulation quality especially important; a poorly sealed envelope can mean a furnace working overtime from November through March. You might also ask whether the seller has had an energy audit. If not, you can request one as part of your conditions; it's a relatively low-cost way to identify where heat is escaping and where future savings might be found.

What's the Water Situation?

Water costs tend to fly under the radar, but they can add up. Find out whether the home is connected to municipal water and sewer or uses a private well and septic system. Each comes with different ongoing costs.

A private well may mean there is no municipal water bill, but buyers should budget for testing, treatment systems, pump maintenance, and potential repairs. A septic system may also require regular inspections and pump-outs. Municipal water and sewer costs are more predictable, but bills can vary based on usage, fixed service fees, and local rates.

Are There Any Known Efficiency Issues?

It's a simple question, and sellers sometimes have useful answers. Have there been issues with drafts or rooms that never seem to warm up? Are there appliances that run constantly? Even small issues, such as a leaky water heater, an old refrigerator, or poor duct sealing, can add meaningfully to monthly costs. In provinces with tiered electricity pricing, hydro pricing, or time-of-use rates, inefficient systems can cost more than you'd expect.

Why This Matters

Understanding utility costs before you buy helps you budget accurately, negotiate more confidently, and avoid unwelcome surprises after closing. The home might check every box on your list. Make sure the monthly carrying costs do too.
