Hello, I am not an electrician. I don't normally post on forums but I'm at breaking point with this situation and require some advice please.

Our new shower was installed earlier this year. Since it was installed when you press the new shower on the ceiling light in the bathroom flickers (strobe like) as does the ceiling lights on the landing and small bedroom (all on the right side of the house.)

No other lights flicker when the shower is on anywhere in the house and the bathroom light doesn't flicker at any other time when it is on (only when the shower is on.) We have changed the light bulb in bathroom and it's still flickering only when the shower is on.

When the shower is turned off the flickering stops immediately, however, the shower is on one consumer board and all ceiling lights are on a separate consumer board. We have been told the cable is correct for the connection of the shower.

With the old shower there was only a small dip in the ceiling light when it was turned on similar to when we put on our hoover and our downstairs table lamp dips in light once. We have been told this dip (or blink) of light is normal due to the load it uses.

We use a 25watt incandescent bulb in the bathroom. We use these bulbs as a family member has seizures to LED and fluorescent lights and can't use any other bulbs. We are aware they are no longer available to buy.

I've had 3 electricians out and also the local electric board to test equipment and they are sending us round in circles (electrician says everything is working normal and it's a supply issue and supply says it's a electricians issue as there are no supply faults.) Our meter doesn't reflect any issues so the electric supplier won't send any one out to look at their equipment other than the replace the existing meter.

We need to have a new hob and oven installed and the electrician has said we can't do that until we find what is causing the flickering issue, however, the electrician has said he cannot find the issue even though the flickering is visible and he has seen it. He has told us to keep a diary of when the flickering occurs (but it is only when the shower is turned on that it happens.)

The shower company cannot help us with this as they are only for installing and repairs even though we have told them it started when the new shower was installed.

Can anyone advise what I need to be either doing or asking because I'm at a loss on what to do and just want to get the house back to our normality again. I am not going to do any work on this as I am not an electrician.

Many thanks for your time with my query.
 
I'd be looking for a loose neutral ....................if it didn't do it before the shower was fitted, on the shower circuit or fuseboard.

I don't see why this issue is holding up fitting a new hob and oven.

Hi Murdoch, Many thanks for your reply.

Would there be any reason why it's happening considering they are on separate consumer boards?

The reason for the hob/oven was the electrician told us that we couldn't change anything until we found out what causing the flickering.

Again, with thanks.
 
Hi showerq,
I would not advise you to look for the loose neutral. I would get the spark back who fitted the shower.

Cheers

Hi Paignton pete, Many thanks for your reply.

I will not be touching anything, however, the shower company who installed it are refusing to comment or do anything about the ceiling lights flickering which only started when they installed the shower.

We cannot get an electrician to help us until we find out what is causing the flickering and the electric supplier and electric board won't help either.
 
Hi - question from left field - are these led lights that are flickering? If so, can you swop one for an old fashioned incandescent lamp and report?
Edit - oops - just read that they're 25W incandescent. End of that thought.
 
Did they leave any certification when they fitted the shower?

Do you have a split board?( does it have a main switch and 2 rcd's?)
If so is the light circuit that's flickering on the same rcd as the shower?

As for you cannot get the electrician to return untill you know what's causing the flickering. You cannot know what's causing the flickering until you get the electrician.

Go back to the installation company and insist they return or contact there registration body. They will insist they return.

Cheers
 
It could well be a loose neutral or live and could even be at the service head or meter, which could be why an electrician cannot find it. Sadly the service head is managed by one company, the meter by another and after the meter its an electrician. If it was my house i would have checked all connections at the meter and service head but sadly that breaks a number of rules in the industry which could have un-desireable outcomes for whoever does it.
If the electrician has checked all connections from shower to board and all connections between boards, a meter man has to check the 4 connections on his meter and then the local network supplier has to check his connections in the service head, thats the correct method.
Good Luck
 
One other point I must make. It may be that the flickering lights have absolutely nothing to do with the work on the shower.

It may be a total coincidence.

If the company do return and find this you will be liable to pay for any works.

I'm just trying to look at this from both perspectives.

However I do think the company should have returned to check this out of common courtesy and customer service.

Cheers

I would go with the possibility there's something wrong with the supply.

Have your supply company etc, got their tools out and checked their equipement?
