Black Friday vs Boxing Day: What 175 Product Prices Reveal in the UK

Timing, discounts and category winners compared

Black Friday now extends well beyond a single Friday. Retailers typically open promotions in early November and run through Cyber Monday into what has become known as the “Black Friday period”, with some extending offers into mid-December. Boxing Day, on 26 December, kicks off a second wave that usually continues through the New Year sales into January.

Category matters more than date. Electronics often see their steepest early cuts during Black Friday, when retailers compete hard on big-ticket items like laptops and games consoles. Clothing and seasonal stock behave differently: fashion retailers frequently hold their deepest markdowns for Boxing Day, once they need to clear winter ranges to make room for spring stock.

• Electronics and big-ticket appliances often show their first deep discount in November, though prices can dip again later if stock needs clearing.
• Fashion and seasonal homeware tend to see stronger reductions from 26 December onwards, as retailers clear Christmas and winter ranges.
• Furniture and household goods sit between the two, with some retailers running parallel promotions across both periods.

Online-first shopping has reshaped both events. Many UK retailers now release Black Friday and Boxing Day stock online before in-store availability catches up, which means the best prices and the widest selection often appear on websites first, with physical stores following once online demand settles.

What UK data actually shows about Black Friday and Boxing Day

The headline figures from consumer and government sources tell a more cautious story than retailers’ marketing suggests.

A large majority of products Which? tracked across the Black Friday period were found to be the same price or cheaper at other points in the year, based on analysis of 175 products tracked for a full year against the Black Friday sales window. That matters because it shows a “Black Friday” label is not proof of a genuine low point in an item’s price history.

Official retail figures back this scepticism up. ONS retail sales data shows a detectable “Black Friday effect” on unadjusted monthly sales volumes when the event falls inside the reporting period, but once the figures are seasonally adjusted, the net change is much smaller. In other words, shoppers buy more that week, but the annual pricing pattern barely shifts.

Boxing Day’s pull has also softened. Barclays forecast UK Boxing Day spending at around £3.6 billion for 2025, down from £4.6 billion the year before, according to BBC reporting on Boxing Day sales. Fewer people treating 26 December as a must-shop date means less competitive pressure on retailers to cut prices that day specifically.

• Which? found most tracked Black Friday deals were matched or beaten elsewhere in the year.
• ONS seasonally adjusted figures suggest Black Friday’s effect on genuine annual pricing is modest.
• Barclays and BBC data point to a shrinking Boxing Day spending event.

A five-step checklist for deciding when to buy

Rather than picking a side between Black Friday and Boxing Day, run each purchase through the same routine.

1. Set a maximum acceptable price before you start browsing, based on what the item is worth to you rather than what a discount banner claims.
2. Check the price history using a tracking tool such as PriceRunner, as recommended in Which?'s shopping tips, to see whether the current price is genuinely low.
3. Confirm the retailer’s terms, including delivery charges, warranty length and return windows, since these affect the real cost of the deal.
4. Factor in urgency: if the item must arrive before Christmas, Black Friday and early December give you more buffer than Boxing Day.
5. Decide and set an alert for your target price so you are not relying on memory or willpower to catch the right moment, a method we cover in our guide on setting price alerts.

Some categories have predictable rhythms worth knowing. Televisions often see a second discount cycle in spring, once manufacturers release new models and retailers clear older stock. Fashion rotates with the seasons, so a coat discounted at Boxing Day may dip again during end-of-season clearance in late winter.

Pro Tip: Screenshot the price and product listing whenever you spot a deal; this gives you evidence if you later need to query a price-match claim or request a refund.

Staying safe from misleading urgency and price claims

Countdown timers and “only 2 left” banners are designed to make you act fast, but they are not always accurate. The CMA’s guidance on urgency and price reduction claims warns UK retailers against misleading customers with unverified stock warnings or inflated “was” prices, so treat any claim you cannot verify with scepticism.

A few checks protect both your money and your time:

• Verify the “previous price” against a price-history tool rather than trusting the strikethrough figure on the page.
• Be wary of one-off countdown clocks that reset or reappear on return visits to the same page.
• Avoid sellers who only operate through social media direct messages or unfamiliar domains with no clear returns policy.
• Pay by card where possible, since this gives you access to chargeback protection and, for purchases between £100 and £30,000, Section 75 protection.

Our guide to online shopping safety and Section 75 covers these protections in more detail, including what to do if a purchase goes wrong.

How we help you apply the checklist across both sales

We have a platform that helps simplify this decision by allowing users to filter deals by category and price across the sales calendar in one place.

• Electronics listings allow comparison of prices across retailers before committing to a deal.
• Baby and kids items are grouped together for easier browsing, useful for Christmas gifting.
• Home and garden filters help spot whether a Boxing Day markdown is lower than previous prices.

Used alongside the five-step checklist, this filtering helps simplify the sales calendar into a more manageable shortlist, saving shoppers time.

Our view: plan around a longer, messier sales calendar

Black Friday and Boxing Day have blurred into one long, stretched-out sales season rather than two distinct events. Treat any “limited time” claim as marketing until proven otherwise, and let price history, not the calendar date, decide when you buy. A short checklist beats a hunch every time.

Find your deal without the guesswork

We provide a searchable place to find curated UK discounts across categories like electronics, fashion, and home goods, helping users compare retailers and identify genuine price drops without visiting multiple sites.

Browse our best UK discounts now and set up alerts before the next sales wave hits, whether that is Black Friday, Boxing Day, or the January clearance that follows.

FAQ

Why do we call it Black Friday?

The name originated in the United States, linked to the day after Thanksgiving when retailers historically moved from financial losses (“in the red”) into profit (“in the black”). It has since spread to the UK as a major pre-Christmas shopping event, though it carries no connection to UK retail accounting.

What countries celebrate Boxing Day?

Boxing Day on 26 December is observed as a public holiday and shopping event mainly in the UK, Canada, Australia, New Zealand and several other Commonwealth countries. Its retail significance varies by country, but in the UK it has traditionally marked the start of the post-Christmas sales.

What are the best TV deals for Black Friday?

TV prices often see their first deep cut of the year during the Black Friday period, though Which?'s analysis found many electronics deals were matched or beaten at other points in the year. Checking price history before buying, rather than relying on the Black Friday label, is the most reliable way to confirm a genuine saving.

Is Boxing Day or Black Friday bigger?

By spending forecasts, Black Friday has overtaken Boxing Day in recent years. Barclays forecast UK Boxing Day spending of around £3.6 billion for 2025, down from £4.6 billion in 2024, according to BBC coverage, while Black Friday continues to draw a measurable, if modest, lift in retail sales volumes according to ONS data.
