Nova Scotia Home Energy Rebates 2026: What Stacks, What Closed, and Two Worked Examples

Nova Scotia Home Energy Rebates 2026: What Stacks, What Closed, and Two Worked Examples

The Short Answer

In November 2026 a Nova Scotia homeowner can draw on up to $5,000 in Efficiency Nova Scotia Home Energy Assessment rebates, up to $5,000 more from the Moderate Income Rebate if the home is heated mainly by a non-electric fuel and the household qualifies, and the federal National Heat Pump Rebate of $2,000, or up to $10,000 for households at or below the Nova Scotia income limit. Low-income owners can get insulation, air sealing and heat pumps installed free through HomeWarming. The federal Oil to Heat Pump Affordability program and the Canada Greener Homes Loan no longer take new applicants. Every figure here was checked against the program's own documents on November 13, 2026.

The order matters more than the amounts. The provincial rebates only pay for work done after an initial assessment, while the federal rebate pays for heat pumps installed from November 1, 2026 even though its portal will not open until early 2027. Get the sequence wrong and a homeowner can lose the provincial share entirely.

Who Runs What in Nova Scotia

Three layers of money reach a Nova Scotia house, and they come from different places.

Efficiency Nova Scotia is the province's efficiency utility, operated by EfficiencyOne. It runs the Home Energy Assessment program (HEA), the Moderate Income Rebate (MIR), HomeWarming, and the instant rebates on products sold at retailers. Its programs are funded partly through Nova Scotia Power bills: the power company's own rate page says the energy charge includes a Demand Side Management rider that pays for efficiency programs. In other words, every customer already pays for these rebates, which is a fair reason to use them.

The federal government now runs one heat pump program for owners at all income levels, the National Heat Pump Rebate, delivered by Environment and Climate Change Canada. It also sends money through the province: a June 29, 2026 provincial release put $20 million from the Canada Greener Homes Affordability Program, plus $6 million provincial, into HomeWarming and the African Nova Scotian Communities Retrofit Program, adding room for more than 1,600 households.

Municipalities offer financing, not grants. Halifax's HalifACT Home Energy Upgrade program lends at a fixed 4.75% over 10 years, repaid as an annual charge billed separately from the property tax bill. Several other municipalities run their own versions, so ask your town hall before assuming nothing exists.

Nova Scotia Power is the fourth player, even though it pays no rebate here. Its rate sets the running cost of every heat pump in the province, and on May 1, 2026 that rate rose to 19.128 cents per kWh, with a basic charge of $20.08 a month.

The Stacking Table

This is the table to keep. It lists each program open or recently closed to a Nova Scotia homeowner, the amount, who runs it, whether you need approval before work starts, and what it combines with. Amounts were checked on November 13, 2026.

Three rules sit behind that table.

1. One upgrade, one Efficiency Nova Scotia program. The June 2026 rebate guide says a single upgrade cannot be claimed under more than one Efficiency Nova Scotia program unless stated otherwise. HEA and MIR are the stated exception for exterior wall and basement wall insulation, where the MIR rebate adds to the HEA one. HomeWarming is not an exception, because free work is already fully paid.
2. Rebates never exceed cost. HEA rebates are capped at 100% of what the participant actually spent. That cap starts to bite when HEA, MIR and the federal rebate are all applied to one modest install, as the first worked example shows.
3. The federal rebate is one per address. The NHPR page requires that federal funding has not previously been provided for a heat pump at the address. A home that already used OHPA or the old Canada Greener Homes Grant for a heat pump should expect to be ineligible.

Efficiency Nova Scotia's Home Energy Assessment, Measure by Measure

The HEA program is the backbone. A Registered Energy Advisor visits, tests the house and writes a report. You do the recommended work, the advisor comes back for a final assessment, and Efficiency Nova Scotia mails a cheque, generally within 90 days of that final visit. The initial assessment costs $199. It is free for low- to moderate-income households. All upgrades and the final assessment must be finished within 12 months of the first visit; your advisor can request an extension, but the guide warns that rebate terms may change in the meantime.

