Both the British and Australian governments have announced that they will help home owners green their homes. Australia is offering 2.2 million homes a free insulation upgrade and more financial incentives for solar water heating. In the UK, it was announced that the government will help people with a full ‘eco-makeover’.

More than one in four homes in the UK will be offered a complete eco-makeover under ambitious plans expected to be announced this week to slash fuel bills and cut global warming pollution.

The campaign is thought to involve giving 7m houses and flats a complete refit to improve insulation, and will be compared to the 10-year programme that converted British homes to gas central heating in the 1960s and 1970s. Householders could also be encouraged to install small-scale renewable and low-carbon heating systems such as solar panels and wood-burning boilers.

In total, it is thought the Department of Energy and Climate Change will commit to cutting a third of greenhouse gas emissions from households by 2020.
