Making an existing home more energy-efficient in BC: the evaluation, staged upgrades, and the rebates open in October 2026

Start with an EnerGuide home evaluation

Natural Resources Canada describes the EnerGuide home evaluation as an assessment from basement to attic by a registered energy advisor. The advisor measures airtightness with a blower door test and records the insulation levels of walls, ceilings and basement, the number, type and location of windows and doors, and the size and efficiency of the heating, cooling, water heating and ventilation equipment. That data goes into energy software that calculates the home's EnerGuide rating.

The home has to be ready. Natural Resources Canada lists the conditions: clear access to attics, crawl spaces and equipment; a heating system that can hold 22°C; all windows and doors in place (one may be missing if it is covered and sealed); and an intact shell. Any renovation underway may affect only interior partitions. If a temporary seal fails during the blower door test, the home cannot be evaluated that day.

After the visit, the owner receives an EnerGuide rating and label, a Homeowner Information Sheet and a Renovation Upgrade Report. The report lists recommended upgrades with their expected energy results, shows heat loss by building part before and after, and gives the rating before and after the recommended work. Some programs have also required a second evaluation after the work; the Canada Greener Homes Loan, now closed, paid its balance only after a post-retrofit evaluation confirmed the work.

Doing the work in stages

Upgrades can be spread over several years. The order matters, because each step changes what the next one needs. The upgrade report's heat loss chart shows which parts of the house lose the most heat. Sealing air leaks and adding insulation first lowers the heating load, so heating equipment chosen afterward can be sized to the smaller load under CSA F280.

The Passive House Institute has a retrofit standard, EnerPHit, for existing buildings rebuilt with Passive House components. Its criteria allow an airtightness result of 1.0 air changes per hour at 50 pascals. The Institute's page describes a step-by-step route with an EnerPHit Retrofit Plan, which maps every stage to the finished state, and offers pre-certification once the first step is done and has saved at least 20 percent of energy.

A large renovation may bring in the building code. The City of North Vancouver's page says renovations to residential buildings must show compliance with Section 9.36 of the BC Building Code, at Step 3 where every mechanical system counts as a low carbon energy system and at Step 5 where it does not. Other cities treat renovations their own way, so ask the building department what your scope triggers before you price the work.

If the house may be replaced by a multiplex in the next few years, weigh each upgrade against how long the house will stand. A feasibility review of the lot answers that question before you spend on either path.

Rebates and programs listed as open on 24 October 2026

The table below lists programs as their owners' pages showed them on 24 October 2026. Better Homes splits its rebates into ground-oriented homes and multi-unit residential buildings; the table covers the first group. Programs open and close often. The Better Homes BC site also showed a notice that day saying it is not being updated during a provincial election period, so confirm each amount with an energy coach before you sign a contract.

The CleanBC Home Renovation Rebate is open to households at any income level. Its page says the home must be a year-round primary residence at least 12 months old, a household member must hold a residential account with BC Hydro, FortisBC or a municipal utility, most rebates need a program-registered contractor, and you apply within 6 months of the work. Heat pump rebates for homes heated with oil, gas or propane are listed only in the northern section, for homes at or north of 100 Mile House.

The Energy Savings Program is for lower-income households. Eligibility depends on the number of people in the home, their combined pre-tax income and the home's assessed value. The contractor receives the rebate and you pay the rest. Its top level, level 3, is only for ground-oriented homes switching from natural gas, propane or oil space heating to an electric heat pump.

BC Hydro's own heat pump rebate requires the heat pump to replace a primary all-electric heating system, such as baseboards or an electric furnace, to have a variable-speed compressor, to be on BC Hydro's rebate-eligible list, and to be installed by a member of its Home Performance Contractor Network. Federal support has narrowed: Natural Resources Canada lists the Canada Greener Homes Loan as closed because its funding is fully committed, and the Canada Greener Homes Affordability Program, which offers no-cost retrofits to low-to-median-income households, is delivered in BC through BC Hydro and FortisBC.
