Lights flickering throughout flat since Smart Meter installation

Hi there,

 

I had a smart meter installed about a month ago. In the last couple of weeks the lights in the apartment have started flickering, particularly when power-hungry devices (e.g. kettle, microwave) are used. Over the last week or so this has got worse, and now occurs even when no appliances are in use. 

An electrician came today and couldn’t find any potential causes, but isn’t allowed to look inside the smart meter because it’s property of OVO. I contacted OVO this afternoon and they’re not able to send anyone out to resolve this worsening issue for the next 3.5 weeks. 

 

Is this issue common with smart meters? Are there any potential solutions to this in the short term?

Many thanks!

Hi @jacobdavies if it is just light flickering (rather than power sockets and appliances) it will not be caused by the smart meter.

 

Lights will be on a different circuit and it is that circuit which is more likely to be the cause. You mention an electrician taking a look - unfortunately an intermittent fault like you describe is very difficult to detect but if there is poor wiring in and around the main distribution board, that is where to start. It could be that something was disturbed when the swap was made

 

Issues with household appliances, such as flickering lights, will need to be reported to an electrician. You can find electricians in your area here.

Hi @jacobdavies ,

This is unlikely to be the smart meter itself, but OVO can definitely take a look for you. It’s more likely to be a badly installed meter - smart or not - than an actually faulty meter. And even then, a fault like this could happen to anything. Either way, it’s very rare that this comes up.

My guess is bad wiring somewhere, but @PeterR1947 probably has a better chance at figuring this out than I do.

Hi @Blastoise186 ,

Thanks very much for your reply.

I understand from here (under ‘Noisy Electricity Meters) that OVO would be able to come out sooner if my meter was making an arcing, vibrating or zapping noise - then I could book in an emergency meter exchange. However, although I have evidence of bad wiring at or around the meter, I don’t qualify for an emergency visit - is that correct? Is it worth me calling the number on that page anyway?

Many thanks!

I wouldn’t usually automatically jump straight to an EMEX, because that might not solve the real problem. It’d probably be better to have OVO send an engineer out to check the existing equipment is installed properly first.

What you describe doesn’t sound like it qualifies for an EMEX either...

Hi @Blastoise186 and @BPLightlog ,

Thanks for your speedy responses!

It is both lights and appliances flickering (the microwave light now flickers quite a lot, and didn’t before). The electrician wasn’t able to find any potential causes outside of the smart meter - that was the only stone he had to leave unturned.

It sounds, then, like I won’t be able to get this resolved until the OVO engineer visits in late January. Is there anything I can do at my end to dig deeper into the issue, or to get an engineer to visit sooner?

Many thanks!

The problem if it is caused by source at or near the meter is that there is so much energy and so it is not the place to ‘take a look’. 
If you can show the engineer what’s happening easily, they should be able to sort things. It does sound like a loose connection unless it is an unusual faulty meter

Hi @BPLightlog ,

Thanks for this! Just to clarify - do you mean that I should call out the electrician to check again for an external loose connection of the smart meter, or should I sit tight until the OVO engineer comes in late Jan?

Many thanks!

If lights and other appliances are affected it certainly sounds like a loose wire somewhere and as the only change has been the smart meter fitting the finger points to that.  Are there any signs of discoloured insulation around the meter tails going into or out of the meter?  If there is any discolouration, this is an emergency.

@jacobdavies as Peter says, look for any discolouration on the wires connected to the meter. Another clue might be if you can see any flashes by the meter connections. Can you look at the area easily in the dark? (Don’t put yourself too close, just in case)

Hi @PeterR1947 and @BPLightlog ,

Thanks so much for your responses, especially on New Year’s Eve!

I just put the kettle on and had a look at the meter in the dark and couldn’t see any flashes. However, I could hear occasional tinny ‘dzzt dzzzzt...dzzt’ sounds from it, almost like a sparking sound. Might this be arcing?

Below are photos of the meter. The only potential discolouration I could see is on the right-hand one of the white cables going into the base of the box marked Scottish Power only. This is clearly an older cable though, so might have been like that for a long time.

Many thanks!
