About WattCosts
Last updated 30 October 2026
WattCosts answers one question for UK households: what does this appliance cost to run? Every page gives you the number at today's Ofgem price cap and a calculator to change it for your own tariff and hours.
Who runs this site
WattCosts is owned and built by Owais Farooq, a software developer based in Pakistan. I write the calculators, gather the power ratings and keep every price up to date. I do not work for an energy supplier, a retailer or an appliance brand, and no company pays to be featured or to change a figure.
I am not in the UK, so nothing here depends on my own bills. Every number comes from a source you can check yourself: the price from Ofgem, the power rating from the manufacturer. Each page links to both.
Why it exists
When energy prices change, people search for what their heater, dryer or electric blanket costs to run. Many of the answers they find were written with a price from two or three years ago, use one rough wattage for every model, or bury the figure under several hundred words.
WattCosts does the opposite. The answer comes first, the calculator sits right under it, and all prices come from one file that changes the day Ofgem announces a new cap. Today that price is 26.32p per kWh for 1 October to 31 December 2026.
How the figures are checked
- Prices: the Ofgem price cap for electricity, Direct Debit average for England, Scotland and Wales.
- Power ratings: the manufacturer's spec sheet, manual or product page, linked on each model page. If I cannot find a reliable source for a model, I do not publish a page for it.
- Writing: drafts are prepared with the help of AI writing tools. I check every figure against its source and test every calculator before a page goes live.

Spotted a mistake?
If a wattage, price or calculation looks wrong, email hello@wattcosts.co.uk with the page and what you found. I correct confirmed errors as soon as I can and note the change on the page.
How the site is funded
WattCosts is free to use. It may show advertising, which pays for hosting and the time spent keeping figures current. Adverts never change what a page says about an appliance.
