As discussed in my article on the topic of renewable heat (England, Scotland and Wales to switch up their renewable heat subsidies (freeths.co.uk)), the Green Homes Grant, which supported the installation of energy efficiency improvements to homes was scrapped on 27 March 2021, with £300m of its funding diverted into the Local Authority Delivery Scheme (LAD) which is intended to help local authorities to target low-income and hard-to-treat households. The New Social Decarbonisation Fund has been set up to bolster this support, with a £160m pot for local authority and private social housing developers to retrofit properties with an EPC rating of D or below. 

As for the replacement of the Green Homes Grant, it is expected that a replacement scheme will be announced in the Heat & Buildings Strategy which is scheduled for release in the next few months.
