Quick answer

Many UK Boxing Day sales open online before the day they are named after: John Lewis opened its 2025 sale online at 5pm on Christmas Eve. No retailer has confirmed 2026 dates. Shop opening is a separate question, and each chain decides for itself, so check your branch before you travel. The start time is the easy half: what settles it is whether the price beats November.

What tells you a price is real, in ninety seconds

By 26 December the year's heaviest tech discounting is a month behind you, and most of what appears on a post-Christmas sale page has been through it. That changes the question: not "is this cheap", but "is this cheaper than it was four weeks ago".

Your November note is the benchmark, not the struck-through figure

If you wrote down what a model sold for over the Black Friday weekend, you hold the one number no retailer can rewrite. A December price above the November price for the same model is not a deeper cut, it is the November discount back with new signage.

Pull a twelve-month price history for the exact model number as well, before you look at the offer, from a price tracker or browser add-on that keeps a record of listed prices over time. Your November note settles whether December beats November; it cannot tell you whether November itself was a low, and often it was not. The note is the figure to beat, the twelve-month chart is the figure to aim at. A chart reaching back only three months is useless here: it holds the November event and little else to compare with.

The ninety second check

  • Search the exact model number, including any suffix letters. A model carried by one retailer with no independent coverage anywhere gives you nothing to compare against, and a price-match desk cannot help either.
  • Read two things off the price chart. The lowest figure the model has held, and when. Set your walk-away number from that, and ignore the banner percentage.
  • Check the sold-by line at checkout, not on the product page. A marketplace listing can look identical while routing returns and warranty elsewhere.
  • Put your own postcode in before you commit. Showing a headline price and then adding mandatory charges as you move through checkout is what the Competition and Markets Authority calls drip pricing, prohibited under the unfair commercial practices provisions of the Digital Markets, Competition and Consumers Act 2024, in force since 6 April 2025. The carve-out is not about delivery specifically. Where the nature of the product means part of the price genuinely cannot be worked out in advance, the retailer has to show how that part is calculated, in enough detail for you to reach the total yourself, and as prominently as the part it can state. Once you have given it your postcode the charge is calculable, and from that point every price you are shown has to include it. So enter the postcode yourself and surface the total before you decide.

What a struck-through price is allowed to be

A reference price must be a real previous selling price, but how much selling counts is not settled law. On 30 July 2026 the High Court declined to endorse the CMA's proposed one-to-two sales volume ratio in the Emma Matratzen case and asked both sides to agree an order without it. Our guide to the November event has the detail. The practical position on the day: the "was" figure is a claim you cannot verify from the page, so do not let it set your number.

What is actually on the page after Christmas

Boxing Day stock is residue plus gift overstock, and two things follow. The categories that clear hardest are the ones that overbought for Christmas, not the ones you want, and the model you researched in November may not be listed at all. Our view: with a researched shortlist November is the better event, this the fallback. Buying whatever happens to be reduced, the day is fine, but you still need a number: pull the twelve-month chart on your phone before you pay, not after.

Where the date earns its keep is the follow-on purchase, the thing that arrived on Christmas Day and needs something else to be useful. A smart lighting kit that wants a fitting the house does not have is the standing example, which is why our look at bayonet-fitting smart bulbs is mostly about the fitting and the router. A television whose dialogue is a mumble is the other, and a small soundbar aimed at speech clarity is a cheaper answer than replacing the set.

The calendar, from late November to mid January

Retailers do not announce start times in advance, and none has confirmed a 2026 date as things stand. What follows is the shape the season has taken and what to do in each phase. Last year's pattern does not bind this year.

Late November: the event you are asking about has already happened

Black Friday 2026 is Friday 27 November and Cyber Monday is Monday 30 November. The deepest tech discounting of the year sits there, and our Black Friday timing guide covers the run-up. One job here whether or not you buy: write the November figure down against every model on your shortlist. Thirty seconds per model is why December becomes readable.

