Bob Blackman is MP for Harrow East.

A year ago this month, I was proud to see my Homelessness Reduction Act given Royal Assent to become the first major change to legislation on the subject in England for nearly 40 years.

Today, 3rd April, marks the date that it comes into force, after a year of preparation by local authorities across the country. This piece of ground-breaking legislation came about after I was drawn in second place in the Private Members’ Bill ballot in 2016. It’s a comprehensive change to the law which will shift the emphasis firmly towards preventing homelessness from ever occurring in the first place, and it will ensure that care leavers, ex-offenders, NHS patients, armed forces veterans and other vulnerable groups will receive help and advice for the first time.

From the moment I was drawn in the ballot, I was inundated with requests to use the opportunity to further interests or a particular cause by multiple groups. I settled on homelessness reduction after giving thought to issues I have seen in my time in politics having been a councillor and member of the London Assembly before entering the House of Commons.

A lot of work went into ensuring the Bill would be workable and credible and I was naturally pleased that it gained valuable backing from the Government and all opposition parties. My colleagues on the Communities and Local Government Select Committee deserve particular mention for their support, as this was the first time a Private Member’s Bill was given pre-legislative scrutiny by a Select Committee, which made a big difference in ironing out the finer points at an early stage.

Crisis, the outstanding national homelessness charity, deserve a great deal of credit for helping to support the early formation of the Bill through their extensive groundwork, and I also owe thanks to Shelter, St. Mungo’s and several other charities for their support as well. The Residential Landlords Association, the National Landlords Association, the Local Government Association, and London Councils are also to be commended for having the insight and vision to recognise the need for this legislation and I am also grateful for their support.

Throughout the process I was repeatedly surprised by how dated homelessness law was and how long had passed since proper scrutiny by lawmakers.

Fortunately, the Housing (Wales) Act 2014 had come into force in April 2015, so the experience gained from that piece of legislation was perfectly timed to help inform measures put forward in the Homelessness Reduction Act. Wales saw a 69 per cent decrease in the number of households owed the main homelessness duty, with only 1,563 households owed the main homelessness duty in the first year of the new prevention and relief duties contained within that legislation. While there are obvious differences between the nations, this was a demonstration that shifting the balance towards prevention work could really make a difference.

Drawing on lessons from Wales, there is a strong evidence base to suggest that the costs of transforming local authority services towards prevention work prior to homelessness occurring will be rapidly offset by the savings to local authorities on temporary and emergency accommodation. As of the end of last year, there were 78,930 recorded households in temporary accommodation, with 54,370 (69 per cent) placed in temporary accommodation in London, and the number of families with children stuck in completely unsuitable B&B-style accommodation on the rise. The National Audit Office (NAO) report on homelessness in September 2017 showed that, of the £1.1 billion spent by English local authorities in 2015-16, £845 million was spent on temporary accommodation, and this figure has only continued to increase.

I am very pleased that the Government is funding the initial implementation of my Act to the tune of £72.7 million over the next two years, helping local authorities to make the adjustments and provide the new services needed to turn things around and change how we approach homelessness entirely. After two years, I believe there will be fewer people hitting the point of becoming homeless in the first place, with local authorities empowered to step in and offer help and advice up to 56 days before the crunch occurs, in turn causing a reduction in the need to use unsuitable temporary accommodation.

Of course, this piece of legislation cannot be considered a fix-all. Homelessness is typically the end point which occurs due to numerous other issues and no one thing can provide a complete solution. The Act places a duty to refer onto agencies like the NHS, the prisons service and Jobcentre Plus, to try and ensure no one is missed in the system, and it also reinforces legislation to ensure Private Rented Sector accommodation has been inspected for suitability prior to it being offered. I hope all the different measures contained within this legislation will really make a difference on the ground and I intend to continue to press the Government to keep monitoring it and listening to local authorities as they feed back on it.

When it comes to trying to prevent homelessness and rough sleeping in this country, I hope that today is the day we can say that things really started to change.
