FAQs

  • A consumer unit (fuse box) distributes power into circuits and protects against overloads and earth faults through circuit breakers and RCDs.

  • New consumer units trip faster, meet current safety standards, provide better circuit separation, and often include surge protection.

  • Yes. We handle Part P notification and supply a fully compliant Electrical Installation Certificate.

  • If your cables meet BS 7671 condition and sizing requirements, they can often be reused. We’ll confirm this during the survey.

  • An RCD is a Residual Current Device. In simple terms it trips when it detects that electricity is flowing down an unintended path like a person or through metal casing. It trips quicker than a fuse reducing the risk of an electric shock or fire caused by earth faults.
