Terms of use

Last updated 30 October 2026

By using WattCosts you agree to these terms. They are short because the site is simple: free calculators and information, with no account to create.

Using the site

You may use the calculators and read the pages for your own personal, non-commercial purposes. You may link to any page. Please do not copy large parts of the site, scrape it automatically, or present our pages as your own.

Estimates, not guarantees

Running costs on this site are estimates based on published prices and manufacturer power ratings. Your actual cost depends on your tariff, region, the exact model and how you use it. See the disclaimer and how we calculate.

Content and trademarks

The text, calculators and design of WattCosts belong to Owais Farooq. Brand and model names are the property of their owners and are used only to identify the appliance a page is about. WattCosts is not connected to, sponsored or endorsed by any appliance brand, retailer or energy supplier.

Links to other websites

We link to sources such as Ofgem and manufacturers so you can check our figures. We are not responsible for the content of those sites.

Availability

We aim to keep the site available and accurate, but we may change, pause or remove pages at any time without notice.

Liability

We are not liable for any loss arising from decisions made using estimates on this site, to the extent the law allows. Nothing in these terms limits any rights you have under the law where you live that cannot be excluded.

Changes

We may update these terms. The date at the top shows the latest version. Questions: hello@wattcosts.co.uk.
