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).

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 online – or 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.|
|Elster||YYK||Electric||Already started. Planned completion October 2021.|
|Aclara||YYM||Electric||Already started. Planned completion October 2021.|
|Itron||YYS||Electric||Already started. Planned completion October 2021.|
|L+G||YYL||Electric||Started May 2021. Expected completion September 2022.|
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.
