A two-minute silence was held at 11am to honour ex-servicemen and women who gave the ultimate sacrifice for our country.
The Queen will lead tributes in Whitehall, central London, while churches, villages, towns and cities across the UK will conduct their own memorials and parades for those whose lives have been lost.
Remembrance Sunday commemorates those who died in the First and Second World Wars, and also later conflicts such as in Ireland, Bosnia, Iraq and Afghanistan.
It does not aim to make a judgement on whether a particular conflict was right or wrong, but remembers those who fought in them either voluntarily or without choice.
Lieutenant General Robin Brims, a Christian who served in Ireland, Bosnia and Iraq, told Premier: "When the names on war memorials were read out [as a child], there were names of people who were clearly related to me.
"As a junior officer... Remembrance Sunday then became much more personal, because on that Remembrance Day you remembered soldiers with whom you had been deployed on operations who had been killed.
"The advance of medicine, what paramedics were able to do, meant that many more people survived horrific wounds and live with them today."
Revd Steve Wild is President of the Methodist Conference joined Queen Elizabeth II and other church leaders to remember veterans in Whitehall today.
He told Premier: "My great uncle was killed in the First World War. He was a Christian man, he ran a Bible class, and he was killed in the Battle of the Somme. And it will be for me quite a poignant moment going there [to Whitehall] with the other church leaders and the Queen and all the others to think of him.
"I travel round churches, I have done all my life, and you'll see there a list of names, and we say in that service: 'We will remember them.' That's something very precious to me because I believe Jesus knows everybody's name. In fact in Isaiah God says: 'Your name is written on the palm of my hands'.
"All those people, nothing's wasted. God's love is for them, because he knew them, and he knows and comforts us in our distress."
And Revd James Breslin, the county chaplain to the Royal British Legion in Northumbria, told Premier: "When I was younger I used to think it [Remembrance Sunday] should probably be allowed to die out, but over the years I've changed my mind, because I think it serves a hugely valuable role in reminding people of the genuine cost of war.
"You see the thousands of crosses marking the lives of individual men and women, many of whom were incredibly young. And it just reminds you of the cost of war."
"Part of what we do on Remembrance Sunday is... to give thanks to God that it means that those who consider going to war have the cost before them before they make such a decision."
