Home improvements in Ottawa can be expensive.

Whether you're planning to upgrade your insulation, install a heat pump, protect your basement from sewer backups, improve drainage, or make your home more energy efficient, there may be financial assistance available.

The challenge is knowing which program applies to your project, whether you qualify, and what you need to do before the work begins.

Ottawa homeowners may have access to programs offered by the City of Ottawa, the Province of Ontario, local utilities and federal programs delivered through provincial partners. Some provide rebates after eligible work is completed. Others provide free upgrades to qualifying households, while some offer long-term financing instead of a traditional rebate.

This guide brings together some of the major programs Ottawa homeowners should know about in 2026 and explains what they may cover, who they are designed for and what to watch for before starting a renovation.

Important: Program budgets, eligibility requirements, rebate amounts and deadlines can change. Always confirm the current requirements with the official program administrator before signing a contract, paying a deposit or starting construction.

Looking for Ottawa homeowner rebates? Start here

If you're planning a renovation, the right program depends largely on what you're trying to accomplish.

For insulation, homeowners should investigate programs such as Home Renovation Savings, Better Homes Ottawa, the Energy Affordability Program and the Home Winterproofing Program.

For a heat pump, Home Renovation Savings and Better Homes Ottawa are two important programs to investigate.

If your concern is basement flooding, Ottawa offers programs covering measures such as sump pumps, backwater valves and rainwater management through Rain Ready Ottawa and the Residential Protective Plumbing Program.

And if you have already experienced qualifying sewer-related flooding, the City's Compassionate Grant Program may provide financial assistance for some recovery costs.

The important thing is to investigate the program before you begin the work. Some programs require an assessment, permit or written approval in advance.

1. Better Homes Ottawa: A financing option for larger home improvements

The Better Homes Ottawa Loan Program is designed for Ottawa homeowners planning larger energy-efficiency and climate-resiliency improvements.

Unlike a traditional rebate, the program provides long-term financing that can be used for eligible improvements to the home.

The City currently advertises a 20-year loan at 4.33% interest for eligible energy-efficiency and climate-resiliency renovations.

What can Better Homes Ottawa help finance?

Depending on eligibility and program requirements, eligible improvements can include:

• Attic, wall, foundation and basement insulation

• Air sealing and weather stripping

• Energy-efficient windows and doors

• Air-source heat pumps

• Ground-source heat pumps

• Ventilation systems

• High-efficiency water heaters

• Solar panels

• Battery storage

• Level 2 EV chargers

• Electrical upgrades associated with eligible retrofits

• Backwater prevention valves

• Sump pumps

• Basement waterproofing

• Permeable pavement

• Tree planting

• Certain permit and assessment costs

This makes Better Homes Ottawa particularly interesting for homeowners who are considering multiple improvements at the same time.

The City also confirms that the Better Homes Ottawa loan can be combined with other energy-efficiency rebate, incentive and financing programs, including Home Renovation Savings, subject to the individual program rules.

Better Homes Ottawa and heat pumps

Homeowners participating through Better Homes Ottawa may also have access to heat-pump incentives depending on the current program requirements.

Because heat-pump incentives can depend on equipment specifications, efficiency ratings and installation requirements, homeowners should confirm the exact eligibility requirements before purchasing equipment.

Who should consider Better Homes Ottawa?

This program may be particularly useful if you're planning a larger retrofit involving several improvements, such as:

insulation + air sealing + heat pump + basement protection + solar

rather than simply looking for a small one-time rebate.

Best for: Homeowners planning a larger energy-efficiency or climate-resiliency project who want financing rather than relying entirely on upfront cash.

2. Rain Ready Ottawa: Rebates for managing rainwater on your property

Heavy rainfall can create significant problems for Ottawa homeowners.

Water can collect around foundations, overwhelm drainage systems, run toward neighbouring properties or contribute to basement flooding.

Rain Ready Ottawa is designed to help homeowners manage rainwater where it falls by encouraging improvements such as downspout redirection, rain gardens, soakaway pits and permeable surfaces.

The current residential program advertises rebates of up to $5,000, although the maximum depends on the specific project.

Downspout redirection

The current program lists a rebate of up to $1,000 for qualifying downspout-redirection projects.

The goal is to move roof runoff away from the foundation and toward an appropriate area where it can safely infiltrate.

Rain gardens

Rain garden projects may qualify for up to $2,500.

A rain garden is a landscaped area designed to temporarily collect and infiltrate rainwater rather than allowing all of that water to flow directly toward municipal drainage systems.

Soakaway pits

Soakaway pit projects may qualify for up to $2,500.

These systems temporarily collect runoff underground and allow it to gradually infiltrate into the surrounding soil.

Permeable pavement

Qualifying permeable pavement projects may receive up to $5,000.

This can be particularly relevant for homeowners considering a new driveway, walkway or patio.

Certified landscape design

A qualifying certified landscape design may also be eligible for a $500 rebate, subject to the program requirements.

