How we calculate

Product data

All product values come from the public part of EPREL, the European Product Registry for Energy Labelling (© European Union). We download the full public register for each product group and rebuild the site regularly. Values are shown as the supplier declared them. Each model page links to its EPREL registration.

One page per label, not per model number

Manufacturers often register the same appliance many times under different model numbers, one per colour, handle or market. When two or more registrations of the same brand have identical label values (energy class, consumption, capacity, noise, dimensions and so on), we show them on one page and list every model number on it. Searching for any of those numbers leads to that page.

Running costs

Running cost = annual consumption (kWh) × household electricity price (€/kWh).

Rankings and percentiles

Models are compared only with models of the same type and size band, such as fridge-freezers of 300–399 litres or 8 kg washing machines, because the energy class itself already scales with size. Percentiles are shown only when a group has at least 20 models. “Lower than 82%” means 82% of the other models in the group have a higher value.

Phone and tablet durability score

For each smartphone and tablet we compute five percentiles within its device type: battery endurance per charge, battery lifespan in charge cycles, drops survived without defect, the EU repairability index and guaranteed years of software updates. The durability score is their average, from 0 to 100. It is our own summary to help comparison and is not an official EU rating. A score needs at least four of the five values.

Phone model numbers are matched to retail names using Apple’s “Identify your iPhone/iPad model” pages, Google’s Pixel model number list and the Google Play supported-devices catalogue. Where no match is found we show the name the supplier registered.

Spare parts and software updates

EU ecodesign regulations require manufacturers to keep certain spare parts available for a minimum number of years after the last unit of a model is placed on the market: 7 years for refrigerators (Regulation (EU) 2019/2019), dishwashers (2019/2022), electronic displays (2019/2021) and smartphones and tablets (2023/1670), and 10 years for washing machines and washer-dryers (2019/2023). Some parts have longer periods; the regulations list them. When the register shows that a model is no longer placed on the market, we calculate the earliest date until which parts must remain available.

Registration history

Each time we rebuild the data we compare every registration with the previous build. When a supplier changes a declared value, the change and its date appear on the model page.
