Solar panels top householders' energy saving wish-list, despite draughty homes being the biggest complaint, a survey has suggested.
Some 44% of those asked by the Energy Saving Trust said they lived in a draughty home.
Condensation was a problem for 38% of those asked and 29% said they had mould.
The Trust said that homes were better insulated than in the past, but more could be done.
The survey suggested that 24% of homeowners who lived in draughty homes said they were planning to install energy efficiency measures.
However, renewables - such solar panels - rated above wall and loft insulation and draught excluders as the ideal choice, if money and inconvenience were not an object.
A spokeswoman for the Department of Energy and Climate Change said: "The best way to save money and cut bills is to make homes warmer. We want people to benefit from the wealth of government support out there."
