Questions & Answers

Q1 Eddie Hughes Con
Energy Environment
Context

The question pertains to the impact of recent changes in UK building regulations, specifically part L, which aims at improving the energy efficiency of new buildings.

Question

What assessment has he made of the impact on energy efficiency of the part L uplift in the building regulations. New homes now produce 30% fewer CO2 emissions, and new non-domestic buildings produce 27% fewer. The uplift will act as a stepping stone to the 2025 standards.

Answer from Lee Rowley

The part L uplift, which came into force in June 2022, delivered a significant improvement in energy efficiency. New homes now produce 30% fewer CO2 emissions, and new non-domestic buildings produce 27% fewer. The uplift will act as a stepping stone to the 2025 standards, which we will consult on in due course.

Q2 Eddie Hughes Con
Energy
Context

The question is about a simple additive known as EndoTherm, which can be added to both domestic and non-domestic wet heating systems to potentially reduce energy use.

Question

Is the Minister aware of a simple additive called EndoTherm, which can be added to both domestic and non-domestic wet heating systems for condensing boilers? Tests have proved that it reduces energy use and hopefully it will soon be standard assessment procedure-approved for testing. If he is not aware of it, will he meet me and Andrew Bean to discuss its properties?

Answer from Lee Rowley

I was not aware of it until now, but I thank my hon. Friend for highlighting it. As he knows from his time in the Department, our approach is agnostic on technology and materials, but where there are opportunities to find out more about how things are working and how we can improve things, I am happy to do so.
