Lights are occasionally flickering

Posted by Ian Addison, on
I have just bought a house that I intend to rent out. i am spending every evening working on it and i have noticed that the lights occasionally flicker. It happens on both the upstairs and downstairs circuits. Some evenings I have noticed that the lights do not flicker at all. The house has only recently been rewired this year. It is all very confusing, does any one have any idea as to what it might be?

Hi Ian This sounds like its a loose connection somewhere. If all the lights are being affected at the same time a good place to start looking would be the consumer unit. If two circuits are being affected it will be something common to them both. I do not recommend removing the cover from a consumer unit unless you know what you are doing.

If the lights are on two Seperate circuits then the problem may be in fact two Seperate causes. The more likely explanation though if all lights flicker simultaneously would be loose connections within the consumer unit. Either way the contractors who carried out the Rewire should come out investigate and rectify the issue. There is only one exception to who should carry out the remedial work and that is if you have changed any light fixtures in whch case i would look at those items first. Kind regards, Matt Elcert

The main reason for flicking lights is the voltage drop It can by by poor connection in circuit, or dimmer switch or bulb. I had such cases, there is need to check all the rules. Chris

Hi as previous comments have suggested could be poor connections. Or it may be you are near the end of a long run of cable coming from the dno, electricity networks. Also If it is in the evening everyone else who share the same phase as you are consuming a lot of electricity. It would be advisable to have an electrician come in and test your incoming voltage and see what it is and if it is fluctuating up and down. Many thanks Darren Gotts Electrician.

From what you have described it sounds like you have a loose connection(s) on that part of the circuit. Continuity reading will Confirm this but again it could be something else. Post job on this site and get a qualified electrician to come out and have a look

Hi Ian, I would request you to check all the neutral connection for the lights, I would strongly recommend you to start from the fuse board and work towards the lights. If you can still have this problem please come back and let us know. Thank you for coming on board.

Most likely a loose neutral connection on the lighting circuit. In my experience I have found a loose connection on the ceiling rose where the lights are connected.
