VATREG21950 | Voluntary registration: how to establish entitlement to register as an intending trader: introduction
From HM Revenue & Customs · VAT Registration
Before you can allow registration as an intending trader, you must be satisfied that there is a business in existence which has a firm intention to make taxable supplies. However, the trader does not have to:
state the date by which he expects to begin making taxable supplies, or
estimate the value of them.
