Our calculation method

Electrical energy in kWh equals power in kW multiplied by hours of use. Cost in pounds equals kWh multiplied by pence per kWh divided by 100. We use 365 days a year, 365/7 weeks and 12 months. We round displayed currency only.

The reference electricity rate

The default of 26.32p/kWh is the published GB average direct-debit electricity unit rate for 1 October–31 December 2026, checked 7 November 2026. It is an example, not your personal tariff. Rates vary by region, payment method and contract; Northern Ireland has a different market. Ofgem source.

What an appliance label tells you

Energy labels may use kWh/year, kWh/cycle or kWh/100 cycles. The tool asks for the unit explicitly. Test programmes and scales differ; compare like-for-like capacity and programme. UK Government energy labelling guidance.

Illustrations are not measurements

Preset wattages and cycle values are editable examples, not measured averages or verified product specifications. Thermostats, loads, ambient temperature and standby use can change actual consumption. Standing charges are excluded because an extra appliance does not generally add an extra daily standing charge.

How commercial information is published

Only records from owner-approved licensed sources pass into the commercial catalogue. They require model identity, energy basis, source evidence, verification and expiry dates. Expired offers are hidden. Prices are snapshots; confirm them with the retailer. We do not invent customer ratings or hands-on tests.

Editorial automation

Local AI may propose changes for owner review. It cannot publish unsupported claims. Validated structured data can update automatically; rejected records are held in the owner dashboard. A source check confirms a recorded source, not independent laboratory testing.
