Question: how long does it take for 1st class signed for?
Answer: Whereas First Class Signed For will provide you with a signature but it is not next day. My understanding, Royal Mail 1st Class Signed For, 90% will arrive with in 3 working days and it is open to consumers. This means, in theory, 1st Class Signed For can be a slower service and you are not able to reclaim VAT.
