New smart meter installation- Consumer unit now tripping

When the smart meters were set to communicate with each other, the CU tripped.   The engineer could not solve the problem and simply left the installation without my knowing exactly what the problem was and how ( or who ) was going to solve it.    I am now in limbo !

Any suggestions appreciated.

Similar cases have been discussed in detail in the past on the forum. For example;

 

 

And if you search on Google you will find similar examples. 

 

So getting an electrician to check and potentially try replacing the trips in the consumer unit seems like a good next step to me to see if it resolves the issue.

 

@Tim_OVO i don't know what the general practice is. Should/could the Engineer have aborted the installation and put the old meters back in? I guess it depends on why the meters were replaced

If any appliances aren’t working as they should after a smart meter installation you’ll need to report this to our Support Team. You may need to find a qualified electrician to fix the issue.

… The engineer who installed the SM was from SSE and he knew about RF interfering with the CU.  However, when I talked to OVO they said they had not heard of it before.

I was fascinated by this possibility, so I took to Google. It didn’t take long to unearth this: https://www.electriciansforums.net/threads/rcd-tripping-straight-after-smart-meter-install.200818/post-1783565

 

Interesting that example is SSE as well.

Sounds like a sensitive device to me although the point about cabling is quite valid, especially with the type of device a meter now becomes
