What is your attic upgrade worth?

1 / What can you get back?

Use the added R-value. Then apply the cap.

R-value measures resistance to heat flow. If the existing insulation is assessed at R20 and the proposed finished level is R50, the addition is R30. Ask for the starting and finished values separately; adding R30 and finishing at R30 mean different things.

For the standard utility attic offer, the starting calculation is $0.02 × eligible attic square feet × R-value added, capped at $900. The minimum addition is R12. If old insulation is removed, the starting value is not automatically zero: the program accounts for the previous insulation. Rebates cannot exceed the eligible paid cost. FortisBC calculation and requirements ↗

Use the attic’s qualifying insulated area, not the total floor area advertised in a real-estate listing. A two-storey house does not necessarily have an attic as large as both floors combined. Ask for the measured area, the documented existing insulation and the proposed increase on the quote. Those three numbers make the rebate estimate reviewable.

A larger rebate is only one part of value. Buying unnecessary work to reach a maximum is not a saving. Compare the proposed improvement with the actual condition of your attic and the total amount you would pay.

Could you qualify for more help?

FortisBC’s separate income-qualified rebate

The current attic rate is $0.05 × square feet × R-value added, up to $2,000, with at least R12 added. For example, an eligible 1,200-square-foot attic gaining R30 calculates to $1,800 before cost limits. This is a different offer from the standard table above.

For a Lower Mainland natural-gas customer, check household income, the FortisBC account and home restrictions. The home must be at least 10 years old, no larger than 3,500 square feet, and assessed below $1.2 million. Registered owners must be on the account and own only one B.C. property. A four-person household’s published income ceiling is $94,900; other household sizes have different limits. Applications are due within six months of the invoice. This offer cannot be combined with other FortisBC, provincial or federal rebate programs. Full FortisBC income-qualified requirements ↗

ECAP: assistance rather than a cash-back quote

The Energy Conservation Assistance Program may provide an evaluation and approved insulation, weatherization or other upgrades at no cost for eligible households. Apply through the program first. Its evaluation determines which upgrades, if any, are suitable, and the program arranges delivery. Funding and eligibility limits apply. BC Hydro and FortisBC assistance-program details ↗

This is not a promise that a separately commissioned PSI installation will be reimbursed. If assistance is your preferred route, get the program’s decision before buying work privately.

2 / Check the route before booking

Your heating system matters more than your postal code.

For BC Hydro’s route, the home must meet its electric-heating, utility-account and property requirements. Municipal electricity customers in its territory, including New Westminster, can be included. Natural-gas-heated homes should check the FortisBC route instead. Eligible existing homes and individual accounts are treated differently from condominium buildings, strata accounts, outbuildings and new construction. BC Hydro’s full eligibility checklist ↗

The insulation offer requires an HPCN member contractor; do-it-yourself installation is not eligible. BC Hydro lists eligible material types and installation conditions, including the treatment of removed insulation, pest issues and certain permit-driven renovations. Its application deadline is six months from the invoice date. Installation and application requirements ↗

Before accepting a rebate-based quote, verify the installing business’s current insulation listing in the Home Performance Contractor Network directory and confirm the applicable program. This guide does not certify PSI’s network status or approve your application. Ask PSI to establish both the project scope and the rebate route before work is authorized.

3 / Specify what goes into the attic

“Spray-in” can mean different things.

Homeowners often use “spray-in” for any insulation delivered through a hose. Blown-in loose-fill insulation and spray polyurethane foam are different systems. NRCan describes loose-fill options including cellulose, glass fibre and mineral fibre. Loose-fill can suit accessible attic top-ups; the product’s coverage, thickness and installation requirements still matter. NRCan’s insulation-material guide ↗

Start the PSI conversation with the problem: a cold upper floor, uneven coverage, a proposed top-up or a roof-space renovation. Ask which material is proposed, where the insulated boundary will be and why that approach suits your building. A brand name or a high R-value on its own does not explain the complete scope.

NRCan’s attic guidance treats air sealing, insulation and ventilation together. In a vented attic, adding insulation must not block the intended ventilation at the eaves. Moisture, roof defects and unsafe existing conditions need attention before they are covered. An attic-floor top-up and insulation beneath roof sheathing require different design decisions. NRCan’s roofs-and-attics guide ↗

Ask who is checking the hatch, penetrations, ventilation path and existing material, and which preparatory work is included. Where an existing material or condition needs specialist investigation, agree that next step before installation. This article is a buying guide; the illustration does not specify clearances, thicknesses or a roof assembly.

4 / What is the value to you?

Separate the rebate from the ongoing savings.

A rebate reduces your initial outlay. Reduced heating demand can affect future running costs. Comfort is another outcome to discuss, especially if upper rooms feel different from the rest of the home. Those benefits are related, but they should not be combined into an unsupported “pays for itself” promise.

No savings percentage is assigned to your home here. A lightly insulated, leaky attic is a different starting point from one already well insulated. Heating equipment, air leakage, thermostat settings, weather and occupancy also matter. A review of bills and a home-specific energy assessment can give the discussion a firmer basis than a generic percentage.

For a useful comparison, ask each bidder to price the same area, preparation and target insulation level. Keep optional removal, repairs and access work visible as separate items. A lower headline price can represent a smaller scope; a larger rebate estimate can reflect a different assumption about the starting R-value.

Are there extra rebates for a bigger renovation?

BC Hydro lists a $300 Two Upgrade Bonus and a separate $750–$2,000 Home Energy Improvement Bonus for qualifying projects under its standard renovation route. The bonuses cannot be combined. Attic work counts toward bonus eligibility only when its rebate reaches at least $500. The larger bonus requires pre- and post-upgrade EnerGuide evaluations and at least three qualifying upgrades. Check the sequence and deadlines before starting. Current bonus rules ↗

These are whole-project offers, not extra money automatically attached to a single attic top-up. Ask the program to confirm how your proposed package qualifies. Keep each rebate, each upgrade cost and any assessment fees separate in the budget.