The rebate amounts below come from the June 2026 edition of the HEA rebate guide. Insulation rebates rise with the share of the area you insulate, which is why each line shows a range: the low end is the minimum 20% of the area, the high end is all of it.

Four details in that guide change real decisions.

Heat pump rebates are paid on added capacity. One ton is 12,000 BTU per hour. A replacement heat pump is not eligible under HEA. If you already have a 1-ton ductless unit and replace it with a 1-ton unit, the HEA heat pump line is zero. If you add a second head of 1.5 tons, that 1.5 tons is what counts.

Row homes get less. Semi-detached and end units receive 75% of the maximum for foundation and exterior walls; middle units get 50%. Shared walls are not eligible at all.

Product instant rebates do not double up. A heat pump water heater that already received an Efficiency Nova Scotia instant rebate at the store is not eligible for the $800 HEA amount.

Keep the paperwork for five years. The guide asks participants to keep invoices and receipts for that long. Our audit and rebate documentation checklist lists what each kind of invoice should show.

The HEA ceiling is $5,000. Most houses reach it only with a large insulation job plus a heat pump. A 3-ton ducted heat pump earns $1,500; a full attic from R-12 earns $750; a full basement wall to R-22 earns $1,200; air sealing earns $200. That combination is $3,650, still under the ceiling. The full program page is summarized on our Efficiency Nova Scotia Home Energy Assessment program record.

The Moderate Income Rebate

The MIR adds up to $5,000 on top of HEA, for a combined $10,000. It has three conditions that rule many people out:

1. Pre-approval is required before work starts.
2. You must own the home and live in it as your primary residence.
3. The home must be heated primarily by a non-electric source. Electrically heated homes are not eligible.

For those who qualify, the MIR amounts are large on heat pumps. A ductless heat pump earns $500 per ton and a centrally ducted heat pump earns $1,500 per ton. Whether those heat pump amounts add to the HEA heat pump rebate or replace it is not spelled out in the guide's stacking note, which names only the wall and basement rebates as combinable; ask your energy advisor at pre-approval. Wall insulation does get a second rebate: adding R-7.5 or more to above-ground walls earns $200 to $1,000 under MIR, and basement walls to R-22 or more earn $150 to $750. The income limits for MIR are set by Efficiency Nova Scotia and are checked at pre-approval; the program page renders only in a browser, so confirm the current limit for your household size there or by phone before you book.

The practical effect: an oil-heated house of a moderate-income family gets at least $1,500 per ton for a ducted heat pump from the province, and $2,000 per ton if the HEA amount also applies, against $500 per ton for an above-limit household.

HomeWarming: Free Upgrades for Low-Income Owners

HomeWarming does not rebate. It installs. Efficiency Nova Scotia's application form, March 2025 edition (the latest posted when we checked), sets these annual household net income limits:

Net income is line 236 minus line 435 on your Notice of Assessment, which is income after tax. You must own and live year-round in a single-unit home such as a detached house, semi, townhouse or mobile home. Condos, multi-unit buildings and rentals do not qualify, and homes that already received HomeWarming upgrades are generally not eligible again. The form notes that oil-heated homes using more than 500 litres a year may qualify for a heat pump and any electrical panel work it needs.

The June 29, 2026 funding increase matters for timing. The province said $26 million would let more than 1,600 additional households in, with insulation, air sealing and heat pumps installed at no cost. If your income is anywhere near the limit, apply to HomeWarming before paying $199 for a standard assessment: one program pays for everything, the other pays part.

The federal Canada Greener Homes Affordability Program money reaches Nova Scotia through HomeWarming, not through a separate federal application. Our CGHAP application guide covers how the program works in each province.

The Federal National Heat Pump Rebate in Nova Scotia

The federal government announced the National Heat Pump Rebate on October 8, 2026. The Canada.ca program page, modified November 5, 2026 and read for this guide on November 13, sets these rules:

• Amount. $2,000 for households above the median income. Up to $10,000 for households at or below it, with the actual amount depending on income and equipment cost.
• Timing. The online portal is expected to open in early 2027 and to close in March 2034. Heat pumps installed from November 1, 2026 until launch may qualify. No money is paid until the program launches and your application is approved. Receipts must be submitted within 6 months.
• Heating fuel. Homes heated by electricity (including baseboards and electric furnaces), natural gas, oil, propane, diesel, coal or wood all qualify.
• One per address. Federal funding must not previously have been provided for a heat pump at the address.

