The radial Cooker circuit is already in and the isolator is on the wall (nicely tiled around) to...

    FCU for Extractor fan

    Adding an extractor fan off of a 6A lighting circuit. Installation instructions specify a local isolator (as I would anyway) so 3 pole isolator will be used.

    Shower isolator

    EICR observation - Electric shower does not have an isolator (pull cord or switch). Circuit can be isolated and locked off in the consumer unit which is in the nearby airing cupboard. (This is 1st floor flat). Is there a reg that says a shower should have a local isolator?
