I had not seen that, so it would be ill-judged to comment on it. I can point the hon. Gentleman to a very fine article from only last week in, I believe, the Colchester Gazette, authored by the local MP, on why we need the most ambitious Government investment in social housing since the second world war. I will touch on that in a little bit.
Sadly, we have an estimated 4,677 people sleeping rough on our streets, and 277,000 homeless households. That is due in part to a lack of security in the private rented sector, which, as I mentioned, is now the biggest single cause of homelessness. We have areas where demand massively outstrips supply, including some of our major cities and large towns, with Colchester being a prime example, so landlords will not let to those in receipt of benefits.
The Government have done some great work, which is starting to make a difference and gives some reason for optimism, including the Homelessness Reduction
Act 2017. I was pleased to speak at all stages of its passage and to sit on its Bill Committee. There is also the £28 million Housing First pilot, the rough sleeping initiative and the Somewhere Safe to Stay pilot. There is funding for non-UK nationals sleeping rough. There are rough sleeping support teams and mental health support outreach workers. Improvements have been made to StreetLink and there are homelessness experts in jobcentres. Those are all part of that £100 million package to support the rough sleeping strategy announced last year.
My concern is that, worthy, important and valuable as those programmes are, they treat the symptoms, not the cause. What do we need to do? The first thing I should say to the Minister is that I do not have all the answers. However, I have some suggestions on ways in which we can start to prevent homelessness and address the issue. First, we need a full nationwide roll-out of Housing First as quickly as possible. The three pilots were important and a great start, but we know that it works; we have seen it work in other countries, particularly in Scandinavia, where rough sleeping has been entirely eradicated. Secondly, fewer than half of local authorities have a night shelter, so we need to fund and build more of those. Regional hubs are hugely important.
As the hon. Member for Bermondsey and Old Southwark mentioned, we need to lift the freeze on the local housing allowance, which was introduced in 2016. We also need to embed and fully fund the Homelessness Reduction Act. It is a great piece of legislation, but we must monitor it to make sure that it is working and is fully funded and, equally importantly, that local authorities use it to its full and interpret it in the right way. That is hugely important, particularly in relation to the duties it places on them. As the hon. Gentleman also mentioned, we need a help-to-rent scheme. We need to look at people who have no recourse to public funds. In London and some of our big cities, between 30% and 40% of rough sleepers are non-British nationals and are not entitled to any support, so we need to find a solution for those individuals.
We need to start treating homelessness, and particularly rough sleeping, as a health issue. I mentioned alcoholism, drug addiction and mental health issues. We need mental health support workers to go out with every outreach team up and down the country. I am pleased to see that £30 million will be invested in that regard, which will make a huge difference. For the Minister to say at one of our all-party parliamentary group meetings that the Department very much sees rough sleeping and homelessness as a health issue was an important step change.
