Black Friday 2026 falls on Friday 27 November, with Cyber Monday on 30 November, according to Which?. Sales now start well before then, and the loudest banners are not always the best prices. This guide explains what the evidence says about Black Friday deals, what the competition watchdog has just punished, and the checks that take two minutes before you pay. It is general consumer information, not financial advice.
When Black Friday 2026 starts and ends
The main day is 27 November, and Which? describes the wider sales weekend as running until Cyber Monday on 30 November. Many shops begin earlier. PriceSpy notes that Black Friday week deals often start around 21 November, and some shops start earlier still. Because every retailer sets its own dates and terms, check the shop’s own page rather than relying on a roundup that was written weeks ago.
What the evidence says about Black Friday prices
Which? tracked prices for a full year around the 2024 sale, from May 2024 to May 2025, covering 175 home, tech and health products from eight retailers. It found that 83% of products were the same price or cheaper on at least one occasion outside the four-week sales period, and that none of the deals it followed was at its lowest price of the year on Black Friday itself. Which? also stresses that genuine bargains exist but are less common than the marketing suggests.
| Retailer | Share of tracked deals the same price or cheaper at other times |
|---|---|
| John Lewis | 94% |
| Very | 93% |
| Amazon | 88% |
| AO | 85% |
| Argos | 79% |
| Richer Sounds | 55% |
For balance, MoneySavingExpert’s 2025 analysis found that Black Friday prices often beat the run-up to Christmas, so the sales are not a complete washout. The point is that the price you see should be checked, not assumed.
The CMA crackdown on fake urgency
On 14 October 2026 the Competition and Markets Authority announced fines under its new consumer powers. Law firm Lewis Silkin and ITV News report that Wayfair was fined £4.8 million over Daily Deals, 24-hour Flash Deals and countdown timers that implied offers would vanish. Appliances Direct was fined £1.2 million over countdown banners for £10 to £25 discounts, where the same codes reappeared repeatedly, and over automatic opt-ins to paid extras. Gold’s Gym was fined £45,000 for leaving a mandatory joining fee out of the headline price. All three settled, which earned a 40% reduction, according to Lewis Silkin.
The lesson for shoppers is simple. Under the Digital Markets, Competition and Consumers Act 2024, firms can face fines of up to 10% of global turnover, as RPC explains, and a countdown timer must reflect a real deadline. A ticking clock is a sales technique, not proof that a price is special.
Five checks before you buy
- Check the price history. Tools such as PriceSpy, PriceRunner and camelCamelCamel show how a price has moved over months. They are examples, not endorsements.
- Compare at least two other retailers. A discount from an inflated “was” price can still be dearer than a rival’s everyday price.
- Look at the total cost. Add delivery, fees and any extras that were pre-ticked at checkout.
- Check the exact model number. Some products are made specifically for sales events with fewer features than the standard version.
- Set a budget first. A written limit stops impulse buys, and our Christmas budget planner is a simple place to start.
How to spot a scam dressed as a deal
Black Friday is also busy season for fake shops, cloned adverts and delivery texts. Be wary of prices far below every rival, brand-new websites with no contact details, and any request to pay by bank transfer or gift card. Our guide to spotting a fake website before you buy covers the checks in more detail, and how to stop spam calls and texts helps with the follow-up messages. Paying by credit card also matters: Section 75 of the Consumer Credit Act can make your card provider jointly responsible for purchases costing between £100 and £30,000, which is extra protection if a seller disappears.

Your rights if something goes wrong
For most online and phone purchases you have 14 days after delivery to cancel, then a further 14 days to send the goods back, and the seller must refund you within 14 days of getting them. Certain items, such as personalised goods and sealed hygiene products, are exceptions. Separately, the Consumer Rights Act 2015 says goods must be of satisfactory quality, fit for purpose and as described, with a 30-day short-term right to reject faulty items. A shop’s own returns policy may be more generous, so read it before you pay. GOV.UK and Citizens Advice explain each right in plain English.
Frequently asked questions
When is Black Friday 2026 in the UK?
Friday 27 November 2026, with Cyber Monday on Monday 30 November, according to Which?.
Are Black Friday deals really cheaper?
Sometimes. Which? found most tracked products were the same price or cheaper at other times, so check the price history before assuming a deal is genuine.
Are countdown timers allowed?
Only if they reflect a genuine deadline. The CMA fined Wayfair and Appliances Direct in October 2026 over time-limited offers that did not end when they said they would.
Can I get money back if the price drops after I buy?
Only if the retailer runs a price promise or guarantee. Terms differ, so read the small print before you buy.
What is the safest way to pay?
A credit card gives Section 75 protection on purchases from £100 to £30,000, and debit card chargebacks can also help. Avoid bank transfers to unknown sellers.
