Rated input provides a comparable upper-use scenario. Actual consumption changes as compressors cycle, so this page never promises a fixed bill saving.

Match capacity first, then compare verified rated watts with one tariff and usage assumption. The lowest wattage is not automatically cheapest in practice if the unit is undersized and must run longer.
Price evidence is labelled as current or last seen. Confirm the exact model, seller, delivery and availability before buying. The table scrolls horizontally on smaller screens.

Ordered by verified rated input watts, then cooling output per rated watt. The hourly illustration uses 25p/kWh and should be replaced with your own tariff in the calculator.

Open decision cardAdd to comparisonThe same model can be a sensible fit in one room and a poor fit in another. Use these scenarios to decide which evidence to collect next.
Rated watts multiplied by your tariff gives a transparent cost-per-hour ceiling while the compressor is drawing that input. It does not mean the unit consumes the same amount every hour. Compare models on the same basis and label the result as a scenario rather than a bill forecast.
Consumption can fall when the compressor cycles, but duty cycle depends on room load, set point, outdoor conditions, sealing and capacity. Do not assume an arbitrary low percentage to manufacture savings. Test a cautious range and keep the rated-input result visible beside it.
A lower energy scenario may not recover a large purchase-price difference during occasional use. Combine the energy calculation with delivery, window accessories and expected ownership years. Warranty terms and service support matter, but CoolCompare does not convert them into an unsupported reliability claim.
Not necessarily. An undersized unit may run for longer and fail to reach comfort. Match capacity first, then compare rated input under one usage scenario.
It is an editable illustration, not a live national tariff. Use the running-cost calculator with the rate on your bill or tariff document.
A shortlist position cannot tell you whether a product fits your room, window or tolerance for compressor noise.
