Electrical certificates after home improvements: what to ask for
Understand the paperwork to request when electrical installations are altered or replaced.
Applies to: Primarily England; the notification route and required documents depend on the work.
Last checked: 16 October 2026
Key points
• Electrical safety certificates and Building Regulations notifications are not the same document.
• Some installation work is notifiable; a competent-person installer can self-certify qualifying work.
• Keep paperwork linked to the correct property and work description.

Why it matters
Moving a socket, installing a new circuit and replacing a consumer unit are not identical jobs. Ask the electrician to explain what testing and certificates apply to the work actually carried out.
Checklist before you start
• Confirm who will carry out the work and whether the person is appropriately competent.
• Ask which installation or minor-works certificate will be issued as appropriate.
• For notifiable work, confirm the Building Regulations compliance route.
• Store certificates and test results with the job and property records.
What to do next
Do not accept verbal assurances in place of promised documents. If paperwork is missing, raise it with the installer or the relevant scheme or building control body.
