Some 120,000 children will be homeless this Christmas, according to housing charity Shelter.

However, you won’t – or you shouldn't – see these children on the streets. Most of these minors, with their families, will be forced to find emergency temporary accommodation such as hostels or bedsits.

But what should you do if you see a young person sleeping rough?

"No child should ever be on the streets in modern day Britain. Anyone coming across an unaccompanied homeless child should immediately alert the authorities, whether that be the police or local social services," Matt Downie, policy and external affairs director at homlessness charity Crisis, told The Independent.

By law, anyone under the age of 18 is vulnerable and as such is classed as being in priority need for housing by their local council, which has a duty to find them somewhere to sleep.

However, sources from multiple charities told The Independent that identifying minors can be particularly difficult, especially those who may be 16 or 17.

The Child Rough Sleepers Project reported in 2014 that numbers of homeless children across Europe have risen, despite increased preventative and protective measures being introduced over the last 20 years.

The research found children who became homeless after running away, being thrown out of home or care, or other factors leading to them sleeping rough, were at high-risk of sexual exploitation, abuse and crime.

According to homelessness charity Streetlink, rough sleepers often go unnoticed by local services because they remain out of sight and move from place to place.

Mr Downie encouraged minors aged 16 to 17 who find themselves living on the streets to approach their local authority housing office as soon as possible. Members of the public can also contact Streetlink, who would arrange to make contact with the individual concerned and connect them to local services.

"Anyone in this age group will automatically be entitled to housing help from their council. Unfortunately for people aged 18 and over, this often isn’t the case. That’s why the Homelessness Reduction Bill, which is currently making its way through parliament, is so urgently needed," he said.

"If passed, this crucial bill will help to make sure all homeless people can get the support they need, regardless of their age."
