A refurbished iPhone is one of the smartest ways to buy Apple in 2026. You get the same phone for a lot less, you keep a working device out of landfill, and from the right seller you get a warranty and support that a second-hand marketplace listing can never match. The catch is that the word refurbished is not regulated, so quality varies enormously depending on who you buy from.
This guide explains everything you need to know before you buy, from what the grades actually mean to how battery health, warranty and returns work. Everything below reflects how we do things at The iOutlet, so you can use it as a checklist for us or for anyone else you are considering.
Is a refurbished iPhone worth it?
For most people, yes. A good refurbished iPhone works exactly like a new one, costs far less, and comes with the safety net of a warranty. Prices in our own range start from under £100 for older models and climb to the newest handsets, so there is a refurbished iPhone for almost every budget. A refurbished iPhone 11, for example, still handles everything most people need for a fraction of its original price.
The saving is only worth it if the phone is genuinely sound, though. That is where grades, battery health and testing come in, and why buying from a seller who is clear about all three matters so much.
Understanding refurbished grades
A grade describes the cosmetic condition of a phone, not how well it works. Every device we sell is fully tested and in good working order regardless of grade. The grade simply tells you how it looks, and a lower grade is an easy way to pay less for a phone that performs identically. Our full guide to refurbished grades goes into more detail, but here is the short version.
| Grade | Condition | What to expect |
|---|---|---|
| A+ Pristine | Like new | No visible signs of wear. Looks and feels brand new, ideal as a gift. |
| A Excellent | Minimal wear | Light scratches or scuffs only. Excellent condition for the money. |
| B Good | Moderate wear | Some marks across the device, fully tested and in good working order. The best value if you use a case. |
| C Average | Heavy wear | Noticeable scratches or scuffs, fully functional. The cheapest way in if looks matter less than function. |
Our advice for most buyers is simple. If you use a case and a screen protector, a Grade B phone is the one to go for, since the marks it has will largely be hidden and you pay noticeably less than for Grade A. If the phone is a gift or you like to use it without a case, step up to Grade A or A+.
Battery health, and why it matters most
Battery is the part of a used iPhone that wears fastest, so it is the single most important thing to check. An iPhone battery is measured by its maximum capacity, shown as a percentage of when it was new. A phone at 100 percent holds a full charge, while one at 80 percent holds a bit less and will need charging more often.
Every refurbished iPhone we sell is guaranteed to have a battery at a minimum of 75 percent health, and you can choose to upgrade to a brand new battery if you want maximum life from day one. That is the kind of guarantee worth looking for. A marketplace seller rarely tells you the battery figure at all. Once your phone arrives, it is worth knowing how to check your iPhone’s battery health yourself so you know exactly what you have.
Warranty and returns
This is what separates a refurbished iPhone from a gamble. Every iPhone we sell comes with a free 12-month warranty, so if something goes wrong through no fault of your own, you are covered. On top of that, you have 30 days to return the phone for a change of mind or if it is faulty, and after that window a faulty device will be repaired or replaced under warranty.
Before you buy from anyone, check two things. First, how long the warranty lasts and what it covers. Second, how returns work and how long you have. If a seller offers no warranty or a vague one, treat the low price as the risk it is. You can read the full detail of how ours works on our returns information page.
How a phone should be tested before it is sold
A proper refurbisher does far more than wipe a phone and put it back on sale. Every device we sell goes through a multi-stage inspection and a 70-plus point check covering the screen, battery, cameras, buttons, speakers, Face ID or Touch ID, and everything else that needs to work.
Just as important, every unit is Phonecheck tested. That cross references the phone’s IMEI number against police, network provider and insurance databases to confirm it has not been reported lost, stolen or subject to an insurance claim. It is also why every phone we sell is unlocked and contract-free, so it will work on any UK network out of the box. If a seller cannot tell you a phone has been checked this way, that is a reason to walk away.
What to check before you buy a refurbished iPhone
Run through these before you hand over any money, whether you are buying from us or anyone else.
The grade. Make sure you know the cosmetic grade and what it means, so the phone that arrives matches what you pictured.
Battery health. Look for a guaranteed minimum battery percentage. If a listing does not mention the battery at all, be cautious.
Warranty length. Twelve months is what you should expect. Anything shorter, or no warranty, is a red flag.
Returns window. Check you can send the phone back if you change your mind, and how long you have to do it.
Lost and stolen checks. The phone should have been checked against the relevant databases and be unlocked and contract-free.
iOS support. An older model is only a bargain if it still gets updates. Every iPhone we stock is still supported, and you can check how long each iPhone keeps getting iOS updates before you decide.
Which refurbished iPhone should you buy?
The right model comes down to budget and how long you want the phone to last. At the affordable end, the iPhone SE (2020) and iPhone XR are dependable everyday phones. In the middle, the iPhone 11 and iPhone 12 remain the best value for most people. If you want something that will feel current for years, a refurbished iPhone 13 or newer is the one to aim for.
If you want the newest models, we carry the full range up to the iPhone 17. And if price is the deciding factor, our refurbished iPhones under £100 collection is the cheapest way in. For a fuller breakdown by price, see our guide to the latest iPhone comparisons.
How to save even more
There are three easy ways to bring the price down further. Choose a lower cosmetic grade, since a Grade B phone works exactly like a Grade A one for less. Trade in your old phone and put its value straight towards the new one with an instant quote on our sell my iPhone page. Or spread the cost with Klarna or through our phone leasing options rather than paying upfront.

Frequently asked questions
Are refurbished iPhones reliable?
Yes, as long as you buy from a proper refurbisher. Every iPhone we sell is fully tested through a 70-plus point check, comes with a 12-month warranty, and is guaranteed to have a battery at a minimum of 75 percent health. The risk comes from unchecked marketplace listings, not from refurbished phones as a category.
What does refurbished grade mean?
Grade describes cosmetic condition only, not function. A+ is like new, A has minimal wear, B has moderate wear, and C shows heavier wear. Every grade is fully tested and works the same, so a lower grade is a simple way to pay less.

Look for a guaranteed minimum. Ours are guaranteed at a minimum of 75 percent battery health, with the option to upgrade to a brand new battery for maximum life.
