A call to action to improve the lives of people who are homeless or at risk through evidence-led change.

Sign the pledgeBuy the bookRead the blog

In 2020 we brought together a wide-ranging group of leaders in government, academia and the not for profit sector to write the book Using Evidence to End Homelessness, which calls for greater experimentation and better use of evidence in efforts to end homelessness. Their numbers have since grown.

End it With Evidence builds on this foundation to mobilise, at this moment of great change, a growing chorus of ‘what works’ champions to ensure that, as part of aiming to end homelessness for good, we use this opportunity to understand how to end it effectively. How to end it sustainably. And most importantly, how to improve the lives of people affected by homelessness.

The campaign is founded on the following principles, which call upon leaders at all levels to:


Build the evidence of the policies, practices and programmes that achieve the most effective results to improve the lives of people who are homeless or at risk.


Build the capacity needed to act promptly on the best knowledge available to improve decisions and help limited resources go further.


Use evidence-led communications to change the conversation around homelessness, challenge stereotypes, and make sure that homelessness is not a defining factor in anyone’s life.

Campaign Ambassadors

The campaign's ambassadors below support the three pledges. Like us they believe that 2021 could mark a definitive turning point in homelessness. But only if we can be confident that we are working towards ending, rather than managing, homelessness. Join us.

Chief Executive, Funders Together to End Homelessness

We cannot continue to sit at the same tables having the same conversations about a stubborn problem and expect it to change. By funding the right solutions, the ones we know will make a difference, we can seize the opportunity to make great change worldwide. And, by deploying good quality evidence to tackle the underlying causes of homelessness - such as structural and racial inequities, we can solve the problem of homelessness itself.
Bob Blackman

MP, Co-Chair All-Party Parliamentary Group on Ending Homelessness

Homelessness is not a given. Too many opportunities to prevent homelessness are currently being missed. This is especially true for people leaving the care of the state, including those leaving prison and the care system, as we found during our APPG inquiry into prevention. By working together to promote long-term, evidence informed sustainable solutions to it, we can ensure future generations are not at risk of the perpetuation of homelessness and end this national crisis.
Neil Coyle

Neil Coyle

Co-Chair, APPG on Ending Homelessness

I have seen first-hand that the causes of homelessness are varied and complex but not insurmountable.  As co-chair of the All Party Parliamentary Group on Ending Homelessness, I am pushing for focused and evidence-based interventions to help people who are homeless, and to get people who are sleeping rough off the streets. As homelessness continues to rise each year, with the likelihood that it will surge due to the Covid-19 pandemic and its economic aftermath, now more than ever it is important to use the APPG as a platform for bringing together parliamentarians from all parties to unite and campaign on workable policy solutions to ending homelessness.

Currently we often know what problems need to be solved, but may not be making the right kinds of investments to address them because the evidence is weak or lacking. To improve positive impact we need to be able to do the right things well. By engaging in robust evaluation of targeted, practical responses that seek to prevent or alleviate homelessness, we arm ourselves with the knowledge we need to end homelessness.

We need to make sure that people who are making decisions in every level of government have the ability to use data in decision making and policy making. When we've not made progress it’s because we haven’t figured out what needs to change and measured our progress towards it. We’ve also not had effective collaboration across service providers. Getting people together to look at and assess data is key.
Alison Griffin

Alison Griffin

Chief Executive, London Councils

London faces the most severe homelessness crisis in the country and the capital’s local authorities have a pivotal role to play in addressing this. As the cross-party group representing all 32 boroughs and the City of London Corporation, London Councils fosters collaboration across the capital and works with the government and other key partners to tackle homelessness. It’s essential that we use evidence-based policies and practices to achieve the best possible results for those experiencing homelessness and to do everything we can to help end homelessness altogether.
Rosanne Haggerty

Rosanne Haggerty

President and Chief Executive Officer, Community Solutions

We firmly believe that with evidence, ending homelessness is achievable, and together we can redefine what is possible in the movement to end homelessness. By applying moral courage, data-driven thinking, and a system-wide approach we are already seeing tangible results and communities achieving what was previously considered impossible.
Paul Matthews

Paul Matthews

Chief Executive, Monmouthshire County Council

At a time when our citizens are concerned about the impact of the pandemic on their families, income, housing, and wellbeing it is crucial that we don’t leave anyone behind. Leaders in local areas have difficult jobs to do, but making more effective use of data and evidence can help us be more effective and aid us in our goals. Join us.

