British households are to receive a government subsidy of 5000 pounds (around 5910 euros) if they swap their gas boilers for more climate-friendly heat pumps.
The grants, which are due to be available in England and Wales from April this year, are part of a series of climate action measures announced by the UK government on Tuesday ahead of the COP26 world climate conference in Glasgow.
The millions of houses, often poorly insulated and heated by gas, have generated around a fifth of Great Britain's CO2 emissions in recent years.
Prime Minister Boris Johnson wrote in a guest article in the "Sun" that they wanted to make the installation of heat pumps more affordable so that they would be the more sensible solution for homeowners and landlords. But it will not happen that "the green shirts of the boiler police with their sandal-clad feet kick the door" to remove the old boiler.
According to the government's plans, no new gas boilers will be installed from 2035.
However, critics point out that this is not a ban, just a declaration of intent.
In addition, organizations such as Greenpeace and Friends of the Earth consider government support, for which London is budgeting £ 450 million over the next three years, to be inadequate.
According to a BBC report, switching to a heat pump costs 6,000 to 18,000 pounds, depending on the size of the household.
