From HM Revenue & Customs · Excise Statutory Interest Manual
Undue delay refers to a situation where a taxpayer makes a claim for repayment or drawback of excise duty, and HMRC fails to authorise it within the allowable period specified in paragraph 4 of schedule 3 to the FA 2001, see ESIM3300.
Undue delay also covers the situation where a taxpayer makes a claim for repayment or drawback of excise duty but HMRC set off the amount against a duty assessment, and that assessment is subsequently withdrawn. This is set out in paragraph 5 of schedule 3 to the FA 2001, see ESIM3700.
