Energy Grants & Fuel Poverty in Lambeth
Lambeth's Victorian housing stock has been extensively subdivided into flats, creating unique insulation challenges. A typical Brixton or Clapham terrace, originally built as a single family home, now contains 3-5 individual flats. Coordinating insulation works across multiple freeholders, leaseholders, and tenants within a single building is the key challenge. South East London Community Energy (SELCE) helps organise building-level retrofit plans, making ECO4 funding more accessible to individual flat occupiers.
The Lambeth Together programme represents a pioneering integration of health and housing services. King's College Hospital's respiratory team refers patients living in cold, damp homes directly to Lambeth's energy advice service. GP practices in Brixton, Streatham, and Norwood can issue 'warm home prescriptions' that trigger LA Flex assessments. Early evidence shows these health-referred households are 60% more likely to complete ECO4 installations than those identified through conventional outreach.
Lambeth's health-referral pathway from King's College Hospital achieves 60% higher ECO4 completion rates than conventional outreach.
How ECO4 Is Delivered in Lambeth
SELCE's building-level approach is particularly suited to Lambeth's converted Victorian terraces. Rather than treating each flat individually, SELCE convenes building meetings where all occupants — freeholders, leaseholders, and tenants — discuss shared improvements. A whole-building internal wall insulation scheme, for example, delivers better thermal performance and lower per-unit costs than treating individual flats. ECO4 funding covers eligible occupants' share, while non-eligible households can access GBIS or contribute towards the reduced costs. This collaborative model has been especially successful in Brixton's Poets' Corner and Clapham's Narbonne Avenue conservation area.