Founder, Institute of Global Homelessness at DePaul University, CEO of De Paul International

I hope in the future we will be more humble, that we have the courage and the wisdom to say we don’t know which idea is better, but we're systematically going to find out. If we could get that, I genuinely believe it would change the world.
Geoff Mulgan

Sir Geoff Mulgan CBE

Professor of Collective Intelligence, Public Policy and Social Innovation at University College London

This is a decisive moment for homelessness in the UK and in many other countries.  We have a chance to shift what is thought of as possible or normal. At a minimum we should use this opportunity to improve outcomes for people experiencing or at risk of homelessness by focusing on what works, pushing for interventions to be rigorously evaluated, and directing investments towards prevention. We should also be bold in thinking about what might be possible over the next decade if we can raise our ambitions.
Alex Murray

Commander Alex Murray OBE

Met Police

I have seen first hand in my work the positive impact that applying rigorous evidence to complex problems can have. Just as in evidence-based policing, to tackle homelessness effectively we must take a step back, evaluate how and where we are seeing success, and what simply doesn’t work, and commit to creating a culture that brings real, lasting solutions into our communities.
Ian Rutherford

Rev. Ian Rutherford

City Centre Minister in Greater Manchester and Faith Sector Lead on Homelessness for the Mayor

Homelessness is complex and identifying the most effective solutions won’t be simple - we know that much from our work in Greater Manchester. It’s no surprise that there is public scepticism about our ability to end or even significantly reduce homelessness, or positively engage with people who refuse ‘standard offers’ for help. Making policy and funding decisions based on the best possible evidence will help bring confidence that we can do it.
Jeremy Swain

Adviser on homelessness and ex-CEO Thames Reach

Governments must be equipped to help as many people as possible escape the distress and trauma of homelessness. Better evidence and data is crucial if we are to respond promptly and direct investment effectively, ensuring every penny invested in homelessness solutions is well spent.

Jean Templeton

Chief Executive, St Basil's charity

We collect data so front-line teams can see what they’re doing well, where they’re struggling and talk to colleagues who may be achieving outcomes they’re struggling with and learn from each other.  
It isn’t just about data, however. On its own, data may be ignored, or may prompt a defensive reaction. We blend this information by weaving in young people’s lived experience. The knowledge and experience young people have of their context and our services is absolutely critical to us.
Elena Whitham

Elena Whitham MSP

MSP for Carrick, Cumnock & Doon Valley

In my work with the COSLA and Scottish Government’s Homelessness Prevention and Strategy Group, I have seen first hand the benefits to be gained from supporting local authorities embrace an evidence-led approach to tackling homelessness. As illustrated by the great leaps forward we have seen in other fields like international development, we can achieve significant results in local areas if we gradually shift attitudes and behaviour and use better information to guide vital investments.

Stephen Timms MP

MP for East Ham

My East Ham constituency in London is at the very sharp end of the housing crisis.  Rents are unaffordable on the wages of many working families in the area. East Ham has the highest rate of household overcrowding in the country, and 27,000 people are on our social housing waiting list. I tell people at my constituency surgeries it might be 15 years or more before they are allocated social housing. Before the pandemic, Newham had the third highest rate of street homelessness in London. We need to address these challenges with evidence and research.

Sign the pledge

I believe that all those working to end homelessness, should join the movement to end it with evidence by: 


Building the evidence of the policies, practices and programmes that achieve the most effective results to improve the lives of people who are homeless or at risk.


Building the capacity needed to act promptly on the best knowledge available to improve decisions and help limited resources go further.


Using evidence-led communications to change the conversation around homelessness, challenging stereotypes, and making sure that homelessness is not a defining factor in anyone’s life.
