Analysts call on government to make pumps mandatory for all new homes and scale up grants for installation in existing properties

The UK is lagging far behind France and other EU countries in installing heat pumps, research has shown, with less than a tenth of the number of installations despite having similar markets.

Only 55,000 heat pumps were sold in the UK last year, compared with more than 620,000 in France. Twenty other European countries also had higher installation rates than the UK.
