FREQUENTLY ASKED QUESTIONS

Clear answers before you calculate.

Short answers about the tools, assumptions and privacy choices behind Garage & Grid.

Are the calculators a quote or personal advice?

No. They are planning estimates using the assumptions you enter. Check your current electricity plan, vehicle details, fuel price and any supplier quote before making a decision.

Do you keep my calculator inputs?

No. Your calculator inputs stay in your browser. Garage & Grid does not ask for an account or send those values to Google Analytics.

Which calculator should I start with?

Use EV running cost for yearly charging, Charging cost for one charging session, and EV vs petrol / hybrid to compare purchase and ownership assumptions over time.

Why are electricity and fuel prices editable?

Your tariff, charging mix and local fuel price can differ from a starting reference. Editable inputs make the estimate more useful than a fixed national average.

How can I flag a problem or suggest an improvement?
