About these calculators
CanWeFind works out what things cost to run on your own rates, rather than on a national average that describes nobody's house.
Where the figures come from
Every default rate comes from a named regulator or statistical agency — never a supplier's marketing page, never a comparison site's average, never an estimate. Each is dated on the page it appears on.
How often they are replaced
Rather than relying on someone remembering, the site refuses to publish once any country's figures pass their review date: the build fails, and it warns for three weeks beforehand. A page quoting last quarter's rate cannot quietly sit here for a year.
Rates live in one file rather than being written into each calculator, so an update reaches every page in that country at the same moment. There is no version of this site where one calculator is current and another is not.
Why each country reads differently
These are not translations of a British page. Billing works differently in each country — a daily standing charge is a British and Irish idea, American utilities use a fixed monthly customer charge, and rates vary far more between US states than between British suppliers. Where a tool would not make sense in a country, it simply is not offered there.
If a figure looks wrong
Email hello@canwefind.com and say which page and which number. Corrections are made at the source, so a fix applies everywhere at once rather than to the one page that was reported.
What this is not
These are estimates for comparing options — not financial advice, not a quote, and not a substitute for your bill. Appliance wattages vary between models, thermostats cycle on and off, and tariffs carry terms this cannot see. Check anything that matters against your own account before acting on it.
