Britons trapped in Gaza were given hope of escape on Wednesday as the border crossing with Egypt opened.
Foreign Secretary James Cleverly confirmed teams are ready to help UK nationals flee the besieged Palestinian territory via the Rafah crossing.
For weeks only small amounts of aid have been allowed through the stretch into Gaza, which has been subjected to shortages of food, water and fuel as bombs rain down.
Western officials said that it is likely the departure of British Nationals from Gaza "will take place in stages over the coming days".
The UK is "working closely" with Egyptian and Israeli authorities, they added.
It is understood that the crossing will be open for limited time periods to allow specific groups of foreign nationals and the seriously wounded into Egypt.
Israel, Hamas and Egypt all agreed to allow for limited evacuations from the Gaza Strip, as well as aid to get into the territory.
Mr Cleverly said: “UK teams are ready to assist British nationals as soon as they are able to leave.
“It’s vital that lifesaving humanitarian aid can enter Gaza as quickly as possible.”
Deputy Prime Minister Oliver Dowden also said the Government “stands ready” to aid the exit of British nationals from the area.
It comes as Gaza City was plunged into another communications blackout early this morning.
Telecoms providers Paltel Group and Jawwal reported a “complete disruption” of all phone, internet, and other communication networks within the blockade for the second time in five days.
It follows Israel vowing to lay siege to the Gaza Strip in the wake of the October 7 attacks by Hamas, where more than 220 civilians were kidnapped by terrorists and hundreds more murdered.
Aid workers warned that such blockades on communications make providing humanitarian services nearly impossible and it risks making a dire situation for thousands of innocent people far worse.
Israel fired a barrage of missiles at Gaza City overnight, levelling apartment blocks. The densely populated Jabalia refugee camp was hit in a blast yesterday as Israel targeted a Hamas commander who its defence forces said had been hiding there.

At least 50 Palestinians were also said to have been killed.
Mr Dowden said Israel’s air strikes on the camp were part of the “terrible nature” of the conflict.
Asked by Sky News whether international law had been broken, the Deputy PM said: “Hamas is a terrorist organisation that has murdered in cold blood over 1,000 innocent Israeli men, women and children, and now seeks to hide amongst the civilian population. This is a very difficult conflict.
“We continue to urge the Israeli government to abide by international law. I believe that the Israeli government is continuing to do so against an enemy that hides among civilians.”
Labour called for the Disasters Emergency Committee (DEC) to set up an appeal for Gaza, matched by taxpayer funding.
Shadow foreign secretary David Lammy and shadow cabinet development minister Lisa Nandy were in Cairo for talks about the crisis.
Mr Lammy said: “There is an urgent need to alleviate humanitarian suffering in Gaza and a DEC appeal with government backing would help galvanise the public’s efforts to help those in need.
“We must also begin to plan for the large-scale reconstruction that will be required for the people of Gaza to live in peace and dignity. In the long term, there can only be a political solution based on a two-state solution.”
The Israeli military said 11 soldiers were also killed in fighting in Gaza yesterday, the biggest one-day loss for the armed forces since Hamas gunmen attacked southern Israel on October 7.
According to the World Health Organisation, two hospitals have been damaged, as well as critical resources, including ambulances, in the conflict.
