Who is responsible for moving meter cables?

I have to say that I disagree with the report from SSEN. 
The main cable from their cable incomer goes directly into that earth block (it’s actually an N/E - Neutral Earth connection) and as such is before the meter, not after it. 
 

It may be one of these tricky situations where SSEN and OVO have to make a joint appointment as I can see that the earth disconnection would be a problem for the installation even though it is before the meter

Thanks for your help. One thing I don’t understand is why have I had 2 smart meters installed on exactly the same cable set up before? They were removed later because they weren’t communicating 

If you are talking about 2 previous versions and wondering why more space is needed, the newer smart meters are slightly larger (they do vary) 

UPDATE 

So after months of trying to get this sorted I have now come to a deal end. The OVO engineer was booked for the 18th of December. Despite the complaints team having photos of the meter in advance the engineer still attended and immediately said he couldn’t do anything due to the earth cable. I then contacted SSEN who now say they could do a meter block whatever that is but not just now (?). Or I could get a special electrician to move the cable. As according to SSEN the cable is not faulty they will not be prepared to move it. I simply don’t have the money to be able to get specialist electricians to do the work. The housing authority do not have the ability to do the work and will also not do it because the wiring is not faulty. 
 

The meter was functioning perfectly until OVO did a key overwrite for a missed engineer appointment and OVO had started taking money from the meter for a wrongly billed amount without telling me. Also I was getting a smart meter because OVO pursued me for months telling me I would get a large bill if I didn’t get one (I have a key meter) eventually agreed I do have a key meter then sent me a large bill anyway. Then sent another larger bill last week. 
 

I have emailed OVO but they are now ignoring me. 
 

I have considered moving supplier as a last resort but I am thinking I might run into the same problem again with the cable. 
 

Ideas?
 

Changing supplier will NOT fix this because it very much looks like SSEN needs to do the work. This is not an OVO problem and no supplier under the sun can do this particular job.

I will ask ​@Lukepeniket_OVO for his opinion, however there will be caveats:

• It’s the 23rd December and 99% of OVO is closed right now - I can’t guarantee Luke being around or able to reply until the New Year
• Luke’s advice is probably the absolute best we can do here on the Forum - if he can’t help, I’m afraid we can’t advise further
• It’s Christmas Eve tomorrow, so no promises can be made about who’s around to action anything

Thank you Blastoise186. It’s very much looking like I’m stuck with this now. I had decided to leave it before when my economy 7 was working correctly but stupidly didn’t realise that a key overwrite was going to cause the malfunction. The main problem is that because of this my immersion water heater costs a fortune to run now because of this because it doesn’t work with the economy 7 time switch and neither does my heating. 

Heres the response from SSEN. :Looking at the notice given by OVO it is an electrician you need as they will be able to advise on the best way to move the earth connection so it is not interfering with the meter change.  

We can provide an earthing block at our cut out side (before the meter) but wouldn't do this at the moment as you have a current earthing arrangement that is potentially sufficient.

If you get a SELECT or NICEIC electrician to your property they should be able to let you know how it is meant to be installed.

Like I said I’m not prepared or able to pay for an electrician. 
This has wasted so much time and caused a huge amount of stress. 

And unfortunately, it’s just another reason why I hate Trad Prepay Meters - it’s almost impossible to get things done quickly with them regardless of supplier...

Hey ​@Flora48 

I’m sorry you’ve had such a negative experience.

I can see our community members have already provided helpful advice here. I just wanted to add the following topics which may be helpful:

 

Update 

Last week the earth cable was moved by an electrician and on Wednesday OVO came to install the smart meter. However I had to leave for work before it was finished and left someone else to be in the house. When I got home I discovered the smart meter was not connected and there was no tariff showing on the main meter . I phoned OVO and after a few minutes from the end of the call they phoned back to say they would have to send an engineer again. 
This is exactly what I thought would happen once I got a smart meter because I had 2 previous meters which were eventually replaced with the key meter that was removed because they wouldn’t connect. This was when it was SSE. At the time it took a lengthy complaint procedure and at the end I was told by SSE that rural properties like mine are unsuitable for smart meters.
