A new report, compiled by the Department for Energy and Climate Change, has shown that many of the UK's biggest energy suppliers are missing targets to help some of the country's poorer households, according to an article published by the Mirror.
The report has also highlighted a number of problems in the Government's Community Energy Saving Programme.
Originally launched in 2009, the programme was designed to cut bills and provide homeowners with energy-saving measures - such as wall cavity insulation.
Around 90,000 properties were due to benefit, but with the programme set to end in December, it has been revealed that up until June of last year, just 12,703 homes gained any sort of benefit from the scheme.
Energy firms were also set to work with the Government on the scheme; however, this hasn't been the case.
Caroline Flint, shadow energy secretary, stated: "The most sustainable way people can cut their power bills is by reducing their energy use.
"But the energy companies are failing to keep their side of the deal and help families and pensioners make their homes warmer and more efficient.
"If the big six energy companies can't sort this out themselves, Ofgem and the Government must not let them off the hook," she added.
