Consumer unit replacement is classified as notifiable work under Part P of the Building Regulations in England and Wales. In Birmingham, this means the work must either be carried out by an electrician registered with a competent person scheme — such as NICEIC, NAPIT, or ELECSA — or the homeowner must notify Birmingham City Council's Building Control department before the work starts.
Regulation 421.1.201 of BS 7671 confirms that an Electrical Installation Certificate (EIC) must be issued for consumer unit replacements. The EIC documents the design, construction, inspection, and testing of the installation. A registered electrician will self-certify the work and submit notification to Birmingham City Council through their scheme provider.
If you use a non-registered electrician, you will need to apply to Birmingham City Council's Building Control for inspection before work begins — this typically costs £150 to £300 and involves delays. Using a registered electrician avoids this process entirely and is strongly recommended.
You should receive a copy of the EIC and a Building Regulations Compliance Certificate within 30 days of the work being completed. Keep these documents — they are required when selling the property.
