Landis+Gyr E470 smart meters - your guide


One of the great things with smart meters, is that there’s quite a good range of options out there for suppliers to pick from. I’m quite a fan of the Aclara SGM1300 and SGM1400 Series myself, as I think they’re really nice and easy to live with. But there’s a bunch of others too…


One of the most common meter brands used in the UK, is Landis+Gyr (L+G). They’ve also been a very common brand in the UK for many years, and it used to be highly likely that at least one electric and/or gas meter in every street was an L+G model, and this continues with smart meters. But there is also a bit of an unfortunate - and somewhat unlucky - snag here. How does one tell a SMETS1 Landis+Gyr smart meter apart from a SMETS2 Landis+Gyr smart meter, when they apparently all just so happen to be the Landis+Gyr E470 and G370?


On top of that… Can you even switch supplier and if so, would you even know if your smart meters would suddenly drop off the grid and go ‘dumb’? :open_mouth:


Don’t worry, your resident Master Blaster has some tips and advice. :sunglasses:


What does a SMETS1 Landis+Gyr E470 look like?


Here’s an example of one installed by British Gas/Centrica:

As an alternative angle, this is another image from the same thread:

The images above were originally posted in the thread below, which has some useful discussions.



The most common characteristics of the SMETS1 versions are the fact they have a black border surrounding the display, and will often have a separate Comms Hub next to the meter, such as the Trilliant SEAP-2001-V. If you have one of these, your gas meter will also be SMETS1 and is probably a Landis+Gyr G370.


If I’ve got one of these, can I switch supplier without breaking it?


Unfortunately, I’ve got a bit of bad news there. To get the best info, I need to call in help from SmartMe, one of the resources we use here a lot.


While the plan is to upgrade as many SMETS1 smart meters as possible to SMETS2 firmware and migrate them to the National Smart Meter Network via the Data Communications Company (DCC), it’s running a bit behind schedule at the time of writing.


The latest details we have are that S1 L+G meters are planned to be migrated around Autumn to Winter 2021, but this may still change. If you’ve change supplier in the meantime and your meter went dumb, it should recover after this process completes.


I’m with British Gas right now and they installed the meter, is that a problem?


I’m really sorry to say that due to the fact British Gas/Centrica are using their own proprietary WAN that no other supplier can access, if you switch away from them now, your smart meter will almost certainly go dumb temporarily. Don’t let this put you off though! It simply means you’ll just have to put manual readings in for a bit.


If the meters were installed by another supplier and are still SMETS1, they might still work fine with a few suppliers. Please check first!


All of these meters are being included in the migration. Once DCC takes over control, British Gas won’t be involved anymore and your meters will work fine everywhere.


Will these meters work with OVO?


Not yet, but they will soon! OVO chose to go with Secure branded meters rather than L+G back in the SMETS1 days, so the only SMETS1 meters OVO can support are those from Secure. However, OVO has got full support for all SMETS2 meters and SMETS1 meters from any brand that have been upgraded to SMETS2 and migrated to DCC. My own Aclara SGM1311 (guide here) that I like to call Raichu is one such meter.


Feel free to switch to OVO anyway if you wish. Once the meter starts working, you’ll be notified.


What does a SMETS2 Landis+Gyr E470 look like?


Good question! Here’s an example of one that was originally installed by EDF:

Pretty much all SMETS2 L+G E470 meters look a bit like this one, but might not have the supplier stickers. They never have a black border around the display, and will always have one green and one grey button - but might not be in the same places.


If you have one of these meters, the exact gas meter you have may vary.


Will these meters work with any supplier?


Yup! As the SMETS2 variant, these ones work freely with any supplier, even if you’re no longer with the one that installed the meters.


So why the same model number?


That is a mystery we’ve yet to solve. Sorry! Perhaps L+G might tell you a few clues though. :wink:


I’m still confused about what I’ve got, can you help me figure this out?


Sure! Feel free to reply on this thread with some photos of your meters and IHD if possible. Even if you’re not with OVO, we’re always happy to puzzle solve for everyone. Not got a forum account yet? Click here to create one!

I think this is a popular question for UK households with this meter manufacturer type. Thanks for helping them know what they’ve got on the wall, @Blastoise186


Oh and if you’re seeing this and happen to be designing meter names, makes and models, maybe consider making the name of different versions a bit different? :joy:

Definitely agreed there!

I much prefer it when a new model either gets a new model name/number that’s unique for the manufacturer and can be easily identified as being that particular one. At very least, if a model name/number is going to be re-used, it’s appreciated if it’s at least clearly marked in a way that makes it easier to tell apart. So for example, if the S1 L+G E470 meters were marketed, sold and clearly labelled/marked as something like Landis+Gyr E470 Series 1, or Landis+Gyr E470 v1, that would have made it a bit easier to identify. Likewise, it would have been nice if the S2 variants were clearly shown as something like Landis+Gyr E470 Series 2 or Landis+Gyr E470 v2. While not quite as ideal as a completely separate model number, it does at least provide something I can work with as a user.

I very much prefer the way Aclara does it for example. If you’ve got an Aclara SGM1300 Series meter, such as the Aclara SGM1311 Smart Energy Meter with an Aclara SGC1311 Smart Communications Hub, that’s really easy to identify as being SMETS1 hardware - however many of these ones have now being upgraded to SMETS2 firmware and are currently being migrated to DCC.

Likewise, if you’ve got an Aclara SGM1400 Series meter, such as the Aclara SGM1412-B, these are definitely SMETS2 all the way through. It also helps to reduce confusion.