The first three weeks of December: one thing to act on

Prices drift back up after Cyber Monday and the constraint becomes logistics rather than price. If something has to arrive before Christmas, buy against the retailer's own guaranteed cut-off rather than a courier's general one. One thing does need doing here. If you bought in November and might want to cancel and rebuy in the sale, that window ends fourteen days after the day the goods reached you, so for most Black Friday deliveries it falls somewhere in mid December. Work the date out now and diarise it, because it will almost certainly have passed by Boxing Day, and read the exclusions below before you count on it at all.

23 to 25 December: the sale starts before the day it is named after

The recent pattern has been online first. In 2025 both John Lewis and Marks and Spencer ran their post-Christmas reductions online, with almost every M&S shop shut on the day, outlets and a handful of convenience stores aside, and every John Lewis branch bar Stratford and the Trafford Centre closed until the 27th. John Lewis published its own times: the sale opened online at 5pm on Christmas Eve, with in-store trading starting nationwide on the 27th. Treat 24 December as the point to start watching, and do not read an early launch as evidence of depth: it tells you about a marketing calendar, not a price.

Saturday 26 December: the day itself

Boxing Day 2026 falls on a Saturday, and gov.uk lists the bank holiday for it as a substitute day on Monday 28 December in England and Wales, in Scotland and in Northern Ireland. So the 26th is an ordinary Saturday for shop opening: no Sunday restrictions, and each retailer sets its own hours. Open is not automatic. Marks and Spencer kept nearly all its shops shut on Boxing Day 2025, trading only outlets and a small number of convenience stores, and John Lewis opened only Stratford and the Trafford Centre, so check your specific branch's hours on the retailer's own site before you set off.

One trade-off to weigh before you go. Buying in a shop rather than online gives up the fourteen day cancellation right entirely: gov.uk states a business does not have to refund a customer who no longer wants an item unless they bought it without seeing it. Faulty goods are unaffected and a credit card still gives you section 75, but if there is any chance you will change your mind, order it online from the same retailer instead.

On when to go, there is evidence rather than instinct. MRI Software put footfall across UK retail destinations on Boxing Day 2025 up 4.4 per cent year on year, its strongest year-on-year increase in more than a decade, with the 5pm to 11pm window averaging 9.6 per cent up against 3.1 per cent from 6am to 5pm. Two caveats: that rise followed a Boxing Day 2024 down 4.9 per cent, and footfall is not price. Those two window figures are year-on-year changes, not headcounts: the evening grew faster than the daytime, which is not the same as the evening being busier. Nothing here tells you which hour is quietest, so go early for stock, not on an assumption about queues.

Sunday 27 December: the shortest shopping day of the week

In England and Wales, shops over 280 square metres may open for only six continuous hours between 10am and 6pm on a Sunday, under Schedule 1 of the Sunday Trading Act 1994. Scotland has no equivalent restriction, and in Northern Ireland large shops may open between 1pm and 6pm under Article 5 of the Shops (Sunday Trading etc.) (Northern Ireland) Order 1997. If your plan needs you in a branch, this is the narrow day.

Monday 28 December: the substitute bank holiday

Shops open. Post does not. Royal Mail does not deliver or collect on UK bank holidays, and it does not collect on Boxing Day itself, so an order placed on Saturday the 26th is not collected until Tuesday 29 December and realistically lands on the Wednesday. Couriers run their own bank holiday schedules, so check the retailer's. Those are mainland assumptions. On Royal Mail's guaranteed next-day service most Highlands postcodes still get the next working day, just by 5.30pm rather than 1pm, while the far north and the offshore islands move to two or three working days. Northern Ireland is not on that list at all. What does bite there is the retailers and marketplace sellers, who add a surcharge or drop those postcodes from free and next-day options, a practice the Advertising Standards Authority has issued an enforcement notice about. If that is you, add days to the Tuesday rather than counting on it, and check the delivery page before you pay.

Late December into January: the clearance proper

Discounting keeps running into the first week of January at most retailers, longer on homeware and furniture. What changes is the stock, not the depth: January leans towards outgoing models, so the usual outcome by mid month is a better price on last season's version, not on the one you wanted.

Running the decision in order

Most of this happens before 26 December, which is why so few people do it. None of it applies if what you need has already stopped working: buy the cheapest model that clears your specification and stop reading.