The income line is after-tax household income, compared against a limit for your province and household size. The Nova Scotia limits:

The federal page does not say whether the rebate can be combined with provincial programs. Efficiency Nova Scotia's June 2026 guide predates the announcement. Nothing published forbids stacking NHPR on HEA and MIR, but nothing confirms it either. The worked examples below show the combined arithmetic as an addition and flag it as provisional. The program record is on our National Heat Pump Rebate page.

One more practical point. The 6-month receipt window and the early 2027 portal mean a heat pump installed in November 2026 waits several months for its federal money. Budget for carrying the full cost until then.

What Has Closed, and What That Means for Your Quote

Contractors' brochures and older web pages still quote two federal programs that a new applicant cannot use.

Oil to Heat Pump Affordability (OHPA). In Nova Scotia it was co-delivered with Efficiency Nova Scotia and paid up to $15,000, which could be combined with HEA and MIR for a possible $25,000. In December 2025 Natural Resources Canada told The Canadian Press that Nova Scotia's funding would be fully committed in 2026 and set up a standby list. The federal OHPA page gives July 31, 2026 as the last day to apply only for residents of Alberta, Manitoba, the Northwest Territories, Quebec and Saskatchewan, and it sends Nova Scotians to the participating-provinces page, which lists no Nova Scotia closing date. Our own program record shows the Nova Scotia stream closed to new applicants on July 2, 2026; we could not confirm that date on the federal pages, so check with Efficiency Nova Scotia before you count on a late application. The federal OHPA page sets January 31, 2027 as the deadline for final receipts in the provinces it covers; if you were approved earlier, check your approval letter for your own deadline, finish the work and file on time; if you were not, plan around HomeWarming, MIR and the federal rebate instead. Details are on our OHPA program page.

Canada Greener Homes Loan. The interest-free federal loan of $5,000 to $40,000 is fully committed and no new loans can be approved. Its last day to apply was October 1, 2025. See the Canada Greener Homes Loan record. In Halifax, the HalifACT financing at 4.75% is the nearest replacement; elsewhere, ask your municipality and credit union.

A useful test for any quote: if it lists "Greener Homes" or "OHPA" as a deduction from the price, and you have no approval letter, the deduction is not real.

Running Costs on Nova Scotia Power's 2026 Rate

A rebate shortens payback; the electricity rate decides whether there is a payback at all. Nova Scotia Power's standard residential energy charge has been 19.128 cents per kWh since May 1, 2026, up from 18.187 cents. The cost of heat from each source works out like this.

Electric baseboard. Every kWh of electricity becomes one kWh of heat, so heat costs 19.1 cents per kWh.

Heat pump. Heat costs the electricity rate divided by the seasonal coefficient of performance (COP). The COP is an assumption, not a published Nova Scotia figure; a cold-climate unit in a coastal climate commonly lands between 2 and 3 across a season, and our cold-climate performance data shows how it falls with outdoor temperature.

Heating oil. A litre of heating oil holds about 10.7 kWh of energy (138,500 BTU per US gallon, the standard U.S. Energy Information Administration heat content, divided by 3.785 litres and by 3,412 BTU per kWh). An older oil furnace or boiler running at an assumed 80% seasonal efficiency delivers about 8.58 kWh of heat per litre. Furnace oil prices in Nova Scotia are not regulated and move weekly, so the table shows a range rather than one price.

The break-even is low. At a COP of 2.5, the heat pump's 7.7 cents equals oil at about 66 cents a litre (7.65 cents times 8.58 kWh). At a COP of 2.0 the break-even is about 82 cents. Oil has not been that cheap at a Nova Scotia retail pump in years, so for an oil-heated home the question is how large the saving is, not whether there is one.

