    Hi.

    Whenever anything electical in our house is switched on or used the lights throughout the house flicker slightly.

    Was wondering if there is possibly an issue with wiring or breakers or if this is common.

    Does anyone know if this can be stopped

    Many thanks

    When you say "anything", what would they be thats getting switched on? It would not be unusual to see a very slight flicker just when a heavy load is switched on, such as an instant shower. The lights get very slightly dimmer due to the heavy load on the cable supplying the house, and go back up again when the load is switched off.

    This would be more noticable on older networks such as overhead lines outside supplying the house.

    If its a continuous flickering after something is switched on, then there is a problem at or before the consumer unit alright.

    It is very common for circuits in a house to be (err) amended and added to without taking into account the loads at the consumer unit or on the incoming supply.

    Many houses are classic examples with the number of sockets being doubled or tripled in many rooms without considering the old consumer unit. Worse case I've seen was the replacement of a din rail transformer for a bell with a 16 amp MCB for an extension on a consumer unit that was already well loaded.

    So get someone in to check the loading on your circuits, the consumer unit and the rating of the incoming supply.

    I'm with Robbie on this as my house lights dim slightly when our Triton electric shower is switched on and they get bright again when it gets switched off.

    Apart from that I've had no electrical problems in my 4 year old new build (with the exception of a fused immersion heater, fused shower switch, fused cooker switch, plug wiring coming loose, light switch wiring coming loose, heating timer fusing etc etc etc). Good job he was an ECSSA certified electrician or I would have been in real trouble:rolleyes:. And yes I'm being sarcastic as all they advised was contact the electrician to sort our your problems and guess what, he wouldn't answer his phone. Oh I love this self regulation we have in this country.
