A heat pump's operating cost in Victoria comes down to three numbers: how much heat your home needs in a year, how efficiently the heat pump turns electricity into heat (its COP), and the BC Hydro rate you pay for the extra kilowatt-hours. Below we work through all three with sourced figures, show every step of the arithmetic, and turn it into month-by-month estimates you can compare with your own bill. These are estimates, not quotes: your house, your thermostat and your weather will move them.
What does a heat pump cost to run per month in Victoria?
For a newer 2,000 sq ft detached house, our worked example comes to about $150 in January, around $55 in October and close to nothing in July and August, for roughly $780 a year of heating electricity. A smaller townhouse lands near $390 a year; an older, leakier 2,000 sq ft house near $1,100. The table below shows all four home types.
| Home type (NRCan size assumption) | Yearly heat needed | Heat pump electricity (COP 3.0) | Yearly cost at 14.08 c/kWh | January estimate |
|---|---|---|---|---|
| Townhouse, inside unit, about 1,000 sq ft | 30 GJ (8,333 kWh) | 2,778 kWh | about $391 | about $74 |
| Newer semi-detached, about 1,500 sq ft | 45 GJ (12,500 kWh) | 4,167 kWh | about $587 | about $111 |
| Newer detached (2004 or later), about 2,000 sq ft | 60 GJ (16,667 kWh) | 5,556 kWh | about $782 | about $149 |
| Older detached (before 2004), about 2,000 sq ft | 85 GJ (23,611 kWh) | 7,870 kWh | about $1,108 | about $211 |
Space heating only. Excludes the BC Hydro basic charge (you pay it already), GST and any rate riders. If your heat pump only reaches a seasonal COP of 2.5, add 20%: the older detached house rises to about $1,330 a year and $253 in January.
How we worked out the numbers
Every figure above comes from four inputs. Here they are, with where each came from, so you can swap in your own.
1. Heat load: how much heat a Victoria home needs
Natural Resources Canada's Heating with Oil guide (revised 2012) publishes typical annual heating loads by city. For Victoria it lists 85 GJ for an older detached house (built before 2004, about 2,000 sq ft), 60 GJ for a newer detached house of the same size, 45 GJ for a newer semi-detached (about 1,500 sq ft) and 30 GJ for an inside-unit townhouse (about 1,000 sq ft). NRCan says these are general guidelines only, and real homes vary with insulation and air sealing. We convert with 1 GJ = 277.78 kWh of heat.
2. Efficiency: what COP to assume
COP (coefficient of performance) is units of heat out per unit of electricity in. A COP of 3.0 means 1 kWh of electricity delivers 3 kWh of heat. The CleanBC Better Homes Energy Savings Program requires heat pumps rated at least HSPF2 8.5 (Region IV). Dividing HSPF2 by 3.412 gives a rough seasonal COP, so 8.5 works out to about 2.5, and a unit rated HSPF2 10 to about 2.9. Region IV is a colder rating climate than Victoria's, so a well-installed variable-speed unit here should do at least as well as its label. We use 3.0 as the central case and 2.5 as the cautious case.
3. The BC Hydro rate that actually applies
BC Hydro's residential tiered rate (from April 1, 2026) is 11.87 cents per kWh for Step 1 and 14.08 cents per kWh above the Step 1 threshold of 22.1918 kWh per day, which is about 675 kWh in a 30-day month. The basic charge is 23.44 cents per day. The detail most estimates miss: your lights, fridge, hot water and cooking already use a good share of that Step 1 allowance. In a Victoria winter month, most of the extra kWh a heat pump adds lands in Step 2. So we price heat pump electricity at 14.08 cents. If your other use is low, part of it will bill at 11.87 cents and your real cost will be up to about 16% lower (the newer detached example drops from $782 to about $659 a year).
4. How the heat is spread across the year
We split the yearly heat by month using our own estimate of a typical Victoria heating season: January and December 19% each, February and November 14%, March 12%, April 8%, October 7%, May 4%, September 2%, June 1%, July and August nil. It is an assumption, not measured data, so treat the monthly figures as a shape rather than a promise.
Month-by-month heat pump running cost in Victoria
Here is the same newer 2,000 sq ft detached house across a full year, at COP 3.0 and 14.08 cents per kWh.
| Month | Share of yearly heat | Heat pump kWh | Estimated cost |
|---|---|---|---|
| January | 19% | 1,056 | $149 |
| February | 14% | 778 | $110 |
| March | 12% | 667 | $94 |
| April | 8% | 444 | $63 |
| May | 4% | 222 | $31 |
| June | 1% | 56 | $8 |
| July and August | 0% | 0 | $0 heating (cooling extra) |
| September | 2% | 111 | $16 |
| October | 7% | 389 | $55 |
| November | 14% | 778 | $110 |
| December | 19% | 1,056 | $149 |
| Year | 100% | 5,556 | about $782 |
BC Hydro bills every two months, so expect your December-January bill to carry roughly $300 of heat pump electricity in this example. Summer cooling adds to July and August; it varies too much with how you use it to put a fair number on.
