Before you start using the postal form

If you’re using an older browser, such as 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 cannot save a partly completed form so gather all your information together before you start to fill it in.

Biofuel traders and producers

HMRC will only accept your claim for repayment of duty on biofuels if you’re otherwise unable to set-off the duty against your normal liability. You can do this on form HO10 (for deferment traders) by contacting the Excise helpline or on form HO930 (for biofuels producers).
