Travel expenses recharged from supplier

We use a company to provide audit services to our business which can sometimes include travel costs relating to the audit. These costs are itemised on a VAT invoice from the company. Is it a requirement for the supplier to provide us with receipts relating to the travel costs they are charging on the invoice?

Hi.
They would only need to itemise these recharges on a VAT invoice to you.
You wouldn't need to request travel cost receipts from them.
Thankyou.
