Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he has made of the compliance of boilers sold in the UK with minimum efficiency requirements.

Boiler standards fall under Building Regulations, and are a devolved matter. In England the current installation standards for boilers came into force in April this year. The Department engaged closely with the industry for two years before setting the standard to ensure the balance was right between ambition and deliverability. Our market assessment in 2017 found that two thirds of boilers available in the market already complied with the new standard. Since coming into force there is no evidence of boilers being sold below the 92% efficiency requirement. We will conduct an assessment in 2019 to ensure standards continue to be met, and a full review within five years.
