Head of Performance Insight and Planning in London

Do you want to lead planning and performance insight in a charity where your work creates real, measurable change? As our Head of Performance Insight and Planning, you will lead the organisation’s approach to business planning, performance, and insight—bringing clarity, alignment and accountability across St Mungo’s. You will translate complex data into clear, actionable intelligence for teams, senior leaders, the Executive and Board, ensuring that strategy, budgets and delivery stay tightly connected. You will also play a pivotal role in strengthening our data culture—building confidence, curiosity and evidence-led decision-making across the charity so we can deepen our impact for people experiencing homelessness.

Responsibilities

• Organisational goal‑setting and KPIs that align to St Mungo’s strategy and our Impact Roadmap.
• Annual and multi‑year business planning, working closely with Finance and senior leaders to align priorities, resources and delivery.
• High‑quality, insight‑driven performance reporting for colleagues, trustees, regulators and partners—enabling challenge, learning and action.
• Championing data literacy and evidence-based decision making across the organisation which drives continuous and transformative improvement in organisational impact.
• Working with Governance to ensure compliance with regulatory and statutory reporting requirements.

In this role you will be required to work flexibly for at least 2 days per week from our Central Office in London. This allows for training, in person collaboration, team building, line management and other relationship building opportunities. We support a flexible approach to work with opportunities for agile working for the rest of your week; from home, or other St Mungo’s London or regional locations.

About you

You are a strategic, values‑driven leader who brings analytical rigour, clarity and pace. You’re comfortable shaping new ways of working in complex environments, and you can turn ambiguity into sharp priorities and measurable outcomes.

You will bring:

• Experience leading enterprise-level performance and planning across strategy, budgets and delivery.
• A proven ability to turn complex data into compelling insight that influences senior decision‑makers.
• Experience developing outcome and impact models, such as Theories of Change or logic models.
• Confident use of quantitative and qualitative data, dashboards and automated reporting tools.
• Exceptional communication and stakeholder skills, able to make complex analysis clear and engaging.
• A collaborative leadership style that builds trust, shared accountability and a strong sense of collective purpose.

You do not need prior homelessness or housing experience – but you must bring a genuine commitment to St Mungo’s mission and values, including equality, diversity and inclusion.

We are working hard to create a diverse and fully inclusive culture where everyone feels valued and we welcome applications from all under-represented groups, particularly Global Majority candidates who are underrepresented at this management level.

While our Central Office is currently based in Tower Hill, London we plan to relocate in the summer of 2026 to a new space in Farringdon, London.

• A mission-driven organisation making a real social impact.
• A supportive, inclusive culture and opportunities for professional development.
• Competitive salary and generous benefits.
• A flexible approach to work with opportunities for agile working.
