As I have said, we are increasing funding for this issue. We are spending £1.2 billion. This year, we are adding £430 million and more—for example, the £112 million I have devoted this year to the rough sleeping initiative. That is a 30% increase, and the funding the previous year was more than the year before that, so the Government are giving this national issue the resources it deserves. I hope that meets with approval across the House.
We are also taking action by implementing the Homelessness Reduction Act 2017, which will play a crucial role in tackling this issue. I pay tribute to my hon. Friend the Member for Harrow East (Bob Blackman) and all those who played an instrumental role in taking this ambitious legislative reform forward. It means that everyone, not just those deemed a priority, can get the support they need to prevent them from becoming homeless. The legislation also means that people can access support earlier, with new duties on public bodies, from the NHS to our prisons, to intervene earlier, and councils are now providing support of up to 56 days, ahead of someone needing help finding secure accommodation.
Since the Act was implemented, more than 130,000 households have had their homelessness successfully prevented or relieved, and nearly two thirds of the applicants receiving help have been single households who previously would have been less likely to have been offered support.
The duty to refer, which came into force in October 2018, is also encouraging strong local partnerships. It requires public authorities such as our prisons, our emergency departments and Jobcentre Plus to refer service users who they think may be homeless, or threatened with homelessness, to a local housing authority of their choice. That is a clear example of public services working closely together in the interests of the most vulnerable in our society.
We are also taking decisive action on the delivery of fairer, more affordable housing of all tenures, so that we can prevent and reduce homelessness and rough sleeping. The Government have delivered more than 464,000 affordable homes since 2010. Our commitment to increasing the housing supply means that we will go even further than that, delivering, on average, more affordable homes each year than the last Labour Government—and there is more to come, with 250,000 more new affordable homes due to be delivered by March 2022 through the affordable homes programme, which we have boosted with a further £9 billion.
In our manifesto we committed ourselves to a further affordable homes programme, which I hope will be even more ambitious. That commitment is underlined by our manifesto pledge to publish a social housing White Paper, which will set out more measures to empower tenants, provide greater redress and better regulation, and improve the quality of social housing.
