What the scanner extracts from your bill

When you upload a photo or PDF, the AI reads your bill and pulls out the key details: your supplier name, tariff type (fixed or variable), electricity and gas unit rates in pence per kWh, standing charges in pence per day, your total consumption in kWh, billing period, and contract end date where shown. It then compares your rates against the current Ofgem price cap for your region.

How to read your energy bill

Every UK energy bill has two main charges. The unit rate is what you pay per kilowatt-hour (kWh) of gas or electricity you actually use - under the April 2026 Ofgem cap that is around 24.5p/kWh for electricity and 6.76p/kWh for gas. The standing charge is a fixed daily fee you pay just for being connected to the grid, even if you use nothing at all - roughly 61p/day for electricity and 32p/day for gas.

Why this matters

The Ofgem price cap sets the maximum your supplier can charge on a default tariff, but it does not mean you are on the cheapest deal. Fixed tariffs from smaller suppliers regularly beat the cap by £100-250 a year. If the scanner shows your unit rates sitting at or above the cap, there is almost certainly a cheaper deal available. You do not need to switch to use this tool - but knowing your numbers is the first step.

Frequently asked questions

What file types does the scanner accept?

PNG, JPG, and PDF. It works with bills from all major UK suppliers - British Gas, Octopus, E.ON, EDF, OVO, Scottish Power, and most smaller suppliers. Any clear photo or scan will work.

Is my data safe?

Yes. Your bill image is sent to the analysis API and is not stored after processing. We extract only the rate information needed - supplier, unit rates, standing charges, consumption, and region. No account numbers, payment details, or personal data are saved.

What if the AI misreads something?

AI extraction is accurate for the vast majority of standard UK bills but can occasionally misread unusual layouts, handwritten notes, or low-resolution images. Always check the extracted figures against your original bill. If something looks wrong, try uploading a clearer photo or a PDF version for better results.

Do I have to switch supplier to use this?

No. The scanner is completely free with no obligation to switch. It breaks down what you are currently paying so you can understand your bill. If the analysis shows you could save, that is your choice.
