Take the data. It is not ours.
Everything on this site is compiled from public sources, so the compilation is published back openly. Take the whole file, or call the API for the part you want. CORS enabled, no key, no rate limit. Use it in your own tool, cite it in your own piece, or check our working.
Not sure, or want to check your own numbers? Just ask.
Ask about any bill, or put your postcode in. Free, nothing to fill in, and nothing you type leaves your browser.
Your postcode and your figures never leave this browser. If I cannot work out what you mean, those words are sent to be classified, and a bill photo goes only if you send one and confirm it. Nothing is stored either way. How that works.
Energy, water, broadband and mobile, council tax and insurance. Headline figures, full tables, support schemes, dated changes and every source URL.
Duty stacks by legal authority for 29 trade corridors in both directions, with effective dates.
Twelve addresses instead of two files. Household benchmarks, live energy tariffs by region, the Ofgem cap, a postcode lookup, the change log and the trade tracker. JSON or CSV, and every answer carries its own sources and caveats.
Use it commercially, change it, build on it. Just credit Tariff Tracker and keep the links to the original regulators intact.
A plain summary of what is here and where to find it, at the root, in the format models look for.
Postcode area to electricity region, water company and council tax band ratios. Verified against the industry grid supply point mapping.
Never be surprised by a bill again.
