Why buy a refurbished iPhone from Zextons?
Buying a refurbished smartphone shouldn't feel like a compromise or a gamble on eBay or Facebook Marketplace. At Zextons we bridge the gap between expensive brand-new retail prices and risky second-hand private sales.
85%+ battery-health floor
We never ship iPhones with degraded batteries. Every handset is tested to ensure optimum capacity and peak-performance support.
100% factory data scrubbed & SIM-free
All devices are legally verified via Blacklist / IMEI checks, wiped clean to GDPR compliance standards, and contract-free — unlocked to all UK networks including O2, EE, Vodafone, Three and giffgaff.
30-day risk-free returns
If you change your mind or want a different model, return your item in its original condition for a hassle-free refund or exchange.
Eco-friendly sustainability
Choosing a pre-owned iPhone diverts electronic waste from landfill and offsets up to 70kg of carbon emissions compared with manufacturing a new phone.
Clean IMEI guarantee
Every handset is checked against the national Blacklist and comes with a clean IMEI, so it's ready to activate on any UK network the moment it arrives.

Biometric security
Verification of Face ID sensor arrays and Touch ID home buttons.

UK refurbished iPhone cosmetic grading system
We grade our iPhones based purely on aesthetic appearance. Every single grade functions 100% like a brand-new phone internally.
| Grade | Aesthetic condition | Screen quality | Ideal for |
|---|---|---|---|
| Pristine | Flawless casing. No visible marks from 20 cm away. | Immaculate, scratch-free glass. | Buyers wanting a brand-new look at a refurbished price. |
| Grade A | Minor, subtle hairline micro-scratches on the casing. | Micro-scratches invisible when the screen is on. | The balance of savings and near-flawless presentation. |
| Grade B | Visible scratches, scuffs or light wear on frame or back glass. | Light surface wear; no cracks or deep gouges. | Maximum cost savings for users using a phone case. |
Refurbished iPhone battery health: what to expect
A common question UK buyers ask is whether a refurbished iPhone needs a 100% battery reading to be reliable.
The 85% standard
Apple considers any battery above 80% maximum capacity to be operating at normal peak performance. At Zextons we guarantee a minimum floor of 85% capacity on our standard range.
Brand-new battery upgrade option
If you prefer a 100% cycle-count battery, select our "New Battery Upgrade" at checkout to have a brand-new battery installed prior to dispatch.
