How to start a home-energy advising business in Ontario

Energy advisors run home energy evaluations — the EnerGuide rating that unlocks retrofit rebates and proves new-build performance. It is one of the most accessible standalone businesses in the built environment, riding the home-retrofit and energy-rebate wave.

The steps to start your practice

  1. 1

    Register your energy-advising business

    Register as an individual or incorporated entity, affiliate with (or build toward becoming) an NRCan-licensed Service Organization, and carry E&O and general liability. Then you can deliver EnerGuide evaluations for retrofit-rebate and new-build clients.

  2. 2

    Incorporate (or form a professional corporation)

    Most professionals incorporate to limit liability and for tax efficiency. Several regulated professions (architects, engineers) can form a professional corporation with a Certificate of Authorization — confirm the right entity type with your regulator before filing.

  3. 3

    Set up your CRA accounts

    Register for a Business Number, HST/GST (mandatory above $30,000 in revenue), payroll if you will hire, and corporate income tax. Professional service fees are HST-taxable.

  4. 4

    Carry professional liability (E&O) insurance

    Errors & omissions insurance is the core coverage for a professional practice — and a firm-authorization condition for regulated professions. It protects against claims arising from your professional advice, designs, or certifications.

  5. 5

    Stand up your practice operations

    Business banking, professional accounting, engagement letters and contracts, and the project and document workflows a practice runs on. This is the back office that keeps you paid and protected.
