I have a SMETS1 Landis+Gyr smart meter and Trilliant comms hub from British Gas - Can I get an OVO Aclara SMETS 2 smart meter fitted?

Hello,

I have an old British Gas electricity smart meter installed in a cabinet and would appreciate some advice as to whether we have enough space for a SMETS2 smart meter. Hopefully the attached photo will show the current setup.

T

he cabinet is near the ceiling and the bottom of the cabinet is  2.25m from the floor (we receive our electricity supply from an overhead cable).

 

Many thanks for any advice.

Great question to ask about the possibility of changing your current Landis+Gyr SMETS1 (S1) meter.

 

Whilst we do offer an Aclara SMETS2 (S2) meter to customers who have traditional meters installed, we’re not able to offer this if you’ve already got a smart meter installed.

 

Alll S1 meters have been remotely upgraded to communicate with all suppliers,  so a meter replacement shouldn’t be needed to make sure you have all those great smart meter benefits. Read more about this process here.

 

Check out this topic to learn how to read your L+G meter manually, and this guide to submitting the meter readings on your online account or OVO app (download for Android or iOS).

 

Hope this helps!

🤣 not quite - the pipe was fitted around the meter but the absence of black magic makes this a tad dull.

I know, it would be a GDPR nightmare!

That is a good party trick!!

Well, I will admit that your own contributions have also proven useful to us.

Not least the fact you’ve contributed images of British Gas installed S1 L+G meters. Which are actually a LOT harder to acquire than you might expect! Sure, there’s a lot of the pesky things installed all over the country, but not many people actually take snaps of them. Copyright free ones even less so.

I actually have an offer I’d like to make to you though. My own Super User rights here basically gives me the ability to do some extra stuff like having Global Best Answer rights, being able to break through certain anti-abuse mechanisms on the platform and completely bypassing the spam filter (the Super User role is considered a trusted role). I think you could potentially reach it. It’s about time you ranked up anyway, so if you manage to score some Best Answers… You will rank up…

You might want to stick around even after your meters are sorted. Good things may happen if you do. :blush:

Kind of you to say so but my contribution has been at best minimal and limited - if my photos have helped at all I will take this as a positive 😊

I will stick around but with zero knowledge on the meters I think my input will be someone stunted.

Continue to use your Super User role for the good of the community😇

Are you sure about your contributions being… Minimal? :wink:

Muhahahahahaha!

:joy:

If there’s one way to drive traffic to a forum like this one, it’s gotta be talking about L+G stuff.

Trust me, ANY contributions are highly valued - we’re actually planning to open up the scope a bit more too. More news on that master plan soon…

Goodnight!

Thanks for the photo, @Tedbarn. Good to see what we’re working with in terms of space around the gas meter. 

 

As the electricity meter has now been replaced your gas meter won’t be able to complete the enrolment process making it S2 compatible so a meter replacement would be needed to re-gain the Smart functionality. Looking at the photo it does seem to me that the pesky pipe would need moving to allow enough space to fit the type of S2 meters we currently offer, in which case you would need to contact your Gas Transporter to get this arranged. Would be interested to hear if @Transparent would agree...

@Blastoise186 yup still sticking with minimal 😉  The master plan sounds interesting....…

 

@Jess_OVO but does this mean there is still an option in the near future that a smaller S2 meter may be fitted as I was advised by the engineer?

Even with minimal contributions you are raising some excellent points, @Tedbarn!

 

The exact model we are currently fitting is the Flonidan - G4SZV-2 which has the dimensions: 262mm (Height) x 235mm (Width) x 167mm (Depth). As the engineer found, this model doesn’t fit in the space you currently have available. Unfortunately we don’t know if there are plans to offer smaller models in the near future, apologies if the engineer suggested this was the case.

 

However we also work with some third-party installers who may offer different types of meter, if you did want to check this possibility it would be best to contact the Support Team.

Thanks Jess!

I knew my Joker Card would work. I can also grab the dimensions for the other gas meters that are relevant here. The datasheet for the Flonidan SciFlo and UniFlo makes this one easy.

The SciFlo G46UZV-2 and G46UDZV-2 are 103mm H x 224mm W x 135mm D. Which is pretty compact. It’s also pretty light at just 1.2KG.

However, the L+G G370 is not easy to find datasheets for, so I had to go off the Libra G310 instead. That one is 168mm H x 234mm W x 120mm D. Slightly larger than the SciFlo. And heavier too at 2.7KG.

Not sure why though...

Sorry. I disagree. The inlet pipe is the one with the isolation valve handle visible on the right of the photo.

The pipe that runs beneath the existing L&G unit is the outlet from the gas meter. That isn’t the responsibility of the Gas Transporter for your region.

The outlet pipe can be repositioned by a local tradesman who is Gas Safe registered.

That same tradesman should also know the dimensions of a standard gas meter and be able to confirm that it would fit when the pipework is altered…. otherwise I question how he/she comes to be Gas Safe registered in the first place!

From Ovo I am just looking for a bit of consistency with the information provided to me and hopefully a resolution.

It’s been very tricky for the OVO staff to keep their skill-set as wide as possible during the last 15 months of pandemic lockdown. Those in customer services and the Forum Moderators can’t get access to the training rooms and installation specialists who have this level of knowledge.

If we weren’t separated by 100 miles, I’d be dragging @Jess_OVO out on-site whilst some of her colleagues replace meters so she can see the process for herself. She might then learn what Enigma does, for example!

Better still, I’d be putting some tools in her hands and letting her gain some direct experience of handling meters, consumer units, tails and the such-like :wink:
