More than 700,000 households in Great Britain have missed out on energy bill support, despite being eligible for it, according to a new analysis.
In February, the government said more than 900,000 households in places such as park homes and houseboats could get a one-off £400 payment - even though they did not have an energy supplier that could apply it automatically.
But government figures show that only about 200,000 applications were made before the deadline on May 31.