  1. Decide the list in November. Three candidate models per purchase, full model numbers, ranked. Fitting out a whole room instead of swapping one item, settle the list first: our home office desk kit guide shows the shape that list takes. Working out the requirement mid-sale is how bundles win.
  2. Record the November price against each one, then set a walk-away figure from the twelve-month low. Not from the discount percentage, and not from the reference price. Every later step depends on this one.
  3. If you bought in November, fix your cancellation deadline now. Fourteen days after the day the goods came into your hands: delivered 1 December, your last day is 15 December; delivered 12 December, it is 26 December. Decide on that date, not on Boxing Day. Check the exclusions below first: genuinely bespoke goods are outside the right altogether, and sealed software, audio or video loses it once you break the seal. Setting a device up does not end the right, though the retailer can cut the refund for handling beyond what a shop would have allowed.
  4. Start watching on 24 December. Establish whether your models are listed at all. If one clears your number on Christmas Eve, take it: there is no prize for waiting until the 26th.
  5. Before you pay, check three things. The model number matches exactly. Buying online, the sold-by line is the retailer and not a marketplace seller, and the total at checkout with your postcode entered still clears your number. Buying in a branch, neither of those checks exists: read the shelf-edge price against your number, and remember you are giving up the cancellation period.
  6. Pay by credit card where the item qualifies. Under section 75 of the Consumer Credit Act 1974 the card provider is jointly and severally liable with the retailer for breach of contract or misrepresentation, meaning you can pursue the card provider for the whole claim, on a cash price over 100 pounds and not more than 30,000 pounds. The weeks after Christmas are when retailers fail. Section 75 does not reach a debit card or cash. The fallback there is chargeback, which is a card scheme rule rather than a legal right: Visa states that it is not a legal right and that a refund is not guaranteed, only that participating card providers follow an agreed set of rules, and that a claim usually has to be made within 120 days of the purchase. Ask your bank early rather than waiting to find out whether the administrators pay anything out.
  7. Diarise the end of your cancellation period the day it arrives. Fourteen days from the day after delivery, on an online order only, under the Consumer Contracts Regulations 2013, subject to the exclusions below. If you bought it in a shop there is no such period and this step does not apply to you.
  8. If it arrives faulty, act inside thirty days. Section 22 of the Consumer Rights Act 2015 gives thirty days from delivery to reject faulty goods for a full refund, and that clock does not care that the item was reduced.

Where this goes wrong, and how to get your money back

Six failures account for most of the money lost in this window.

