Black Friday 2026 UK: The Dates, and How to Tell a Real Deal
Black Friday 2026 is Friday 27 November, Cyber Monday 30 November. How to check a deal is real using price history, unit prices and your refund rights.
Black Friday 2026 is Friday 27 November, and Cyber Monday is Monday 30 November. In practice the sales start well before that, with many retailers running “early Black Friday” offers through November. The hard part isn’t finding a discount; it’s knowing whether the discount is real.
We log the prices of thousands of products on this site every day, and have done since early September. That gives us a baseline to compare against when the Black Friday banners go up. Here’s how to use the same idea yourself.
Ignore the "was" price and look at what the product has actually cost over the last few weeks. Compare cost per unit, not pack price. Check the pack size hasn't changed. Buy what you'd buy anyway, and know your 14-day right to cancel online orders.
Why a big percentage isn’t proof
A “50% off” sticker compares today’s price with a reference price, and that reference is where deals get inflated. UK pricing guidance says a “was” price should be a genuine previous selling price, not one set for a short time to make a discount look bigger. The consumer group Which? has repeatedly found that many products advertised as Black Friday deals were the same price or cheaper at other points in the year.
The fix is simple: ignore the reference price and look at what the product actually cost over the previous weeks.
How we check a deal
Every product page on this site shows the live price, and our discounts page lists products where Amazon itself is showing a discount, with the price refreshed when the page loads. Because we’ve logged daily prices since early September, we can see whether a Black Friday price is genuinely lower than what the product has been selling for, or just back to its usual level after a rise.
You can do a lighter version yourself:
- Note the price now. Bookmark the products you want and jot down today’s price.
- Check again on the day. If the “deal” price is the same as your October note, it isn’t a deal.
- Compare cost per unit. For anything sold in packs, divide by the number of items or the weight. A bigger pack at a smaller discount can still be the better buy.
- Check the pack size. A product can be relisted in a smaller size at a similar price, which raises the cost per unit even with a discount badge.
What tends to be worth waiting for
Retailers tend to concentrate their headline offers on electronics and branded gifts, such as consoles and accessories, headphones and fragrance, because those are the products that bring shoppers in. If you’re planning a present, our guides to Switch 2 accessories, K-beauty bestsellers and the Owala vs Stanley bottles tell you which version to buy before the sale starts, so you’re not deciding under a countdown timer. For Valentine’s, our gift guide has ideas that are worth buying early if the price drops.
Know your rights
- 14 days to cancel. For most online purchases from UK retailers, the Consumer Contracts Regulations give you 14 days after delivery to cancel, with exceptions such as personalised items and sealed hygiene products once opened.
- Faulty goods. Under the Consumer Rights Act, goods must be as described and of satisfactory quality, whether or not they were on offer.
- Christmas returns. Retailers often extend their returns window for purchases made in November and December. Check the policy before you rely on it.
The one rule that saves the most money
Make your list before the sales start. Black Friday works on urgency: countdown timers, limited stock and lightning deals are all there to make you decide fast. A deal on something you didn’t need is still money spent.
