Boiler Plus is legislation introduced by the UK Government in 2018 as part of its ‘Heat in Buildings’ programme. This programme was designed to improve the ways homes in the UK use energy by increasing the efficiency of their heating systems. The introduction of Boiler Plus is the first major piece of legislation since the UK went “all-condensing” in 2005 - becoming the first country to do so in the process.
All boilers fitted in the UK must now have a minimum ErP efficiency of 92% and all installations must have time and temperature controls fitted, if they aren't already present and working correctly. For boilers that don’t already meet the target 92% efficiency, controls can be added to ensure compliance with this legislation. Further information on which Vaillant boilers already comply with Boiler Plus legislation and which controls should be fitted to ensure compliance, click here.
