Donating Old Business Computers? How to Wipe Them and Hand Them Over Properly

A refresh leaves most small businesses with a cupboard of computers that are too slow for the office but perfectly usable for a school, a community group or a family without a laptop. Donating them is generous and keeps hardware out of the waste stream. It also hands a stranger a box of drives that spent years holding client files, payroll and staff email.

Our guide to wiping retired computers covers decommissioning in general. This article is about the donation itself: what to agree with the recipient, how to prepare a batch, and what to hand over so the gift is useful rather than a liability.

Why is my business still responsible after donating a computer?

Under UK GDPR your organisation remains the controller of the personal data on those drives. Giving the hardware away does not transfer the duty to keep that data secure, so it must be removed before the machines leave.

The ICO expects personal data to be protected throughout its life, including when equipment is reused or given away, and it expects you to be able to show what you did. Our guide to UK GDPR and data wiping for small businesses covers the wider obligations.

What should I agree with the charity or school first?

Ask what they actually need, which models they accept, whether they want an operating system installed, and how collection works. Agree that you will wipe before handover and that any wipe they do is an extra layer.

A five-minute conversation saves a lot of rework:

• Do they want complete working machines, blank machines, or only certain parts?
• Is there a minimum specification or age they will accept?
• Do they need chargers, docks or monitors as well?
• Will they collect, or do you deliver?
• Would a list of serial numbers help their own records?

How should I prepare a donation batch?

List every device, move users' files off them, sign them out of your accounts and management tools, then erase each one, record the result and reinstall a clean operating system if the recipient wants one.

1. Make an inventory. Asset tag, serial number, model, storage type and condition. Mark any machine that will not power on.
2. Move the data. Make sure each user's local files, especially Desktop, Downloads and Documents, are on their new device or in shared storage.
3. Release the device. Sign out of email, cloud storage and business apps; remove it from your device management system; release Macs from Apple Business Manager and turn off Find My.
4. Erase the whole of every drive. Use a bootable tool so the installed system and its encryption are no obstacle.
5. Record each result. Serial number, method, date, outcome and the person who did it.
6. Reinstall if agreed. Use official media and stop at the first setup screen.

Should we keep or destroy the drives instead?

Usually not. A machine with an erased drive is far more useful to a charity than an empty chassis. Keep or destroy drives only where policy demands it for high-risk roles, or where a drive has failed and cannot be erased.

If you do remove a drive, label it and send it through your usual destruction route with a record. Never donate a machine with a drive nobody has dealt with.

Is a factory reset good enough for donated computers?

Not for business machines. A reset depends on the options chosen and may leave recovery areas or remnants, it only touches the drive the operating system sees, and it leaves no evidence.

Hard drives should be overwritten in full and SSDs erased with their own sanitise commands, because wear levelling leaves spare areas an overwrite may miss. Our comparison of disk wiping and factory reset explains the gap.

What about software licences on donated PCs?

Check your agreements before including any paid software. Some licences can transfer with the hardware and many cannot, so do not assume business or volume licences travel with a donated machine.

A clean installation of an operating system the recipient can legitimately activate is normally the safest option.

What should go in the box with the computers?

Clean machines with your asset labels removed, chargers and any agreed accessories, and a simple list of serial numbers. Keep the manufacturer's labels in place so the recipient can get support.

What records should we keep?

One line per device: serial number, erasure method, date, result and operator, plus any tool report saved against the asset tag. That record is how you show later that the data was gone before the machines left.

Our article on why audit-ready erasure reports matter explains what a useful report contains.

Which RedKey USB option suits a donation batch?

For a batch of office machines, RedKey USB Professional is the natural fit: it erases each computer from USB, supports up to 16 disks per machine, and saves a PDF report for every erasure. The 5-Pack lets several staff work in parallel.

It works with most Intel and AMD PCs and most Intel-based Macs from 2006 to 2020, and it is a one-time purchase with unlimited use, so next year's refresh costs nothing extra. If phones and tablets are part of the donation, the Ultimate edition adds support for selected Apple and Android devices. A roll of our data wiped stickers gives the recipient a visible sign that each machine has been cleared.

Frequently asked questions

Can the charity wipe the computers for us?

They can add a second layer, but your business stays responsible for the data. Wipe and record each device before it leaves.

Do donated computers need an operating system?

Ask the recipient. Many prefer a clean operating system stopped at the first setup screen; some refurbishers want blank drives.

What if a computer will not turn on?

Remove its drive and erase it in another machine, or send the drive for destruction with a record, before donating the rest.
