Terms of Use

What this site is
SmartTechDay publishes independent calculations of what devices cost to run. We are not a retailer or a utility, we are not affiliated with any manufacturer named on this site, and we earn nothing from what you decide to buy.
Accuracy
Wattages and tariffs are quoted from the sources named beside them, with dates. Electricity prices change monthly and specifications vary by model, so treat an old date as a reason to check before relying on a figure.
Third-party links
Links to manufacturer specifications, labelling programmes and statistical publications lead to content we do not control.
Intellectual property
Manufacturer and product names are used for identification. All original text and calculations on this site are our own.
Liability
This site provides calculations, not energy advice. We are not responsible for purchasing or usage decisions made based on what you read here.
Changes
We may update these terms; the date above reflects the last change.
