Three Solid iPhones. One Budget. Here's How to Choose.
Refurbished iPhone prices have fallen into a clear pecking order in 2026. The iPhone 13, 14 and 15 are all sitting under — or right at the edge of — that £400 ceiling most UK buyers actually work to, and all three run iOS 27. The question isn't whether they're good phones. They are. The question is which one gives you the best return on whatever you're spending.
Prices shift with stock and condition grade, but the broad market picture is consistent: the iPhone 13 sits at the budget end, the 14 in the middle, and the 15 pushes toward or past £400 depending on grade and storage. Here's what each one actually delivers.
The Specs That Actually Matter for This Decision
The iPhone 13 launched in September 2021 running Apple's A15 Bionic chip. The iPhone 14, which arrived in September 2022, was one of Apple's most controversial launches — it kept the same A15 chip rather than moving up, making it the first time in over a decade Apple hadn't upgraded the processor in a new flagship iPhone. That shared chip means both phones perform virtually identically in everyday tasks.
The iPhone 15, launched in September 2023, stepped up to the A16 Bionic. It also introduced a 48MP main camera (up from 12MP on the 13 and 14), the Dynamic Island notch replacement, and — crucially for anyone with modern accessories — a switch from Lightning to USB-C.
Three meaningful upgrades across two generations. Whether they justify the price gap is the whole argument.
Is the iPhone 13 still worth buying refurbished in 2026?
Yes — with one condition: you need to buy it knowing what generation you're in. The A15 chip is still genuinely quick for everything from banking apps to streaming, and the camera produces excellent shots in decent light. The honest limitation is software longevity. The iPhone 13 is on iOS 27 now, but it's a generation older than the 14 and two behind the 15. Apple typically supports each iPhone for around five to six years of major updates, and the 13 launched in 2021 — you're closer to the end of that runway than the beginning. If you plan to keep a phone for four-plus years, factor that in.
For a two-to-three year horizon, though, the 13 is still a sound buy — particularly at the lower end of the refurbished price range, where the value gap between it and the 14 can make the decision easy.
What is the best refurbished iPhone under £400 in the UK?
For most buyers, it's the iPhone 14 — and the reasons are more nuanced than just "it's newer." The 14 adds Apple's Photonic Engine to its camera system, which meaningfully improves low-light performance across all lenses. It also gains sensor-shift optical image stabilisation on the main camera, a feature previously reserved for the 13 Pro. Crash Detection and Emergency SOS via satellite are genuinely useful safety additions. None of these features are flashy, but they add up.
The catch is that the 13 and 14 share the same chip, the same 6.1-inch 60Hz OLED panel, and produce near-identical shots in good light. If you're comparing them side by side in normal daylight, you'd struggle to tell the photos apart. The 14 earns its slightly higher price in the edge cases — low light, video stability, safety features — not in everyday use.
How Long Will Each Phone Last? The iOS 27 Picture
This is where the buying decision gets concrete. iOS 27 — confirmed at WWDC 2026 in June — supports every iPhone from the iPhone 11 onwards, meaning the 13, 14 and 15 all receive it. No models were dropped this year. That's the good news.
The nuance is in the features. iOS 27's headline addition is a rebuilt, conversational Siri powered by Apple Intelligence. The iPhone 13 and 14 will receive iOS 27 but won't get Apple Intelligence at all — that requires an A17 Pro chip or better, which means iPhone 15 Pro or later. Even the standard iPhone 15 misses out on Apple Intelligence features. So if AI-powered Siri matters to you, none of these three models deliver it.
For everyone else — the vast majority of users who want a phone that runs smoothly, receives security patches, and supports apps for the next few years — all three models remain viable. The iPhone 14 gets you one extra year of update headroom over the 13, and the 15 adds another year beyond that. In pure software-support terms, the 15 wins. Whether that extra year is worth the price premium is a personal call.
How long will a refurbished iPhone 14 last before it stops getting updates?
Based on Apple's historical support pattern of around five to six years per model, and the fact that the iPhone 14 launched in autumn 2022, you're likely looking at major iOS support through to around 2027 or 2028. That's two to three more major iOS releases. Security patches often continue a year or so beyond that. If you buy a refurbished 14 today and keep it for three years, it will almost certainly still be receiving updates when you're ready to move on.
Where the iPhone 15 Makes Sense Under £400
The 15 is a different phone in ways the 13-to-14 step wasn't. The 48MP sensor is a real camera upgrade — more detail in zoomed shots through sensor cropping, noticeably better low-light performance. USB-C replaces Lightning, which matters if your home is already full of USB-C cables for laptops, tablets and earbuds. The Dynamic Island replaces the notch with interactive notifications. And the A16 chip adds a meaningful performance buffer for the years ahead.
The issue is price. In the current refurbished market, a Grade A iPhone 15 128GB tends to start around £380–£440, which either stretches or breaks the £400 ceiling depending on stock and seller. At the lower end of that range, the 15 is excellent value. At the top, you're paying a premium over the 14 for features most users use occasionally, not daily.
If you can find a Grade B (cosmetically worn but fully functional) iPhone 15 within budget, it's worth serious consideration. If the only 15 in budget is a lower-storage 64GB variant — check storage carefully before buying, as 64GB can feel tight quickly.
The Quick Verdict by Buyer Type
- Tightest budget, shortest commitment: Refurbished iPhone 13. Proven chip, solid camera, iOS 27 confirmed. Buy it knowing the update runway is shorter than the other two.
- Best all-round value right now: Refurbished iPhone 14. Better camera in low light, safety features, one extra year of update headroom — at a price that usually clears £400 with room to spare.
- Future-proofing and USB-C matter to you: Stretch for the refurbished iPhone 15 if you can find one at or under £400. It's a more complete upgrade and the USB-C switch alone is worth it if you're keeping the phone three-plus years.
One Thing Worth Checking Before You Buy Anywhere
Whatever model you land on, condition grading is the detail that turns a good price into a good purchase — or a disappointment. Battery health matters especially on iPhones; a cheap Grade C phone with 78% battery health will feel sluggish within a year. Check the grading criteria before you commit, and make sure the retailer is transparent about what their grades actually mean. At Tech4Cash, every device is verified with PhoneCheck before it goes on sale — you can see exactly how we grade refurbished devices and what each condition level means in practice.
