Sutton council schemes, planning and neighbourhoods
Sutton residents on low incomes can get free home improvements through the GLA's Warm Homes: Local Grant, and a long-standing Article 4 direction means some homes need permission for roof alterations. Here is what applies before you get quotes.
Council scheme
Warm Homes: Local Grant (GLA)
The GLA runs this government grant for 31 London councils, with free or subsidised upgrades that can include solar panels and batteries where an assessor finds them suitable. It is for privately owned or rented homes rated EPC D to G, with household savings under £25,000 and usually a household income of £36,000 or less, an eligible postcode or certain benefits.
