We've a client who is due a refund of VAT into six figures after we'd taken them on and submitted a 652. In order to speed up the process, the client has been speaking to his main contractor who advised that previously, they'd requested a voluntary VAT visit, they then come out within 10 days and any refund is paid in a further 7 days. This with a £1000 fee paid to HMRC. With submitting a 652, the process could be quite lengthy in obtaining the refund as they're likely to request further info and perhaps a visit however with nothing to hide and eager to receive the amount, he'd be happy with a visit.
Having never come across this or able to find anything online, little confused. Has anyone heard of this?
