You can use any packaging as long as it’s secure and you may want to put a note inside with your account number and a list of equipment that is included. The link provided by @MightyQuinn explains about how to receive an email with your return labels through Royal Mail.
Keep your proof of posting safe and indefinitely and if you use Royal Mail’s collect from home service, keep a record of the tracking number.