The current residential program identifies five eligible practices:

1. Downspout redirection

2. Rain garden installation

3. Soakaway pit installation

4. Permeable pavement

5. Certified landscape designs

Is your property eligible?

Rain Ready Ottawa rebates are targeted to properties located within designated Priority Stormwater Retrofit Areas.

The City provides an online Rain Ready Ottawa eligibility checker where homeowners can enter their address and determine whether their property is in an eligible area.

An important Rain Ready Ottawa rule

One of the biggest things homeowners need to know is that Rain Ready Ottawa is not retroactive.

You must submit your application and have your project approved before starting construction.

The City also requires an applicable assessment, certified professional involvement or completion of designated eLearning courses, depending on the project.

Best for: Homeowners dealing with runoff, standing water, drainage concerns or looking for ways to reduce the amount of rainwater flowing toward their foundation.

3. Residential Protective Plumbing Program: Help with sump pumps and backwater valves

Rainwater isn't the only source of basement flooding.

Sewer backups can also cause significant damage, particularly during major rainfall events when municipal systems become overloaded.

Ottawa's Residential Protective Plumbing Program provides financial assistance for certain protective plumbing improvements.

The program can help with measures such as:

• Indoor sanitary backwater valves

• Storm backwater valves

• Outdoor storm backwater valves

• Sump pumps

• Battery backup systems

• Construction of a new sump pit

The Residential Protective Plumbing Program can provide financial assistance for several basement flood-protection measures. Eligible homeowners may receive 100% of the current plumbing-work building permit fee, up to $1,000 for an indoor sanitary backwater valve, up to $1,000 for a storm backwater valve, and up to $2,500 for an outdoor storm backwater valve. For sump pumps, the program offers up to $1,500 per pump when a battery backup is installed in an existing sump pit, or up to $3,000 per pump when the project includes a battery backup and construction of a new sump pit. The City generally reimburses the lesser of the applicable maximum rebate or the actual eligible cost.

Don't install first and ask about the rebate later

This is particularly important with protective plumbing work.

A building permit and inspection are part of the process, and documentation such as proof of ownership, permits, inspection reports and paid itemized invoices may be required.

Best for: Homeowners looking for practical protection against sewer backups and basement flooding.

Official information: Residential Protective Plumbing Program – City of Ottawa

4. Compassionate Grant: Assistance after qualifying sewer-related basement flooding

If your Ottawa home has already experienced qualifying basement flooding caused by a sewer surcharge event, the Compassionate Grant Program may provide a one-time $1,000 payment, subject to the current program requirements.

This is not general flood insurance and does not cover every type of water damage.

Eligibility depends on the cause of the flooding and other program requirements.

Homeowners should keep documentation such as:

• Dated photographs

• Insurance documentation

• Cleanup invoices

• Repair invoices

• Equipment-rental receipts

• Waste-disposal receipts

• Water-removal costs

If your home experiences basement flooding, don't wait to report it or start throwing away documentation.

Best for: Ottawa homeowners or tenants recovering from qualifying sewer-related basement flooding.

Official information: Compassionate Grant Program – City of Ottawa

5. Home Renovation Savings: Ontario rebates for insulation, heat pumps and energy upgrades

For many Ottawa homeowners, the Home Renovation Savings Program is one of the most important programs to investigate.

The program is delivered through Enbridge Gas and Save on Energy, with support from the Ontario government.

The program includes both upgrades that can be completed without a home energy assessment and bundled upgrades that involve an assessment.

The Home Renovation Savings Program offers a range of rebates for eligible home improvements. Homeowners may receive up to $7,700 for attic, wall, foundation or exposed-floor insulation, up to $12,000 for qualifying heat pumps, and up to $10,000 for solar panels and battery storage. Other available incentives include $1,250 for attic insulation through the no-assessment pathway, $100 for a smart thermostat, $500 for a heat-pump water heater, up to $250 for air sealing, $100 per rough opening for eligible windows and doors, and up to $200 for qualifying appliances. The exact rebate amount depends on the specific project, equipment, eligibility requirements and program stream, so homeowners should confirm the current details before purchasing equipment or starting work.

Insulation rebates

Homeowners interested specifically in attic insulation can review the Home Renovation Savings attic insulation program.

The program explains that attic insulation can improve comfort and reduce heat loss in winter and unwanted heat gain in summer.

Heat pump rebates

Homeowners considering a heat pump can review the Home Renovation Savings heat-pump program.

The program currently advertises rebates of up to $12,000 for qualifying heat pumps.

Solar and battery storage

Homeowners considering solar can review the Home Renovation Savings solar program.

The current program advertises up to $5,000 for solar panels, with the possibility of an additional rebate for battery storage.

Why the order of renovations matters

For homeowners planning several improvements, the program can be especially valuable.

For example, improving insulation and air sealing before upgrading heating equipment can reduce the home's heating and cooling load and potentially make a heat-pump project more effective.