Heat pump vs baseboard, gas and oil running costs
The same heat load lets you compare fuels on equal terms. This uses the newer 2,000 sq ft detached house (60 GJ of heat a year).
| Heating system | Efficiency assumed | Energy used | Price used | Yearly estimate |
|---|---|---|---|---|
| Heat pump | COP 3.0 | 5,556 kWh | 14.08 c/kWh | about $782 |
| Heat pump (cautious) | COP 2.5 | 6,667 kWh | 14.08 c/kWh | about $939 |
| Electric baseboard | 100% | 16,667 kWh | 14.08 c/kWh | about $2,347 |
| Natural gas furnace | 95% | 63.2 GJ | $12.601/GJ variable | about $796 |
| Oil furnace | 80% | 1,963 L | 256.2 c/L | about $5,030 |
Sources and assumptions: FortisBC's Vancouver Island residential rate effective July 1, 2026 totals $12.601 per GJ in variable charges, plus a basic charge of $0.4216 per day, before taxes and municipal fees. The BC carbon tax was eliminated on April 1, 2025, which is why gas runs close to a heat pump on cost alone. Oil uses NRCan's 38.2 MJ per litre and Statistics Canada's August 2026 Victoria heating oil average of 256.2 cents per litre. NRCan's guide puts new standard oil furnaces at 78-86% seasonal efficiency and old conventional burners near 60%, so an older oil system costs even more than shown.
Three takeaways. Leaving baseboard cuts the heating part of the bill by roughly two thirds at COP 3.0, which is why electrically heated homes are the ones the standard rebate targets. Leaving oil is the biggest saving by far. Against gas, running costs are close, and the case rests on cooling, removing the gas basic charge if you drop gas entirely, and rebates for income-qualified homes. Our guide to dual fuel versus all-electric heat pumps in BC works through that choice in detail.
Does time-of-day pricing lower heat pump costs?
BC Hydro's optional time-of-day add-on gives a 5 cent per kWh discount on electricity used from 11 p.m. to 7 a.m. and adds a 5 cent surcharge from 4 to 9 p.m. Heat pumps tend to work hardest on cold evenings, which is exactly the surcharge window. It can pay off only if you let the house cool in the evening and recover overnight, or pre-heat in the afternoon. Every 100 kWh you shift from the peak window to overnight saves $10. If you cannot change when you heat, it may cost you more. BC Hydro also offers a flat rate of 12.70 cents per kWh with a 25.00 cent daily basic charge, which can suit very high winter users; compare your own bills before switching.
What makes your heat pump running cost higher or lower?
- Sizing. An undersized heat pump leans on electric backup strips in cold snaps, which run at COP 1. Our heat pump sizing guide explains how load is worked out.
- Backup heat settings. Ask your installer to set backup heat to come on only below a set outdoor temperature, not every time you raise the thermostat.
- Thermostat habits. Big setbacks and quick recovery push variable-speed units into less efficient high output. Small, steady setpoints usually cost less.
- Filters and outdoor coil. A clogged filter or a coil packed with leaves cuts output. See our heat pump maintenance guide.
- The house itself. Air sealing and insulation reduce the GJ figure everything else multiplies.
What is the total cost of owning a heat pump in Victoria?
Running cost is only half the picture. Installed price depends on system type and your house; our heat pump cost guide for Victoria covers installation pricing. Then there is how you pay for it: the standard CleanBC Better Homes and BC Hydro rebate is up to $4,000 for a whole-home system or $1,500 for a partial system, for electrically heated homes only. It is one rebate from both brands, not two. Homes heated with oil, gas or propane in Greater Victoria get no standard heat pump rebate; their route is the income-qualified Energy Savings Program. BC Hydro's limited-time bonus of up to $1,000 needs installation, invoicing and payment between August 1 and October 31, 2026, with the application in by November 30, 2026, while funds last. Our guide to paying for a heat pump with rebates and financing puts the numbers together, and the rebate section on our home page summarizes them.
How to check your own heat pump operating cost
- Pull two winter BC Hydro bills from before and after your switch, or your oil or gas bills for a full season.
- Note how many kWh landed above the Step 1 threshold. That is roughly where heat pump use sits.
- Compare against the table above for your home type. If you are well above it, check filters, backup heat settings and the outdoor unit first.
- Run your own numbers in the operating cost calculator, or compare against your current fuel in the savings and payback calculator.
