Close to one million households who were initially missed from a programme designed to help people with their energy bills will be able to apply for support from the start of next year.
Care home residents, people who live on houseboats or in park homes and those who live off-grid will be able to get £400 in support - matching what is being paid out to millions of households with a more traditional energy set-up.
The support - which will also allow Travellers access to the cash for the first time - will extend to the 900,000 households in Great Britain that do not have a direct relationship with an energy supplier.
