The objectives are: 1.Demonstrate accelerated transition to Net Zero at a neighbourhood level with scalability for wider borough rollout. 2.Promote a holistic place-based approach by combining retrofit projects with other interventions aligned to decarbonisation without creating personal debt or eroding household savings. 3.Address cost of living pressures by improving energy efficiency, reduced consumption, and provide new options for energy self-generation. 4.Develop a blended finance model which supports community-driven interventions including place-based green and blue infrastructure. Leveraging private capital alongside traditional grant funding. 5.Support retrofit across different building typologies– in areas of deprivation which include social housing and private rented sector. The demonstrator will comprise two adjacent estates totalling 1000+ homes. It will deliver deep whole house retrofit and at least two community co-designed interventions supporting environment and place
