Black Friday 2026 falls on Friday 27 November, 26 days from today, with Cyber Monday on 30 November, and a small business does not have to take part. If you sell products, a real offer with a real end date is usually worth doing; if you run a takeaway, a salon or a trade, a discount that weekend is usually money given away. Below is the data by business type, the law in one table, the alternatives and a dated plan from Friday 13 November.
When is Black Friday 2026 in the UK, and how long does the interest last?
Black Friday is the day after US Thanksgiving, which the US Office of Personnel Management lists as Thursday 26 November 2026. Which? confirms that "Black Friday is on Friday 27 November 2026", that the weekend "runs from 27 November until Cyber Monday, on 30 November", and that many retailers now discount "from the beginning of the month", so deals are already running.
On Google Trends for the UK, the week containing Black Friday has been the busiest week for "black friday" in each of the last five years, scoring 100, 87, 88, 69 and 77 from 2021 to 2025, against 58 to 65 in the week before and 13 to 18 in the week after (relative figures, not volumes; pulled 12 October 2026). Three weeks out, where 1 November sits, it ran between 19 and 30.
Should a small business do Black Friday at all? The data by business type
The IPA's 2026 Christmas Consumer research (Opinium, 2,000 UK adults, 19 to 22 May 2026) found that 22% plan to spend up to half their Christmas budget during Black Friday, up from 16% in 2025 and 14% in 2023. It is uneven, though. Our calculation from the ONS Retail Sales Index (dataset DRSI, release of 18 September 2026, value indices not seasonally adjusted, each month against the 2025 monthly average at 100) puts internet sales (series KP5W) at 135 in November 2025 and 129 in December, non-food stores (EAFT) at 121 and 129, and small retail businesses across all retailing (J5AJ) at 112 and 108. Online sellers front-load into November; small retailers barely do.
The BRC-KPMG monitor recorded December 2025 total sales up 1.2% and non-food down 0.3%, which Helen Dickinson called "a drab Christmas for retailers", and its February 2026 release said "Many shoppers had held off Christmas spending and waited for the January sales". A November discount does not create demand; it moves it, sometimes away from your December margin.
By business type:
- Shops and online sellers: usually yes, on a few lines, with a real end date.
- Takeaways and restaurants: no. In our 12-month Trends pull of 12 October 2026, "takeaway near me" showed no movement in Black Friday week; use the week for party pre-orders instead.
- Salons: vouchers with a bonus, not a crossed-out price. The "hairdresser near me" line on the same pull is flat through November.
- Trades: sit it out. Nobody plans a boiler failure around a sale.
- Fitness and wellness: pre-sell January. The IPA found 27% plan to use the Boxing Day and January sales; sell January start dates now.
What must a Black Friday offer satisfy legally? The short version
Nothing stops you discounting; the rules are about what you can prove. The consumer provisions of the Digital Markets, Competition and Consumers Act 2024 apply to commercial practices "which happen from 6 April 2025 onwards", and the CMA can now decide a breach itself and fine up to 10% of global turnover. The ASA applies the CAP Code to the ads themselves.
| The claim | What the guidance says |
|---|---|
| "Was £40, now £30" | The ASA expects "at least three months of pricing history", with the higher price charged "for a longer duration than the promotional price" |
| "Ends midnight Monday" | "Promotional offers should not normally be extended beyond their closing dates"; falsely stating that a product is only available for a limited time is a banned practice |
| "Only 12 left" | Materially inaccurate information about availability is banned; the ASA wants a "reasonable estimate of demand" and says "'subject to availability' might not be enough" |
| "Up to 50% off" | The ASA expects "a significant proportion of the items included in the sale" to carry that saving |
| The small print | "All significant terms and conditions should be made clear within the initial piece of marketing material" |
A countdown timer is "not inherently problematic", but the ASA says it is "unacceptable to then keep the discount running" once it reaches zero. And GOV.UK is plain that "Customers have exactly the same rights to refunds when they buy items in a sale as when they buy them at full price". The full version is in our Christmas and Black Friday pricing rules post. None of this is legal advice; it is what the guidance says.
What are the alternatives: bundles, voucher bonuses, free local delivery, "shop small"?
If you cannot show three months at the higher price, do not invent a "was" price.
- A bundle. Three items at their normal combined price with a fourth added. Nothing to prove, a bigger average order.
- A voucher bonus. Buy a £50 gift voucher, receive a £10 voucher valid in January. A salon in Gravesend might sell these to clients already in the chair that week.
- Free local delivery or click and collect over a minimum spend, for the weekend only: a real saving with an honest end date.
- "We are not doing Black Friday." A short, calm post saying why, pointing people to Small Business Saturday on 5 December, a full week later this year. In Medway, Rochester Christmas Market opens on Friday 27 November, so the weekend brings footfall either way.
What is the two-week plan from Friday 13 November to Cyber Monday?
- Friday 13 November. Choose one of the three options and write the offer in one sentence: what, how much, which lines, start, end, conditions. Check the pricing history behind any "was" price.
- Monday 16 November. Build the offer page with the conditions on it. Set any discount code to expire at 23:59 on Monday 30 November. Count stock and write down your estimate of demand.
- Wednesday 18 November. Tell existing customers first: one email saying what is coming and when.
- Friday 20 November. Finish the ad creative and social posts. Schedule any Google seasonality adjustment for the four days only.
- Monday 23 to Thursday 26 November. Warm the audience. In Triple Whale's data from over 33,000 shops (country mix not stated), ad spend in the four days before Black Friday 2025 was "65% of the amount spent during the four-day BFCM weekend".
- Friday 27 November. Offer live from early morning. Email two.
- Saturday 28 to Monday 30 November. One reminder post a day, stock checked against the estimate, and a final email on Monday saying "ends tonight" only because it does. Codes off at 23:59.
- Tuesday 1 December. Page updated, codes dead, prices back. Keep a note of what was charged and when.
How do the Black Friday email and the ads fit together?
Email does the selling; ads do the reminding. You can email existing customers without fresh consent only under the conditions in PECR regulation 22(3): you obtained their details in the course of a sale or negotiations for a sale, the marketing is for your similar products and services only, and they were given a simple means of refusing when their details were collected and in every message since.
Keep subject lines plain and true: "Our Black Friday offer, Friday to Monday only"; "Free local delivery this weekend"; "Ends tonight at midnight".
The conversion campaigns should already be running; the dated budgets are in our seasonal ad strategy for Q4 2026, and our Google Ads versus Facebook Ads comparison covers platform choice. Google's seasonality adjustments are "ideal for short events" of one to seven days and "may not work as well" over more than 14, so set one for Friday 27 to Monday 30 November and nothing longer.
What about Cyber Monday, Small Business Saturday and the week after?
Cyber Monday is the online close of the same offer, not a second offer. On the same five-year pull, the Trends line for "black friday" fell to between 13 and 18 in the week after Black Friday each year from 2021 to 2025, so an offer that runs into December is talking to nobody. Small Business Saturday on 5 December is the second moment for a shop and the only one if you sat Black Friday out.
What do you do on 1 December with the people who bought?
Send a thank-you, not another offer, and ask for a review if you ask every customer. Honour returns: GOV.UK sets out the 14-day cancellation and refund rules for online orders. Then keep November's buyers on the list for January: the IPA's 27% who plan to shop the January sales include some of them.
If you would rather not do this yourself
Most of this is a decision, a page, three emails and a calendar. If you would rather have someone check the pricing history, build the page and run the four-day ad push, that is what our ecommerce marketing and performance marketing services cover, and we will say so if sitting it out is the better call.
