Before you start using the postal form
If you are using an older browser, eg Internet Explorer 8, you’ll need to update it or use a different browser. Find out more about browsers.
You’ll need to fill in the form fully before you can print it. You can’t save a partly completed form so we suggest you gather all your information together before you begin to fill it in.
