'Huge challenge' to make all homes energy efficient

Jobs could be created by making energy-saving improvements to thousands of old homes, it has been claimed.

Better insulation and the latest energy-efficient technology could cut bills and help tackle climate change.

Christopher Jofeh, chairman of Decarbonisation of Homes in Wales Advisory Group, said it would be a huge challenge.

The Welsh Government said housing had an important role in the "green recovery" after Covid-19.
