Is There A Ban On Gas Boilers?

NO! The supposed ‘ban’ on gas boilers was initially announced back in 2019 with plans to take effect as of 2025.

The reasoning behind the ban is to help the UK reach its goals of net-zero greenhouse gas emissions by 2050. 

Some misinformed members of the public have already needlessly replaced their gas boilers due to the nature of panic purchasing.

In reality, the following is actually TRUE when it comes to the ‘ban’-

  • The ‘ban’ actually states no new build properties can be built with a gas boiler installed past 2025

  • It is still legal to buy and install gas boilers in any home currently, and to continue to do so in older properties (anything that isn’t a new build) beyond the 2025 deadline

  • There is no legal requirement, financial penalties or general onus to remove and replace your existing gas boiler before or after 2025
