Short answer: What you pay for a refurbished Galaxy S23 in the UK depends on the model, storage and condition grade – the standard S23 is the cheapest of the three, the S23+ sits in the middle and the S23 Ultra costs the most, while Like New costs the most, then Excellent, then Very Good, and Fair is the cheapest. At The Tech Gadgets, every unit is unlocked and SIM-free, backed by a 12-month warranty and 30-day UK returns – use the links in the table below to check today's price for each model and storage option. If a listing you find elsewhere is priced far below the rest of the market for the same storage and grade, treat it as a red flag rather than a bargain. Below is a table linking to today's price for every model and storage option, what actually moves the price up or down, and an honest read on whether 2026 is still a sensible time to buy a refurbished Galaxy S23.
This guide is deliberately focused on one question: how much should you pay, right now, for a refurbished Galaxy S23, S23+ or S23 Ultra in the UK, and where can you actually buy one at a fair price? If you want the full spec-by-spec breakdown of the three models – display sizes, camera systems, battery capacities and which one suits which type of user – that's covered in depth in our separate Refurbished Samsung Galaxy S23 Series UK guide. Here, the focus stays squarely on price, deal-spotting and buying decisions: what a cheap Galaxy S23 unlocked actually looks like, where to buy refurbished Galaxy S23 stock in the UK, and how to tell a genuine deal from an underpriced red flag.

Stock is subject to change – always check the live product page for today's price and stock before ordering. All four condition grades are currently listed on every Galaxy S23, S23+ and S23 Ultra product page at The Tech Gadgets: Like New, Excellent, Very Good and Fair – Like New costs the most, then Excellent, then Very Good, and Fair is the cheapest. If you specifically want a lower grade at a lower price, check the variant selector on the product page for live stock in that grade, or contact The Tech Gadgets directly, since refurbished inventory turns over quickly.
What Affects the Price of a Refurbished Galaxy S23
If you're trying to work out whether a price you've been quoted – here or anywhere else – is reasonable, four things move the number more than anything else.
1. Condition Grade
The Tech Gadgets grades refurbished stock as Like New, Excellent, Very Good or Fair. In general, a lower cosmetic grade should mean a lower price, since you're trading a bit of visible wear (light marks, minor scuffs) for a cheaper unit that is still fully functionally tested. The exact cosmetic criteria that separate each grade – for example, how many marks are allowed on the screen versus the back glass – are not published on the product pages, so if grade condition matters a lot to you, it's worth confirming with The Tech Gadgets directly before ordering. As noted above, all four grades are currently listed across all three S23-family listings, so grade-based savings are there to compare on this range – check the product page for live stock in the grade you want.
2. Storage Tier
Storage is the most predictable price driver. Across all three S23 models in our range, each step up in storage adds to the price – check today's price for each option using the product links in the table above:
- Galaxy S23: 128GB → 256GB → 512GB
- Galaxy S23+: 128GB → 256GB → 512GB
- Galaxy S23 Ultra: 256GB → 512GB → 1TB
If you're not a heavy photo, video or 4K-recording user, 128GB or 256GB is plenty for most people and is the cheapest way into any of the three models. The 1TB Ultra makes sense mainly if you shoot a lot of the S23 Ultra's 200MP photos or 8K video and don't want to rely on cloud storage.
3. Model – S23 vs S23+ vs S23 Ultra
The single biggest jump in price is choosing between the three models, since it reflects real hardware differences, not just refurbishment logic. The standard S23 is the cheapest and smallest; the S23 Ultra is the most expensive because it adds a built-in S Pen, a 200MP main camera and dual telephoto lenses (3x and 10x optical zoom) that the S23 and S23+ don't have. If you don't specifically want the S Pen or the extra zoom, the S23+ gets you a larger 6.6-inch screen and bigger battery for considerably less than the Ultra. For the full spec-by-spec breakdown of all three models – display sizes, cameras, batteries and who each one suits – see our Refurbished Samsung Galaxy S23 Series UK guide; this article focuses purely on pricing and deal-hunting.
4. Colour Demand
All colours of a given model and storage tier are priced identically in our range (for example, Phantom Black, Cream, Graphite, Green, Lavender and Lime Galaxy S23 128GB units in the same grade are all the same price). In the wider secondhand and refurbished market, however, more popular colours (typically black and cream/white tones) tend to sell through faster and can occasionally command a small premium on resale-style marketplaces, while less common colours can sometimes be found slightly cheaper simply because they move slower. If you're not fussy about colour, picking whichever shade is in stock is usually the most efficient way to buy.
Refurbished vs New vs Contract – What Should You Actually Pay?
