Have you ever thought of trading in your old smartphone?
Recycling your phone is a great way to help the environment and earn some extra money, and Clove Technology offers a recycling programme that pays you for your old phone(s)!
So if you're about to buy a new phone from us, or you've recently bought one, why not sell us the handset you no longer need?
How much will you offer for my phone?
That depends on its age and condition. More recent phones generally have a higher value than old ones, but other factors can affect value. These include if the phone is working or not and its network lock status. Fully working phones with an unlocked network status will command a higher value if they are in good condition.
We pledge to beat the major recycling services operating in the UK on the price they offer for your
How do I get my phone(s) back to you?
On our recycling site SEARCH, for your phone and provide details of its status and condition. We will then offer you a price for your phone. If you choose the option to Sell Now, a recycling pack to you for returning your phone.
Alternatively, you can call our recycling team on 0330 1180686, choosing option 2.
