What Is a C1 Code on an EICR?
C1 – Danger Present (Immediate Risk)
C1 – Danger Present indicates an immediate risk of electric shock or fire within the electrical installation. This classification is reserved for serious faults that require urgent attention by a qualified electrician. Examples include exposed live parts that are accessible to touch, conductive parts that have become live due to a fault, incorrectly wired circuits, or badly damaged accessories. Any C1 observation means the installation is unsafe and requires immediate action to protect both property and occupants. For professional assistance, see our EICR inspection service.
A C1 code will always result in an unsatisfactory EICR. The electrician should not leave the installation in a dangerous condition and will usually take steps to make it safe before leaving.
Common examples of C1 observations include:
• Exposed live parts that are accessible to touch, such as:
• A fuse carrier or circuit-breaker missing from a consumer unit with no blanking piece fitted
• Terminations or connections with no (or damaged) barriers or enclosures
• Live conductors with no (or damaged) insulation
• A badly damaged accessory (e.g., socket or switch)
• Conductive parts that have become live as the result of a fault
• Incorrect polarity
Important Safety Notice
