How will SMETS1 meters be updated when SMETS2 is rolled out?

In your discussion on SMETS1 vs SMETS2 you indicate that SMETS1 meters will be made DCC compliant by end 2019 but you do not make it clear if this will be a hardware fix done by an engineer at the house or a remotely activated software download. (I mean in respect of the meters you are currently installing).

The Smart Data Communications Company  (DDC) upgrade of S1 meters is carried out remotely. The info below was taken from this topic guide we made to explain this process of upgrading S1 smart meters: 
 

Getting your S1 smart meter onto DCC - your guide

 

When you switch suppliers with S1 meters, we can't always communicate with your meters. Take a look at S1 meters we can communicate with for more information. 

What is this update?


It's a nationwide update to S1 meters to make them automatically send readings if they had stopped communicating due to a change of supplier. The process it goes through is Enrollment & Adoption (E&A), the output of this means both S1 and S2 meters are controlled/managed by the DCC.


Why do these smart meters need to be updated?


To get the full benefits of smart meters, the government has decided that there should be one new unified smart meter data network. This makes smart meters work more effectively with all energy suppliers, improving the efficiency of the grid and helping us all to cut carbon emissions.

Once your S1 smart meter has been updated to this single network, you’ll also be able to switch suppliers without your meter losing its smart features. Smart meters automatically send meter readings to your energy supplier. This means your bills are more accurate, and you can see how much energy you’re using your online account or OVO app (download for Android or iOS) – It’s also shown on your In-Home Display (IHD)

Until your meters have fully gone through the E&A process, they will become dormant. Therefore, you’ll need to provide readings to make sure you receive accurate bills. 

What timescales to expect for my meters to be enrolled?


This table shows the expected delivery date depending on the Meter Manufacturer. 
 

Meter Manufacturer MSN format Fuel Expected migration to Smart
Secure YYP Electric Started January 2021. Expected to complete by March 2022.
  G4P Gas  
Elster YYK Electric Already started. Planned completion October 2021.
  G4K Gas  
Aclara YYM Electric Already started. Planned completion October 2021.
  G4F Gas  
Itron YYS Electric Already started. Planned completion October 2021.
  G4 Gas  
L+G YYL Electric Started May 2021. Expected completion September 2022.
  ZYYQ Electric  
  ZYYN Electric  
  E6S Gas  


How can I easily identify if the meter is Secure?


Secure Electric Meter Serial Numbers will start with XXP (eg 18P) and Gas Meter Serial Numbers will start with G4P.

These are the only circumstances which you’d normally get charged to replace a meter:

  • Vandalism/deliberate damage e.g. you ripped the meter off the wall and smashed it to pieces
  • Supply/Meter Tampering/Energy Theft/Abstracting Electricity/Gas - you would ALSO be liable for paying back all the energy you stole in the meantime, paying back every single cost the energy supplier incurred to investigate you, every cost incurred in undoing the damage you did and probably a bunch of other stuff too… And potentially also land yourself a criminal record
  • Swapping between Single-Phase and Three-Phase
  • Meters fitted under warrant - Suppliers can potentially charge you the costs of doing so
  • Non-Standard Installations - Usually triggered in cases where you insist on the supplier NOT fitting smart meters and forcing them to fit something else they don’t want to use

There’s a couple of others as well, but they’re edge cases which most people won’t realistically encounter

Hello,

Thank You for replying.  The engineer said if it failed the first time and was successful the second time, it probably wasn't and it was useless trying to upgrade old teqnology, so she will still get a new Smets 2 meter fitted without charge.  I only ask because she is anxious as I read they charge for a new meter swap even if faulty which doesn't seem right as it's not the customers fault.  My sister's Smart meter stopped sending readings to British Gas  last year.  She didn't realise they never informed her.  The meter was about 10 years old and was replaced free.

Yeah, I’ve seen this situation before. Getting it replaced is free as it’s considered a faulty meter - and most importantly - the root cause has been determined to be something that’s beyond your control.

If you smashed it up with a baseball bat however… Then you would be liable to cough up the cash as that would be vandalism.
