Grade A, My Foot: How to Vet a Refurbished Phone Without Getting Burned
Refurbished phones have gone from car-boot curiosity to mainstream UK purchase. That is good news for your wallet and slightly bad news for your scepticism. The label Grade A is not a regulated standard; it is a shop's opinion. In 2026 you can buy a two-year-old flagship for less than a mid-range new phone, but only if you check the right things before payment.
The grade label is a shop's opinion, not a law of physics
One retailer's Grade A means flawless. Another's means tiny marks you need a torch to see. A third means the screen was replaced with a decent aftermarket panel and the battery is tired. None of that is illegal, but you need to know which version you are buying. Ask for photos of the actual handset, not stock images, and ask what Grade A means in that shop's own words.
1. Battery health: ask for a screenshot, not a promise
Battery is the first thing to age and the easiest thing to fudge. On an iPhone, go to Settings > Battery > Battery Health & Charging and look at Maximum Capacity. On Android the route varies; some phones show design capacity in a service menu, while others need an app like AccuBattery to estimate after a few cycles. For a phone that is two years old, 85% or above is reasonable. Below 80% and you should price in a replacement, which is often £50 to £90 fitted. Ask whether the battery is genuine and whether the phone shows any non-genuine battery warning. A vague line about battery tested is not the same as a health figure.
2. IMEI: run it before you fall in love
Ask for the IMEI before you pay. Dial *#06# on the handset and check it matches the listing, the box and the settings. Run it through a basic free checker and, for a UK purchase, consider a paid check such as CheckMEND that covers network blacklists and insurance claims. Confirm the phone is not activation locked: iCloud Activation Lock on iPhone or Google FRP on Android. A seller who will not share an IMEI is not being shy; they are giving you an answer. If you can meet in person, put your own SIM in and make a call before money changes hands.
3. Warranty wording: the exclusions are the product
A 12-month warranty sounds reassuring until you read that it excludes the battery, the screen and water damage. Check who honours it: the retailer, the refurbisher or a third-party insurer. In the UK, your statutory rights sit against the trader, and a warranty does not replace them. Goods must be as described, of satisfactory quality and fit for purpose. Still, a warranty makes life easier if it covers the parts that fail. Ask how long the battery is covered, who pays return postage, whether they repair or replace, and how long a repair takes. Get the answers in writing before you buy.
4. Return window: know your escape route
Buying online usually gives you a 14-day cancellation window under the Consumer Contracts Regulations, but check the seller's own policy too. Some offer 30 days; some charge a restocking fee; some exclude change of mind. When the phone arrives, test it properly within the window: calls, Wi-Fi, Bluetooth, cameras front and back, charging, speakers, microphone, buttons, Face ID or fingerprint, and the screen across the whole surface. Keep the packaging. If something is wrong, report it in writing immediately rather than waiting for the warranty to become relevant.
5. Screen and repair tells: look closely, then look again
A replaced screen is not automatically bad, but a cheap one can be. On an iPhone, check whether True Tone is available in Settings > Display & Brightness; its absence can hint at a non-genuine display. Test auto-brightness, the proximity sensor during a call and Face ID. Look for uneven gaps around the frame, adhesive residue, dust under the glass, colour shift at an angle and dead spots when you drag an icon around. On Android, test the under-display fingerprint reader and check whether the refresh rate feels right. A repaired phone may have lost its water resistance, so do not test that with a tap. Ask directly whether the screen has been replaced and with what.
A five-minute pre-payment script
Ask for the actual photos, a battery health screenshot, the IMEI, the warranty terms and the return policy. If the seller dodges any of those, walk. Pay by credit card where you can, or by a method with buyer protection. A bank transfer to a stranger is a gift, not a purchase.
The bottom line
A good refurbished phone is transparent, not mysterious. The grade label is a starting point, but the battery figure, IMEI check, warranty wording, return window and screen inspection are what actually protect your money. Do those five things and the refurb gamble becomes a fairly sensible bet.
