Hammersmith and Fulham council has launched a pilot scheme which gives all pupils free breakfast and lunch irrespective of their background.
Free breakfasts will be made available for free for all primary school pupils in the area from September.
And from January next year, pupils at two secondary schools in the area will take part in a free lunches pilot – regardless of their family’s income.
Council leader Stephen Cowan said: “It’s appalling that children are still going to school hungry in one of the world’s wealthiest capitals. We must put an end to that.
“Our schools are now the frontline in our war against hunger.”
The scheme, the first of its kind in England and Wales, is expected to benefit 10,700 children. It will be funded by cash paid by property developers to the council as part of planning permission conditions.
