Asked by Sir James CleverlyConservativeMinistry of Housing, Communities and Local GovernmentTabled Answered 20 April 2026UIN 124800

The question

To ask the Secretary of State for Housing, Communities and Local Government, with reference to the DESNZ press release, Government to make “plug-in solar” available within months, of 24 March 2026, whether householders will be required to hire a certified electrician to connect to the main electricity supply and comply with BS 7671 UK Wiring Regulations; and whether building regulations will apply to the installation.

Answered by Samantha Dixon

Part P of the Building Regulations 2010 and Approved Document P make clear electrical installations in dwellings should be designed and installed in such a way to protect people from electric shock and fire hazards. Approved Document P refers to the electrical installation standards in BS7671 as the way of showing compliance with Building Regulations. In domestic situations, if electrical work is notifiable, competent electricians can self-certify that their work is compliant with Part P of the Building Regulations. All electricians who have been authorised by a government approved Competent Person Scheme are listed on the Registered Competent Person Electrical Register All other functional requirements of Building Regulations, beyond electrical safety, must also be met.
