Ms Jowell, the Mayor of London Ken Livingstone and Transport Commissioner Peter Hendy will formally mark the second anniversary of the atrocities by laying flowers at Kings Cross station at the time of the bombings.
The Department for Culture, Media and Sport and Transport for London will arrange visits to the stations and to Tavistock square during the day for those families and survivors who wish it. They will also organise private gatherings for those families and survivors who wish to come together and reflect.
There will be no national silence and in line with the wishes of the families, there will be no large public event.
Ms Jowell said:
"The lives of those caught up in the terrible events of 7 July 2005 were changed forever on that day.
They have shown great courage in starting to rebuild their lives, but two years on the pain and grief is still unbearably raw. A formal act of remembrance at Kings Cross will give the country the chance to remember and pay their respects to the 52 innocent lives lost.
The families and survivors have chosen to mark the second anniversary of the atrocities privately, to reflect on the consequences of that day either alone, with family or with each other. "
The Mayor of London Ken Livingstone said:
"London will never forget the terrible events of July 7 2005 and the 52 innocent people who lost their lives.
In paying our respects, Londoners will continue to demonstrate the tremendous resilience and strength they displayed in the aftermath of the bombings and show the world that this city will not be divided."
London's Transport Commissioner, Peter Hendy CBE said:
"We will never forget those killed and injured on July 7, or the heroic acts of so many staff, passengers and members of the emergency services. It is an honour to represent London's transport staff and to pay respects on their behalf."
The memorial to commemorate the 52 people who lost their lives in the 7 July London bombings will be situated in Hyde Park's Lovers' Walk
