Some manufacturers such as Dell also offer to take back any old equipment when you need to dispose of it:-
In some circumstances I may also offer to take away any old computer equipment for you, this is then repaired/refurbished and given away to local charities and good causes
IMPORTANT:
Make sure your hard disk has been removed and destroyed or securely wiped before disposing of your PC - failure to do this could mean someone else could get access to your files, passwords and other sensitive information.
Either remove the drive from the computer as per images below and completely destroy / smash the drive with a hammer, or I can securely wipe and dispose of any hard drives for you if required, the cost of this service is £10 per drive and a certificate will be provided for each drive to confirm they have been securely wiped.
N.B. This includes disposing of the hard drive NOT disposing of the whole computer
The first two example images below show the location and appearance of a hard disk in both a desktop and a laptop computer
And this example image shows location of a NVMe style drive in a Dell laptop
