The UK government is set to ban gas boilers in new homes from 2025, with heating instead provided by low-carbon alternatives - e.g. heat pumps, heat networks and hydrogen boilers. (A report by the Business, Energy and Industrial Strategy committee says that bringing this ban forward two years (ie to 2023) could aid the UK's goal of net-zero by 2050, avoiding costly retrofits later. ) However, as it stands, any existing UK home will be able to buy a gas boiler until 2035. 13 years away! The focus must expand to increasing the efficiency of existing homes. Alas, it all boils (no pun intended) down to money. According to the Committee on Climate Change, it costs around 5x the price to install low-carbon heating in existing homes when compared to new houses. But does that mean we should not do it? No. It means we must find a way. And at a time of record rises in gas prices (which, I might add, has resulted in the government offering support of Є200 - Є350 per household), speeding up the transition to low-carbon heating sources will benefit both the climate and our energy bills in the long run. The savings will be long-lived - the transition is an investment.
