We had a smart electricity meter installed eons (pun intended 😂) ago by a former supplier, and even though it's SMETS1 it has been upgraded and taken over by eonnext, still works with the original IHD from our old supplier, and I can get usage data from it via the Hildebrand Glow API into Home Assistant. It's fab!

However, when the electricity meter was installed we were told that even though the house is relatively recent (built 2003), the gas meter could not be upgraded to a smart meter. Something to do with pipe diameter? Anyway, I would very much like now to investigate again getting a smart gas meter installed – I'm hoping in the meantime they've worked out how to connect the pipes up – but I can't find any info on how to go about doing this.

U16 Smart Gas Meters aren't available yet regardless of supplier. I suspect that's what you need so I'm afraid you'll have to wait a bit longer.

It might be worth posting a photo of your gas meter. This link that might be of interest : https://forum.ovoenergy.com/my-accou...gas-meter-9989

The OVO thread indicated U16 is a high capacity (so large diameter) pipe, which could be reduced to a standard U6 size if your demand didn't require the higher capacity. If that were possible (?) then your gas transporter (network supplier) would have to do the work, preferably on the same day the meter was changed, and even the connection to your pipework the home side of the meter would probably need changing too, perhaps needing yet another engineer to do that .

Even if this is possible and you really wanted to do it, I'd suggest starting to get the dates into diaries for next summer, rather than risk being left without supply in these winter months.

Thanks all. I'd be dubious about changing to a lower capacity meter (at any time of year!) as even if my usage doesn't necessarily warrant a high capacity one now I would assume the original choice of meter was based on the typical consumption for size of house (which I don't think is particularly large, but does have three storeys with a large boiler, so maybe that's the reasoning) and therefore wouldn't want to risk fitting something that could come up on a Home Report as non-standard if we were looking to sell in the future.

Given this link: SMS installs UK’s first ever U16 gas smart meter for Octopus Energy customer | SMS (sms-plc.com) is now over 12 months old I will hold on to the hope that U16 smart meters are nearer today than they were a year ago.

If the required Gas meter is available from Octopus, then one solution must be fairly obvious. But have you actually asked Eon Next to upgrade yet?

The pictured meter looks like a bellows type (used for decades in gas metering) rather than the much smaller electronic flow measurement versions commonly fitted. But that size is probably what you already have.

The suppliers who do install U16 gas meters usually charge for an additional site survey (British Gas, for example, charge £102). A U16 meter is twice the size of a U6 as they contain two sets of measuring bellows rather than a single set. The actual pipe diameter is usually the same.

The most common model is the Flonidan Uniflo G10SDZ-2 and also the best as it is dual band and conforms to v3 of the SMETS2 standard.
