    What does 'mixed lines' mean with regards an EICR?

    A customer has just rang. His daughter lives in Scotland and has just had an EICR carried out. Part of the report says 'mixed lines'.

    JIB Electrotechnical Certification Scheme (ECS) JIB/ECS Phone lines - terrible service nobody answers!

    To be fair (RE: value for money) it isn't actually dear at all. From memory it is roughly £35 for 3 years (if not employed by a JIB member company) for an ECS/JIB card. They obviously deal with a hell of a lot of enquiries and, as I understand it, have only a very small office staff. The JIB's...
