How to Dispose of Old Computers and Phones Safely
Safely wipe, recycle, sell or donate old computers and phones in the UK: back up, sign out, erase data properly and find responsible disposal routes.
That old laptop in the cupboard and the phone in the kitchen drawer still hold your photos, passwords and emails. Throwing them away, or handing them on, without properly clearing them is how personal data ends up in the wrong hands. Doing it right takes less than an hour.
Step 1: Back up what you want to keep
Copy photos, documents and anything else you need to your new device, an external drive or cloud storage. Confirm the files open there before you erase anything. See how to back up your computer and transferring data to a new computer.
Step 2: Sign out and unlink
Before wiping, remove the device from your accounts:
- Sign out of your device account and any find-my-device features, which can otherwise lock the device for the next owner.
- Deactivate software licences and cloud services.
- Unpair Bluetooth devices, smartwatches and similar.
- Remove the SIM card and any memory cards.
- Disable two-factor authentication apps only after confirming you have moved them to the new phone.
Step 3: Erase the data properly
Phones and tablets
Use the "erase all content and settings" or factory reset option. Modern phones encrypt storage by default, so a reset renders the data unreadable. Make sure the device is signed out of your account first.
Windows and Mac computers
Use the system's reset option and choose to remove everything, including files. For computers that have an SSD with encryption turned on, this is generally effective. If the device holds very sensitive information, consider extra measures such as using the secure-erase tools offered by the drive maker.
Old hard drives
A simple delete or quick format is not enough. Use a full wipe tool, or physically destroy the drive if it contains highly sensitive data and the machine is not being reused. Drives that are dead can still contain data and should be treated the same way.
Step 4: Choose where it goes
| Option | Good for | Watch out for |
|---|---|---|
| Selling or giving away | Working devices | Wipe thoroughly, remove accounts |
| Trade-in schemes | Newer phones and laptops | Check what happens to data |
| Retailer take-back | Convenient recycling | Confirm they accept your item |
| Council recycling centre | Broken electronics | Never put in household bins |
| Charity reuse schemes | Working devices | Ask about their data erasure |
| Local repair or refurbish shops | Reuse and repair | Ask how they handle data |
Electrical items should not go in general household waste in the UK, and batteries in particular are a fire risk. If a battery is swollen, handle it with care. See laptop battery replacement.
Step 5: Check before you hand it over
- Does it start up at the setup screen with no accounts?
- Are there stickers with passwords or notes on the casing?
- Have you removed any cables, adapters or cards you want to keep?
- Is the drive truly erased, and have you removed it if you are unsure?
Special cases
Work devices
Do not wipe or dispose of a work device yourself. Return it through your employer's process, and make sure a business device handling customer data is disposed of securely, as outlined in the small business IT basics checklist.
Smart home gadgets
Cameras, speakers and doorbells store account links and sometimes footage. Remove them from your account and reset them before passing on.
Devices you are unsure about
If you are nervous about wiping, a technician can do it and give you peace of mind. On Compito you can search by postcode, compare ID-verified local providers and send a request listing the devices. You receive an offer to accept and pay online and can message the provider to confirm what will happen to each item. See tech support services.
A worked example: clearing out a drawer
Someone finds a five-year-old laptop, two old phones and a tablet. They sort them into three piles. First, devices worth selling or giving away, which get backed up, signed out and reset. Second, devices that no longer turn on, which go to a recycling point after the owner removes the SIM and memory cards. Third, the laptop's drive, which holds tax records, so it is taken out and kept safely until it can be wiped fully or destroyed. The whole job takes an afternoon, and nothing personal leaves the house.
What can be recovered from a device you thought was wiped
- Deleted files that were never overwritten, on older mechanical drives.
- Saved passwords and logged-in sessions in browsers.
- Photos and messages still stored in app caches.
- Email and cloud accounts still signed in on the device.
- Account links that let the next owner see your name or contact details.
A proper reset with encryption on, and signing out of every account, deals with nearly all of this for modern devices.
Common mistakes
- Factory resetting while still signed in to a cloud account, which can lock the device for a buyer.
- Selling a laptop with the old drive still inside, and the data still on it.
- Forgetting memory cards, SIM cards and USB sticks tucked inside cases.
- Leaving a smartwatch paired to the phone you are selling.
- Putting electronics in household bins.
Selling online: sensible habits
- Do the reset before you advertise, and photograph the setup screen as proof.
- Meet in a public place or use tracked postage.
- Be wary of buyers who overpay and ask you to return the difference.
- Hand it over only when payment has actually arrived in your account.
If the device is shared or not yours
Family tablets, hand-me-downs and work devices raise ownership questions. Check who set up the accounts, and whether another family member needs files or photos first. For anything issued by an employer, follow their process rather than wiping it yourself.
Less confident users
If you are helping an older relative, make a short list of each device, what is on it and what should be kept, before touching anything. Never rush a reset because a helpful stranger or caller offered to do it for you.
Frequently asked questions
Is a factory reset enough before selling a phone?
For modern phones, yes, provided you sign out of your accounts first and the phone is encrypted, which is the default on current devices.
Can I just remove the hard drive and bin the laptop?
You can dispose of the rest through recycling routes, but keep or destroy the drive properly. The laptop itself still should go to electrical recycling.
Should I worry about data on a broken device?
Yes, a device that does not work can still hold readable data. Treat broken drives and phones with the same care.
