My consumer unit keeps tripping, is this connected to the smart meter?

After OVO installed a smart meter it kept tripping. I reported this and was informed to re set the trip. This has gone in now for a year, I turn off all electrical appliances at night and it still trips. Surely this is not right?

If you’re off supply for electricity and can’t get it back on via the fuse board then this may indicate a problem with the meter. Our Support Team will be able to diagnose this for you. You can find more information about emergencies, and what to do when off supply on our website here.

 

If your electricity is off, or is cutting out or tripping, and it isn’t a problem with the meter, then you’ll need to contact an electrician, as OVO only have responsibility for the meter itself, and can’t send an engineer out for any appliance issues.

 

 

 

Update as promised.

I eventually contacted ovo and explained the problem. They said it wasn't the smart meter,  after further discussion he went away to check his computer, whatever he did CU tripped immediately. I told him this and also my problem with gas meter not sending readings. After me checking serial number he told me meter was registered incorrectly and he would update it while I was on the line. Whatever he did, the CU tripped again. I told him and said I was having a new metal cased CU fitted, to which he said he would check back with me to see if this solved the problem.

I have now had the new CU for just under 2 weeks, everything is fine (touch wood).

So I can only conclude it must of been interference,  I think ovo should of informed me about the possible problem with the CU before they fitted the smart meters.

If you have a plastic CU case... do not fit a smart meter, unless you want to spend hundreds of pounds on a new metal case CU.

Thank you waltyboy for your suggestions.

I unplugged everything last night and it still tripped in the early hours.

My electrician has only left the sockets on the rcd to try and narrow it down.

I read on the EV forum a similar problem and they put baking foil round top of smart meter, which blocked the RF. I will try that tonight. The electrician is coming out again.

I will post, if I get to the bottom of it.

Thanks

DO NOT DO THAT UNLESS YOU WANT TO CAUSE A HOUSE FIRE

 

You’re dealing with 240V here - messing with baking foil near an electricity meter may significantly shorten your life expectancy…

For alternative options, please see this thread below:

If that’s not enough to convince you as to why wrapping the meter is a bad idea, this probably will.

Please don’t take that risk...

Oh!

In that case I won't do that.

I will leave it for the electrician. 

Thank you.

Thanks for understanding. Meter wrapping has a 0% chance of fixing anything - it’s a misconception/misinformation issue and at most has a placebo effect. Even the Anti-Smart Meter Brigade has admitted that meter wrapping doesn’t work and tells their followers not to try it!!!

After all, if a Smart Meter could cause trips, so could literally anything else that uses wireless communications! It’s also one of the reasons you shouldn’t just blindly do what Some Guy On The Internet tells you to do without thinking about it.

Thank you. I have contacted the electrician and he will be round in the morning.

Thank you again for the warning.

One thought that occurs to me: Has any part of your house had flooding or is noticeable damp where it could have got into the ring final wiring? The flooding or damp could have happened some time ago and it could be external to the building. I know that the wiring in older buildings can be prone to developing leakage currents even when rewired with modern plastic covered cable and the older wiring materials are very prone to developing low insulation values. Some properties still have the old rubber covered wires and the rubber has gone brittle and just crumbles away 😱

Thanks Peter,

The bungalow is 26 years old. I did have a chimney leak some time ago and had to have the flashing done. 

Would it be the same time every morning? That's why I thought it was the smart meter transmitting.

But I will mention it to the electrician when he comes tomorrow.

Will post when I find out.

Thanks for your thoughts.

Smart Meters transmit pretty much 24/7/365 in one way or another. Unless your RCD is tripping with the same frequency, it’s probably not the meter

It's a mystery, whatever it is.

Thank you.

The timing is a head scratcher for sure. I think we are all intrigued as to what is causing that. You have us beat!
