Energy Grants in Tower Hamlets

Energy Grants & Fuel Poverty in Tower Hamlets

Tower Hamlets has London's highest proportion of flats at 72%, and a significant stock of post-war system-built council estates. Large estates like Balfron Tower and Lansbury Estate were built using concrete panel systems that perform poorly for thermal efficiency. The council's estate retrofit programme tackles these buildings holistically — external wall insulation, new windows, and communal heating upgrades — making individual ECO4 applications less relevant for council tenants but crucial for leaseholders.

For the borough's significant Bangladeshi and Somali communities, the council has developed culturally-appropriate outreach. ECO4 information is available in Bengali, Somali, and Mandarin, and community link workers from these communities are embedded in the referral process. This approach has doubled ECO4 uptake among non-English-speaking households compared to standard letterbox outreach.

Tower Hamlets has London's highest proportion of flats (72%) and has culturally-adapted its ECO4 outreach into Bengali, Somali, and Mandarin.

How ECO4 Is Delivered in Tower Hamlets

Tower Hamlets' leaseholders face a particular challenge. When the council upgrades a tower block's communal heating or adds external insulation, leaseholders (right-to-buy owners) can face service charge bills of £15,000-£30,000. ECO4 and LA Flex funding can cover individual improvements for eligible leaseholders, but the measures available are limited when the building is undergoing communal works. The council's dedicated leaseholder advice team helps navigate this complex intersection of communal and individual funding streams.
