No one doubts that that is a mammoth challenge for us all, which will have a wide range of impacts on people in different tenures and economic circumstances. The Scottish Government already makes support available—for example, through the home energy Scotland loan scheme, which involves interest-free unsecured loans of up to £38,500 per home to enable owner-occupiers to install energy efficiency and heating measures and a cashback scheme that provides eligible households with up to £13,500 towards zero-emissions heating systems and energy efficiency measures. A range of other schemes are also in place, including area-based schemes, which have been extended to include zero-emissions heating, and the Scottish Government has also introduced a top-up grant to support that process.
The member is well aware that we will continue to research the scale of the challenge and the steps that both this Government and the UK Government need to take. The actions of the latter will be necessary to make zero-carbon heating systems affordable by comparison with fossil-fuel ones.
