Home charging cable visual check

Check an EV charging cable only after charging has stopped and it has been disconnected in the normal user manner. Look along accessible outer surfaces for cuts, crushing, kinks, bulges, discolouration, exposed material or melting. Any damage, previous repair or abnormal heat means the cable must remain unused for professional assessment or replacement.

Key facts and evidence

For UK home charging, as reviewed on 12 August 2026, the user check is limited to viewing accessible cable surfaces after normal disconnection. The cable should show no cuts, crushing, exposed material, deformation, discolouration or melting. Finding any defect ends the check; it does not authorise handling a suspect area, repair or electrical testing.

Electrical Safety First: Electrical Safety Advice for Electric Vehicles

Inspect the accessible outer surface of an EV charging cable and stop using it when damage, deformation or heat signs are visible.

A condition check only

This page helps decide whether the visible cable condition permits ordinary use. It does not establish electrical integrity or authorise work on a suspect section.

Outcome when damage is found

Once damage, deformation, repair, exposed material or abnormal heat is identified, the cable stays out of use until the supplier or a competent professional resolves it.

What to do next

Use remains conditional on the specified cable having an intact exterior with no damage, deformation, repair or abnormal heat.

Immediate action: Complete the disconnected visual check before the next charging session.

  • A cut, nick, crushed area, kink, bulge or exposed material is visible.
  • The cable shows discolouration, melting, scorching or evidence of a previous repair.
  • Any part feels abnormally hot during normal handling or cannot be disconnected normally.

Checks that stay with this vehicle

  1. End charging and disconnect the cable using the ordinary user procedure for the vehicle and chargepoint.

    The cable is disconnected normally and is available for an external visual check.

    Stop if disconnection is not normal or any part is hot, stuck or visibly damaged.

  2. Look along every accessible outer cable surface without flexing or pressing any suspect area.

    The outer surface is continuous and shows no cut, crushing, kink, bulge or exposed material.

    Stop at the first damaged, deformed or exposed area and leave the cable unused.

  3. Look for discolouration, melted areas, scorching or evidence of a previous repair.

    The cable has an even appearance with no heat damage or repair visible.

    Stop if any discolouration, melting, scorching or repair is present.

Professional hand-off

  • Give the equipment supplier or a registered competent electrician the cable identity and observed defect before replacement or reuse.
