It’s no secret: Apple iPhones aren’t cheap. And with Apple warning it can no longer shield customers from future price hikes, they could soon become even more expensive. Fortunately, there’s a simple way to save hundreds of pounds, and that’s with buying a refurbished iPhone instead of a brand-new one.Professionally cleaned, tested and restored to a near-new condition, refurbished iPhones deliver the same iOS experience for much less. Better still, unlike buying a used phone from Facebook Marketplace or eBay, they undergo rigorous quality checks and typically come with a charging cable and a one-year warranty.Condition varies between retailers, but even handsets graded as “fair” are fully functional and come with at least 80 per cent battery health. Below, I’ve rounded up the best refurbished iPhone deals from trusted retailers, including savings on refurbished iPhone 17 and iPhone 17 Pro models (prices correct at the time of writing).Back Market refurbished iPhone deals: Backmarket.co.uk(Back Market)Launched in 2014, Back Market is a UK marketplace for refurbished devices. It partners with trusted refurbishers in the UK who clean, test and certify the iPhone’s quality before it is sold, ensuring each device’s battery has at least 85 per cent of its original capacity. That’s better than the majority of the retailers on this list, who set the bar at 80 per cent battery health.Back Market categorises its refurbished iPhones into four grades. There’s excellent (like-new), good (light signs of wear) and fair (signs of wear with no impact on performance). It’s also recently introduced a premium grade. Phones with a premium grade have no signs of use and have been refurbished using genuine manufacturer parts, as well as boasting a minimum battery capacity of 90 per cent. Back Market’s iPhones have up to 60 per cent off, compared with buying the handsets new, and each device comes with a minimum 12-month warranty.Prices are always changing but, at the time of writing, we can see iPhone 17 Pro handsets in excellent condition (usually £1,099, now £931, Backmarket.co.uk), excellent iPhone 16 Pro handsets (usually £999, now £600, Backmarket.co.uk), iPhone 15 Pro Max in good condition (usually £1,199, now £487, Backmarket.co.uk), iPhone 14 Pro Max in good condition (usually £1,199, now £369, Backmarket.co.uk), iPhone 13 deals in good condition (usually £599, now £250, Backmarket.co.uk), as well as slightly older devices.

A battery health test is completed, with MusicMagpie replacing it if it falls below a certain threshold, and each handset comes with a year’s warranty.

As well as selling brand-new handsets and carrier contract deals, Mobiles.co.uk also sells refurbished iPhones on its website.According to the company, most of its refurbished handsets aren’t used phones but “change of mind” returns or, in rare circumstances, due to a manufacturer's fault, which are fixed before the devices are re-sold. All of the handsets have a 12-month warranty, and if your purchase develops a fault in the first month, the retailer will swap it for a replacement. Currys will also fix your iPhone if it develops a fault after the first month.However, it’s worth pointing out that Mobiles.co.uk’s refurbished iPhone deals work a little differently from most retailers.

Unlike buying a used iPhone from an individual seller, refurbished models undergo rigorous quality checks before being resold and typically come with a warranty. The main differences are cosmetic, with lower-graded models showing more signs of wear but costing less. Most reputable refurbishers also guarantee at least 80 per cent battery health, which is Apple's recommended minimum for peak performance.Is buying a refurbished iPhone worth it?If you're on a budget, a refurbished iPhone is one of the best ways to save money. New iPhones practically never receive a discount, especially in the months after launch, Refurbished models can cost hundreds of pounds less and still get you the same features and software experience. Trusted refurbishers also come with several checks for peace of mind. What is the difference between used and refurbished?A used iPhone is typically one that’s been sold by its previous owner on eBay or Facebook Marketplace, with no guarantee over its condition, battery health or functionality. A refurbished iPhone, on the other hand, has been professionally tested, cleaned and repaired before being resold and comes with a warranty. It’s also been checked to ensure everything works as expected.Do refurbished iPhones last long?A refurbished iPhone should last just as long as a new iPhone, provided it's been refurbished by a reputable retailer. Apple supports iPhones with software updates for many years, so even old iPhones continue to receive new features and security updates. We’d recommend choosing an iPhone with at least 80 per cent battery health – the higher the battery health percentage, the longer it will last. Looking for a new smartphone?