  • Cancelling a November order to rebuy in the sale, and finding the window shut. Under regulation 30 of the Consumer Contracts Regulations 2013, the cancellation period for goods ends fourteen days after the day they come into your physical possession. A Black Friday order delivered on 1 December can still be cancelled up to the end of 15 December and is out of time from 16 December, ten days before Boxing Day. For the right to still be alive on the 26th, the goods must have reached you on or after 12 December. Check the delivery date first: for most November purchases the answer is no.
  • Assuming the cancellation right covers what you bought. Three exclusions cover a lot of tech, and apply whether or not the window is open. Bought in a shop there is no change-of-mind right at all: gov.uk states a business does not have to refund a customer who no longer wants an item unless they bought it without seeing it. Sealed audio, sealed video and sealed software lose the right once unsealed, and goods made to the consumer's specification or clearly personalised are excluded outright, both under regulation 28. Do not assume a configured PC is caught by that: the government's implementing guidance on the regulations names a computer among the things that can be assembled after your order from parts offered in a standard range, which it says is not bespoke, so a machine you specced from a retailer's dropdown menus normally keeps the cancellation right. Ask for a finish or a part the retailer does not otherwise offer and it can tip the other way, and the guidance says these are judged case by case. Regulation 34 also lets a trader cut the refund for loss in value from handling beyond what a shop would allow. The tactic pays on a sealed, unused, online order from the retailer itself. On anything you have set up and signed into the right usually survives, but the deduction for handling can eat the saving, which is what makes it not worth doing. Two costs come with the tactic even when it works. Under regulation 35 the direct cost of sending the goods back is yours unless the retailer agreed to cover it or never told you it fell to you, and on anything large that can swallow the price drop you were chasing. And where you paid by buy now pay later, the money does not come straight back to you. Citizens Advice says you have to tell the provider yourself so it can stop further payments being taken. Klarna pauses the instalments as soon as you report the return in its app, but only the store can adjust what you actually owe, and if the store never registers it your original payments still apply. So report it the day you send it back, chase the store, and treat a replacement on the same scheme as its own separate plan.
  • Treating an extended Christmas returns window as a legal right. It is not one. Citizens Advice puts it plainly: shops need not take back a non-faulty item you have changed your mind about, and the fourteen or thirty day policies they advertise are goodwill. A generous-looking December window can still demand the item unused, unopened and back by a fixed January date. Read it the day you buy.
  • Trying to return a gift you did not pay for. Citizens Advice notes that only the buyer can claim under a warranty or guarantee, unless the wording covers third party rights. A gift receipt is the retailer choosing to hand the return over, not a legal transfer. If a present is faulty rather than unwanted, ask the buyer for the receipt and let their rights do the work. Time this the day you open it. The buyer's rights run from when the goods reached the buyer, not from when you unwrapped them, so the thirty day window for rejecting a faulty item outright can be nearly spent by Boxing Day: a gift delivered on Black Friday weekend has days rather than weeks left on 25 December. Say something on Christmas Day, not in January.
  • Buying discounted hardware whose real cost is a subscription. Common in the categories that clear after Christmas: cameras, doorbells, trackers, anything with an app. The sale price covers the hardware, the plan is the product, so price the first year rather than the box. Our review of a doorbell that records to a memory card covers what skipping the plan costs you.
  • A delivery date that slides. With Sunday the 27th and a bank holiday on the 28th, the Royal Mail week effectively restarts on Tuesday 29 December. If what you are buying has a date attached, a birthday, a return-by date on the retailer's own Christmas policy, or a room you want finished before you go back to work, count back from Tuesday 29 December rather than from the day you order.

Frequently asked questions

What time do the Boxing Day sales start?

There is no fixed time, and no UK retailer has published a 2026 schedule yet. Recent years have followed one shape: the reductions appear online first, from Christmas Eve, while shop opening is decided chain by chain and some stay shut on the day. Start watching from the 24th rather than setting an alarm for the 26th, and check your own branch's hours before you travel.

Are Boxing Day prices better than Black Friday?

Not reliably on a specific model, because the two events are stocked differently. Boxing Day is largely a clearance of what did not sell in November plus what was overbought for Christmas, so the depth follows the retailer's surplus, not your shortlist. Note November prices and you can settle this for your own list in seconds.

Can I return a Christmas present I do not want?

Only if the shop's own policy allows it. Citizens Advice is clear there is no automatic right to your money back on a non-faulty item you simply changed your mind about. An online order does carry a fourteen day cancellation right, but it belongs to whoever placed the order and runs from delivery, so a present bought in November is usually out of time by Boxing Day. If it is faulty rather than unwanted, tell the buyer straight away. Their thirty day right to reject runs from the day it was delivered to them, so a November purchase can be almost out of time by Boxing Day. The fourteen day online cancellation right also does not survive unsealing software or media, does not apply to genuinely bespoke goods, and is not available at all on anything bought in a shop.

Will the bank holiday hold up my delivery?

Yes, by a day. Monday 28 December 2026 is the substitute Boxing Day bank holiday listed on gov.uk, and Royal Mail does not deliver or collect on bank holidays, so the Monday lands on top of a Sunday that is outside its standard service anyway. Royal Mail does not collect on Boxing Day itself either, so an order placed on the 26th is not collected until Tuesday 29 December and realistically arrives on the Wednesday, though couriers set their own schedules.

What if the price drops again after I bought it?

Use the retailer's own price promise first if it has one, and read its dates the day you buy, not the day you want to claim. Failing that, an online order can be cancelled up to the end of fourteen days after the day it was delivered, under the Consumer Contracts Regulations 2013, but that route does not exist for anything bought in a shop, does not survive unsealing software or media, does not apply to genuinely bespoke goods, and the refund can be cut back for wear that goes beyond the handling a shop would allow. A PC configured from a retailer's standard options is not usually bespoke, so it normally keeps the right.