Nova Scotia Power's Time-of-Day plan, with an off-peak rate of 12.436 cents, is offered to customers with electric thermal storage heating; its page does not list heat pumps as a qualifying system, so do not count on it for a heat pump payback.

Worked Example 1: An Oil-Heated House in Dartmouth

These are hypothetical households built to show the arithmetic. Every rebate rate comes from the program documents cited above; the quote, the oil use and the oil price are labelled assumptions.

The house. A 1,600 square foot two-storey home with an oil furnace and working ductwork. It burns an assumed 2,400 litres of oil a year. The owners plan a 3-ton centrally ducted cold-climate heat pump, with electric backup, and remove the oil system. The attic sits at R-12 and the basement walls are bare concrete.

The quote (assumed). $14,000 for the heat pump with electrical work, plus $3,200 for attic insulation to R-50 and $4,800 to insulate the full basement wall to R-22. Total: $22,000.

Step order. Book the HEA first. Apply for MIR pre-approval if eligible. Sign the contract only after the initial assessment, and install after November 1, 2026 so the federal rebate also applies.

Household A: income above both limits. Two adults, after-tax income $110,000, so above the federal $80,300 limit for two and assumed above the MIR limit.

Household B: moderate income. Two adults, after-tax income $72,000, so below the federal limit, and assumed within the MIR limit.

Look at what the cap did. The MIR lines added to $5,250, so $250 fell off. This table also takes the conservative reading of the stacking note: the MIR heat pump rebate replaces the HEA heat pump rebate. If your advisor confirms both apply, add $1,500 and the net cost falls to $3,350. And the federal amount is "up to" $10,000, varying with equipment cost: if Environment and Climate Change Canada limits the payment to the heat pump's own cost after other rebates, Household B could get less than the full $10,000 against a $14,000 heat pump that already earned $4,500 or more from the province.

Running cost. 2,400 litres at 8.58 kWh of delivered heat each is about 20,600 kWh of heat a year. At a COP of 2.5 the heat pump needs about 8,240 kWh, which costs $1,576 at 19.128 cents. The oil bill at an assumed $1.50 a litre is $3,600, so the saving is about $2,024 a year; at $1.75 a litre it is about $2,624. Taxes apply to both bills and are left out on both sides.

Payback. Household A: $16,350 divided by about $2,000 to $2,600 a year is roughly 6 to 8 years, though the insulation share of that cost also lowers the heat load, so the true figure is a little better. Household B: $4,850 divided by the same savings is about 2 to 2.5 years.

Worked Example 2: A Baseboard-Heated Bungalow in Truro

The house. A 1,100 square foot bungalow heated by electric baseboards, using an assumed 14,000 kWh a year for space heat. The owner installs one 1.5-ton single-zone ductless heat pump in the open living area, assumed to carry 60% of the heating load, and keeps the baseboards in the bedrooms.

The quote (assumed). $5,500 installed, within the national single-zone range we cite in our mini-split installation cost guide.

What the programs pay.

The MIR column is zero because MIR excludes electrically heated homes. That is the single biggest difference between the two examples. If the owner's income is under the HomeWarming limit ($29,580 for one person), HomeWarming could install the heat pump at no cost, and the HEA and federal lines would not apply to that same unit.

Running cost. The heat pump carries 60% of 14,000 kWh, or 8,400 kWh of heat. Baseboards would use 8,400 kWh of electricity for that; the heat pump at a COP of 2.5 uses 3,360 kWh. The 5,040 kWh saved is worth $964 a year at 19.128 cents.

Payback. For the above-limit owner, $3,050 divided by $964 is about 3.2 years. A baseboard home often reaches payback faster than an oil home in net-cost terms because the single-zone install is cheap, even though its rebate is smaller.

What not to do. Do not replace a working heat pump to collect rebates. HEA pays only on added capacity, and the federal rule against a second federally funded heat pump at the same address means a home that already used a federal program for its first unit may get no NHPR either.

