The concept is well-liked, but there were several issues with the execution:
1) Lack of targeted support - the scheme announced by the Truss government, covers everyone in the country - both rich and old. Using taxpayer money to subsidise costs for the rich isn't popular with a lot of people. That would have been OK in the short term (until a better targeted scheme could be implemented), but the original Truss/Kwarteng plan was to have the scheme run for 2 years.
2) Borrowing - Labour favours funding energy bill support through a windfall tax on gas and oil companies who have been making big profits due to the war in Ukraine. The Truss government was opposed to such a tax, and was instead prepared to borrow tens or hundreds of billions of pounds to fund it (related to #1 - borrowing a lot to give rich people support with bills isn't popular, as everyone will be paying it back through taxes.).
The borrowing wasn't received well by conservatives, and sending more money to the rich energy companies wasn't liked by the left.
Of course, this was all on top of the other borrowing to cut taxes and so on that was announced and then de-announced.
