You should apply for approval if you pay the rebated rate of Excise Duty on oil used to fuel a power plant that treats or makes hydrocarbon oil. To apply, you can either:
- use the online form service (sign in to, or set up a Government Gateway account)
- fill in the form on-screen, print and post it to HM Revenue and Customs
- print the postal form, fill in by hand and post to HM Revenue and Customs
Before you start using the postal forms
If you’re 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 gather all your information together before you start to fill it in.