To judge whether a refurbished Galaxy S23 price is genuinely good, it helps to know what the phone cost when new. At UK launch in February 2023, Samsung's recommended retail prices were:
- Galaxy S23: £849 (128GB) / £899 (256GB)
- Galaxy S23+: £1,049 (256GB) / £1,149 (512GB)
- Galaxy S23 Ultra: £1,249 (256GB) / £1,399 (512GB) / £1,599 (1TB)
Measured against those original RRPs, The Tech Gadgets' refurbished prices are noticeably cheaper than the launch price for every model and storage tier – check today's price on each product page to see the current difference. That's the honest way to frame it: these are 2023 launch prices, not what Samsung charges today, since the Galaxy S23 has since been superseded by the S24 and S25 series and is largely no longer sold new by Samsung UK. Refurbished is now, in practice, the main route to owning an S23-generation phone at all, new-in-box stock having largely dried up.
For a market-rate sanity check, you can compare listings on UK refurbished marketplaces such as Back Market – note that their headline "from" prices typically reflect the lowest available condition grade and smallest storage, and vary by seller, condition and exact configuration, so they aren't directly comparable to The Tech Gadgets' Like New pricing without matching grade and storage. As a rule of thumb, if you see a Galaxy S23 advertised far below the rest of the market in genuinely good cosmetic condition with a proper warranty, check carefully what grade and warranty length is actually being offered before assuming it's a like-for-like deal.
Compared with buying on a mobile contract, refurbished is almost always cheaper over the life of the device. A new flagship on a 24-month UK contract typically works out to £30–£45 a month once you include the device cost, which is £720–£1,080 over two years before you even own the phone outright. Buying a refurbished Galaxy S23 outright and pairing it with a SIM-only plan (commonly £8–£15 a month for a generous data allowance in the UK) is usually the cheaper route unless you specifically need the very latest chip or camera generation.
How to Get the Best Deal on a Refurbished Galaxy S23
Finding a genuinely good refurbished Galaxy S23 price in the UK isn't just about hunting for the lowest headline number – it's about matching price to grade, storage and warranty so you know exactly what you're getting. A few practical pointers:
- Match grade to price, not just the number. Two Galaxy S23 listings at different prices aren't the same deal if one is a lower cosmetic grade with less warranty cover. Always check what condition grade a price actually refers to before comparing it to another listing.
- Buy the storage you'll actually use. Since storage is one of the biggest levers on price across the S23 range, don't pay for 512GB or 1TB "just in case" if you typically use cloud storage and stay well under 128GB today.
- Go SIM-free and pick your own plan. Every Galaxy S23 sold by The Tech Gadgets is unlocked and SIM-free, so you're free to shop separately for the cheapest SIM-only deal rather than being locked into a bundled contract price that hides the true cost of the handset.
- Consider a lower grade if price is your top priority. All four grades – Like New, Excellent, Very Good and Fair – are currently listed across the S23 range at The Tech Gadgets. If a cheaper Excellent, Very Good or Fair unit would suit you better, check the product page for live stock in that grade or contact The Tech Gadgets directly, since refurbished stock turns over regularly.
- Factor in the warranty when comparing prices across retailers. A slightly higher price with a full 12-month warranty is usually better value than a slightly lower price with a 30- or 90-day warranty, since screen and battery issues on a refurbished phone are far more likely to surface after the first few weeks than during them.
- Confirm the phone is genuinely unlocked and IMEI-clean before paying. This applies whichever retailer you buy from, not just The Tech Gadgets – ask for confirmation in writing if it isn't stated clearly on the listing.
Is Now a Good Time to Buy a Refurbished Galaxy S23 in 2026?
This deserves an honest answer rather than a sales pitch, because the Galaxy S23 is no longer a new phone.
The Galaxy S23 series launched in February 2023, so by September 2026 the phones are around three and a half years old. Samsung committed to four major Android/One UI upgrades and five years of security updates for the S23 line. Industry reporting through 2026 indicates the S23 series is set to receive One UI 9 (based on Android 17) as its final major OS update, which fulfils that original four-generation commitment; security patches are expected to continue for a while longer under the five-year policy, but the S23 will not get the newer 7-year update commitment Samsung introduced starting with the Galaxy S24. In practical terms, that means: you should expect this to be at or near the end of the phone's major feature-update runway, though it should keep receiving security patches for some time yet – worth confirming Samsung's current published support dates for your specific model before buying if this matters to you.
On raw performance, that ageing update runway is offset by genuinely strong hardware. Every S23-family phone runs the Snapdragon 8 Gen 2 for Galaxy chipset, a customised, higher-clocked version of what was Qualcomm's flagship processor at the time, and it remains a fast, capable chip for everyday use, gaming and photography in 2026 – comfortably ahead of most mid-range phones currently sold new. The 120Hz AMOLED displays, IP68 water resistance and multi-lens cameras (up to 200MP on the Ultra) have also aged well.
