To vary your license, download the Application to Vary a Firearm Certificate and return it to the Firearms Licensing team explaining your 'good reason' for the request.
For example, if you wish to add another firearm to your license, you must be able to justify why you want to do this.
You must advise us of any changes of address or security as soon as practicable.
Complete the Notification of Change of Address form and return to the Firearms Licensing team, along with your current certificate.
