The form to nominate a person for a national Honour is straight forward. You can even do it online. Simply go to www.gov.uk/honours for both the form, and help to complete it.
Once a nomination form is received, extensive checks must take place. So please be patient. It can take 12 to 18 months for these to be completed.
Please do remember that you cannot let the person know that they are being nominated – this is very important.
