    Does anyone know if this needs to be the first in line of your circuit? Or if it can just be wired in series with the rest of the detectors

    UK DIY - Reading meter query (see video). Do I have 3 rates?

    Hi. Is there a better forum for this? Anyway I've moved into a new place and the meter is weird. (I just had one physical reading at my old house, but this has loads of "pages" on an LCD). The new place has electric storage radiators (which are currently all turned off at the wall), some of...

    EICR coding question

    Replacing outdoor lamp - wiring query

    Hi, would appreciate some wiring advice in replacing an old outdoor lamp with a Philips Robin 4.5W Wall Lantern with PIR. I believe the previous lamp had an override which meant it could be left permanently on which I'm guessing is why we have 4 wires coming from the house? I'm puzzled how the...

    Failed EICR Query

    Hello all, hoping for a little advice from you kind people :-) My friend has been told to change consumer unit by the people who did the EICR, at a cost of £600, which i think sounds excessive.
