UK energy efficiency push offers just a third of the investment needed, says report

IPPR says 12m homes will need to be refitted to meet net-zero targets but 3bn earmarked is not nearly enough

The government's new plans to upgrade the energy efficiency of homes will make only a fraction of the progress needed to help the UK meet its legally binding climate targets, according to a new study.

A report by IPPR, a left-leaning thinktank, has found at least 12 million homes will need to be fitted with low-carbon heat pumps and energy efficiency measures, such as insulation, over the next 30 years for the UK to meet its net zero targets.
