<p>The modelling used to set the ECO4 targets was based on estimated costs in 2021 prices, with an allowance for general inflation over time. Given the context of much higher inflation than expected, our recent ECO+ consultation sought stakeholder views on our cost assumptions, and we will be summarising these views in our forthcoming Government Response. The Department also recently gathered evidence on the costs of installing loft insulation and cavity wall insulation from installers, which is being used to update our assumptions. We will assess the impact of our updated cost assumptions on ECO4 and take action, if necessary.</p> |
