Bathroom lights

Posted by Paul Johnson, on
The lights in the bathroom have started to flicker and then go out and back on again a short time later. The switch is a pull cord. Is it likely to be a poor connection or something more serious? Is the fact that we had solar panels fitted a few months ago a likely cause - someone brushing against the wiring in the loft space?

The common cause of flickering lights that also go out and come back on is a loose connection. If it is only at one light check connection at light fitting and switch (with circuit off and circuit tested to be dead) if it is more than one light check the neutrals of the circuit and the loop ( permanent live) which will be at the switches or light fittings, depending how it was wired. The solar should not effect your lighting at all, this just generates and meters electricity. If you are still having problems I am on Rated people under Great British Electrical, feel free to look me up and give me a call . Best regards, Gary Worgan (NicEiC.Jib)

Paul, As you have seen in the respones you already have to your question it may well be faulty connections but to be honest I doubt it could be so simple. One other scinario that is possible........ IF your lighting is low voltage downlights it may well be transformer problems causing flickering...I doubt if the installation of solar panels has effected your lighting.....to be honest to be safe you should have an accredited electrician inspect them, go for a member of NICIEC in England or SELEC if your in Scotland.

Hi Paul From your description it sounds likely to be a loose connection that is causing your lights to flicker. The switch is a good place to start if all the lights are flickering together. Also there could be a junction box installed somewhere in the circuit (likely to be in the loft) which would be another good place to start. A loose connection can be a serious problem as it causes a build up of heat. Paul please remember to isolate the lighting circuit at the consumer unit when removing any covers that expose live parts.

Hi Paul, Lights flickering can be Down to a few issues,loose connections at the pull switch or where the connections are made at the light fittings themselves,also if you have extra low voltage lights in bathroom it can be the transformer,would suggest you get a qualified electrician to check the circuit,Aldo check if there was any ingress of water since the panels have fitted Regards Rory RB Electrical

Sounds like a poor connection, you could try tightening the connections in the light fitting and switch (please remember to isolate the power supply). If your not comfortable doing this get an electrician in.

It is likely you have a loose connection (probably nuetral) at the light switch or at the ceiling rose If bathroom lighs are extra low voltage then there could be a transformer problem, it could be the contacts within the light switch itself I would post the job get a qualified electrician in to have a look

Hi Paul, Lights flickering is usually down to a couple of issues, poor connections, poor fittings or poor bulbs. Unfortunately the only normal way to determine the fault is to check/replace all three. The only other possibility is you have had water ingress from the roof since the solar panels have been fitted, although this means you would have to check the loft for moisture or wetness. I can take a good electrician less than an hour to diagnose the fault and repair it, however this is a job a budding DIY could undertake as well, with nothing more than a multimeter. Please remember to disconnect all power when working on electrical wiring & fittings and if unsure at any time call a professional. Kind regards, Matt Elcert

If all the lights flicker it is likely to be the switch or the first connection. If the lights are Extra Low Voltage there could be a problem with the transformer. Regards, David.
