Hi Stevie and Lek
Re: Nationwide online bank statements - yes, you'll need to print them off and get each page stamped by Nationwide or provide a letter from Nationwide to confirm their authenticity. Here's the most recent guidance on this from the Home Office (Appendix FM-SE updated on 2nd January 2020) - see section A1 para 1 (evidence of Financial Requirements under appendix FM):
1. In relation to evidencing the financial requirements in Appendix FM the following general provisions shall apply:
- (a) Bank statements must:
(i) be from a financial institution regulated by the appropriate regulatory body for the country in which
that institution is operating.
(ii) not be from a financial institution on the list of excluded institutions in Appendix P of these rules.
(iii) in relation to personal bank statements be only in the name of:
(1) the applicant’s partner, the applicant or both as appropriate; or
(2) if the applicant is a child the applicant parent’s partner, the applicant’s parent or both as
(3) if the applicant is an adult dependent relative, the applicant’s sponsor or the applicant, unless
(iv) cover the period(s) specified.
(v) be: (1) on official bank stationery; or
(2) electronic bank statements which are either accompanied by a letter from the bank on its headed
stationery confirming that the documents are authentic or which bear the official stamp of the
issuing bank on every page.
