Smart Meter (gas) not working

TOPSie2

A few years ago my energy supplier was Shell. Whilst with them I had smart meters (both gas and electric) installed. Shell gave all their business to Octopus. I rarely look at the smart meter gadget that tells me the usage. However from the monthly bills I noticed that I was getting further and further into credit. This I explained to myself was because two of my daughters have moved out, so my usage was probably lower. So I requested a refund from Octopus. They wanted details and pictures of my meters. When I supplied these they then said that the gas meter was not transmitting a reading to them, so I gave them the current reading (this was last December). They gave me a refund and said that they had passed details to their "smart meter team". Out of curiosity (I have better things to do than constantly monitor energy usage) - today I checked the gas meter and the reading it is giving is exactly the same as the one I gave to Octopus in December. So despite keeping my water and radiators hot (with gas CH) I have apparently used no gas at all for two months (and possibly some before that.)
I have been open and honest with Octopus - and told them of the issue. I await their response. But I would like some opinions as to my liability - i.e. what are they going to try and charge me for - an estimate based on past usage etc etc
Thank you

Yes, there is a regulator approved methodology for working this out when a meter stops working.

Is the gas meter wholly within your property?  If you're in a flat and it's in an external cupboard or meter room  it could be a neighbour's meter.
