There is no deadline or specific date to submit a nomination; the Honours and Appointments Secretariat welcomes applications 365 days a year. However, do bear in mind that the process involves a consideration period of at least 12-18 months. Within that time it can be advisable to send an update letter to keep the Cabinet Office abreast with any new accomplishments.
A National honour can be awarded for all types of achievements and there are usually two categories of people who receive them – charitable, giving people who have given up their time to help others on a local, national or international level, and those who are considered leaders in their chosen field.
