Question to the Department for Levelling Up, Housing & Communities:

To ask the Minister for the Cabinet Office, whether solar energy and storage will be mandated in all new homes before 2025 when building regulations Part L are next reviewed.

The Building Regulations set minimum energy performance standards for new homes and non-domestic buildings. They are deliberately couched in performance terms and do not prescribe the technologies, materials or fuels to be used.

We are, however, planning to consult later this year on an uplift to the Building Regulations energy efficiency standards where there are safe, practical, cost-effective, and affordable opportunities to do so.
