After smart meter installation - Off Peak storage heaters tripping lights, appliances etc.

My smart meter was fitted on 31/05/2024.  I never had a problem with my electricity before then.

My off peak storage heaters were off for the summer.  My immersion heater was still in use. It is on Off Peak tariff & has a Horstman Timer (it comes on between (3 am & 6 am). It is still in use & never been a problem. The immersion heater night rate KW hours are showing on meter readings on my account.

In early October, I put on the storage heating.  

When the off peak for the storage heaters came on at about 12.10 B.S.T. - It tripped all the lights, appliances, TV etc. in the house.

The consumer box could not be reset to turn Lights, appliances etc., until the storage heaters were switched off at the switches in each room.

My electrician has tested my electric system fully over days & weeks and still there is a problem.  His belief is there is a problem with the meter either a switch  or wiring in the meter.

I keep getting fobbed off by customer services & they have asked me to get a plumber to look at the Immersion heater.

I am now 99% certain the metering installation is wired wrong, I've zoomed in. 

 

Black cable far right looks like a neutral which is connected to the 5th terminal... I believe that black cable should be in the neutral block and the small red cable for left should be moved to fsr right hand side.

 

Surely some sort of emergency visit due to no heating or hot water needs to happen??? 

 

Are you on Facebook? I would search for thr group 'Facebook group energy support and advice UK' and find the admin Gemma Hatvani. 

 

Basically she's a god, she's unaffiliated with any supplier but has a hotline to most of then to get issues sorted out!! Saves waiting 3 more weeks for supplier and then going to Ofgem, worth a go.

@Giffy in your meter cupboard is there any more properties with an arrangement similar to what you had?

Perhaps one. It has a different meter from the one I had. My meter was very small and showed daytime, nighttime & total of both. Everyone has been changing to single tariff.

Thanks

All similar set ups that I’ve seen have had a 100mA RCCD/RCBO as a main feed with if needed, 30mA units on individual circuits - I would still suggest that 30mA is too low for use for the whole installation. 
Note that these storage heaters have been off during summer and so could have additional leakage until heated.

It looks like on the photo of the brown and blue blocks that both left hand blocks only have 1 cable in them?

 

It does look like the Engineer hasn't wired it up correctly if I'm honest. There should be multiple cables in the neutral block for both 24hour and off peak supplies, I'm unsure if the neutral has been wired to the 5th terminal block (far right). If we've had no luck with supplier I believe it's now time, if not done already, to open a complaint with them.

Its now about 5 weeks since I first contacted them. I have raised a complaint, but have to wait 8 weeks for ofgem.

Could you tell me how to proceed?

@Lukepeniket_OVO  , I am not on Facebook, however,  I will be on the phone first thing tomorrow & I will let you know how I get on.

Also, apart from the shower, my immerser is working.

Thank you for your help.

It’s hard to advise as you’re with a different supplier ​@Giffy. Do you have a contact in the complaints team like a complaint handler you can reach out to?

 

I hope you got on okay!

An OVO engineer came to install an electric smart meter earlier today. In doing it appears he has cut off the electricity supply to my gas boiler. I now have no heating or hot water. It is now 9pm. I called OVO at 4.15pm to be told an engineer would be out with in 3-4 hours. Is it likely that anyone will come out now

Hey ​@tinx,

 

I’m sorry you’ve had issues with your boiler since the meter replacement. I just have a few questions to give us a better idea of what’s happening.

 

Have you looked at the fusebox to make sure that none of the fuses are tripped?

Has anything else been affected or has it just been the boiler? 

Is there any power to the boiler at all as there should be a mains switch at your boiler you can try turning off and on again?

 

If you can let us know the answers to the above.
