The Homes for Ukraine programme, to be rolled out this week, will allow individuals, charities, community groups and businesses to bring people escaping the war to safety – even if they have no ties to the UK.
Britons offering accommodation to Ukrainian refugees through the new route will receive a “thank you” payment of £350 per month.
It comes as the Government has been condemned for the speed and scale of its efforts to bring fleeing Ukrainians to the UK.
The UK’s ambassador to Ukraine, Melinda Simmons, told The Sunday Times she “totally gets the criticism” levelled at the Government over its approach to the issue so far.
Until now, the visa route for people fleeing the war in Ukraine has been limited to those with family members settled in the UK.
Ms Simmons told The Sunday Times: “I’m approached directly by British nationals who tell me where they are, and that… the visa appointment is in three weeks and they’re ready with their biometrics but they’re stuck in a hostel with two young kids.
“I get these messages every day. We maintain personal contact with these people and our rapid deployment teams at the border are absolutely brilliant.
“It just needs to be matched now, with enough resource to be able to process people with the speed that we need. I know that the visa centres are now responding to it with a better queuing system and more people.
“But if this is going to rise then obviously it’s going to have to continue and the capacity is going to have to grow in a corresponding way.”
She added: “I know that the Home Office understands that and has now and is moving as quick as they can to deliver that.”
The Government said it was “standing shoulder to shoulder” with the people of Ukraine, and had made it easier for those with valid Ukrainian passports to come to the UK.
People sponsoring refugees through the new uncapped route will be required to commit to the scheme for a minimum of six months, but are encouraged to keep up the offer for as long as they can.
Those offering accommodation will be vetted and Ukrainian applicants will undergo security checks. A website gathering expressions of interest is set to launch on Monday.
Ukrainians who are sponsored through the new humanitarian route will be granted three years’ leave to remain in the UK, with entitlement to work and access public services.
Michael Gove, the Levelling Up, Housing and Communities Secretary, said the UK “stands behind Ukraine in their darkest hour”, and urged people to “join the national effort” to help refugees.
But Labour cautioned that “too many questions remain unanswered”.
Shadow levelling-up secretary Lisa Nandy said it was unclear what support would be offered to vulnerable children and older people, whether provision would made for unaccompanied children, and what help would go to local government, sponsoring organisations and housing providers.
She said if Britons were required to have a prior connection to a Ukrainian family to sponsor them, that would be “a severe limitation”.