Best for: Homeowners looking for rebates for insulation, heat pumps, windows, doors, air sealing, solar, battery storage and selected appliances.

6. Energy Affordability Program: Free energy upgrades for qualifying households

Not every homeowner has the ability to finance a major renovation.

The Energy Affordability Program is designed to provide no-cost energy-saving products and upgrades to eligible income-qualified Ontario households.

Depending on the household and home, improvements may include:

• LED lighting

• Energy-efficient refrigerators or freezers

• Dehumidifiers

• Window air conditioners

• Smart power strips

• Efficient showerheads

• Faucet aerators

• Attic insulation

• Basement insulation

• Draft proofing

• Programmable or smart thermostats

• In some circumstances, cold-climate air-source heat pumps

The program currently offers free cold-climate air-source heat pumps to certain income-eligible households using electric or oil heating.

Who should check this program?

This program is particularly worth investigating if your household meets the income or qualifying-benefit requirements.

Best for: Homeowners who qualify for income-based assistance and want energy improvements without a large upfront cost.

Official information: Energy Affordability Program – Save on Energy

Application: Energy Affordability Program Application

7. Home Winterproofing Program: Free insulation and draft proofing for eligible households

The Home Winterproofing Program is another program worth checking for eligible Ontario households.

Rather than providing a simple cash rebate, the program can provide eligible households with no-cost upgrades through authorized delivery agents and contractors.

Potential improvements can include:

• Attic insulation

• Wall insulation

• Basement insulation

• Draft proofing

• Smart thermostats

• Other energy-saving measures where applicable

Enbridge Gas says eligible households may receive free insulation, draft proofing and other energy-efficient upgrades.

The current application process can also screen applicants for other applicable energy programs.

Best for: Eligible households looking for no-cost insulation, draft-proofing and home-comfort improvements.

How to avoid losing a rebate

One of the biggest mistakes homeowners can make is starting the renovation before understanding the program requirements.

Some programs require approval before construction. Others require a home energy assessment. Some require a building permit, while others require an approved contractor or specific equipment.

Before you sign a contract, consider taking these steps.

1. Check the official program

Start with the government or program administrator's website rather than relying entirely on a contractor's estimate of what you will receive.

Program rules can change.

2. Check eligibility before spending money

Don't assume that because a project sounds energy efficient, it automatically qualifies.

The specific product, contractor, property, location or installation method may matter.

3. Get required assessments and permits

If an EnerGuide assessment, building permit or other approval is required, complete it before starting the work.

Rain Ready Ottawa is a good example: the City specifically states that homeowners must have their project approved before construction because the rebates are not retroactive.

4. Keep your documentation

Save:

• Before and after photographs

• Quotes

• Contracts

• Paid invoices

• Permits

• Inspection reports

• Product specifications

• Model numbers

• Energy assessments

• Approval letters

5. Ask about combining programs

Some programs may allow you to combine financing with rebates, while others may not allow two rebates for the same improvement.

Better Homes Ottawa, for example, states that its loan can be combined with other energy-efficiency rebate, incentive and financing programs, but you should still confirm the rules for each specific program.

A smarter way to plan an Ottawa home retrofit

If you're planning several improvements, it can help to think about your home as a system rather than a collection of individual projects.

Start with the building envelope.

Look at areas such as:

• Attic insulation

• Basement and foundation insulation

• Air leakage

• Windows and doors

• Basement moisture

• Drainage and grading

Once you understand where the home's biggest problems are, you can make better decisions about mechanical upgrades such as heat pumps or water-heating equipment.

If water is a concern, consider both sides of the problem.

Rain Ready Ottawa focuses on managing rainwater around the property, while the Residential Protective Plumbing Program addresses protective plumbing measures such as sump pumps and backwater valves.

These are different approaches to reducing flood risk and may complement one another.

Final takeaway: Ottawa homeowners have options

There isn't one single Ottawa homeowner rebate that covers every renovation.

Instead, there are several programs that address different parts of home ownership.

For insulation and energy efficiency, investigate Home Renovation Savings, Better Homes Ottawa, the Energy Affordability Program and Home Winterproofing.

For heat pumps, compare the available Home Renovation Savings incentives with Better Homes Ottawa.

For rainwater and flood prevention, look at Rain Ready Ottawa and the Residential Protective Plumbing Program.

If you've experienced a qualifying sewer-related basement flood, check the Compassionate Grant.

The most important rule is simple:

Check before you start.

Confirm eligibility. Complete the required assessment. Get the necessary permits or approvals. Keep your documentation. And verify the current program requirements directly with the program administrator.

A few minutes of research before starting a project could make the difference between receiving valuable assistance and discovering afterward that your renovation didn't qualify.

Thinking about a home renovation in Ottawa?

Before you start, consider understanding the current condition of your home so you can prioritize improvements based on what the house actually needs—not simply what happens to have a rebate attached to it.