One area we won't guess at is battery health. Every Galaxy S23 shipped from Samsung with a 3900mAh (S23), 4700mAh (S23+) or 5000mAh (S23 Ultra) battery, and lithium-ion batteries generally lose some capacity over three-plus years of use and charge cycles. Battery health percentage on the specific unit you'd receive is not specified by The Tech Gadgets on the product pages, and battery wear is explicitly excluded from the 12-month warranty – so if battery longevity is a priority for you, ask The Tech Gadgets to confirm the battery condition of your unit before you order, rather than assuming a like-new battery from the "Like New" cosmetic grade (which describes physical condition, not battery health).
Put together: if you want the lowest possible price for a phone that still feels genuinely fast today, and you're comfortable that major Android version updates are near their end, a refurbished Galaxy S23 at refurbished prices is a reasonable buy in 2026. If having several more years of major OS upgrades ahead of you matters more than price, a refurbished Galaxy S24 or S25 (also available at The Tech Gadgets) will cost more upfront but buys a longer runway. There's no wrong answer here – it depends on whether you prioritise price today or update longevity over the next few years.
Where to Buy a Refurbished Galaxy S23 in the UK
The Tech Gadgets is a Manchester-based UK refurbished electronics retailer selling the Galaxy S23, S23+ and S23 Ultra fully unlocked and SIM-free, with same-day dispatch on orders placed before 3pm Monday to Friday and typical next-working-day UK delivery. Every phone is functionally tested before dispatch and covered by a 12-month warranty (covering manufacturing defects and functional faults; battery wear, physical damage, water damage and electrical/short-circuit damage are excluded) plus 30 days to return it from delivery if you contact us first.
If you're comparing prices before you buy – which we'd always recommend for any purchase this size – it's worth checking listings on other established UK refurbished marketplaces such as Back Market or CeX for the same model, storage and grade, so you're comparing like with like rather than just the headline "from" price. Whichever retailer you buy from, confirm in writing: the exact condition grade, what's included in the box, the warranty length and what it excludes, and the returns window, before you commit.
Network compatibility is one less thing to worry about with any Galaxy S23 model bought SIM-free: all three support 5G, Wi-Fi 6E and Bluetooth 5.3, with both nano-SIM and eSIM support, and work across EE, O2, Vodafone, Three and other UK or international networks without needing an unlock fee. That means you can buy the handset from The Tech Gadgets and separately shop around for whichever SIM-only deal offers the best value at the time, rather than being tied to a single network's pricing.
FAQ
Is a refurbished Galaxy S23 still worth buying in 2026?
For most buyers, yes – it pairs a genuinely fast Snapdragon 8 Gen 2 for Galaxy chipset, a 120Hz AMOLED display and a strong camera system with a price well below its 2023 launch RRP. The main trade-off is that the S23 series is nearing the end of its major Android OS update commitment (One UI 9 is expected as its final major update), so if you want several more years of new Android versions specifically, a newer refurbished model like the S24 or S25 may suit you better. If price and current-day performance matter more than future OS versions, the S23 remains a sound buy.
What's included when I buy a refurbished Galaxy S23?
Every unit is unlocked, SIM-free and functionally tested before dispatch, and comes with a 12-month warranty and 30-day UK returns. Exact box contents (for example, whether a charging cable is included) are not confirmed on the product pages at the time of writing – check with The Tech Gadgets before ordering if this matters to you. For the Galaxy S23 Ultra specifically, whether the S Pen is included with a given unit is also not confirmed on the page and should be checked before you buy.
What's the difference between Like New, Excellent, Very Good and Fair grades?
These are the four condition grades The Tech Gadgets uses across its refurbished range, generally running from minimal visible wear (Like New) down to more noticeable but still fully functional cosmetic wear (Fair). The precise inspection criteria that separate each grade are not published on the product pages, so if the exact cosmetic condition matters to you, contact The Tech Gadgets directly to confirm before ordering. All four grades are currently listed across the S23, S23+ and S23 Ultra listings – check the product page for live stock in the grade you want.
How much should I pay for a refurbished Galaxy S23 Ultra?
The price of a refurbished Galaxy S23 Ultra depends on storage (256GB, 512GB or 1TB) and condition grade – Like New costs the most, then Excellent, then Very Good, and Fair is the cheapest. Check today's price on the Galaxy S23 Ultra product page. Headline "from" prices on broader UK refurbished marketplaces typically reflect a lower grade and/or smaller storage than 256GB Like New, so always compare like-for-like grade and storage rather than just the lowest advertised number.
Is it safe to buy a refurbished phone online in the UK?
Yes, as long as you buy from a retailer that clearly states the condition grade, offers a genuine warranty (not just a returns window), confirms the phone is unlocked and IMEI-clean, and gives you a proper UK returns period. The Tech Gadgets offers a 12-month warranty and 30-day returns on every refurbished Galaxy S23 sold, alongside SIM-free unlocking for use on any UK network. As with any purchase, if a price looks dramatically below the rest of the market for the same grade and storage, treat that as a reason to ask more questions rather than a reason to buy faster.
