Yours Faithfully vs. Yours Sincerely

In traditional UK formal-letter convention, “Yours sincerely” follows a salutation that names the recipient, while “Yours faithfully” follows “Dear Sir or Madam” or another unnamed-recipient salutation. Modern workplaces may use other closings, so audience and house style still matter.

Quick answer

For traditional UK formal letters: use “Yours sincerely” when you know and use the recipient’s name; use “Yours faithfully” after “Dear Sir or Madam.”

Important caveats

Email Boundary

Email often permits less formal closings, so copy the letter convention only when the context actually calls for it.

Other professional closings are common today; the traditional pair is not a universal rule for every country or organization.
