Meter values, dates, rates and notes are stored only in this browser using local storage. There is no account, supplier connection or data upload.
This is a personal estimate, not a bill. Meter types, conversions, standing charges, tariffs and billing periods vary. A grown-up must copy readings carefully and check all costs against the supplier’s official information.
Build your own with AI
“Build me a mobile-friendly household meter tracker in one standalone HTML file. Include separate electricity, gas and water tabs. Let me add dated cumulative readings, unit labels, an optional unit rate in pence and notes. Calculate usage and days between consecutive readings, estimate interval cost, draw a simple usage chart, show history, allow deletion and printing, and save everything only in local browser storage. Clearly state that it is not an official bill.”
