How Thrive LDN reached 600,000 Londoners and built lasting system capacity

The challenge

Common mental health conditions and psychological distress have increased consistently across London over the past two decades. Complex, overlapping factors — the rising cost of living, widening inequality, structural racism, and the long shadow of the pandemic — shape the mental health of Londoners in ways that clinical services alone cannot address.

The challenge is compounded by fragmentation. Awareness campaigns, peer support programmes, and crisis prevention networks have historically operated in silos across 32 boroughs and the City of London, limiting their collective reach and making it difficult to build the population-level change that London’s mental health needs.

Thrive LDN was established as a coordinated system leadership response to this challenge: a citywide partnership that exists to promote mental wellbeing among all Londoners and their communities, and help prevent mental ill-health. This work is delivered through a partnership spanning NHS London, the Greater London Authority, the Association of Directors of Public Health London, and all London Integrated Care Boards.

Our approach

TPHC hosts the Thrive LDN partnership, providing a system leadership framework that creates efficiencies through a once-for-London approach and regional economies of scale across public mental health activity. In 2025/26, the programme’s work spanned four interconnected areas.

Anti-stigma campaigns and digital engagement targeted communities where the gap between mental health need and help-seeking is widest. The #TakeWhatsYours initiative challenged the stigma of financial hardship, directing residents to local support and generating over 10,000 campaign clicks. Great Mental Health Day 2026, held on the last Friday of January each year, brought together 5,500+ partner organisations, produced an interactive borough activity map accessed 2,846 times, and hosted a virtual suicide awareness training session attended by over 450 participants.

Frontline workforce development was delivered through the Gift of Reconnection trauma-informed practice training series and in-depth community workshops, reaching practitioners across London and beyond. These built capacity to support residents experiencing trauma in everyday settings rather than only in clinical environments. The programme worked with people with lived experience and academic partners to co-lead research networks focused on upstream prevention and anti-racist interventions.

Suicide prevention infrastructure was sustained through real-time surveillance systems and multi-agency prevention networks. A dedicated Thrive LDN campaign promoting Zero Suicide Alliance training supported close to 38,000 Londoners to take free, online suicide awareness training, closing in on 500,000 Londoners trained since 2019.

Community resilience and financial wellbeing work connected residents to practical support, pairing digital resources with in-person financial advisors to translate engagement into tangible financial gains. A three-year partnership project on the nexus of climate action and mental health was also advanced, alongside the publication of the Shifting Power report on systemic inequalities and continuation of anti-racist research networks. Robust Equity Impact Assessments were undertaken for all activities.

The impact

In 2025/26, Thrive LDN reached over 600,000 Londoners through digital mental health campaigns delivered across 10 boroughs. Great Mental Health Day 2026 engaged 5,500+ partner organisations and mapped 67 community activities across 28 London boroughs, making it easier for residents to find local connection opportunities close to home. The Great Mental Health Day suicide awareness training session in January drew 450 attendees; of the 400 who gave feedback, more than 98% would recommend it and 75% rated it 5 out of 5 (average 4.7 out of 5). The campaign was formally recognised by the Minister for Mental Health as a key part of London’s prevention strategy.

More than 5,000 practitioners across London and beyond were equipped with trauma-informed skills. Of those who participated in in-depth workshops, 90% reported increased confidence in applying these skills in their professional roles.

The Grassroots Community Resilience Pilot was delivered to test how to foster belonging and wellbeing through dedicated microfunding. Feedback from grassroots organisations and community groups consistently showed that situating support within familiar cultural or religious frameworks is more effective for communities at greater risk of poor mental health.

In financial wellbeing projects, 70% of participants reported a measurable increase in their confidence managing personal finances. This was evidence of a key programme learning: digital tools achieve their best results when paired with human support. Financial advisors working alongside residents helped them translate digital engagement into actual financial gains, and this insight is now shaping the next phase of Thrive LDN’s community resilience work.
