Methodology
Planning estimates with visible assumptions
How HomeChargeGuide keeps calculator results useful, conservative, and clear about what still needs professional review.
Calculator boundaries
EV calculator outputs are planning estimates only. They should help you understand the likely shape of a home charging project before you talk to an installer.
Electrical capacity, permits, inspection requirements, and installation design must be confirmed by a licensed electrician or local authority.
Assumptions
Calculator defaults and local guidance should say what they are based on. When a number depends on local incentives, permit rules, utility programs, parking type, or provider evidence, the page should make that basis visible.
Volatile items such as incentives, permit rules, provider status, and prices need review before they are presented as current.
Local guides
Local pages should only exist when local information changes the answer. Utility rules, permit authorities, incentive availability, housing type, parking context, and cost assumptions can all matter.
Provider rankings, best-installer claims, featured placements, and comparison tables should not appear unless the provider information can be checked and disclosed clearly.
