A national two minutes' silence is also expected to take place during the service.
Can you attend the Queen's funeral?
Sadly, only invited guests are allowed to attend the funeral or private committal service of Her Majesty The Queen as around 2,000 heads of state, dignitaries, European royals, and other key figures will be invited to Westminster Abbey.
However, huge crowds are expected to gather along the Mall from the Abbey in London and the Mall’s bollards will be removed to make space for mourners, according to reports.
How can I pay my respects?
Thousands of people have already flocked to the Queen's residences to pay their respects, laying flowers outside the gates with messages of their condolences.
The public can pay their respects to the late Queen by visiting Her Majesty who will be lying-in-state in Westminster Hall from Wednesday for a four-day period.
The Cabinet Office has also warned of crowding and delays on some public transport as people seek to pay their respects.
A government spokesperson said: "We recognise that many people will travel to Buckingham Palace and other royal residences as a mark of their respect.
"We expect large crowds, which can pose risks to public safety. Those who do travel are asked to follow any instructions given to them by stewards and the police. We expect significant crowding and delays on some public transport. The public should check ahead and plan accordingly.
"As you would expect, a number of organisations will now be making practical preparations including contingency planning for the state funeral and related events."
'Access to some areas, especially in central London, will be restricted, with road closures and diversions that will cause delays to vehicles and pedestrians.
'Those who wish to lay floral tributes near royal residences in London, Windsor, Edinburgh, Balmoral and Sandringham are asked to do so only in designated areas, as directed by stewards. Further details will be made available shortly.'
