"Stamped and signed payslip"

The UKBA guidance says that payslips printed from online must be "stamped and signed" by an employer to be valid evidence of earnings. Does this just mean what it says, ie the company stamp and a squiggle from someone in HR? Or are there other requirements such as a covering letter, employer contact details, etc?

Apologies if this has been covered elsewhere, the threads I found when I searched related to the "evidence from two sources" requirement rather than how to make sure payslips are valid evidence.

Hi,

Just stamp and sign is more than enough. no need of cover letter. but bank statement what you show should match with pay slips.

Thanks

Company Stamp and HR/ Manager's signature is enough

Thanks, appreciate the prompt help!
