Why pay £800+ for a new Samsung when last year's flagship does the same job for half the price?

In 2026, refurbished Samsung phones in the UK are the same cameras, same Galaxy AI, same premium build, typically 30–50% cheaper than new.

The catch: seven S-series generations are on sale second-hand, from the S20 to the S25, and the wrong pick could leave you with a phone that no longer gets updates.

Pick right and you get a flagship with years of support left for mid-range money. This guide ranks the refurbished Samsung Galaxy phones worth buying in the UK right now.

The quick answer: the refurbished Samsung S24 is the best all-round buy for most people, the refurbished Samsung S25 is the best premium pick, and the refurbished Galaxy S23 Ultra remains the camera king. On a tighter budget, a refurbished Samsung S21 still does the job and a refurbished Samsung S20 works as a cheap backup.

Here are the best refurbished Samsung phones UK buyers can pick up right now, ranked by who each one suits.

Best premium: Refurbished Samsung S25

If your budget stretches further, the refurbished Samsung S25 is the newest S series phone you can buy second-hand. It runs the Snapdragon 8 Elite the fastest chip in any Samsung phone with improved Galaxy AI, a brighter display and better battery efficiency than the S24.

Refurbished S25 stock is still limited in late 2026, so discounts are smaller than on older models (typically 15–25% off the new price), but you're buying a phone supported until 2032. Choose the S25 refurbished if you keep your phones for three to four years and want the longest possible runway.

Best overall: Refurbished Samsung Galaxy S24

The sweet spot of the entire S series. The refurbished Samsung S24 gives you a 2024 flagship Galaxy AI features, a gorgeous 120Hz AMOLED display and a superb triple camera for roughly half the price of a new S25. One honest note for UK buyers: British S24 units run Samsung's Exynos 2400 chip rather than the Snapdragon version, which means slightly weaker sustained gaming performance, though everyday speed and efficiency are excellent.

The real win is software support Samsung promises updates until 2031, so a refurbished S24 bought in 2026 still has five years of support ahead of it. If you want the most phone for your money, start here.

Best camera: Refurbished Galaxy S23 Ultra

Photographers, this is your pick. The refurbished Galaxy S23 Ultra packs a 200MP main camera, superb zoom and the built-in S Pen, a combination no standard S series model can match. Its Snapdragon 8 Gen 2 chip still handles everything smoothly, and the large 5,000mAh battery was the best in its generation.

Software support runs to 2028, which is plenty for a phone bought in 2026, and refurbished S23 Ultra prices have fallen hard since the S25 and S26 launches making this the cheapest route into Samsung's true flagship experience. When buying, check the S Pen silo and camera lenses closely on refurbished units, as these are the parts most likely to show wear.

Best value: Refurbished Samsung S23

The standard refurbished Samsung S23 is the quiet bargain of this list. You get the same Snapdragon 8 Gen 2 chip as the Ultra and the same update policy running to 2028, in a compact body many people actually prefer for noticeably less money. You give up the 200MP camera and the S Pen, but the 50MP main camera is excellent in its own right and handles night shots impressively.

In late 2026, refurbished S23 prices sit well under £350 in good condition, which is remarkable value for a phone with over two years of updates still to come. The best pick for anyone who wants a proper flagship without paying Ultra money.

Best budget flagship: Refurbished Samsung Galaxy S22

Here's where expectations need managing honestly. The refurbished Samsung Galaxy S22 is the cheapest way into a 120Hz AMOLED flagship with 5G, and it still feels quick for social media, streaming and photography.

But UK models use the Exynos 2200 chip, which runs warmer and less efficiently than the Snapdragon version, and major OS updates are nearly finished with security patches expected until 2027. Buy it as a capable everyday phone for under £250 not as a long-term investment.

Cheapest decent option: Refurbished Samsung S21

The refurbished Samsung S21 only makes sense at the right price under £200 in good condition. It's a slim, light flagship with a lovely 120Hz display and cameras that still impress, but software support has now ended, which means no new Android versions and no further security patches.

For calls, WhatsApp, browsing and social media it's perfectly fine; for mobile banking and work email, the missing security updates are a genuine drawback worth weighing up. A solid second phone, a teenager's first phone, or a stopgap not a daily driver for years.

Ultra-budget: Refurbished Samsung S20 buy with eyes open

The refurbished Samsung S20 is six years old now, and it shows in the ways that matter most: software support ended years ago, and original batteries are well past their prime.

So why include it at all? Because at under £150 it's the cheapest route to a Samsung flagship-grade display and camera ideal as a backup phone, a sat-nav or media device, or a handset for a child. Only buy from a seller that grades honestly, offers a proper warranty and has tested the battery, and go in knowing this is a disposable-price phone rather than a long-term companion.

How to choose the right refurbished Samsung Galaxy phone

When comparing Refurbished Samsung Galaxy models side by side, five things matter more than anything else:

1. Software support left. This is the single biggest factor. An S24 supported until 2031 is a fundamentally better buy than a cheaper phone with updates already finished.

2. Check the chipset. UK variants of the S22 and S24 use Samsung's Exynos chips rather than Snapdragon. They're fine for daily use but run warmer under heavy gaming worth knowing before you buy.

3. Battery health. A quality refurbisher tests every battery expect at least 85% health, and ask what happens if the battery underperforms.

4. Understand condition grades. Pristine, Excellent and Good sound similar but mean different levels of visible wear.
   

5. Warranty and returns. Never buy a refurbished flagship without at least a 12-month warranty and a 14–30 day returns window. This is what separates proper refurbished phones from risky second-hand gambles. Still on the fence? See whether refurbished Samsung phones are worth buying in our detailed breakdown.

What to check before buying refurbished Samsung mobiles in the UK

Before you pay for any refurbished Samsung mobiles, run through this quick checklist: confirm the phone is unlocked and sim-free for all UK networks; check the IMEI isn't blacklisted; verify the condition grade with actual photos where possible; confirm the warranty length in writing; and check the returns policy. Reputable UK sellers publish all of this upfront if a listing is vague about warranty or grading, walk away.

A genuine refurbished phone has been data-wiped, tested across 50+ checkpoints and reset to factory settings, which is precisely what you're paying a small premium over a used phone for.

Where to buy refurbished Samsung phones in the UK

You've got three sensible routes: specialist refurbished retailers, Samsung's own Certified Re-Newed programme, and general marketplaces. Specialists tend to offer the best combination of price, grading transparency and warranty. Here's how the main UK sellers compare:

*On marketplaces the warranty comes from the individual seller, so always check the listing. Details correct as of October 2026 policies change, so verify on the seller's site before buying.

For a £400 flagship, buy from a specialist or the official programme where the warranty is in writing; marketplaces are fine for cheaper backup phones. Browse the full range of refurbished Samsung phones at Mobile Direct to compare models and grades side by side.

Conclusion

For most UK buyers in 2026, the refurbished Samsung S24 is the pick of flagship features, five years of updates left, and a sensible price. The S25 suits long-term keepers, the S23 Ultra suits camera lovers, and the S23, S22, S21 and S20 cover every tighter budget. Whichever you choose, buy from a seller with a written warranty and honest grading, and check the software support left before you pay.
