Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, whether he plans to update domestic electrical safety guidance and regulations on plug-in solar.

Part P of the Building Regulations 2010 and Approved Document P make clear that electrical installations in dwellings should be designed and installed in such a way to protect people from electric shock and fire hazards. The Building Safety Act 2022 requires the Building Safety Regulator to keep the safety and standard of buildings under review. As new evidence emerges, updating of Building Regulations or statutory guidance in Approved Documents can then be considered; this includes the electrical safety requirements in Part P of the Building Regulations. Approved Document P refers to the electrical installation standards in BS7671 Requirements for Electrical Installations as the way of showing compliance with Part P requirements. Building owners remain responsible for managing building safety and performance risks of all kinds in a proportionate, risk-based and evidence backed manner.
