| Most households saw their energy bills rise on 1 October, as the new energy price guarantee came into effect. However, the rise was less than had previously been expected after the government announced it would cap domestic bills to prevent widespread hardship. | Most households saw their energy bills rise on 1 October, as the new energy price guarantee came into effect.
