Second-hand or refurbished tech shops offer a sustainable alternative to buying new, keeping old gadgets out of landfill, as well as helping to save money on your next purchase.
In our first-ever second-hand tech retailer survey, we asked 2,495 people to share their experiences of buying pre-loved smartphones, laptops, tablets and smartwatches from 18 shops.
We were pleasantly surprised by the results – 10 retailers received a customer score of 80% or more. And of these, at least 90% of respondents said they’d recommend them. That means you’re spoilt for choice on places to find bargains – particularly worth knowing if you’ve been wary of buying pre-owned tech.
Read on to find out which four retailers met our criteria to be crowned Which? Recommended Providers for second-hand tech.

Four retailers are WRPs for second-hand tech: Samsung Certified Re-Newed, The iOutlet, Dell and Envirophone.
With a customer score of 83%, it's one of the highest-scoring shops, and the best choice if you’re after Samsung tech.
Samsung Certified Re-Newed got four and five stars across all the areas we looked at.
Products are inspected by experts, fitted with genuine Samsung parts, and repackaged. No wonder customers gave it a full five stars for product quality. Several told us you wouldn’t be able to tell the products were refurbished, with one saying: 'You wouldn't believe it was second-hand,' while another described it as 'masterful work'. Another customer praised the 'very fast' delivery. An impressive 97% of respondents said they would recommend it.
Samsung Certified Re-Newed stock does sell out, and new batches are typically added between October and November.
The iOutlet is one of only two shops in our survey to get five stars for customer service (the other being Samsung). One customer called the customer service ‘top-notch’, and another said: ‘They were so helpful, courteous, easy to communicate with on the phone as well via email.’
The iOutlet primarily sells Apple products, but also stocks Google and Samsung phones, as well as some game consoles and PCs. Devices get a 70+ point diagnostic check, and phones come with a battery of at least 75% of the original capacity.
Customers liked the quality of the products and the accuracy of the product description, with one happy shopper telling us that the device they bought 'looked and performed like new, despite being refurbished'. It also got five stars for value for money.
If you're looking to buy a Dell laptop, desktop or monitor, it’s worth checking out the refurbished devices available from the brand itself.
Shoppers loved the range and availability of products, and told us that the quality of the products was good, too. One person said that they'd checked the built-in diagnostics on the laptop they bought, and it had been used for less than 10 hours but had cost 25% less than the lowest price they could find.
Dell was praised by customers for its value for money, which got four stars. One respondent told us that devices are ‘well-discounted’ and another said they got a ‘huge saving’ compared to buying a brand-new device.
Envirofone got four stars across the board, plus five stars for value for money. It focuses on trading-in your tech, but also sells a variety of products including phones, tablets, laptops, wearables and games consoles.
In September 2025, the Envirofone brand was acquired from global IT asset disposal company SK TES by recommerce specialists, including Matt Green, co-founder and director of the iOutlet, and Sam Hargreaves, who launched Technology Recycle Group (later acquired by ReBuy).
Customers in our survey liked the value of devices, with one saying: 'They offer high-quality devices at a fraction of the cost of new ones.' People also liked the 'smooth and reliable' buying process and fast delivery.
The majority of retailers in our survey (apart from Apple, O2, and Samsung Certified Re-Newed) assign a grading to the products they sell based on their condition. This varies from shop to shop, but generally, you’ll find like-new devices graded as ‘Like New’, ‘Premium’ or ‘Excellent’, for example, with products showing more signs of wear graded as ‘Good’ or ‘B’ or ‘F’ grade. Make sure you know the condition of the product you're buying.
