Free Boiler Grant London — ECO4 Scheme 2026
Millions of London residents may be eligible for a free boiler grant under the Government's ECO4 scheme. Despite London's high property values, a significant proportion of households — particularly in social housing and private rented accommodation — have older, inefficient boilers and qualify for free replacement.
London has a diverse housing stock, from Victorian terraces in South London to post-war council estates in East London. Many of these properties have EPC ratings of D or below and are heated by ageing gas boilers. The ECO4 scheme covers all London boroughs, and both homeowners and private tenants (with landlord consent) can apply.
We cover all 32 London boroughs including Barking & Dagenham, Barnet, Bexley, Brent, Bromley, Camden, Croydon, Ealing, Enfield, Greenwich, Hackney, Hammersmith & Fulham, Haringey, Harrow, Havering, Hillingdon, Hounslow, Islington, Kensington & Chelsea, Kingston, Lambeth, Lewisham, Merton, Newham, Redbridge, Richmond, Southwark, Sutton, Tower Hamlets, Waltham Forest, Wandsworth, and Westminster.
