The Queen, 96 and facing ongoing mobility difficulties, instead opted to watch the ceremony on television as she rests at Windsor Castle.
Among the attendees was the Prime Minister and his wife Carrie. However, as the couple got out of their car and walked up the steps of St Paul's Cathedral some members of the crowd booed them.
Labour leader Sir Keir Starmer, first ministers of the devolved governments and former prime ministers were also in attendance.
Public service is the theme at the heart of the religious event, with 400 people who are recipients of honours, including NHS and key workers who were recognised for their work during the pandemic, invited.
The Archbishop of York will deliver the sermon and has described the prospect as a "slightly terrifying gig".
The Most Rev Stephen Cottrell had to step in at the 11th hour after the Archbishop of Canterbury, the Most Rev Justin Welby, contracted Covid-19.
He said of the Queen: "I am really sad she is not here because I want to say some personal things to her, thanksgiving for what she has given to our nation, but I am sure she will be watching on the telly."
Hundreds of people gathered, some wearing Union flag hats and others hanging flags and bunting over the railings on the approach to the cathedral.