Which Sequence Keeps Every Rebate Valid

1. Check HomeWarming first if household net income is near $29,580 (one person), $55,928 (two to four) or $77,571 (five or more).
2. Book the HEA and pay the $199 fee, or have it waived if you qualify as low to moderate income. Do not buy or install anything yet.
3. Ask the advisor about MIR if the home is heated mainly by oil, propane or wood. Get written pre-approval.
4. Get three quotes on the scope in your report. Our quote comparison worksheet keeps them on the same basis. Confirm the heat pump model is on the federal eligible products list by its AHRI number.
5. Install on or after November 1, 2026, and after your initial assessment. Keep every invoice.
6. Book the final assessment within 12 months of the first.
7. File the federal application when the portal opens in early 2027, within 6 months of having your receipts.

Insulation goes before or with the heat pump, not after. A smaller heat load means a smaller heat pump, a lower quote, and a higher share of the heat covered by the heat pump rather than backup. Our insulation payback guide works through the order for cold climates.

Edge Cases That Trip People Up

The house is new. The HEA requires a home at least 6 months old.

You already started. Work done before the initial assessment earns no HEA or MIR rebate. There is no retroactive claim.

You rent. HomeWarming excludes rentals, and the HEA and MIR require an owner. A tenant's route is through the landlord.

You heat with oil but mostly use a wood stove. MIR asks what heats the house primarily. An advisor will record that at the first visit. Be accurate, because the answer decides a $1,500 per ton difference.

Your panel is full. Electrical upgrades are part of many heat pump jobs, and HEA does not list a rebate for them. Price them separately; our panel upgrade cost guide has ranges.

A door-to-door seller says the government sent them. The federal program page warns that Environment and Climate Change Canada does not go door to door or make marketing calls. Our heat pump scam guide lists the common lines.

Frequently Asked Questions

How much can I get in Nova Scotia home energy rebates in 2026?

Up to $5,000 from the Home Energy Assessment program, up to $5,000 more from the Moderate Income Rebate if your home is heated mainly by a non-electric fuel and your income qualifies, and $2,000 or up to $10,000 from the federal National Heat Pump Rebate for heat pumps installed from November 1, 2026. Low-income owners can have upgrades installed free through HomeWarming. Amounts checked November 13, 2026.

Is the Nova Scotia oil to heat pump rebate still available?

No, not for new applicants. The Oil to Heat Pump Affordability program's Nova Scotia funding was committed in 2026 (Natural Resources Canada said so in December 2025, and our own record shows the Nova Scotia stream closed to new applicants on July 2, 2026). If you were already approved, check your approval letter for your final-receipt deadline. Oil-heated homes can still use HEA, MIR, HomeWarming and the federal National Heat Pump Rebate.

Can I combine the federal heat pump rebate with Efficiency Nova Scotia rebates?

Nothing published prohibits it, but nothing confirms it. The federal program page, modified November 5, 2026, does not address provincial stacking, and Efficiency Nova Scotia's June 2026 guide predates the federal program. The federal rule that does apply is one heat pump per address funded by a federal program.

Does an electric baseboard home qualify for heat pump rebates in Nova Scotia?

Yes, for HEA ($300 per ton ductless, $500 per ton ducted, on added capacity) and for the federal rebate, which lists electric baseboards among eligible heating types. It does not qualify for the Moderate Income Rebate, which excludes electrically heated homes.

How much does a Home Energy Assessment cost in Nova Scotia?

$199 for the initial assessment, free for low- to moderate-income households. Efficiency Nova Scotia's guide says participants in the Moderate Income Rebate are entitled to a free assessment, reimbursed if paid upfront.

How long do I have to finish the work?

Twelve months from the initial assessment to the final assessment, with extensions possible through your Registered Energy Advisor. Rebate cheques generally arrive within 90 days of the final assessment.

What are the HomeWarming income limits?

The March 2025 application form sets annual household net income limits of $29,580 for one person, $55,928 for two to four people, and $77,571 for five or more, taken from line 236 minus line 435 of the Notice of Assessment.

What does electricity cost in Nova Scotia for a heat pump?

The standard residential energy charge is 19.128 cents per kWh plus a $20.08 monthly basic charge, in effect since May 1, 2026. A heat pump with a seasonal COP of 2.5 turns that into heat at about 7.7 cents per kWh.
