Building Regulations Part P
The electrical safety section of the Building Regulations for England and Wales. Makes any new circuit, consumer unit replacement, and work in special locations (for example bathrooms and kitchens) notifiable. Compliance must be certified either by a competent-person-scheme registered installer (NICEIC, NAPIT, ELECSA), a third-party certifier, or by direct building control notification before work starts. Non-compliant work becomes a legal issue at sale, mortgage and insurance time, not just a technical breach.

The buildwiz build guides walk through a UK extension in sequence and link to Part P (and every other Approved Document) at the exact stage it bites. That is usually a more productive way to use this material than reading the document cover to cover.
