Sixty-two firefighters and doctors, who were scrambled to help with the biggest natural disaster since the 2004 Indonesian tsunami, pulled four alive from the rubble, including a two-year-old toddler called Mia, who spent three days trapped in debris.
Members of the UK International Search and Rescue Team were welcomed with applause from onlookers after they landed at Gatwick Airport early on Saturday morning.
Among those returning was Keith Bellamy, a member of the urban search and rescue team at Hampshire Fire and Rescue.
He said: "When we first arrived the country was in a state of chaos and confusion, with so many homes and public buildings having collapsed.
"We were based near the airport at Port au Prince and were helping to source fuel and purify water. The weather was extremely hot – about 38 Celsius in the shade – which made things even more challenging."
The 7.0-magnitude quake killed an estimated 200,000, according to Haitian government figures cited by the European Commission.
The UN Office for the Co-ordination of Humanitarian Affairs said: ''The government has declared the search and rescue phase over.''
A total of 132 people were pulled alive from the rubble of the devastated country, the United Nations (UN) said.
Countless dead remained buried in thousands of collapsed and toppled buildings in the capital, Port-au-Prince, while as many as 200,000 have fled the city of two million, the US Agency for International Development said.
As the UK teams headed back, International Development Secretary Douglas Alexander said: ''We should all be proud of the brave UK firefighters who worked tirelessly to help the Haitians, in difficult and dangerous conditions.
''I would like to thank them on behalf of the UK Government.''
He added: ''Their work is now done, but the international aid effort continues.''
A spokesman for the Department for International Development said: ''The search for survivors in Haiti is coming to an end.
''Following consultation with the UN, the UK team, like other international search and rescue teams, is now leaving. They have done all they can and the rescue effort is now moving on to another phase.''
Among those due to land are nine Greater Manchester firefighters who will be reunited with their families and colleagues at Manchester Airport.
They were involved in the successful rescue of Mia from her collapsed kindergarten school in Port-au-Prince.
Greater Manchester Fire and Rescue Service's chief fire officer Steve McGuirk said: ''It is with great pride that I welcome back safely the members of our service to their families.
''They have demonstrated tenacity, professionalism and courage in taking part in the UK national response to help the people of Haiti.
''The successes they have achieved are truly commendable in a time of such devastation and suffering and our thoughts remain with the people of Haiti as they continue to try and rebuild their country.''
John Bonney, president of the Chief Fire Officers' Association, was among those waiting at dawn at Gatwick to welcome the rescue team home.
"They have been working in extremely challenging conditions and their achievements in Haiti are testament to their exceptional commitment, professionalism and dedication."
Despite the end of the search and rescue phase, survivors were still being pulled from the rubble in Haiti on Friday.
In one part of Port-au-Prince, an Israeli search team pulled a 21-year-old man from a crevasse in what once was a three-storey home, the Israeli Defence Force said.
Shirtless and covered in dust, the man appeared to be either unconscious or barely conscious as he was hoisted on to a stretcher.
Elsewhere, an 84-year-old woman was pulled from the wreckage of her home, according to doctors administering oxygen and intravenous fluids to her at the General Hospital. Doctors said she was in a critical condition.
The life-saving efforts continued ahead of a global, star-studded fund-raising effort in the form of the Hope For Haiti Now telethon.
The show, broadcast from New York, London, Los Angeles and Haiti, included musical performances by a variety of superstars, including Beyoncé, Madonna, Taylor Swift, U2's Bono and the Edge and Keith Urban.
Hollywood star George Clooney, who helped organise the two-hour event, said: ''The Haitian people need our help.
''They need to know that they are not alone. They need to know that we still care.''
Donations by Britons to the Disasters Emergency Committee (DEC) appeal have topped £42 million as UK fund-raising efforts continued.
